The answer is axial precession. Axial precession refers to
the very slow motion of the Earth’s axis, which almost requires twenty-six
thousand (26,000) years to complete a full rotation. This Axial Precession is
caused by the effects of gravitational pull from the Sun and the Moon towards
the Earth.
the answer is speaker it transform electrical energy into sound energy
Answer:
The height of the hill is 0.46 m.
Explanation:
Given;
mass of the child and sled, m = 50 kg
initial velocity of the sled, u = 0
final velocity of the sled, v = 3 m/s
The height of the high is calculated from the law of conservation of energy;
P.E at top = K.E at bottom
mgh = ¹/₂mv²
gh = ¹/₂v²
Therefore, the height of the hill is 0.46 m.
Heat will cause evaporation and some other things like a wild fire so it is the heat
Answer:
40.91 m/s
Explanation:
w = angular velocity of the ball about the elbow joint = 30.3 rad/s
r = radius of circular turn = distance of the ball from the elbow joint = 1.35 m
v = linear velocity of the ball
Linear velocity of the ball is given as
v = r w
Inserting the values given above in the equation
v = (1.35) (30.3)
v = 40.91 m/s
