Answer:
A force
Explanation:
A push or a pull is an example of a force and can cause an object to speed up, slow down, etc.. Newton's laws tell us that 1- an object will not change its motion unless a force acts on it 2- the force on an object is equal to its mass times its acceleration. 3- The third law states that for every action (force) in nature there is an equal and opposite reaction.. However, forces like gravity and friction can resist movement.
Answer:
The feeling of weight is one of compression.
Explanation:
All your body is being pulled down by gravity yet your feet ( if standing) or your back or something is holding you up.
Your body is compressed by the PAIR of forces and it is that compression that you feel.
So when you remove the supporting force then all the body is free to move together and there is no compression within you.
Hence you perceive no weight.
Answer: The maximum possible speed v is √2( hν - Ф ) / m
Explanation: You could be referring to the provided explanation, despite the fact that the question isn't comprehensive. When a photon collides with the surface of any metal, it transmits all of its energy to the electron in the atom. The collision causes the electron to travel with a certain amount of kinetic energy. This is referred to as the photoelectric effect. The maximum kinetic energy is calculated using Einstein's equation for the photoelectric effect:
K.E. = hν - Ф
½ mv² = hν - Ф
Hence the maximum possible speed is:
v = √2( hν - Ф ) / m

The force that the washers exert on the force meter will increase as she adds more washers to the meter.
<h3>What is the relationship between force and mass?</h3>
Force exerted by a body is directly proportional to the mass of the body.
Force increases with increase in mass.
The increase in the mass of the washers will result in an increase in the force exerted by the washers.
Therefore, the force that the washers exert on the force meter will increase as she adds more washers to the meter.

Answer:
4.3 N/m
Explanation:
m = 230 g = 0.230 kg, x = 8.2 cm
in 13 oscillations, time taken = 19 s
In 1 oscillation, time taken = 19 / 13 = 1.46 s
By the use of formula of time period , Let k be the spring constant.
0.054 = 0.230 / k
k = 4.26 N/m
k = 4.3 N/m
