<h2>Answer:</h2>
The speed of atoms depends upon:
- Temperature: Speed of atom is directly proportional to the temperature of atoms.
- Pressure : It is also directly proportional to the speed of an atom.
- Volume of gas : As the volume of gas increases, collision between atoms increases with increasing the speed of atom
- Number of atoms surrounding: More number of atoms leads to more collisions, increasing speed of atoms.
Hey there mate :)
Even if two persons are given the same work load, the speed of the work done gets different by the energy of those persons.
No one is sure that he/she can complete the work within the time. He may or may not.
Also, the physical characteristics makes the work different. If one person has so much power to work all day, the other person may not have.
Therefore, <em>even if two persons do the same amount of work , they may have different power</em><em>.</em>
<u>Explanation:</u>
Velocity of B₁ = 4.3m/s
Velocity of B₂ = -4.3m/s
For perfectly elastic collision:, momentum is conserved
where,
m₁ = mass of Ball 1
m₂ = mass of Ball 2
v₁ = initial velocity of Ball 1
v₂ = initial velocity of ball 2
v'₁ = final velocity of ball 1
v'₂ = final velocity of ball 2
The final velocity of the balls after head on elastic collision would be
Substituting the velocities in the equation
If the masses of the ball is known then substitute the value in the above equation to get the final velocity of the ball.
Answer:
From what I see, it's saying that every minute, the ant can move 30 meters. So how many meter would it move in 45 minutes?
30 meters = 1 min
x meters = 45 min
1 min x 45 = 45 min
30 meters x 45 = 1,350 meters
So, I believe the answer would be 1,350 meters.
hope this helps. :>
Don’t mind this i just need to answer under something because i just signed up !
