Answer:

letter e.

Explanation:

because i know its not too deep

Answer:

They weight the same, they're both 1 kilogram

The weight of the given objects is the same since they have equal mass.

The weight of an object is the gravitational pull of earth on the object. Weight is vector quantity because it varies from place to place due to difference in acceleration due to gravity.

W = mg

W = 1 x 9.8

W = 9.8 N

W = mg

W = 1 x 9.8

W = 9.8 N

Thus, the weight of the given objects is the same since they have equal mass.

Answer:To understand the regional and local climates of Colorado, you must begin with a basic knowledge of Colorado's topography. Colorado lies astride the highest mountains of the Continental Divide. Nearly rectangular, its north and south boundaries are the 41° and 37° N. parallels, and the east and went boundaries are the 102° and 109° W. meridians. It is eighth in size among the 50 states, with an area of over 104,000 square miles. Although known for its mountains, nearly 40 percent of its area is taken up by the eastern high plains.

Of particular importance to the climate are Colorado's interior continental location in the middle latitudes, the high elevation of the entire region, and the mountains and ranges extending north and south approximately through the middle of the State. With an average altitude of about 6,800 feet above sea level, Colorado is the highest contiguous State in the Union. Roughly three-quarters of the Nation's land above 10,000 feet altitude lies within its borders. The State has 59 mountains 14,000 feet or higher, and about 830 mountains between 11,000 and 14,000 feet in elevation.

Complete question:

A 0.144 kg baseball approaches a batter with a speed of 20m/s . The batter lines the ball directly back to the pitcher with a speed of 30m/s . Find the impulse exerted on the ball . If the bat and ball were in contact for 0.012 sec , find the average force exerted on the ball by the bat

Answer:

(1) The impulse exerted by the ball is 7.2 kg.m/s

(2) The average force exerted on the ball by the bat is 600 N.

Explanation:

Given;

mass of the baseball, m = 0.144 kg

velocity of the baseball, v₁ = 20 m/s

velocity of the batter, v₂ = -30 m/s (opposite direction to the ball's speed)

The impulse exerted by the ball is calculated as follows;

J = ΔP = mv₁ - mv₂

ΔP = m(v₁ - v₂)

ΔP = 0.144 [20 - (-30)]

ΔP = 0.144 ( 20 + 30 )

ΔP = 0.144 (50)

ΔP = 7.2 kg.m/s

The average force exerted on the ball by the bat is calculated as;

[tex]F = \frac{\Delta P }{t} \\\\where; t \ is \ time \ of \ contact= 0.012 \ s\\\\F = \frac{7.2}{0.012} \\\\F = 600 \ N[/tex]

Answer:

Newton's second Law of motion

Answer: B An action-reaction force pair

Explanation: Took the exam

The arrows in this photograph represent: An action-reaction force pair. Hence, option (B) is correct.

When two bodies interact, they exert an equal and opposite force on one another in accordance with Newton's third law of motion. Action-reaction forces are made up of these forces.

"When one body exerts a force on the other body, the first body experiences a force that is equal in magnitude in the opposite direction of the force which is exerted," according to Newton's third law of motion.

According to the above assertion, there are always two forces operating on the objects involved in an interaction. The forces are of identical magnitude, but the direction of the force acting on the first object is different from the direction acting on the second.

Explanation:

The statement that best describes a perfectly inelastic collision is

C. A surfer falls off of his surfboard when a wave hits him.

A collision is the interaction between two bodies in such a way that the momentum and velocity of one body gets changed due to the presence of other body. There are three types of collision-

1. Elastic collision

2. Inelastic collision

3. Perfectly inelastic collision.

In all types of collision , the momentum of the system before collision and after collision always remains same or we can say that momentum is conserved in collisions

An elastic collision is the one in which kinetic energy is also conserved and coefficient of restitution is one. Both the bodies move separately with different velocities after elastic collision.

In inelastic collision  there is a loss of kinetic energy and coefficient of restitution is less than one.

In perfectly inelastic collision there is maximum loss of kinetic energy and coefficient of restitution is zero. Both the bodies stick together after collision and move with same velocity

Coefficient of restitution is the  ratio of  relative velocity of separation after collision to relative velocity of approach before collision.

A surfer falls of his surfboard when a wave hits him is an example of perfectly inelastic collision because in this when water hits the surfers he falls of and sticks to the water , and will also now move with the velocity of water .

So  when the surfer falls off his surfboard when a wave hits him is perfectly inelastic collision.
