What equation can be used to calculate the time of impact when you have the impulse and force applied to an object

Answers

Answer 1

Answer: Impulse = (force) x (length of time the force acts).

Divide each side by 'force' :

Length of time of the impact = (Impulse) / (force) .

Answer 2

Answer:

Answer is below

Explanation:

I = F △t

Doing a warmup before exercise is important because it

Answers

Doing a warm-up before exercise is important because it strengthens your body and gets your body ready for the exercise you are about to do. If you do not do a warm-up, your body may grow tired a bit more quickly.

Two objects move toward each other because of gravitational attraction. As the objects get closer and closer, the force between them _____. A. remains constant B. decreases C. increases

Answers

As 2 objects get closer and closer due to the gravitational attraction, the force between them C. increases.

Two objects move toward each other because of gravitational attraction. To understand the gravitational force, we need to consider Newton's law of universal gravitation, which states that every particle attracts every other particle in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. Mathematically,

$F = G (m_1m_2)/(r^(2) )$

where,

F: gravitational force
G: gravitational constant
m₁: mass of object 1
m₂: mass of object 2
r: distance between centers of the masses

As the objects get closer, the distance between them decreases, and consequently the gravitational force increases.

As 2 objects get closer and closer due to the gravitational attraction, the force between them C. increases.

Answer:

C. increases

Explanation:

Law of Universal Gravitation

This law establishes that bodies, by simply having mass, experience a force of attraction to other bodies with mass, called gravitational force or gravitational force.

The gravitational force between two bodies is directly proportional to the product of their masses and inversely proportional to the square of the distance that separates them.

$F_(g) =G((M*m)/(r^(2) ) )$ Formula (1)

where:

G is the universal gravitation constant, G = 6.67 · 10-11 N · m² / kg²

M and m are the masses of the bodies that interact (kg)

r is the distance that separates them. (m)

Problem development

As objects get closer and closer the distance (r) that separates them decreases and because M, m and G remain constant, in formula (1):

$F_(g) =G((M*m)/(r^(2) ) )$

, if r decreases then Fg increases.

Through which substance will sound travel fastest?
the ground
the ocean
the air

Answers

Sound waves travel fastest through the ground.

What is meant by a longitudinal wave ?

A longitudinal wave is a form of wave in which the medium vibrates parallel to the direction of the wave.

Here,

The displacement of the medium moves with the wave motion in the same direction.

Sound waves are longitudinal waves because, the direction of the energy transport is parallel to the oscillations of the sound waves.

Since, it is created by compressions and rarefactions in the air, sound waves are known as longitudinal waves. The air particles vibrate in a direction that is parallel to the direction of propagation.

The sound waves require a medium to propagate.

Solids and liquids have the quickest sound wave propagation rates, whereas gases have the slowest. Gases are very loosely packed while liquids are not as securely packed as solids. Sound moves through solids much more quickly than it does through gases due to the distance between the molecules.

Hence,

Sound waves travel fastest through the ground.

Answer: The correct option is the ground.

Explanation:

Sound is a longitudinal wave. In longitudinal wave, the particles vibrate parallel to the direction of the propagation of the wave.

It needs medium to travel. It can travel in solid, liquid and gas.

Sound wave travels faster in solid in comparison to liquid.

It travels slowest in air.

Ground is a denser medium. Here, the sound wave travels faster in comparison to the ocean and the air.

Therefore, the correct answer is the ground.
