Your car is performing a transformation of energy of:
Chemical energy to Mechanical energy
The chemical is the gasoline which is then converted to fire as the car runs thus creating the movement of the car which is mechanical energy.
Right answer is option b that is the inner planet may havebeen larger and more gaseous.
Answer:
Correct option is D.
Explanation:
The size may change due to the distance from the mirror
I am 100% Sure about this answer
Answer:
a) 73.2N
b) 66.6N
c) 20.28N
Explanation:
F= mg=7.5×9.8=73.5N
Force parallel to the plane Fp= 73.5sin25= 31.06N
b) Fv= 73.5 cos25= 66.6N
c) Ff= u×Fv= 0.312×66.6=20.28N
a) Normal ForceFn= F/(cos25) - Fp - Ff = ma
1.1F -31.06-20.28=7.5×3.82
1.1F -51.84=28.65
1.1F= 28.65+51.84
F= 80.49/1.1
F= 73.2N
F would 0.825 because the coefficient of kinetic friction between the block and the plane surface uk of 0.35
