Taking Earth to be a perfect sphere, find the linear speed of a point located on the 32nd parallel, as a result of Earth’s rotation. The 32nd parallel north is a circle of latitude that is 32 degrees north of the Earth's equatorial plane. Take the Earth's radius to be 6,371,000 m

Answers

The linear speed of a point located on the 32nd parallel, as a result of Earth’s rotation is 392.91 m/s

We find the linear speed of a point on the 32nd parallel from v = rω where r = radius of 32nd parallel north = Rcos32° (since it is the radius of the small circle at the 32nd parallel) where R = radius of earth = 6,371,000 m and ω = angular speed of the earth = 2π/T where T = period of earth = 24h = 24 × 60 × 60 s = 86400 s.

So, v = rω

v = Rcos32° × 2π/T

v = 2πRcos32°/T

substituting the values of the variables into the equation, we have

v = 2πRcos32°/T

v = 2π × 6,371,000 m × cos32°/86400 s.

v = 2π × 6,371,000 m × 0.8480/86400 s.

v = 33947512.5035 m/86400 s

v = 392.91 m/s

So, the linear speed of a point located on the 32nd parallel, as a result of Earth’s rotation is 392.91 m/s

A. The TV remote has a greater difference in electric potential energy


B. The car battery has more kinetic energy


C. The TV remote has more kinetic energy


D. The car battery has a greater difference in electric potential energy

Answers

A 12 volt car battery will produces more current than a 1.5 volt battery for a TV remote because the car battery has a greater difference in electric potential energy than a 1.5 Volt battery. The correct answer is D

The potential difference between any two point in a circuit is the work done when one coulomb of charge moves from one point to the other. Potential difference is a kind of electrical pressure difference between two point.

The difference in electric potential in a 12 Volt battery is greater than the difference in electric potential in a 1.5 Volt battery.

According to Ohm's law, Voltage supplied is proportional to current produced. That is, V = lR. Where R = resistance.

A 12 volt car battery will produces more current than a 1.5 volt battery for a TV remote because the car battery has a greater difference in electric potential energy than a 1.5 Volt battery.

The launch speed of a projectile is three times the speed it has at its maximum height.what is the elevation angle at launch?

Answers

Answer:

Given: a projectile of initial launch velocity(V) and launch angle ∅ and no air resistance. At the maximum height, the projectile would have a zero contribution of speed from the vertical component(Vy) Therefore, if we say Vx=Vcos∅ is the only speed the projectile has at the instant of maximum height then we can replace Vx with 1/5V and write 1/5V=Vcos∅. Solving for the the launch angle ∅, gives Inverse Cos(1/5)=78.5 degrees.

Which key phrase below would imply that an object has no (0) initial velocity?
1) smoothly
2) in motion
3) backwards
4) from rest
5) uniformly


I assume number 4.​

Answers

The key phrase which describes zero (0) initial velocity is from rest.

When the velocity of an object at initial time is zero (0), it implies that the change in the displacement of the object with time is zero

[tex]v= \frac{\Delta x}{\Delta t} \\\\v_0 = 0[/tex]

Generally, when an starts its motion from rest, the initial velocity of the object will be zero. As the object acquires more momentum, the velocity increases with time.

Thus, we can conclude that the key phrase which describes zero (0) initial velocity is from rest.

An eraser is tied to a string swung in a horizontal circle. Identify the type of force which causes this object to travel along a circular path.

Answers

Answer:

A centripetal force

Explanation:

The type of force in the given scenario is tension. The correct option is c.

What is tension force?

Tension is defined in physics as the pulling force conveyed axially by a string, cable, loop, or similar material, or by every end of a rod, truss member, or similar three-dimensional object.

Tension can also be defined as the action-reaction pair of forces acting at each end of said elements.

Newton's second law states that the tension in the rope must equal the weight of the backed mass.

Tension, the normal force, and friction are all examples of contact forces.

