Answer:
a. 250kg I think it's the right answer. hope it helps:)
I think metal, steel and copper.
Answer:
The answer should be <u>WORK </u>
<em>(Hope this Helps)</em>
Explanation:
work is equal to the product of force and distance.
W=F*S
W=Work
F=Force applied
S=Distance
Q stands for heat energy (Joules) hope this helps!
Answer:
The spring constant is 215.6 N/m.
Explanation:
Given that,
Distance = 39 cm
Compresses length = 29 cm
Mass = 2.2 kg
We need to calculate the distance
Using formula of distance

Put the value into the formula
We need to calculate the spring constant
Using formula of restoring force


Where, F = force
x = distance
Put the value into the formula


Hence, The spring constant is 215.6 N/m.
