Answer:
C. Copper
Explanation:
F = Force on string
= Intial length of string
A = Area of string
E = Young's modulus of material
Change in length is given by

It can be seen that the change in length is inversely proportional to the Young's modulus of the material.
Here




So, copper will stretch the least.
Answer:
""gravity. the force that pulls on objects and causes acceleration if the objects are not balanced by an opposing force. speed. distance traveled per unit time. Newton's Second Law of Motion.""
Explanation:
A). The ball was moving at zero speed at the peak.
b). The acceleration of the ball was 9.8 m/s² downward, from
the time the hand threw it until the time the hand caught it.
c). see the answer to b).
d). see the answer to b).
e). The ball was in the air for 2 (22.5/9.8) = 4.6 seconds.
f). The ball was moving down at 22.5 m/s when it was caught.
Answer:
<h3>The answer is 7.0 mL</h3>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula

From the question
mass = 35 g
volume = 5 g/cm³
We have

We have the final answer as
<h3>7.0 mL</h3>
Hope this helps you
Answer:
voltages across the resistor and the capacitor are same
Explanation:
given data
resistor and a capacitor = parallel
power supply = 120 V
solution
as we have given resistor and a capacitor both are connect in parallel in connection
so when resistor and a capacitor are parallel as directly across the source so the voltages across both components will be same or equal
and that is equal to the source 120 V DC
so answer is both are same
