Release correct vygygyvybuhibin
Radius of circle of spiral path = 6 m
Time period = 5 s
So the total length of the path = 
time taken by bird to cover the distance = 5 s
so the speed of the bird = distance / time
so the tangential speed in horizontal direction = 7.54 m/s
vertical velocity by which it is rising upwards = 3 m/s
so the angle with the horizontal for net speed is given as
so velocity vector will make 21.7 degree with the horizontal
The answer is solar panels
Newton 3rd law:
F=ma
1600=85*a
1600/85=a
a=18.82 m/s^2
The correct answer is C.
Nuclear fusion is an energetically favorable process for lighter atoms.
The proportion of hydrogen which is converted to energy in nuclear fusion is 0.68 percent or 0.7 percent.
Nuclear fusion produces energy which is from matter and nuclear fusion produces matter from energy.
The nuclear energy which splits large atom into small ones and then gives out energy.
Some matter is being lost and being converted to energy by Einstein's Δm×C².
Nuclear energy fusion makes larger elements and takes smaller elements.
For fusion to occur then energy must be converted to mass.
