The body will take 20 seconds to cover a distance of 1000 m i.e. 1 km
You really can't tell.
Power = I^2 × R = V^2 / R ( unit in Watt)
For P = I^2 × R
Where we have P directly proportional to R, increase in Power leads to increase in R
So if we have 100 will have higher resistance
For P = V^2/R
Power is inversely proportional to resistance.
So increase in Power leads to decrease in resistance.
60 watt will have a higher resistance.
Answer:
<h2><u><em>
Plants use Nitrogen</em></u></h2>
Explanation:
<h3><em>They use it for nutrients</em></h3>
Angle made by the light ray with the surface of mirror is given as
degree
now as we know as per law of reflection that
angle of incidence = angle of reflection
So here we can say that
now the total angle that reflected ray will rotate with respect to incident ray is known as angle of deviation
so here reflected light will deviate by total angle of 40 degree fron its incident ray.
Answer:
Explanation:
Sine the plane is horizontal , effect of gravity on horizontal motion will be nil.
Since no friction is acting on it , no horizontal force is acting on it. Since no vertical ,no horizontal force is acting on it , it will have uniform motion ,ie its velocity will remain unchanged during its motion , no matter how long the path is.
So , velocity along the path will remain unchanged.
