The formula we use to calculate acceleration is: v-u/t. Which is the ending speed taken away by the original speed all divided by the duration of the acceleration.
So if we substitute the numbers in, it will look like this: (7-0)/3 which gives you 2.33m/s^2
Answer:
The current in the coil is 60 Ampere.
Explanation:
Given:
Number of turns in the coil is N = 25
Dimension of the coil = 15cm X 12cm
magnitude of magnetic field = 0.20T
angle in the xy plane is θ = 0 degree
torque τ = 5.4 N-m
To find:
current in the coil is i = ?
Solution:
The torque acting on the coil is given by
=>
Converting cm to m
12 cm = 0.12 m
15 cm = 0.15 m
The area of the coil is
A = 0.12 X 0.15
A =
Substituting the values
=>
=>
=>
=>
=>
=>
=> i = 60 A
Answer:
False
Explanation:
Ultraviolet, infrared and visible light are all parts of the electromagnetic spectrum of radiation. They are all electromagnetic waves, characterized by different wavelengths:
- Ultraviolet have wavelength between approximately 10 nm and 400 nm
- Visible light have wavelength between approximately 400 nm and 780 nm
- Infrared have wavelength between approximately 800 nm and 1100 nm
The human eye is able to see only a part of the electromagnetic spectrum, which corresponds to the visible light part, while it is not able to see ultraviolet nor infrared radiation.
The potential difference between the plates will be 1552 Volts.
<h3>What is a potential difference?</h3>
Voltage, or the difference in electric potential between two points, is defined as the amount of labor per unit of charge needed to move a test charge between the two points.
Given that a 3.7-f capacitor that stores sufficient energy to operate a 75.0-w
The potential difference will be calculated by the formula below:-
Q = I t
Where I = charge / time
Q = V * C
V C = I t
V = I t / C
V = 75 C/s x 60 sec / 2.9 faraday
V = 1552 Volts

Answer:
K = 80.75 MeV
Explanation:
To calculate the kinetic energy of the antiproton we need to use conservation of energy:
<em>where : is the photon energy, : are the rest energies of the proton and the antiproton, respectively, equals to m₀c², : are the kinetic energies of the proton and the antiproton, respectively, c: speed of light, and m₀: rest mass.</em>
Therefore the kinetic energy of the antiproton is:
<u>The proton mass is equal to the antiproton mass, so</u>:
Hence, the kinetic energy of the antiproton is 80.75 MeV.
I hope it helps you!
