What is the net force of the diagram?

Answer:

500x

Explanation:

A microscope had an eyepiece magnification of 10x

The objective lens magnification is 50x

Therefore the total magnification can be calculated as follows

= 10 × 50

= 500x

Hence the total Magnificattion is 500x

Answer:

[tex]\boxed {\boxed {\sf 4 \ meters}}[/tex]

Explanation:

Gravitational potential energy can be found using the following formula:

[tex]E_P=m*g*h[/tex]

where m is the mass, g is the gravitational acceleration, and h is the height.

The mass of the tiger is 12.5 kilograms. The gravitational acceleration on Earth is 9.8 m/s².

[tex]m= 12.5 \ kg \\g= 9.8 \ m/s^2\\E_p= 490 \ kg*m^2/s^2[/tex]

Substitute the values into the formula.

[tex]490 \ kg*m^2/s^2 = 12.5 \ kg * 9.8 \ m/s^2 *h[/tex]

Multiply 12.5 kg and 9.8 m/s²

[tex]490 \ kg*m^2/s^2 = 122.5 \ kg *m/s^2 *h[/tex]

Since we are trying to solve for h, we must isolate it. Since h is being multiplied by 122.5, we must divide both sides by that number because the inverse of division is the inverse of multiplication.

[tex]\frac{490 \ kg*m^2/s^2} { 122.5 \ kg *m/s^2}= \frac{ 122.5 \ kg *m/s^2 *h }{ 122.5 \ kg *m/s^2}[/tex]

Note that when dividing, the kg*m/s² will cancel each other out, but a m (meter) will be left.

[tex]\frac{490 \ m }{122.5} =h[/tex]

[tex]4 \ m =h[/tex]

The tiger was 4 meters above the ground.

Question:

The flow of air caused by _____ and the Coriolis effect creates distinct _____ on Earth's surface.

Answer:

Explanation:

The flow of air caused by variations in the rate at which the different parts are heated up as well as the Coriolis effect combine to create distinct wind patterns on Earth's surface.

The Coriolis Effect is used to describe a "force" that causes things (like objects, planes, air currents) traveling long distances around the Earth to appear to bend as they move rather than in a straight line.

Answer:

C = - 1.625 i + 6.06 j

Explanation:

Positive angles are measured counterclockwise.

Positive angles are measured counterclockwise. To determine the component on the x axis we use the cosine of the angle while to determine the component on the y axis we use the sine of the angle.

[tex]C_{x}=6.28*cos(105)=-1.625\\C_{y}=6.28*sin(105)=6.06\\[/tex]

C = - 1.625 i + 6.06 j

Answer:

62.5m

Explanation:

Given parameters:

Time  = 5s

Acceleration  = 5m/s²

Unknown:

Distance traveled by car  = ?

Solution:

To solve this problem, we use one of the motion equations as given below:

     S  = ut + [tex]\frac{1}{2}[/tex] at²

S is the distance traveled

t is the time taken

u is the initial velocity  = 0m/s

a is the acceleration

Now insert the parameters and solve;

      S = (0 x 5) + ([tex]\frac{1}{2}[/tex] x 5 x 5²) = 62.5m

Answer:

The car's average speed is 70.8 mph

Explanation:

The given parameters are;

The total distance traveled = 885 miles

The time of travel = 12.5 hours

The average speed is given by the following equation;

[tex]Average \ speed = \dfrac{Total \ Distance \ traveled}{Total \ time \ taken \ to \ travel \ the \ distance}[/tex]

Therefore, we have;

[tex]Average \ speed = \dfrac{885 \ miles}{12.5 \ hours} = 70.8 \ miles \ per \ hour[/tex]

Therefore, the car's average speed = 70.8 mph.

Answer:

The car's average speed is 70.8 mph

Answer: 1.1x10^21 photons / sec

Explanation:energy per photon

.. E / photon = hc / L = (6.626x10^-34 J x sec) x (3.00x10^8 m/sec) / (6.5x10^-6m)

.. E / photon = 3.06x10^-20 J / photon

then

.. (32.7 watts) x (1 J/sec / 1watt) x (1 photon / 3.06x10^-20J) = 1.1x10^21 photons / sec

The number of photons are emitted per second will be "1.07".

