The car's speed is 240km/4hr= 60km/hr.
There's not enough information given in the question to determine its velocity.
Answer:
The input force that you use on an inclined plane is the force with which you push or pull an object. The output force is the force that you would need to lift the object without the inclined plane. This force is equal to the weight of the object.
Explanation:
Define heat capacity of a substance:
- The heat capacity of a substance can be defined as the amount of heat required to change its temperature by one degree.
Write the S.I unit of heat capacity:
-,-
Answer:
If all these three charges are positive with a magnitude of each, the electric potential at the midpoint of segment would be approximately .
Explanation:
Convert the unit of the length of each side of this triangle to meters: .
Distance between the midpoint of and each of the three charges:
Let denote Coulomb's constant (.)
Electric potential due to the charge at : .
Electric potential due to the charge at : .
Electric potential due to the charge at : .
While forces are vectors, electric potentials are scalars. When more than one electric fields are superposed over one another, the resultant electric potential at some point would be the scalar sum of the electric potential at that position due to each of these fields.
Hence, the electric field at the midpoint of due to all these three charges would be:
.
Women generally have a lower centre of gravity than men, contributing to greater stability. Men generally have more muscle mass in their upper bodies,
