Answer:
The avarage power of the body is 96.898 watts.
Explanation:
We must notice that given definition of power implies a constant consumption of energy, so that we should assume that energy consumption is constant. A Calorie is equal to 4186 joules. If we know that 
and 
, the power of body, measured in watts, is:
The avarage power of the body is 96.898 watts.
Answer:
0
Explanation:
Defining velocity :
Velocity is a vector which is the ratio of a person's total displacement with time.
Displacement, in simple terms refers to the distance between an individual's initial position to his final position.
Man's initial position = House
After all his navigation and points covered irrespective of the distance ;
Final position = House
Hence, we can conclude that the man's Displacement is ;
Final position - Initial position = 0
Hence,
Velocity = Displacement / time taken
Velocity = 0 / 3
Velocity = 0
Answer:
800
Explanation:
Focal length of telescope, F = 200cm
Focal length of eyepiece, f = 0.25
The magnifying power of a telescope is given as the ratio of the focal length of the objective of the telescope to the focal length of the lens. Mathematically:
M = F/f
Therefore, when F = 200cm and f = 0.25cm:
M = 200/0.25
M = 800
Answer:
Pitch. The sound an article makes changes relying upon how quick it is vibrating. At the point when an item vibrates rapidly, sharp sounds are heard. Low-pitched sounds come from things that vibrate all the more gradually.
