speed of the participants is given as
now the kinetic energy of the participant is given as
As we know that
1 calorie = 4.2 J
so here 230 Calorie is provided by 1 bar
bar required is
Explanation:
If the two charges are point charges - i.e., they don't have a size - the force between these charges depends on the
• Magnitude if each charge, q1 and q2
• Sign of each charge (+ or -)
• Distance between the charges, r
This is essentially Coulomb’s Law:
FE = (kq1q2)/r2
For collections of charges, you need to find the electric field E, and then use this fields to find a force on a small test charge q in the field. The test charge is always small to help you map the electric field, but not disturb it.
CONDENSATION is the process by which water vapor (gas) in the atmosphere turns into water (liquid state). It is the opposite of EVAPORATION.Cool temperatures are essential for condensation to happen, because as long as the temperature in the atmosphere is high, it can hold the water vapor and delay condensation. So the temperature in condensation rises.
<span>Molecules at higher temperatures have more energy,
thus they can vibrate faster. Since the molecules vibrate faster, sound
waves can travel more quickly. The speed of sound in room temperature
air is 346 meters per second. so that would be answer A</span>
What is the multiple choice???
