1350kgm/s
Explanation:
Given parameters:
Mass of Sam = 75kg
Velocity = 18m/s
Unknown:
Momentum = ?
Solution:
Momentum is the property of a moving body with respect to its mass and velocity.
Objects in motion have momentum. The more the velocity of a body, the more its momentum. Also, the more the mass of an object, the more momentum it possess.
Momentum is a function of the mass and the velocity of a body
Momentum = mass x velocity
Momentum = 75 x 18 = 1350kgm/s

Answer:
The last statement is false.
Explanation:
Photons (Electromagnetic radiation) are released when electrons drop from a higher energy lever to a lower energy level. Therefore the opposite insinuated by the last statement is wrong.
Answer:
520000 or 520000 pa
Force = 520N
Area of contact = 0.001
Pressure: 520000 or 520000
Yes, for balance.hope this helped.
Gases at pressure are released by rockets as they travel towards space. According to Newton's third law, the combustion chamber's exhaust gases push the rocket with an accelerating force known as the thrust.
<h3>Explain exactly Newton's Third Law:</h3>
According to Newton's third law, if an object A pulls on an object B, then object B must exert an equal-sized and opposite-direction force on the first thing directed in the opposite direction. This law illustrates a symmetry in nature whereby forces always occur in pairs and whereby no body can exert a force without also being subjected to one.
<h3>What are Newton's 3rd law examples?</h3>
Action and response are always equal but always move in the opposite direction, according to Newton's third law of motion. A human walking on the ground, a hammer driving a nail, a magnet attracting a paper clip, and a horse pulling a cart are all examples of Newton's third rule of motion.
