This question involves the concepts of charge and potential difference.
The net charge on the balloon is "2.6 x 10⁻⁸ C".
<h3>Net Charge on Balloon</h3>
The balloon has a shape of a sphere. Therefore, the formula for the charge on the surface of a sphere can be used here, as follows:
where,
- Q = net charge = ?
- r = radius of balloon = 15 cm = 0.15 m
- V = potential difference = 1560 V
- = permittivity of free space = 8.85 x 10⁻¹² C²/N.m²
Therefore,
Q = (4π)(8.85 x 10⁻¹² C²/N.m²)(0.15 m)(1560 V)
Q = 2.6 x 10⁻⁸ C = 26 nC

Answer:
9800 Pa
Explanation:
Data: pressure-?
Force- mass ×acceleration
= 50× 9.8m/s^2
=490N
Area= 500cm^2=0.05m^2
pressure= force/ area
p=F/A
P= (490N)/( 0.05m^2)
=9800 Pa

Time
Generally the equation for Tension is mathematically given by
Therefore
, toward the center of the circle
Option C
Explanation:
Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time (Δt), represented by the equation v = Δs/Δt. Speed (or rate, r) is a scalar quantity that measures the distance traveled (d) over the change in time (Δt), represented by the equation r = d/Δt.
