The answer will be maximum.
Answer:
v_average =0
Explanation:
In kinematics the average speed defined with the distance interval traveled in a given time interval
V = Δx /Δt
in this case the tennis ball travels a distance h to the highest point and a distance h from the highest point to the floor, so the distance you travel zero
Dy = h -h = 0
therefore the average speed should be zero
v_average =0
Concrete is also used as beam material, and is cheaper. However, concrete is comparatively not that strong to withstand the high tensile forces acting on the beams
Answer:
The length of the pipe A is = 0.4763 m & the length of the pipe B is 0.357 m
Explanation:
Fundamental frequency = 360 Hz
Velocity = 343
(a). Length of the pipe is given by
Put all the values in above equation we get
= 0.4763 m
(b). Given that
The third harmonic of organ pipe B = the second harmonic of pipe A
Thus
Put all the values in above formula we get
0.357 m
Therefore the length of the pipe A is = 0.4763 m & the length of the pipe B is 0.357 m
1) v=u+gt = -5 +10*2=15 m/s
2) r=ut+gt^2/2=-5*2+10*2^2/2=-10+20=10m
3) r of heli= vt =5*2=10m
So 10m by bag from answer number 2 plus additional 10m by helicopter equals 20m
