If you neglect air resistance, then you can solve for the horizontal distance using the formula:
dx=vixt
Where:
dx = horizontal distance
vix = initial horizontal velocity
t = time in flight
Now you can see that you have all the given you need.
vix= 2km/h
t = 0.25 hours
We use hours because you need the units to be the same. So just plug that in your equation and you will have your answer:
dx = vixt
=(2km/h)(0.25h)
=0.5km
This means that the answer to your question is B.
yes that is true because climate is over a period of time
Answer: time t = 2 seconds
Explanation:
Given that
Power P = 50W
Energy E = 100J
How long did it take to move the box from the floor to the shelf ? This implies time taken.
Power is defined as the rate at which work is done. I.e
P = W.D/t
Where work done = energy
50 = 100/t
Make t the subject of formula
t = 100/50
t = 2 second
The force exerted by the laser beam on a completely absorbing target is .
The given parameters;
- <em>power of the laser light, P = 1050 W</em>
- <em>wavelength of the emitted light, λ = 10 μm </em>
The speed of the emitted laser light is given as;
v = 3 x 10⁸ m/s
The force exerted by the laser beam on a completely absorbing target is calculated as follows;
P = Fv
Thus, the force exerted by the laser beam on a completely absorbing target is .

When the system reaches 60° North latitude after moving away from the equator and passing directly over water, it will be at a point where most of its energy is lost.
The low pressure system will dissipate its energy as it propagates through the air and more energy will be lost due to the high content of water vapor in the air above the water.
