Let the rescue boat starts at an angle theta with the North
now its velocity towards East is given as
now in some time "t" it will catch the boy
so we will have
also we have
now we have
by solving above we got
Answer:
It is displaced.
Explanation:
As the coaster travels. The kinetic and potential energy shifts up and down. But when it shifts, some of the energy is displaced and lost.
B). Some elements found in nature exist as molecules.
That is, their atoms travel around in bound pairs.
Examples are Hydrogen, Oxygen, and Nitrogen.
A). No. Without atoms, you can't make a molecule.
C). No. A compound is a chemical combination of two or more elements.
D). No. An atom is the smallest unit of ONE single element.
Time , Work, Horsepower
Explanation:
In General, Power is defined as rate of doing work in physics.
1.) By work and Time, we can calculate power as follows,
Power = Work done per unit Time
= Work done / time
2.) From Horsepower we can directly get the power.
Horsepower (hp) is a unit to measure the power, or the rate at which work is done, usually in the output of engines or motors. There are many types of horsepower. Two common ways of defining horsepower is being used today are the mechanical horsepower (or imperial horsepower), which is about 745.7 watts, and the metric horsepower, which is approximately 735.5 watts.
