The circuit breaker will tripped. Details below
<h3>What is power? </h3>
This is defined as the rate in which energy is consumed. Electrical power is expressed mathematically as:
Power (P) = voltage (V) × current (I)
P = IV
<h3>How to determine the total power</h3>
The following data were obtained from the question:
- Power of heater = 1.50×10³ W
- Power of toaster = 750 W
- Power of grill = 1×10³W
- Total power = ?
Total power = power of heat + power of toaster + power of grill
Total power = 1.50×10³ + 750 + 1×10³
Total power = 3250 W
<h3>How to determine whether or not the circuit breaker will tripped</h3>
To determine if the circuit breaker will tripped or not, we shall determine the current used by the appliances. Detail below:
- Total power (P) = 3250 W
- Voltage (V)= 120 V
- Current (I) =?
P = IV
Divide both side by V
I = P / V
I = 3250 / 120
I = 27.08 A
Since the current used by the three appliances (i.e 27.08 A) is greater than the current the circuit breaker (i.e 25 A), can with stand,thus, the circuit breaker will tripped

Answer:
The answer is
<h2>2560 J</h2>
Explanation:
The kinetic energy of an object given it's mass and velocity can be found by using the formula
where
m is the mass
v is the velocity
From the question
m = 80 kg
v = 8 m/s
The kinetic energy is
We have the final answer as
<h3>2560 J</h3>

The mass of water that must be raised is 
Explanation:
Since the process is 70% efficiency, the power in output to the turbine can be written as
where 
is the power in input.
The power in input can be written as
where
W is the work done in lifting the water
t = 3 h = 10,800 s is the time elapsed
The work done in lifting the water is given by
where
m is the mass of water
is the acceleration of gravity
h = 45 m is the height at which the water is lifted
Combining the three equations together, we get:
Where
And solving for m, we find:
