a) 27 N right.
b) 3 N right
c) 2 N left.
d) 3 N left.

Pretty sure it’s d because 15N - 12N= 3N probably not right considering I haven’t done in class physics in almost 2 years

Standing and holding a barbell that has a mass of 100kg at a height of 2m involves being done on the barbell to maintain
the position.

Answers

Answer:

1960Joules

Explanation:

Since we are not told what too find, we can as well find the Gravitational Potential Energy.

GPE = mass * acceleration due to gravity * height

GPE = 100*9.8 * 2

GPE = 980*2

GPE = 1960Joules

Hence the gravitational potential Energy is 1960Joules

1.) True or False.
The two forces in an action-reaction pair are always equal in strength.
2.) True or False.
The two forces in an action-reaction pair act in the same direction.
3.) True or False.
Action-reaction force pairs act on the same object.
4.) True or False.
Action-reaction force pairs act simultaneously.

Answers

Answer:

Explanation:

According to Newton's third law of motion, forces always act in equal but opposite pairs. Another way of saying this is for every action, there is an equal but opposite reaction. This means that when you push on a wall, the wall pushes back on you with a force equal in strength to the force you exerted. 1.True 2.falues 3.true 4. not really sure on this one

A 1202-kg car is stopped at a stoplight. Inside, the car has three occupants. The two passengers have a mass of 75 kg each, while the driver has a mass of 105 kg. The driver steps on the gas pedal, and the car begins to accelerate at a rate of 2.5 m/s2 . What is the force that the engine is applying to the car?

Answers

Answer:

F = 63.25 N

Explanation:

a = 2.5 m / s ²

m = 25.3 kg

F =?  

We calculate the force.

F = ma

F = (25.3 kg) (2.5m / s²)

F = 63.25 N

Solution.

F = 63.25 N

Explanation:

The mass of mass A the diagram .the frame joining the mass is massless.

What is Mass?

The unique location in an object or system that can be used to describe how the system reacts to outside forces and torques is referred to as the "center of mass" or "center of gravity" in a uniform gravity field.

The idea of the center of mass is that it is the average of all the masses divided by the distances between them. With regard to the torques produced, that is comparable to balancing a seesaw around a pivot point in one plane.

Therefore, The mass of mass A the diagram .the frame joining the mass is massless.

If you use a lever to lift a boulder 0.25m, while applying 350 N on the lever which moves 1.5 m down on your side. What is the weight of the boulder? (F1d1 = F2d2) 87.5 N 131 N 525 N 2100 N

Answers

Answer:

2100 N

Explanation:

From the question,

Using the formula

F₁d₁ = F₂d₂..................... Equation 1

Where F₁ = Weight of the Boulder, d₁ = distance moved by the Boulder, F₂ = Force applied on the lever, d₂ = distance moved by the lever.

make F₁ the subject of the equation

F₁ = F₂d₂/d₁.................... Equation 2

Given: F₂ = 350 N, d₁ = 0.25 m, d₂ = 1.5 m

Substitute these values into equation 2

F₁ = 350(1.5)/0.25

F₁ = 2100 N

I was playing goalie in a soccer league and made a save. The ball was traveling at 14 m/s and has a mass of 0.45 kg. How muck kinetic energy did the ball have when it hit me

Answers

Answer:

Kinetic energy = 44.1 J

Explanation:

Given:

Velocity of ball = 14 m/s

Mass of ball = 0.45 kg

Find:

Kinetic energy

Computation:

An item's kinetic energy is force it has as a result of its motion. It is the amount of work necessary to move a body of a known volume from rest to a specified velocity.

Ke = (1/2)(m)(v²)

Ke = (1/2)(0.45)(14²)

Ke = (1/2)(0.45)(196)

Kinetic energy = 44.1 J

What is the wavelength of visible light emitted at 4.2 x 10^8 Answer in units of M

Answers

Answer:

0.714 m

Explanation:

From the question,

v = λf......................... Equation 1

Where v = velocity of visible light, f = frequency of visible light, λ = wave length of visible light.

make λ the subject of the equation

λ = v/f.................. Equation 2

Given: f = 4.2×10⁸ Hz

Note: Light is an electromagnetic wave, and all electromagnetic waves travels with the same speed (3×10⁸ m/s)

Constant: v = 3×10⁸ m/s

Substitute these values into equation 2

λ = 3×10⁸/4.2×10⁸

λ = 0.714 m

Answers

Answer:

Amplitude is a measure of the size of sound waves. It depends on the amount of energy that started the waves. Greater amplitude waves have more energy and greater intensity, so they sound louder. The same amount of energy is spread over a greater area, so the intensity and loudness of the sound is less.