Since the weight is not moving, the acceleration is zero. Even if the acceleration is not zero, this equals zero.

Thus, the correct option is c.

A 25 kg chair initially at rest on a horizontal floor requires a 165 N horizontal force to set it in motion. Once the chair is in motion, a 127 N horizontal force keeps it moving at a constant velocity.​

Find the coefficient of static friction between the chair and the floor.​















b. Find the coefficient of kinetic friction between the chair and the floor.​

Answers

a. The coefficient of static friction between the chair and the floor is 0.67.

b. The coefficient of kinetic friction between the chair and the floor is 0.52.

Given the following data:

Mass of chair = 25 kgHorizontal force A = 165 NHorizontal force B = 127 N

Scientific data:

Acceleration due to gravity = 9.8 [tex]m/s^2[/tex]

a. To find the coefficient of static friction between the chair and the floor:

Mathematically, the force of static friction is given by the formula;

[tex]F_s = uF_n = umg[/tex]

Where;

Fs represents the force of static friction.μ represents the coefficient of static friction.[tex]F_n[/tex] represents the normal force.g is the acceleration due to gravity.mμ is the mass of an object.

Making μ the subject of formula, we have:

[tex]u=\frac{F_s}{mg}[/tex]

Substituting the given parameters into the formula, we have;

[tex]u=\frac{165}{25 \times 9.8} \\\\u=\frac{165}{245}[/tex]

μ = 0.67

b. To find the coefficient of kinetic friction between the chair and the floor:

Note: The normal force would be the same as above.

[tex]u_k = \frac{F_k}{F_n} \\\\u_k = \frac{127}{245}\\\\u_k =0.52[/tex]

Write four questions and below the answers about water and air resistance.

Answers

Questions And Answers About Air Resistance.

Question 1: What is Air resistance?

Answer: Air resistance is a force that is caused by air. The force acts in the opposite direction to an object moving through the air. A lorry with a flat front will experience high air resistance while a sports car with a streamlined shape will experience lower air resistance, allowing the car to go faster.

Question 2: What causes air resistance?

Answer: Air resistance, also known as drag, is a force that is caused by air, the force acts in the opposite direction to an object moving through the air. It is where air particles hit the front of the object slowing it down. The more surface area, the more air particles hit it and the greater the resistance.

Question 3: How can air resistance be overcome?

Answer: Two ways to reduce air resistance are stated: reducing the area in contact with air (by the cyclist ducking down or cycling behind someone else) and by being more streamlined (wearing smoother surfaces or a more streamlined helmet).

Question 4: What happens when air resistance increases?

Answer: As it gains speed, the object's weight stays the same but the air resistance on it increases. There is a resultant force acting downwards. Eventually, the object's weight is balanced by the air resistance. There is no resultant force and the object reaches a steady speed – this is known as the terminal velocity.

Questions And Answers About Water Resistance.

Question 1: What is Water resistance?

Answer: Water resistance is a type of force that uses friction to slow things down that are moving through water. ... Water resistance occurs because of the particles in the liquid. As an object moves through a liquid, it collides with the particles which cause it to slow down.

Question 2: What causes water resistance?

Answer: Water resistance doesn't have to be just water, however, it can happen to objects moving through any type of fluid. Water-resistance happens because of the particles in water or the fluid. As the object moved through it collides with the particles which try to slow it down.

Question 3: How is water resistance useful?

Answer: Like friction and air resistance, it SLOWS THINGS DOWN, trying to stop them from moving. Water resistance can also be useful at times. When you are swimming and you push against the water with your hands, the water-resistance pushes back and helps you to move forward. This also happens when you use oars to row a boat.

Question 4: Does water-resistant mean waterproof?

Answer: The technical definition of water-resistant is that it's able to resist the penetration of water to a certain degree, but not entirely. Waterproof technically means that it's impermeable to water, no matter how much time it spends in the water.
