When hockey players push the puck along the ice it slides causing heat which melts the ice causing the friction against the ice to be less.
Not sure but i will say D
Answer:
N = 23.4 N
Explanation:
After reading that long sentence, let's solve the question
The contact force is the so-called normal in this case we can find it by writing the translational equilibrium equation for the y axis
N - w₁ -w₂ =
N = m₁ g + m₂ g
N = g (m₁ + m₂)
let's calculate
N = 9.8 (0.760 + 1.630)
N = 23.4 N
This is the force of the support of the two blocks on the surface.
Im pretty sure the jet airplane is faster
We could use the formula for the Power supply in order to find the wattage capacity and it would be:
P = V²/R or P = V * I
Hope this helps!
