G is actually the universal gravitational constant.
6.674×10−11 m3⋅kg−1⋅s−2
This proportional to the product of the two objects masses and the inverse square of their distance.
This different from g which the local gravitational constant.
Answer:
can be there and we will make sure to get a me to do it and get it done by then and I'll let u get back with you are you are going for the best way of doing it for a while now that I am a.
Answer:
See below ~
Explanation:
Part (a) :
We can say a body is in uniform acceleration if the acceleration of the object remains constant with respect to time throughout its motion.
Part (b) :
We can say a body is non-uniform acceleration if the acceleration of the body varies with respect to time throughout its motion.
Answer:
Because SI system has fundamental units of MKS System
Answer:
Increase in total energy will be equal to the increase in the internal energy i.e 
Joules
Explanation:
Given
Weight of sledge hammer 
kilogram
Speed of sledge hammer 
meter per second
Kinetic energy is equal to half the product of mass and velocity square
Substituting the value of mass and velocity, we get -
It is given that one fourth of the energy is converted into internal energy
One fourth of kinetic energy is equal to
Increase in total energy will be equal to the increase in the internal energy i.e Joules
