c. target specific areas for improvement
d. vary exercise activities over time

Answers

Answer 1

Answer: a. address all components of fitness

According to the exercise principle of balance, a workout should address all components of fitness.
NOT:
b. focus on balance and coordination
c. target specific areas for improvement
d. vary exercise activities over time

Answer 2

Answer: According to the exercise principle of balance, a workout should:

a. address all components of fitness

Explanation:

The Balance Principle dictates that each one training should be properly proportioned so as to realize best results. This broad principle operates at several levels of human performance.
All things moderately apply to sports coaching moreover general health and well being
This principle suggests that the proper mixture of coaching activities, diet, and healthy way habits are needed for the best functioning

2. A roller coaster at an amusement park has a dip that bottoms out in a vertical circle of radius r. A passenger feels the seat of the car pushing upward on her with a force equal to five times her weight as she goes through the dip. Of r = 21.5 m, how fast is the roller coaster traveling at the bottom of the dip?

Answers

Answer: $v=√(4gr)$

Explanation:

Given

Passenger feels the seat of the car Pushing upward with a force equal to five times her weight

Therefore

$N-mg=(mv^2)/(r)$

it is given $N=5mg$

where N=normal reaction

$5mg-mg=(mv^2)/(r)$

thus $v=√(4gr)$

Car A has a mass of 1,200 kg and is traveling at a rate of 22 km/hr. It collides with car B. Car B has a mass of 1,900 kg and is traveling in the same direction at 25 km/hr. Which of the following statements is true?A) The momentum before the collision is equal to the momentum after the collision.

B) The momentum before the collision is greater than the momentum after the collision.

C) The momentum before the collision is less than the momentum after the collision.

Answers

The car A has a mass of 1200 kg.

The car B has the mass of 1900 kg.

It is given that velocity of car A is given as 22 Km/hr

The car B has the velocity of 25 Km/hr.

Let the mass of two bodies are denoted as $m_(1) \ and\ m_(2)$

Let the velocity of cars A and B are denoted as $v_(1) \ and\ v_(2)$

The momentum before collision is-

$p_(i) =m_(1) v_(1) +m_(2) v_(2)$

[Here p stand for momentum.]

We are asked to calculate the final momentum of the system after collision.

The answer of the question is based law of conservation of linear momentum.

As per law of conservation of linear momentum the sum total linear momentum for an isolated system is always constant.Hence irrespective of the type of collision[elastic and inelastic],the momentum of the system is always constant which is a universal truth.

Let after the collision the velocity of A and B are $v'_(1) \ and\ v'_(2)$

Hence the final momentum of the system is-

$p_(f) = m_(1) v'_(1) +m_(2) v'_(2)$

As per the law of conservation of linear momentum, the initial and final momentum must be equal i.e

$p_(i) =p_(f)$

$m_(1) v_(1) +m_(2)v_(2) =m_(1) v'_(1) +m_(2) v'_(2)$

Hence the option A is right.

A
This principle is known as the law of conservation of momentum.

What is the main difference between a longitudinal wave and a transverse wave? a longitudinal wave travels faster than a transverse wave. a transverse wave always has a larger amplitude than a longitudinal wave. the motion of the medium is parallel to a longitudinal wave and perpendicular to a transverse wave. the frequency is directly proportional to wavelength in a longitudinal wave but inversely proportional in a transverse wave.?

Answers

When waves propagate in a medium, then the motion of the medium is parallel to a longitudinal wave and perpendicular to a transverse wave.

What are sound waves?

A sound wave is caused by disturbances in the path of propagation of the particles. These disturbances can be caused in the medium like solid, liquid, and air.

There are two main types of waves namely - Transverse waves and longitudinal waves.

Transverse Waves - These waves are the waves where the particles in a medium travel perpendicular to the direction of the wave. These waves do not require a medium to travel and can travel in a vacuum also.

Longitudinal waves - These waves are the waves where the particles of the medium travel parallel to the direction of the wave and these waves require a medium to travel and hence, cannot travel in a vacuum.

Thus, we can conclude that the motion of the medium is parallel to a longitudinal wave and perpendicular to a transverse wave.

Answer: The correct answer is the motion of the medium is parallel to a longitudinal wave and perpendicular to a transverse wave.

Explanation:

There are two main types of waves:

1. Transverse Waves: These waves are the waves where the particles in a medium travel perpendicular to the direction of the wave. These waves do not require a medium to travel and can travel in vacuum also. For Example: Light waves.

2. Longitudinal waves: These waves are the waves where the particles of the medium travel parallel to the direction of the wave and these waves require a medium to travel and hence, cannot travel in vacuum. For Example: Sound waves.

From the given options, the correct answer is the motion of the medium is parallel to a longitudinal wave and perpendicular to a transverse wave.

What is a transverse wave?a. particles that travel parallel to the direction of energy movement
b. particles that travel in a reverse direction to the direction of energy movement
c. particles that travel perpendicular to the direction of energy movement
d. particles that travel in an intersecting direction to the direction of energy movement
