Answer:
10 seconds
Explanation:
As it starts from rest, then u=0
and by III rd equation of motion:
Answer:
Explanation:
Given that
Intensity I
Radius of earth,R = 6370 Km
We know that surface area of earth, A
As we know that pressure due to intensity given as
V =Velocity of light
We know that force F
F = P .A
b)Gravitational force F
So F
Transverse wave, movement in which all focuses on a wave sway along ways at right edges to the course of the wave's development. Surface swells on water, seismic S (auxiliary) waves, and electromagnetic (e.g., radio and light) waves are instances of transverse waves. Waves come in two assortments.
Answer: Minimum speed needed by the Olympic champion at launch if he was traveling at 6.8 m/s at the top of the arc is 11.65 m/s.
Explanation:
Velocity is only in horizontal direction at the top most point which is similar to the velocity in the horizontal direction at the time of launch.
Now, according to the law of conservation of energy the formula used is as follows.
As speed at which the person is travelling was 6.8 m/s. Hence, the initial velocity will be calculated as follows.
Thus, we can conclude that minimum speed needed by the Olympic champion at launch if he was traveling at 6.8 m/s at the top of the arc is 11.65 m/s.
