Answer:
Explanation:
Kinetic energy is the energy an object possesses due to motion. It is calculated with the following formula.
The mass of the object is 4.7 kilograms. The velocity of the object is 7 meters per second.
Substitute the values into the formula.
Solve the exponent.
- (7 m/s)²= 7 m/s * 7 m/s = 49 m²/s²
Multiply the numbers together.
Convert the units. 1 kilogram square meter per square second is equal to 1 Joule.
The object has <u>115.15 Joules</u> of kinetic energy.
The following expression is applicable:
Max. inductor energy = Max. capacitor energy
Where;
Max. inductor energy = LI^2/2, with L = 20.0 mH, I = 0.400 A
Max. capacitor energy = CV_max^2/2, C = 0.150 micro Faraday, V_max = Max. potential difference
Substituting;
LI^2/2 = CV^2/2
LI^2 = CV^2
V^2 = (LI^2)/C
V_max = Sqrt [(LI^2)/C] = Sqrt [(20*10^-3*0.4^2)/(0.15*10^-6)] = 146.06 V
Answer:
B. a region of similarly oriented electrons in motion
Explanation:
Acceleration due to gravity is different in every location, because gravity itself is different in every location.
Here are a few values of gravitational acceleration in various places:
-- Surface of Jupiter . . . 24.8 m/s²
-- Surface of Mars . . . 3.7 m/s²
-- Surface of the Sun . . . 274 m/s²
-- Surface of Earth . . . 9.8 m/s²
-- In orbit 300 miles above the Earth's surface . . . 8.5 m/s²
-- Surface of Earth's Moon . . . 1.6 m/s²
Answer:
<h2>Electricity has many uses in our day to day life. It is used for lighting rooms, working fans and domestic appliances like using electric stoves, A/C and more. All these provide comfort to people. In factories, large machines are worked with the help of electricity.</h2>
