Answer:
Following are the option are the correct option to the given question
- Plane landing on an aircraft carrier.
-
Rain sticking to a window.
-
Two train cars coupling together.
Explanation:
In the inelastic collisions is the kinetic energy is not preserved because of the some internal friction.In the elastic collision there is shortage of the kinetic capacity.
- When the airplane is landing it has always been in contact with the surface to relieve the inelastic collision condition.
- When then rain falls the clinging to the door once it intersect with as well so it is satisfied the condition of inelastic collision.
- When the two train or cars collide there is loss of kinetic energy so it is satisfied the condition of inelastic collision.
- All the other option is not the example of inelastic collision that's why they are incorrect option.
Answer:
option C
Explanation:
given,
helicopter moving at the speed of = 15 m/s
time before the package hit the ground = 12 s
height above the ground = ?
using the equation
hence, the height above the ground will be approximately equal to 530 m
correct answer is option C
Answer:
t = 3.44 s
Explanation:
We are given;
Fired from rest, and so; u = 0 m/s
Final speed; v = 170 m/s
Height above flat ground; y_o = 58 m
Height at starting point; y = 0 m
Thus, from Newton's equation of motion, we have;
y - y_o = ut - ½gt²
(since it's motion is against gravity)
Plugging in the relevant values, we have;
0 - 58 = 0 - (½ × 9.8 × t²)
-58 = -4.9t²
t² = 58/4.9
t = √(58/4.9)
t = 3.44 s
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
