D.
Have a longer revolution time since they definitely do not get warmer, They do not have fewer moons (Jupiter has about 100 and earth has 1) they are not smaller in diameter (Earth v Jupiter)
Answer with Explanation:
We are given that
Initial velocity,u=4.5 m/s
Time=t =0.5 s
Final velocity=v=0m/s
We have to find the deceleration and estimate the force exerted by wall on you.
We know that
Acceleration=
Using the formula
Acceleration=
deceleration=a=
We know that
Force =ma
Using the formula and suppose mass of my body=m=40 kg
The force exerted by wall on you
Force=
The answer to your question is C. <span> the Sun's strong gravitational field . This is correct because i took the test :D</span>
Answer:
900 W.
Explanation:
Given that
Electric heater 1500 W
We know that power P given as
P= V I
So the total power of 120 V and 20 A circuit
P = 120 x 20
P= 2400 W
So the power new load P'
P'= Total system power(P)- Electric heater load
P ' = 2400 - 1500
P'= 900 W
So the answer is 900 W.
