<h2>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:

Answer:
The magnetic field strength required to hold anti-protons, moving at 5.70 ✕ 10⁷ m/s in a circular path of 3.20 m in radius is 0.186 T.
Explanation:
To solve the question we note that the magnetic force on a moving charge is given by
F = q·v·B
Where
q = Charge
v = Velocity of the charge =5.70 ✕ 10⁷ m/s
B = Magnetic field
Based on Newton's second law,
Force = Mass, m × Acceleration, a = m × a
Where:
a = Acceleration
m = Mass of anti-proton = Mass of proton = 1.6726219 × 10⁻²⁷ kg
We note that for circular motion, acceleration a is given by
.
Where:
r = Radius = 3.20 m
Therefore, for the circular motion, force, F =
Equating the magnetic force equation to the circular force equation, we have
= q·v·B So that, we find B by making the subject of the formula as follows
. Which gives
= 0.186 T
The magnetic field strength is
B = 0.186 T
