The force that a moving object has which is dependent on the speed and weight of the object is Momentum
The product of an object's mass and velocity is known as its linear momentum, translational momentum, or simply momentum in Newtonian physics. It has both a magnitude and a direction, making it a vector quantity. When an object has a mass of m and a speed of v, its momentum, p, is equal to ma. Its SI Unit is Kgm/s
The speed of a body is defined as the rate at which the position of a body changes per unit of time. Its SI unit is m/s.
Weight is defined as the amount of force, in general, it's the gravitational force, which acts on the body. It is measured in Kilogram (kg).

Components connected in series are connected along a single path, so the same current flows through all of the components. If the light bulbs are connected in parallel, the currents through the light bulbs combine to form the current in the battery, while the voltage drop is across each bulb and they all glow.
There are two main types of solar energy technologies photovoltaic (pv) And concentrating solar thermal power
Answer:
Explanation:
18 kW = 18000 J /s
60% of 18kW = 10800 J/s
Latent heat of evaporation of water
= 2260 x 10³ J / kg
kg of water being evaporated per second
= 10800 / 2260 x 10³ kg /s
= 4.7787 x 10⁻³ kg / s
= 4.78 gm / s .
