Answer:
1. The magnitude of the force from the spring on the object is zero on <em>Equilibrium.</em>
2. The magnitude of the force from the spring on the object is a maximum on <em>The top and bottom.</em>
3. The magnitude of the net force on the object is zero on <em>The Bottom.</em>
4. The magnitude of the force on the object is a maximum on <em>the Top.</em>
Explanation:
<em>1. Because the change in position delta X is zero.</em>
<em>2. Because of delta X.</em>
<em>3. Beacuse, the force of gravity and the force of the spring oppose each other to keep the block at rest, away from the equilibrium position.</em>
<em>4. Because, the force of the spring from compressiom and the force of gravity both act on the mass.</em>
Answer:
option (d)
Explanation:
The relation between the rms velocity and the molecular mass is given by
v proportional to \frac{1}{\sqrt{M}} keeping the temperature constant
So for two gases
The correct answer would be B.
Answer:
Red
Explanation:
I looked at the picture...where it says red is 700
Answer:
Explanation:
Effort x effort distance = load x resistance distance
effort distance = 8 m ,
load = 2000N
resistance distance = 1/2 m = 0.5 m
Putting the values in the equation above
effort x 8m = 2000N x .5
effort = 2000 x 0.5 / 8
= 125 N
force required = 125 N .
