The net force on the block parallel to the incline is
∑ F = -mg sin(θ) = ma
where m is the mass of the block, g = 9.8 m/s² is the acceleration due to gravity, θ is the angle the incline makes with the horizontal, and a is the acceleration of the block. Solving for a gives
a = -g sin(θ)
so the block would slide down the incline with acceleration
a = - (9.8 m/s²) sin(30°) = -4.9 m/s²
Mechanical advantage (MA = slope/height)
here length of slope = 9Hheight = H so mechanical advantage = ---- 9H/H= 9
Displacement is your answer :)
Answer:
0.69 ohm
Explanation:
Heat generated per second, H = 50 cal/s
Potential difference, V = 12 V
Let R is the resistance of coil.
The formula for the heat is given by
R = 0.69 ohm
