Answer: A controlled experiment is a scientific test done under controlled conditions, meaning that just one (or a few) factors are changed at a time, while all others are kept constant. In some cases, there is no good way to test a hypothesis using a controlled experiment I hope this helps you
Explanation:
An atoms nucleus splits into two smaller nuclei and generally one or more neutrons.
The electromagnetic radiation produced when a charged particle moves spirally in a magnetic field is called <span>synchrotron radiation. This phenomenon occurs due to the fact the particle is accelerated radially (due to the presence of the magnetic field), and every charged particle when it is accelerated emits electromagnetic radiation.</span>
Answer:
We know:
V1 = 0m/s
a = 9.8m/s
D = 16m
So we can solve for V2 with a kinematic equation.
V2^2 = 2a*D
V2^2 = 2(9.8)(16)
V2^2 = 313.6
V2 = 17.7m/s

Answer: faster </h2>
The speed of sound varies depending on the medium through which the sound waves travel. In addition, it varies with changes in the temperature of the medium. This is because an <u>increase in temperature means that the frequency of interactions between the particles that transport the vibration increases</u>, hence this increase in activity increases the speed. That is why the speed of sound in a gas is not constant, but depends on the temperature.
So, if we want <u>the speed of sound in a gas to increase</u>, the<u> temperature</u> of that gas must <u>increase</u>, as well.
For example, the higher the air temperature, the greater the velocity of propagation. Experiments have shown that the speed of sound in air increases for every increase in temperature.
Therefore:
<h2>The speed of sound will be faster than in December</h2>