According to the question,

Power,

           = 32.8 J/s

Wave length,

          = [tex]6.5\times 10^{-6}[/tex]

As we know,

→ [tex]E = \frac{hc}{\lambda}[/tex]

By substituting the values, we get

      [tex]= \frac{32.8}{\frac{(4.42\times 10^{-34})(3\times 10^{-4})}{4.5\times 10^{-6}} }[/tex]

      [tex]= \frac{32.8}{3.055e}[/tex]

      [tex]= 1.07[/tex]

Thus the above answer is correct.

Explanation:

Answer:

The velocity of motion at which the occupants of the car appear to weigh 20% less than their normal weight is approximately 19.81 m/s

Explanation:

The given parameters are;

The curvature of the hill, r = 200 m

Due to the velocity, v, the occupants weight = 20% less than the normal weight

The outward force of an object due to centripetal (motion) force is given by the following equation;

[tex]F_c = \dfrac{m \times v^2}{r}[/tex]

Where;

r = The radius of curvature of the hill = 200 m

Given that the weight of the occupants, W = m × g, we have;

[tex]F_c = 0.2 \times W = 0.2 \times m \times g[/tex]

[tex]\therefore 0.2 \times m \times g = \dfrac{m \times v^2}{r}[/tex]

v = √(0.2 × g × r)

By substitution, we have;

v = √(0.2 × 9.81 × 200) ≈ 19.81

The velocity of motion at which the occupants of the car appear to weigh 20% less than their normal weight ≈ 19.81 m/s.

The velocity is 19.81 m/sec at which the occupants of the car appear to weigh 20% less than their normal weight and this can be determined by using the formula of centripetal force.

Given :

A car is going over the top of a hill whose curvature approximates a circle of radius 200 m.

The centripetal force acting on the car is given by the formula:

[tex]\rm F_c = \dfrac{mv^2}{r}[/tex]   ---- (1)

where m is the mass of a car, v is the velocity of the car and r is the radius of curvature.

Now, it is given that the occupants of the car appear to weigh 20% less than their normal weight that means:

[tex]\rm F_c = 0.2\times W[/tex]

[tex]\rm F_c = 0.2 \times m \times g[/tex]   --- (2)

Now, equate equation (1) with equation (2).

[tex]\rm \dfrac{mv^2}{r}=0.2\times m \times g}{}[/tex]

[tex]\rm v = \sqrt{0.2\times g \times r }[/tex]

[tex]\rm v = \sqrt{0.2\times 9.81 \times 200 }[/tex]

v = 19.81 m/sec

The velocity is 19.81 m/sec at which the occupants of the car appear to weigh 20% less than their normal weight.

Answer:

Time Saved = 0.374 h = 22.4 min

Explanation:

First we calculate the time required at old speed limit:

s = v₁t₁

where,

s = distance from Portland to Bangor = 215 km

v₁ = old speed limit = 88.5 km/h

t₁ = time taken with old speed limit = ?

Therefore,

215 km = 88.5 km/h (t₁)

t₁ = (215 km)/(88.5 km/h)

t₁ = 2.429 h

Now, we calculate the time taken at the new speed limit:

s = v₂t₂

where,

s = distance from Portland to Bangor = 215 km

v₂ = new speed limit = 104.6 km/h

t₂ = time taken with new speed limit = ?

Therefore,

215 km = 104.6 km/h (t₂)

t₂ = (215 km)/(104.6 km/h)

t₂ = 2.055 h

So, the time saved will be:

Time Saved = t₁ - t₂ = 2.429 h - 2.055 h

Time Saved = 0.374 h = 22.4 min

Answer:

The net and only force acting on the ball thrown up into the air at half of its maximum height is the weight  of the ball

Explanation:

When the ball is rising in the air, the force, F, acting on it is given by the product of the mass, m × acceleration, a

The acceleration of a body thrown in the air = Gravitational acceleration = g = Constant

Therefore;

The force acting on the body thrown in the air F = Constant = m × g (downwards)

The force acting on the ball thrown up into the air at half of its maximum height = The mass of the ball × The acceleration due to gravity = The weight  of the ball.

Explanation:

Answer:

43.2J

Explanation:

Q = m × c × ∆T

Where:

Q = amount of energy

m = mass (grams)

c = specific heat capacity

∆T = change in temperature

Mass = 5.0g

Specific heat capacity of Silver (Ag) = 0.240 J/g°C

We need to convert the temperature from Kelvin (K) to °C

Initial temperature = 298 - 273 = 25°C

Final temperature = 334 - 273 = 61°C

Q = 5 × 0.240 × (61°C - 25°C)

Q = 1.2 × 36

Q = 43.2J
