Using Kepler's 3rd law which is: T² = 4π²r³ / GM
Solved for r :
r = [GMT² / 4π²]⅓
Where G is the universal gravitational constant,M is the mass of the sun,T is the asteroid's period in seconds, andr is the radius of the orbit.
Change 5.00 years to seconds :
5.00years = 5.00years(365days/year)(24.0hours/day)(6... = 1.58 x 10^8s
The radius of the orbit then is computed:
r = [(6.67 x 10^-11N∙m²/kg²)(1.99 x 10^30kg)(1.58 x 10^8s)² / 4π²]⅓ = 4.38 x 10^11m
Answer:
35%
Explanation:
Given data
Amount of energy transferred (Input) = 270J
Amount of energy converted to sound (Output)= 94.5J
Efficiency = output/input*100
Efficiency= 94.5/270*100
Efficiency=0.35*100
Efficiency=35%
Hence the efficiency is 35%

What is newton's second law of motion?Also give example.

<u>Definition</u>:-
Newton's Second Law of motion states that the rate of change of momentum of an object is proportional to the applied unbalanced force in the direction of the force. ie., <u>F=ma</u>.
<u>Examples:-</u>
- When you are kicking a ball, you are increasing the speed by applying force to it. Therefore,it accelerates.
- If you use the same force to push a truck and push a car, the car will have more acceleration than the truck.
Derivation:-
For a body of mass 'm' , whose velocity changes from u to v in time t, when Force 'F' is applied.
=>Force∝Change in momentum/Time
=>F∝mv-mu/t
=>F∝m(v-u)/t
=>F∝ma
=>F=kma(a=v-u/t)
=>F=ma(Since k=constant=1)
