Option (B)is correct.
Alternating electric and magnetic fields has electromagnetic radiation that travel in the form of a wave.
The varying or alternating electric field produces the varying magnetic field.This varying magnetic field in turn produces varying electric field . Thus these varying electric and magnetic fields travel in the form of electromagnetic waves. These electromagnetic waves travel with the velocity of light.These are transverse in nature.
<span> A. stops accelerating </span>
<span> B. stops speeding up </span>
<span> C. experiences equal forces of gravity and air resistance </span>
<span> D. all of the above</span>
A full lake is dropping at its constant rate, meaning it is unchanging over time.
After 4 weeks’ time, it already dropped 3 feet.
Now, let’s solve for the Unit rate based on the given data.
=> 3 feet in 4 weeks
=> Unit rate is 3 feet per 4 weeks
=> in 4 weeks there are (7 * 4) = 28 days
=> 3 feet / 28 days
=> the Unit rate is .107 feet / day
The tearing of paper is physical as it's still paper even when you tear it. A chemical reaction is when the substance is chemically change. ... When paper is burn, the cellulose in the air reacts with the oxygen to form carbon dioxide and water.
Therefore it's chemistry.
Number of neutrons: atomic mass - atomic number
Element X's atomic mass is 79 and its atomic number is 39. Subtract 39 from 79 to find how many neutrons Element X has.
79 - 39 = 40
Element X has 40 neutrons.

Since, the stone is released and it falls towards the sky, its initial velocity is zero
As per equation
, we will evaluate "t"
Substituting the given values in above equation, we get
Velocity
centripetal acceleration
