Answer:1.81
(a) Explanation:the turn ratio= input voltage÷output voltage.
400÷220=1.81.
Don't know how to solve b part...
It's used to measure the mass or weight of an object
Answer:
Explanation:
Given
mass of bus along with travelers travelling in North direction is
speed of bus towards North
mass of bus travelling in South direction is
speed of bus
mass of each Passenger in south moving bus
Momentum of North moving bus
Momentum with south moving bus
For total momentum to be towards south
should be greater than 0
thus for least value of n
Answer:
Explanation:
Given
diameter of spacecraft
radius
Force of gravity =mg
where m =mass of object
g=acceleration due to gravity on earth
Suppose v is the speed at which spacecraft is rotating so a net centripetal acceleration is acting on spacecraft which is given by
Answer:
The principle of a potentiometer is that the potential dropped across a segment of a wire of uniform cross-section carrying a constant current is directly proportional to its length. The potentiometer is a simple device used to measure the electrical potentials (or compare the e.m.f of a cell).
