Answer:
100 m/s
Explanation:
SI units of distance and time are <em>meters</em> and <em>seconds</em>. km and hours are derived units. To express speed in SI units, it must be expressed as <em>meters per second</em>.
360 km/h = 100 m/s
_____
There are 3600 seconds in 1 hour, so 1 m/s = 3600 m/h = 3.6 km/h.
Explanation:
In washing machine, the electrical energy is converted in kinetic energy then the mechanical energy is converted into thermal (heat) energy.
Answer.
The road on the hills goes upward with the increasing length of the road.That's why we make a winding roads because it reduces the allover surface inclination in every portion of the road which is suitable for driving the vehicles.
Answer:
The velocity of the boy and the bicycle is 2.2 m/s.
Explanation:
We have,
Mass of child is 30 kg and the mass of bicycle is 20 kg. The combined momentum of the child and the bicycle is 110 kg-m/s.
It is required to find the velocity of the boy and the bicycle. The momentum of an object is given in terms of mass and its velocity. So,
M is combined mass of child and bicycle
So, the velocity of the boy and the bicycle is 2.2 m/s.
