Answer:
2.62 m
Explanation:
Let the small child sit at a distance x from the pivot.
The distance of big child from the pivot is 4 - x .
By using the concept of moments.
Clockwise moments = anticlockwise moments
27 x = 51 ( 4 - x )
27 x = 204 - 51 x
78 x = 204
x = 2.62 m
Answer:
Biomedical engineering
Explanation:
this is because plant sees are important
Position displacement velocity acceleration are vectors and the rest are scalars
Answer:
No
Explanation:
Loudness describes how people perceive sound (see loudness). ... If people could hear equally well at all frequencies, the contour lines would be flat because the same measured sound intensity would be perceived to be equally loud regardless of the sound frequency. In fact, people do not hear as well at low frequencies.
Answer:
9.9 m/s
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration due to gravity = 9.81 m/s²
If the body has started from rest then the initial velocity is 0. In order to find the velocity just before hitting the water then the distance at which the downward motion stops is irrelevant.
Hence, the speed of the diver just before striking the water is 9.9 m/s
