Explanation:
Given
Mass of crate is m=574 kg
The crate is raised up to a height of 1.3 m
time taken t=2 s
Work done to raise the crate is equal to the change in its potential energy
Magnetic Flux is the magnetic force acting on a unit positive charge moving perpendicular to the magnetic field with a unit velocity
<h3>
What does magnetic flux depend on ?</h3>
The magnetic flux or field lines linking a coil depends on;
- The magnetic field strength
- The number of turns of the coil
According to the question, the Magnetic force acting on a unit positive charge moving perpendicular to the magnetic field with a unit velocity is called magnetic flux
To obtain a large induced electromotive force, we cause a coil of many turns to move at a high speed across a strong magnetic field.
According to Faraday's law, which state that whenever there is a change in the magnetic lines of force, an electromotive force is induced, the strength of which is proportional to the rate of change of the flux linked with the circuit.
Therefore, Magnetic Flux is the magnetic force acting on a unit positive charge moving perpendicular to the magnetic field with a unit velocity

Answer:
Fusion is the process that powers the sun and the stars. It is the reaction in which two atoms of hydrogen combine together, or fuse, to form an atom of helium. In the process some of the mass of the hydrogen is converted into energy. ... The sun and stars do this by gravity.

Elephant
Explanation:
has a larger mass which equates to greater momentum
Answer:
Tension, T = 105.09 N
Explanation:
Given that,
Length of the string, l = 0.33 m
Mass of the string,
Fundamental frequency, f = 440 Hz
The expression for the speed in terms of tension is given by :
So, the tension in the string is 105.09 N.
