Answer:
The charge pass through your hair dryer is 3000 C.
Explanation:
Given that,
Power = 1200 W
Voltage = 120 V
Flow time = 5 min
We need to calculate the current
Using formula of power
Put the value into the formula
We need to calculate the charge pass through your hair dryer
Using formula of current
Put the value into the formula
Hence, The charge pass through your hair dryer is 3000 C.

Calories would denote the amount of heat.
Givens are:
Mass = 500 g
t0 = 20C
tf = 30C
C = 1 cal/gC
Formula:
Q=MCt
500g (1cal/gC) 10C= 5000 cal

Answer:
Gauge pressure rise = 292 Pa
Explanation:
We are given;
Diameter of the water droplet is d = 2mm = 0.002m
Radius = 0.002/2 = 0.001
Surface tension; σ = 73 mNm = 73 x 10^(-3)m
So we have to find the pressure rise.
Now, pressure rise is given by the formula ;
ΔP = P_inside - P_atmosphere = 4σ/r
Where r is radius.
Thus, plugging in the relevant values, we have;
ΔP = (4 x 73 x 10^(-3))/0.001 = 292 pa
