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
Answer:
47.515 cm²
In meter square= 4.7515 *10^-3 m²
Explanation:
The radius of a circle = 5.5 cm
In meter= 5.5*0.01
= 0.055 m
the circumference= 34.56 cm
in meters = 34.56 cm*0.01
= 0.3456 meters
the area= 95.03 cm²
in square meters =95.03*(0.01)²
in square meters= 9.503*10^-3 m²
. area under the curve at the right
= Area of semi circle
= Area of circle/2
= 95.03 /2
= 47.515 cm²
In meter square= 4.7515 *10^-3 m²
Answer:
Lateral inversion is a phenomenon in which left appears to be right and vice versa. It is due to direction that light follows when it strikes a reflecting surface, generally a mirror.
Satellite (moon) revolve around the planet
But planet revolve around the sun.
Ganymede is a satellite(moon) which revolve around the planet jupiter. So, it is considered as moon not planet.
