Why do yachts sail west to east when competing in around the world yacht races?
well the air velcity is much greater when travelling in the direction of king kong in the jungle therefore prople play Pokemon
An object is moving with constant velcity and it is not accelering. Can it have any forces acting on it?
Yes, that's possible, as long as the vector sum of all such forces is zero.
What point is the orbital velcity of earth the greatest?
At perihelion, when the Earth is closest to the Sun, about January 4 each year.
At what velcity does light travel trought a gas?
It varies, depending on the gas, and on the properties of the gas (mainly temperature and pressure). But under "normal" circumstances, the speed of light in a gas is almost the same as the speed of light in a vacuum.
What symbol represents the speed of light?
speed does not have any symbol if you are talking about velcity then v,acceleration-a s is used as a symbol but it is generally for height.
When a velcity of a body is increased 5times what is the change in its kinetic energy?
The kinetic energy is proportional to the square of the speed. That means that if you increase the speed by a factor of 5, the kinetic energy increases by a factor of (5 squared).This applies to non-relativistic speeds; if you approach the speed of light, a different formula must be used.
Would you Give me a question and answer about acceleration?
Question:A car starts from rest and accelerates uniformly. It acquires a velocity of 72 km/hr in 10 seconds. What is its acceleration?Answer:Since the car is starting fom rest, its initial velcity (u) = 0Final velocity (v) = 72 km/hr =20 m/sTime taken for change of velocity (t) = 10 secondsAcceleration, a = (v-u)/t = (20-0)/10 = 20/10 = 2 m/s2
