Answer:
<h3>4</h3>
Explanation:
VR = Velocity ratio = Distance moved by effort/Distance moved by load
Given:
Distance moved by effort = 20m
Distance moved by Load = 5m
VR = 20/5
VR = 4
Hence the velocity ratio of the car is 4
Answer:
The answer is A .
Explanation:
Ore is a rock that requires mining .
A. The amount of water. 50/50
Answer:
The velocity at the top of its path will be zero (0)
Explanation:
We can solve this problem or particular situation using the principle of energy conservation.
Which tells us that energy is transformed from kinetic energy to potential energy and vice versa. A reference point should be considered at which the potential energy is zero, and at this point the initial velocity of 40 [m/s] is printed to the ball.
The potential energy is determined by:
The kinetic energy is determined by:
This will be the maximum path but, its velocity at this point will be zero. Because now all the kinetic energy has been transformed in potential energy.
A maximum of four bonds can be used between two atoms.
<u>Explanation:</u>
Ionic bond is one of the strongest bond used in chemical reaction where the valence electrons are bonded and shared between the atoms. Sometimes four covalent bonds between two atoms might make them unstable as the bonds are formed in their outermost shell to make them to form or complete a total of 8 in their shell. For example carbon has 3 as maximum.
