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:
5833.33
Explanation:
= Angular acceleration
= Number of revolutions
= Initial angular speed = 0
t = Time taken = 2 s
Final angular speed
From the equation of rotational motion we have
The number of revolutions is 5833.33
According to the question, the object is placed at 2F
The ray diagram is shown in the figure attached.
According to the figure:
Object AB is at 2F₁
First, we draw a ray parallel to principal axis.
So, it passes through focus after refraction.
We draw another ray which passes through optical center.
So, the ray will go through without any deviation.
Where both refracted rays meet is point A' and the image formed is A'B'
This image is formed at 2F₂
We can say that:
- Image is real.
- Image is inverted.
- Image is exactly the same size as the object.
Answer:
