F = force applied to hold the weight of the bowling ball = weight of the bowling ball = 75 N
d = distance through which the bowling ball is moved horizontally = 10 meter
θ = angle between the force in vertically upward direction and displacement in horizontal direction = 90
W = work done on the bowling ball
work done on the bowling ball is given as
W = F d Cosθ
inserting the values
W = (75) (10) Cos90
W = (75) (10) (0)
W = 0 J
Answer:
how matter and energy interact
The average speed would simply be the ratio of distance
and time. That is:
average speed = distance / time
in km/hr
average speed = 406 km / 7 hr = 58 km / hr
in m/s
<span>average speed = (58 km / hr) * (1000 m / 1 km) * (1 hr /
3600 s) = 16.11 m/s</span>
If committees is an option it is the correct one.
Answer:
five characteristics: Wavelength, Amplitude, Time-Period, Frequency and Velocity or Speed
