The net force that is applied to the passenger during the elevator acceleration is 218.75 N.
<h3>What is net force?</h3>
This is the single force obtained from the combinatiion of two or more forces
To calculate the net force that is applied to the passenger during the elevator's acceleration, we use the formula below.
Formula:
- F = m(v-u)/t............ Equation 1
Where:
- F = force
- m = mass
- v = Final velocity
- u = initial velocity
- t = time.
From the question,
Given:
- m = 70 kg
- u = 0 m/s
- v = 12.5 m/s
- t = 4 s
Substitute these values into equation 1
Hence, The net force that is applied to the passenger during the elevator acceleration is 218.75 N.

Answer:
It increases to three times its original value. Given the same radius of wire and other constant property. current is directly proportional to the magnetic field.
B1=B2
MoI1/2pir=MoI2/2pir; cancel the same values on both sides
B2/B1=6/2 =3
Explanation:
Answer
graph 2
Explanation
Velocity is the rate of change of displacement.
Velocity = (change in displacement)/(change is time)
In graph 2, the gradient of the curve is positive, indicating that the velocity is positive.
Acceleration is the rate of change of velocity.
The steepness of the slope of the same graph (graph 2) is decreasing. This shows that the velocity is decreasing hence a negative acceleration.
Answer:
Emissions per second = 0.36
Explanation:
Please find the attached question
Solution
Given
Let X be the rate of background emission.
X = B/t
Where B = 36
And t = 100
X = 36/100 = 0.36
