Answer:Yes
Explanation:
Given
mass
mass
Force of magnitude =17 N
coefficient of static friction
Lower block is glued to floor
Force cos component will try to move the upper block while sin component try to lower the Normal reaction
Normal reaction
and friction force
And force cos component =
As force cos component is more than the friction force therefore it slips w.r.t to lower block
Answer:
2800000J
Explanation:
Parameters given:
Mass = 920kg, weight = 920 * 9.8 = 9016N
Distance = 310m
Angle of inclination = 6.5°
Work done is given as :
W = F*d*cosA
Where A = angle of inclination
W = (9016 * 310 * cos6.5)
W = 2776993.59J
In 2 significant figures, W = 2800000J
Answer:

a) The linear acceleration of the watermelon seed is:
b) The watermelon seed is experimenting a centrifugal acceleration. The coefficient of static friction between the seed and the turntable is calculated by the Newton's Laws:
c) Angular acceleration experimented by the turntable is:
The tangential acceleration experimented by the watermelon seed is:
The linear acceleration experimented by the watermelon seed is:
The minimum coefficient of static friction is:
Answer:
Option D)Potential energy becomes kinetic energy between points P and Q.
Explanation:
The average speed of the boat is 32.8 kilometers per hour.
1 hour= 60 minuets
16.4km=30 minutes
30 mins times 2 is 60
16.4km times 2 is 32.8km
