Answer:
The magnetic field at the location is
Explanation:
Given that,
Potential difference = 1320 V
Distance = 0.008 m
We need to calculate the velocity
Using conservation of energy
Electric potential energy lost = kinetic energy gained
Put the value into the formula
We need to calculate the magnetic field at the location
Using formula of magnetic field
Put the value into the formula
Hence, The magnetic field at the location is
Answer:
D. its acceleration is zero
Explanation:
Acceleration can be defined as the rate of change of the velocity of an object with respect to time.
This simply means that, acceleration is given by the subtraction of initial velocity from the final velocity all over time.
Hence, if we subtract the initial velocity from the final velocity and divide that by the time, we can calculate an object’s acceleration.
Mathematically, acceleration is given by the equation;
In this scenario, a stone is thrown straight up. While the stone is rising its acceleration is zero because it's initial velocity is zero and it's until the stone reaches its highest point before the acceleration becomes constant and acting downward.
