Speed = 52/1.57576= 33 m/s
Explanation:
Distance = speed * time
Given , the distance traveled by the baseball = 52 m
Speed of sound in air = 330 m/s
Total time = 1.73333 s .
Total time for the student to hear the sound of the gong is the sum of the time take for the baseball to reach the gong and the time taken by the sound to travel back.
Distance traveled by the sound is 52 m and the speed is 330 m/s
So time taken by the sound to travel back = distance traveled / the speed
=> time = 52/330 s = 0.15757 s
Time taken by the base ball to reach the gong is the total time - the time taken by the sound
=> time taken by base ball = 1.73333 - 0.15757 = 1.57576s
Speed of the base ball to reach the gong = distance / time
Speed = 52/1.57576= 33 m/s
Avogadros law is applied when temperature and pressure remain constant, and details the direct relationship between moles and volume in this circumstance
Explanation:
You are given the initial velocity, the displacement, and the acceleration. You're looking for the final velocity. So you use the equation:
v² = v₀² + 2aΔy
When you solve for v, you take the square root. Your calculator will return a positive answer, but there are actually two possible answers: positive and negative.
v = ±√(v₀² + 2aΔy)
You must use the physical context of the problem. If we take up to be the positive direction, then v must be negative, since the projectile is moving down.
The answer is solar flare ; an eruption of high - energy radiation from the sun.
Average speed = total distance/total time.
