<span>Because the moon has no atmosphere, it is not possible for geologic events to occur on the moon.</span>
The answer is 30m. <span>If one wave of 10m amplitude meets constructively with another wave of amplitude 20m, the new amplitude is 30m. </span>When wave<span> interfere </span>constructively<span>, their </span>amplitudes<span> are added. So the </span>amplitude<span> in this case is </span>10 m+20 m<span>=30 m .</span>
Given :
Two charges q1 and q2 exert a force of 20 N on each other.
To Find :
If the charge of q1 is doubled, what will the new force be?
1) 40 N 2) 80 N 3) 20 N 4) 10 N
Solution :
We know, electrostatic force between two charges is given by :
Here, F = 20 N.
Now, if is doubled :
Therefore, if the charge of q1 is doubled, new force will be 40 N.
Answer:
The pressure is .
Explanation:
Calculate the area of the rectangular container.
A=LB
Here, L is the length and B is the breadth.
Put L=0.125 m and B= 0.209 m.
A=(0.125)(0.209)
The expression for the pressure in terms of area and force is as follows;
Here, P is the pressure and F is the force.
Put and F= 4.47 N.
Therefore, the pressure of the given sample is .
