The energy of a substance is defined as the capacity to do work.The energy may be possessed by the body in various forms.It may be kinetic,potential,magnetic.electric etc.
a- The energy can be transformed from one form to another form.It is called energy conversion.
c-The power defined as the consumption of energy per unit time.
Here E is the energy and W is the work done,t is the time.
d-The S.I unit of energy is Joule[J].
Hence the correct answer to the question is b. the ability to do work
Answer:
Explanation:
A number can be written in the form of :
Where
m is the real number
n is any integer
In this case, the average distance from the Sun to the Earth is given,
d = 150000000000 meters
There are 10 zeroes in this number. We need to write this number in scientific notation. It is given by :
So, the average distance from the Sun to the Earth is . Hence, this is the required solution.
Answer:
D. It can be Cyclic
Explanation:
Science has all different kinds of alike processes.
The scientific method is a generally and usually a Cyclical Process.
The magnitude of displacement =
the distance between start-point and end-point,
regardless of the route followed along the way.
Any motion that ends up where it started has zero displacement.
An object on a circular path starts over at zero displacement every time
it completes a full revolution. So does a race-car on a track.
