Answer:

b. Continental-oceanic

Explanation:

The Earth's crust has been divided into a series of plates. These plates move at a different rate or speed in different directions.

These plates are divided by the boundary between them which are of three types: convergent, transform and divergent.

The convergent boundaries are the one which moves toward each other and the based on the crust they are of three types: continent-continent, ocean-ocean and ocean-continent.

In ocean-continent boundaries, the oceanic plate is denser compared to the continental plate is lighter as a result of which during the process of subduction the oceanic plate sinks beneath the continental plate towards the mantle and melts.

Thus, Option-B is the correct answer.

Answer: F = 106.72 N

Explanation: Newton's Law of Universal Gravitation states that two masses attract each other by a force pointing in a straight line to the center-of-mass of both masses.

It is directly proportional to the masses and inversely proportional to the square of their distance, represented as:

[tex]F=G\frac{m_{1}m_{2}}{r^{2}}[/tex]

where

G is gravitational constant whose value is 6.67x10⁻¹¹ N(m/kg)²

m are masses in kg

r is distance in m

The force between the moon and a person with mass of 66kg is:

[tex]F=6.67.10^{-11}\frac{66(7.34.10^{22})}{(1.74.10^{6})^{2}}[/tex]

[tex]F=\frac{3231.215.10^{11}}{3.0276.10^{12}}[/tex]

F = 106.72 N

The force between a person with mass of 66kg and the moon is 106.72 N.

The strength of the force between person and the moon is equal to 106.6 Newton.

Given the following data:

Scientific data:

To determine the strength of the force between person and the moon, we would apply Newton's Law of Universal Gravitation:

Newton's Law of Universal Gravitation states that the force of attraction (gravitational force) acting between planet Earth and all physical objects is directly proportional to the mass of planet Earth, directly proportional to the mass of the physical object and inversely proportional to the square of the distance separating the Earth's center and that of the physical object.

Mathematically, Newton's Law of Universal Gravitation is given by the formula:

[tex]F = G\frac{M_1M_2}{r^2}[/tex]

Where:

Substituting the given parameters into the formula, we have;

[tex]F = 6.67\times 10^{-11} \frac{(7.34 \times 10^{22} \times 66)}{(1.74 \times 10^{6})^2}\\\\F = 6.67\times 10^{-11} \frac{(4.84 \times 10^{24}) }{3.03 \times 10^{12}}\\\\F = \frac{3.23 \times 10^{14} }{3.03 \times 10^{12}}[/tex]

Force, F = 106.6 Newton.

Both speakers describe the asteroid that hit Earth and caused a massive extinction, including the decimation of the dinosaurs. The speakers describe the size of this asteroid in different terms. Summarize each speaker’s description and explain which one gives you a better picture of the size of this asteroid.  

Debris from the impact orbiting around the Earth shielded sunlight, halting photosynthesis.  

The impact was so extreme that life at ground zero was vaporized.  

tsunamis, landslides, earthquakes, and heat caused by the impact killed organisms near the site of impact.  

Does Carrie Nugent agree with Phil Plait’s assessment that we can defend the Earth from asteroids? Why or why not?  

It seems as if she does agree. I believe she has strong intentions to defend the earth and to prevent there to be any more extinction for any more animals I believe she cares to explore and recover so if she could find a way to use the asteroids to her advantage she would.

Explanation:

6. How does the speaker know that the lump of metal she is holding is an asteroid?

- The speaker knows that the lump of metal she is holding is an asteroid because the patterns formed inside the metal. She explains that the rock is older than the earth and that it is an asteroid. This is due to the patterns formed inside it. These patterns show that it contains metallic crystals that cannot be formed on earth, but instead in space where temperatures mean that molten metal takes billions of years to cool.  The scientists also use representative sampling. This is done when they deal with such large quantities of objects for estimating.

7. How does the speaker “hunt” asteroids? Describe how teams of scientists collect data about asteroids.

- The speaker “hunts” for asteroids by attempting to search for them for scientific use. She analyzes how long ago these rocks were coming across the earth and how many are in the universe.  She also is classifying them by color and shape. Some of the objects can be classified into one or more categories and this could lead to disagreements on where they should or should not be listed. Also, the objects can be difficult to see properly.

8. Both speakers describe the asteroid that hit Earth and caused a massive extinction, including the decimation of the dinosaurs. The speakers describe the size of this asteroid in different terms. Summarize each speaker’s description and explain which one gives you a better picture of the size of this asteroid.

- The asteroid hit at high velocity and effectively vaporized. It made a huge crater, so in the immediate area there was total devastation. A huge blast wave and heatwave went out and it threw vast amounts of material up into the atmosphere. 'It sent soot travelling all around the world.

9. Does Carrie Nugent agree with Phil Plait’s assessment that we can defend the Earth from asteroids? Why or why not?

- I would say that it seems to me as though she does agree. I believe she has strong intentions to defend the earth and to prevent any more extinctions for any more animals. I believe she cares to explore and recover in order to hopefully help find a way to use asteroids to her advantage. On top of that, the object shown is an Irregular galaxy. This can be determined by the fact it has an irregular shape.

Answer:

Photoelectric effect, phenomenon in which electrically charged particles are released from or within a material when it absorbs electromagnetic radiation.

