Answer:
20m/s
Explanation:
acceleration=final velocity-initial velocity/time
4.0m/s²=v m/s-0m/s/5.0sec
5.0sec×4.0m/s²=v m/s-0m/s×5.0m/s/5.0m/s
20m/s=v
Given the the current flowing in the circuit and the elapsed time, the charge that passes through the LED is 1260 Coulombs.
<h3>What is Current?</h3>
Current is simply the rate of flow of charged particles i.e electrons caused by EMF or voltage.
If a charge passes through the cross-section of a conductor in a given time, the current I is expressed as;
I = Q/t
Where Q is the charge and t is time elapsed.
Given the data in the question;
- Time elapsed t = 1hr = 3600s
- Current I = 350mA = 0.35A
We substitute our given values into the expression above to determine the charge.
I = Q/t
Q = I × t
Q = 0.35A × 3600s
Q = 1260C
Therefore, given the the current flowing in the circuit and the elapsed time, the charge that passes through the LED is 1260 Coulombs.

Answer:
The Answer is blue
Electromagnetic waves are produced by light. They are made up of oscillating magnetic and electric fields. They include radio waves, microwaves,infrared waves, visible light, ultraviolet, x-rays and gamma rays. Electromagnetic waves carry energy. radio waves are used in communications to send signals from one place to another.Microwaves use high energy that increases the motion of molecules in your food. Infrared waves are used in things like night vision cameras or a tv remote. The human body has a temperature that produces radiation which can be picked up by an infrareds device.Ultraviolet light ( like from the sun) can cause sunburn and skin cancer . That.s why it’s important to wear sunscreen and sunglasses to protect our bodies and and our eyes. X-rays are very high energy and like ultraviolet rays can cause damage to the body. But x-rays used at the right amount can be safe on the tissues and organs in our bodies. Hope this helps !
