Answer:
Given the point of maximun electric power of the hair dryer 1500 (w); The circuit breaker won´t trip at all
Explanation:
The most simplyfied relation between power, voltage and current is:
Electric power (in watts) =Voltage (in volts) * current (in ampers)
In the case of P= 1500 (w) and V= 120 (v) we have:
I = 1500/120 (a) = 12,65 (a)
This value is far away of 20 (a) (the nominal trip current
I already said it but its reactivity
F=9/5C+32 is the formula for Celsius to Fahrenheit.
The absolute pressure is given by the equation,

Here,
is absolute pressure,
is atmospheric pressure and
is vacuum pressure.
Therefore,

The gage pressure is given by the equation,
.
Thus,

<span>Mass of the ball is m = 0.10kg
Initial speed of the Ball v = 15m/s
a. When the ball is at maximum height the velocity is 0
Momentum of ball = mass x velocity
Momentum = 0.10kg x 0 = 0
b. Getting the maximum height,
Using the conservation of energy equation KEinitial = mgh
1/2mVin^2 = mgh => h = v^2/2g
h = 15^2/2x9.8 = 11.48m => Half Height h = 5.96m
Applying the conservation of energy equation at halfway V^2 = 2gh
V = square root of (2x9.8x5.96) => V = square root of (116.816)
So the velocity at the half way V = 10.81 m/s
Momentum M = m x V => M = 0.10 x 10.81 => M = 1.081kg-m/s</span>
