The correct answer is Matter is made up of atoms and has mass.
The frequency f of a wave is defined as the inverse of the period T:
The clock in the problem has a waveform with period
. Therefore, its frequency is
Answer:
Yes it is a solid
Explanation:
It just has unusual properties.
Does it float when you drop it? then it is not a gas.
Does it pour into any container as water does? Then it is not a liquid.
So it's a solid.
And it can change it's shape
The diameter of a ball is 3.8 cm.
Because 400/3.8 = 105.26,
each dimension of 400 m can accommodate 105 balls.
Similarly, because 300/3.8 = 78.95,
each dimension of 300 m can accommodate 78 balls.
The total number of balls is 105*105*78 = 859,950
Answer: 859,950 balls
Answer:
Normal force=mg
Explanation:
The reaction force of weight is the normal force.
in order to find the normal for we need to write all the forces and set it equal to the net force:
N-mg=ma (since it is a constant speed the a=0)
N=mg
