Answer:
Hey there
Where trying to say that:
Newton's first law gives the concept of force and momentum?
That's false if that's is what you said.
Newton's first law tells us that objects in motion will remain in motion and objects at rest will remain at rest.
Newton's second law gives us the concept of force and momentum.
A) They move slower
Gravity force is determined by mass and the size of the moon. Since the mass of the moon is significantly lower than the mass of Earth, it will pull objects slower. The only object that would fall faster on the moon than on earth is a sheet of paper since there is much, much less air resistance to affect its terminal velocity the way it does on the earth.
Answer:
- radioactive decay is a random process
- use long tongs
Explanation:
Quantum theory has taught us that virtually everything to do with the nature of matter in the universe is a random process. The decay of atomic nuclei is something that makes that randomness "visible" with appropriate instrumentation. As such, the rate of decay will vary over the "short" term. Consequently, it is not surprising to see a variation of a few counts in an activity measurement over a period of a few minutes.

Safety with respect to radioactive materials involves staying as far away from them as possible. The use of long tongs for handling would be appropriate.
The stretch of the OA spring is calculated by the formula of F=-k*(extension) and thats the formula for elasticity. Based on my calculation i came up with an answer of the unstretched length is 2m abd the stiffnes is 310n/m
Answer : The momentum of ball is, 15 kg.m/s
Explanation :
Momentum : It is defined as the motion of a moving body. Or it is defined as the product of mass of velocity of an object.
Formula of momentum is:
where,
p = momentum = ?
m = mass = 1.5 kg
v = velocity = 10 m/s
Now put all the given values in the above formula, we get:
Therefore, the momentum of ball is 15 kg.m/s
