T = 2*V₀*sin (α) / g
t = 2*1770*sin (26.3°) / 9.8 ≈ 2*1770*0.443 / 9.8 ≈ 160 s or 2.7 min
Explanation:
Given that,
Charge on a spherical drop of water is 43 pC
The potential at its surface is 540 V
(a) The electric potential on the surface is given by :
r is the radius of the drop
(b) Let R is the radius of the spherical drop, when two such drops of the same charge and radius combine to form a single spherical drop. ATQ,
Now the charge on the new drop is 2q. New potential is given by :
Hence, the radius of the drop is and the potential at the surface of the new drop is 856.79 V.
Answer:
It's B, because of process of elimination:
A: The rower would be applying force to the oar not the other way around. So that's immediately out.
C: If the force of the oar applies to the water, the force of the water cannot apply to the oar.
D: Same as why A is incorrect.
So B is the only one left.
the answer is a
