Answer:
Mechanical advantage is a measure of the force amplification achieved by using a tool, mechanical device or machine system.
Explanation:
Answer:
Distance covered to top of the hill was : 1.755 km
Explanation:
Initial velocity = 35 km/hr
Acceleration = 2.0 km/hr²
Time taken to accelerate = 3 minutes = 3/60 hours = 1/20 hours
Formula for acceleration : a = Δv /t
v-u/t ---where u is initial velocity , v is final velocity and t is time taken for acceleration
v- 35 / 0.05 = 2
v = 35.10 km/h
Formula for distance is product of speed and time
Distance covered = 35.10 * 0.05 = 1.755 km
Wavelength is defined as distance between two troughs or two crests !!
so in this wavelength is 4 metres !!
The answer would be B: The ground exerts an equal force on the golf ball.
