Answer:
Angular acceleration rad/s^2
Explanation:
Given
Initial Angular velocity (w1) rad/s
Final Angular velocity (w2) rad/s
Time taken to change velocity from w1 to w2 seconds
Angular acceleration is equal to the change in angular velocity to the time taken for making thing change
Hence, Angular acceleration
rad/s^2
Answer:
Saturated, water-bearing materials often exist in horizontal layers beneath the land surface. Since rivers, in time, may cut vertically into the ground as they flow, the water-bearing layers of rock can become exposed on the river banks. Thus, some of the water in rivers is attributed to flow coming out of the banks.

-- A change in speed can be either speeding up or slowing down. These effects can be caused by the gas pedal or the brake pedal.
-- Velocity is made of the car's speed and direction. These can be changed by the gas pedal, the brake pedal, or the steering wheel.
Answer:
The Tension in the cable is 392.3N. The vertical reaction at the hinge (fixed end) is 850.3N.
The tension in the cable was calculated using the principles of moments which states that the total sum of the clockwise moments is equal to the total sum of anticlockwise moments on a system in equilibrium.
Explanation:
Sum of Clockwise moments = Sum of anticlockwise moments
900×1 + 200×3 + 90×6 = T×Sin120 × 6
900 + 600 + 540 = 5.20T
T = 2040/5.20 = 392.3N
Summing vertical forces
R + Tsin120 = 900 +200+90
R + 392.3sin120 = 1190
R + 339.7 = 1190
R = 1190 - 339.7
R = 850.3N
