From the calculation, the speed of sound at 10 K is 63.5 m/s.
<h3>What is the speed of sound?</h3>
We know that the speed of sound is directly proportional to the temperature of the body thus we can write;
V1/V2 = √T1/T2
Then;
T1 = 0 degrees or 273 K
T2 = 10 K
V1 = 330 m/s
V2 = ?
330/T2 = √273/10
330/T2 = 5.2
330 = 5.2T2
V2 = 330/5.2
V2 = 63.5 m/s

Answer:
right is the correct answer to the given question .
Explanation:
In this question figure is missing
The main objective right-hand rule to decide the position of the magnetic force on the positive force acting, either the position of the thumb of a right hand with in position of v, the fingers throughout the position of B1, and a right angles throughout the position of F1 to the hand positions.
So 
- So from the magnetic right hand rule the direction of the magnetic field in front of a wire is right .
- All the others options are incorrect because they do not give the direction of the magnetic field in front of a wire is right .
Answer:
I am fairly certain the answer is 2m/s^2
Explanation:
Any point in the wire has 1.12 x
. electrons flow per second.
<h3>What causes a current in a wire?</h3>
- Electric current in a wire, where electrons serve as the charge carriers, is a measurement of the amount of charge that moves through any point of the wire in a given amount of time.
- A free electron is drawn to a proton to become neutral if an electron is added to the wire.
- Lack of electrons can result from pushing electrons out of their orbits.
- Electric current is the name given to the constantly moving electrons in wire.
The current is the quantity of charge Q flowing through a certain point of the wire in a time interval of
.
I =
.
by using this relationship
I=1.80 A, we can find the charge passing any point in the wire in 1 second:
Electric Charge, Q = 1.80 C.
To find how many electrons corresponds to this charge, we should divide this value by the charge of a single electron
charge of the electron = 1.6 x
C.
No. of Electrons = Q/q =
= 1.12 x

Answer:
Explanation:
An object’s mass will remain constant throughout the universe, but its WEIGHT can change from planet to planet.
If you increase the mass of a planet, what happens to its gravity?
If the radius does not change, Then its gravity increases.
If the gravity on a planet decreases, what happens to the weight of an object on that planet? Weight decreases.
