A lot because of the way that the force that it would be
Explanation:
The rod is uniform, so the center of gravity is at the center, or 0.75 m from the end. The wedge is 0.5 m from the end, so the center is 0.25 m from the wedge.
Sum the torques about the wedge (it may help to draw a diagram first). Take counterclockwise to be positive.
∑τ = Iα
W (0.25 m) − (100 N) (0.50 m) = 0
W = 200 N
Sum the forces in the y direction.
∑F = ma
F − 100 N − 200 N = 0
F = 300 N
Answer:
(I). The initial rotation rate is 4.29 rad/s.
(II). The revolutions is 3932.
Explanation:
Given that,
Time = 1.6 h
Angular velocity = 41 rpm
(I). We need to calculate the initial rotation rate in rad/s
(II). We need to calculate the revolutions
Using formula of revolutions
Hence, (I). The initial rotation rate is 4.293 rad/s.
(II). The revolutions is 3932.
Answer:
m=ρV
V=4/3 * pi * r3
V=1.3 * 3.14 * 3.9^3
V=242.14 cm^3
m=7.58 * 242.14
m=1.8 kG
Explanation:
1. We calculate volume for sphere.
2. Then we calculate mass of sphere.
The charge? If you mean valance electrons, the answer is 8. All compounds must be equal to that of a noble gas.
