What is the velocity of a 24 kg object with 108 kg m/s of momentum?

A) 3 m/s
B) 4.5 m/s
C) 6 m/s
D) 84 m/s

Answers

Answer:

The velocity of the object is 4.5 m/s

Explanation:

Momentum is equal to mass times velocity.  We can rearrange that relationship to say that velocity is equal to momentum divided by mass.  With that we can say:

v = 108 kg m/s / 24kg

v = (108 / 24) m/s

v = 4.5 m/s

Answers

Answer:

Atoms are made up of even smaller particles called protons, electrons & neutrons (sub-atomic particles)

Atoms are made up of smaller particles called subatomic particles.

What is an Atom?

An atom is defined as the smallest indivisible particle of an element. It is made of subatomic particles which are:

NeutronProton Electron

Now the Neutron and Proton make up the nucleus which is at the core(middle) of the atom whole the electron rotates around the orbits that  surrounds the nucleus.

The Neutron has no charge.

The Proton is positively charged.

The electron is negatively charged.

How do plants obtain the carbon dioxide required for photosynthesis?​

Answers

Answer:

Explanation:

Carbon dioxide in photosynthesis Plants get carbon dioxide from the air through their leaves. The carbon dioxide diffuses through small holes in the underside of the leaf called stomata . (singular: stoma. plural: stomata) The lower part of the leaf has loose-fitting cells to allow carbon dioxide to reach the other cells in the leaf.

Answer:

Plants get the carbon dioxide they need from the air through their leaves. It moves by diffusion through small holes in the underside of the leaf called stomata These let carbon dioxide reach the other cells in the leaf, and also let the oxygen produced in photosynthesis leave the leaf easily.

Acceleration due to gravity =9.8 m/s/s

GPE = m*g*h​

Answers

Answer:

GPEb=67.86% of initial GPE at point a

Explanation:

It depends on how massive the ball is, but I can still give an answer comparing original GPE at point A to new GPE at B

GPEa=m*9.8*140

GPEa=1372(m)

GPEb=m*9.8*95

GPEb=931(m)

GPEb=0.6786*GPEa

newton’s 2nd law
———

Newton's second law states that the acceleration of an object is directly related to the force on it, and inversely related to the mass of the object. You need more force to move or stop an object with a lot of mass (or inertia) than you need for an object with less mass. .

Why is ultraviolet radiation considered more dangerous to humans than infrared radiation?
ANSWER:Ultraviolet radiation has a shorter wavelength than infrared radiation, and thus, the waves have higher energy. This allows them to penetrate the first layers of skin on humans and can mutate the DNA in the cells of the skin. This can result in cancer because of the mutations caused by the ultraviolet radiation.

What happens as a bungee jumper gets closer to Earth's surface?
A. Gravity decreases
B. His mass increases
C. Air resistance decreases
D. His velocity increases

Answers

Answer:

Velocity increases

Explanation:

Gravity is constant, except when discussing "apparent weight"

Mass is constant here

Air resistance would actually increase

Velocity DOES increase, because Earth is pulling the jumper downwards with an unbalanced force. The unbalanced force creates acceleration (-9.81 m/s^2), which means his velocity is increasing constantly.

a force of 25N acts on an object. The work done by the force is 400J. How far dose the object move in the direction of the force?

A. 6.3cm
B. 16cm
C. 16m
D. 10km​

Answers

Answer:
C
Explanation:
d=w/f
d=400/25
d= 16

The distance moved by the object in the direction of the force is equal to 16 m. Therefore, option (B) is correct.

What is the work?

Work can be demonstrated as the energy employed when a force is exerted to move an object through a specific distance. The work done depends upon both the exerted force on the object and the displacement.

The action of the force when the object is moving in a straight line in the direction of the exerted force over a distance 'd'.

W= F ×d

Where 'd' is the displacement, 'F' is the applied force and W is the work done.

Given, the work done by the applied force, W = 400 J

The force applied on the object, F = 25 N

The distance moved by the object, d = W/F

d = 400/25

d = 16 m

Therefore, the object moves a distance of 16 m in the direction of the force.

Explanation:

Net force is the sum total of forces acting on an object.

The Fn which is the net force is

450+ (-250) + (-600)+ 600+ 0 + 250 + (-450)

= 450-250+(-600)+ 600+0+250-450

= 0N

The net force is 0
