Evaporation because the water from the pond will evaporate and transform into a field. To evaporate is when water molecules go up and there is no more water.
Answer:
<em>An object is said to be rated </em><em>1 Watt </em><em>when it performs a work worth </em><em>1 Joule </em><em>in </em><em>1 second.</em>
Explanation:
<em>We know that power is rate of doing work or Work done in a given period of time.</em>
<em>Power is simply given by the formula:</em>
<em>Power=(Work)/(Time)</em>
<em>The SI unit of Power, Work and Time are Watts, Joules and Seconds respectively.</em>
<em>Hence, 1 Watt=1 Joule/ 1 Second</em>

Answer:
W = 950J
Explanation:
From the problem we have these values:
F = [3x,4y]N
ΔX = 10m
ΔY = 20m
Answer:
The magnitude of the magnetic field is .
Explanation:
Given that,
Charge,
Speed of the charged particle,
The angle between the velocity of the charge and the field is 56°.
The magnitude of force,
We need to find the magnitude of the magnetic field. When a charged particle moves in the magnetic field, the magnetic force is experienced by it. The force is given by :
B is the magnetic field.
So, the magnitude of the magnetic field is . Hence, this is the required solution.
Answer:
≈147.86 (m.)
Explanation:
1) if the acceleration is a=(V-V₀)/t, where V₀ - initial velocity (25), V - final velocity (2), t - elapsed time, then
t=(V-V₀)/a=23/2.1 (sec.);
2) the required distance can be calculated according to the formula:
S=V₀t+0.5(at²), where V₀=25; t=23/2.1; a= -2.1;
3)
