The average velocity of Sandy is given by the total distance covered S divided by the total time taken t:
The total distance covered is
while the total time taken is 2 hours + half an hour (for the rest) + 1 hour and half, so
Therefore, the average velocity is
Answer:
The energy are traveled through the sun in two ways that are:
- By the radiation
- By the convection
As, the energy are first traveled outward from the core of the sun and then it get entered in the zone of the radiation and this zone is known as radiative zone in the surface of the sun.In the radiation process some amount of the hydrogen particle are combined and then releases the energy. And the convection is the process of conversion of one form of energy to another form.
ANSWER IS A)
THE SPEED IS 25 M/S FOR BOTH PEOPLE
1kg = 1000000000 micrograms
I hope it helps you ;)
Answer:
Explanation:
Effort x effort distance = load x resistance distance
effort distance = 8 m ,
load = 2000N
resistance distance = 1/2 m = 0.5 m
Putting the values in the equation above
effort x 8m = 2000N x .5
effort = 2000 x 0.5 / 8
= 125 N
force required = 125 N .