Explanation:

The effect is often defined as the ejection of electrons from a metal plate when light falls on it. In a broader definition, the radiant energy may be infrared, visible, or ultraviolet light, X-rays, or gamma rays; the material may be a solid, liquid, or gas; and the released particles may be ions (electrically charged atoms or molecules) as well as electrons. The phenomenon was fundamentally significant in the development of modern physics because of the puzzling questions it raised about the nature of light—particle versus wavelike behaviour—that were finally resolved by Albert Einstein in 1905. The effect remains important for research in areas from materials science to astrophysics, as well as forming the basis for a variety of useful devices.

The emission of electrons from the surface of a metal by the action of light is called photoelectric effect. This phenomenon indicates the behavior of light as particles called photons.

The phenomenon of ejection of electrons from the surface of a metal when light of a suitable frequency falls on it is called photoelectric effect. Upon striking the surface of metals , light can set up an electric current which current which corresponds to the flow of electrons. This phenomenon is discovered by Einstein

For instance, visible light can cause ejection of electrons from the surface of metal like cesium which has low ionization enthalpy. This phenomenon is related to the observation that if light is considered as particles.

The particles of light is then called as photoelectrons or photons. Photoelectric effect find application in photoelectric cells used in colorimetry, spectrophotometers etc.

Answer:

y = 20 [m]

Explanation:

To solve this type of problem we must use the following equation of kinematics.

[tex]v_{f}^{2} =v_{o}^{2}-2*g*y[/tex]

where:

Vf = final velocity = 0

Vo = initial velocity = 20 [m/s]

g = gravity acceleration = 10 [m/s²]

y = elevation [m]

Now the key to solving this problem is to know that when the stone reaches the maximum height its speed is zero. Therefore the final velocity term is zero.

[tex]0 = (20)^{2}-2*10*y\\20*y=400\\y=20 [m][/tex]

Another important fact is that the sign of gravitational acceleration was taken as negative, since it acts in the opposite direction to the movement of the stone.

Its 150?

Explanation:

5³= 5×5×5

I hope its help :)

First, let's find the resultant, and applicate 2nd law of Newton using the resultant, so:

R = ma

F - Ff = ma

Data:

F = Force = 1150 N

Ff = Friction force = 490 N

m = Mass = 150 kg

a = Aceleraction = ?

Replacing according our data:

1150 N - 490 N = 150 kg * a

660 N = 150 kg * a

660 N / 150 kg = a

a = 4,4 m/s²   ← Aceleration of the object

The normal force IS NOT the resultant force, the normal force's the force between the ground and the object, in another words, is the weight of the object, and for the weight:

w = mg

w = 150 kg * 10 m/s²

w = 1500 N   ← Normal force between object and ground.

Answer:

The new force of attraction would be 36 units

Explanation:

Law of Universal Gravitation

Objects attract each other with a force that is proportional to their masses and inversely proportional to the square of the distance.  

This statement can be expressed with the formula:

[tex]\displaystyle F=G{\frac {m_{1}m_{2}}{r^{2}}}[/tex]

Where:

m1 = mass of object 1

m2 = mass of object 2

r     = distance between the objects' center of masses

G   = gravitational constant: [tex]6.67\cdot 10^{-11}~Nw*m^2/Kg^2[/tex]

Now suppose two given objects attract with a force of F=16 units, thus:

[tex]\displaystyle G{\frac {m_{1}m_{2}}{r^{2}}}=16[/tex]

And now the masses of both objects is tripled, i.e., m1'=3m1, m2'=3m2, and the distance between them is doubled, r'=2r. The new force is:

[tex]\displaystyle F'=G{\frac {3m_{1}3m_{2}}{(2r)^{2}}}[/tex]

Operating:

[tex]\displaystyle F'=G{\frac {9m_{1}m_{2}}{4r^{2}}}[/tex]

[tex]\displaystyle F'=\frac{9}{4}G{\frac {m_{1}m_{2}}{r^{2}}}[/tex]

Substituting the value of the initial force:

[tex]\displaystyle F'=\frac{9}{4}\cdot 16[/tex]

[tex]F'=36\ units[/tex]

The new force of attraction would be 36 units

2m/s^2

a) The acceleration of the car and the bicycle are equal since [tex]\delta V[/tex] for both vehicle is 5km/h and the time taken for both vehicle is also the same 2.5s.

b) The acceleration of the bicycle is 0.556m/s²

Given the data in the question;

Since the bicycle starts from rest

a)

The acceleration of the car and the bicycle are equal since [tex]\delta V[/tex] for both vehicle is 5km/h time taken for both vehicle is also the same 2.5s.

b)

The acceleration of each vehicle

To determine the acceleration for car and the bicycle, we use the first equation of motion:

[tex]v = u + at[/tex]

Where v is the final velocity, u is the initial velocity, a is the acceleration and t is the time.

Now, For the car;

[tex]18.0556m/s = 16.667m/s + ( a + 2.5s )\\\\a = \frac{18.0556m/s - 16.667m/s }{2.5} \\\\a = \frac{1.3886m/s}{2.5s} \\\\a = 0.556 m/s^2[/tex]

Hence, the acceleration of the car is 0.556m/s²

For the bicycle;

[tex]1.38889m/s = 0 + ( a * 2.5s )\\\\a = \frac{1.38889m/s}{2.5s}\\\\a = 0.556m/s[/tex]

Hence, the acceleration of the bicycle is 0.556m/s²
