I THINK C
Explanation:
BECAUSE A Light Emitting Diode (LED) glows even when a weak electric current passes through it.
Answer:
Explanation:
As we know that amplitude of forced oscillation is given as
here we know that natural frequency of the oscillation is given as
here mass of the object is given as
angular frequency of applied force is given as
now we have
The force of the person is 90 newtons away from the wall.
<h3>What is force?</h3>
Force can be defined as the product of mass and acceleration.
To calculate the force of the person when pushing off the wall, use the formula below.
Formula:
- F = ma................. Equation 1
Where:
- F = Force off the wall
- m = mass of the person
- a = acceleration of the person
From the question,
Given:
- m = 90 kg
- a = 1 m/s² off the wall
Substitute these values into equation 1
- F = 90×1
- F = 90 Newtons away from the wall
Hence, the force of the person is 90 newtons away from the wall.

I think the first one is the correct answer
note: are not always 100% true
Answer:
Explanation:
<u>Given:</u>
velocity of the ball first and ball second,
angle of projection of the first ball,
∵The balls should land at the same point,
∴their range of projectile,
As we know for the range of projectile:
∵ we have equal range in both the cases
