Answer:
The amount of force acting on the spring.
Explanation:
Here, Fspring= kΔx is a equation denoting the amount of force acting on the spring.
where, k = spring constant.
Δx= change in the length of the spring.
so, for every Δx change in spring length, kΔx force acts on the spring.
Accelerating pretty sure but be sure to double check the answer
Answer:
75.5degrees
Explanation:
Magnitude of magnetic flux= BA
If rotated through an angle= BAcos theta
= (0.25)BA=BAcos theta
= costheta= 0.25
= theta= cos^-1 0.25
=75.5degrees
Explanation:
Table A: Calculation of Density for Regularly Shaped Solids
Table tennis ball Golf ball
"Mass

Diameter (cm)
Radius (cm)
Estimated volume (cm3)
Estimated density (g/cm3)
"Prediction of buoyancy
Circle one."
"Observation of buoyancy
Circle one."
Initial volume of water (cm3)
Final volume of water (cm3)
Change in volume (cm3)

Heat must be added to raise the temperature from 20.0 •C to 82 •C is
Q= (4200 x 1.8 + 880 x 1.3) x (82 - 20) = 539648J
