The spring constant of the spring is 240.05 N/m according to the information on the question above. This problem can be solved using the spring potential energy formula which stated as PE = 1/2 * k * x^2 where PE is the spring's potential energy, k is the constant of the spring, and x is the stretched displacement<span>. (Calculation: 240.05=35*2/(0.54^2) </span>
Answer:
I haven’t done this in a while but i think b
Explanation:
B: reliable
nuclear power is not cheap or clean, it also cannot be built anywhere i don’t think if not b then i suppose try D next
150x2=300 90x2=180
the plane is travelling at 180mph
The right answer for the question that is being asked and shown above is that:
(1) <span>b. the light will reach the front of the rocket at the same instant that it reaches the back of the rocket.
</span>(2) <span>a. the light will reach the front of the rocket before it reaches the back of the rocket.
</span>(3) <span>b. less than Δt
</span>(4) <span>c. the length of your spaceship is getting longer.
(5) </span><span>c. 1.20c</span>
