Answer:
Explanation:
the object will not move as the force exerted is not sufficient enough to overcome its force of friction
Newton's Third Law- For every action there is an equal and opposite reaction... Does this answer your question? If not, I can explain further...
The force that must be exerted on the outside wheel to lift the anchor at constant speed is 6.925 x 10⁵ N.
<h3>Force exerted outside the wheel</h3>
The force exerted on the outside of the wheel can be determined by applying the principle of conservation of angular momentum as shown below.
∑τ = 0
- Let the distance traveled by the load = 1.5 m
- Let the radius of the wheel or position of the force = 0.45 m
∑τ = R(mg) - r(F)
rF = R(mg)
0.45F = 1.5(21,200 x 9.8)
F = 6.925 x 10⁵ N.
Thus, the force that must be exerted on the outside wheel to lift the anchor at constant speed is 6.925 x 10⁵ N.

Answer:
a) 0.477 W/m²
b) 13.407 N/C
c) 18.96 N/C
Explanation:
P = Power = 150 W
r = Distance = 5 m
ε₀ = Permittivity of space = 8.854×10⁻¹² F/m
a) Average intensity
∴ Average intensity is 0.477 W/m²
b) Rms value
∴ Rms value of the electric field is 13.407 N/C
c) Peak value
∴ Peak value of the electric field is 18.96 N/C
Yes, that's correct. Newton's formula for the gravitational force, stated in this form, was used by Cavendish to measure ' G '.
