An Object is moving due south at 16 m/s, when a force accelerates it at 4m/s in a southerly direction. How long will it take for

the object to reach a velocity of 48 m/s south. Please help me out.

Answer:

Time taken to accelerate to 48 m/s =  8 seconds

Explanation:

Initially the object is moving south at = 16 m/s

So, initial velocity of the object = 16 m/s

Acceleration caused by the force = 4 m/s^2

Final velocity towards south = 48 m/s

Using equation of motions:

v_f=v_i+at

where

v_f\rightarrow final velocity

v_i\rightarrow initial velocity

a\rightarrow acceleration

t\rightarrow time

Plugging in values.

48=16+(4)t

48=16+4t

Subtracting both sides by 16

48-16=16+4t-16

32=4t

Dividing both side by 4.

\frac{32}{4}=\frac{4t}{4}

8=t

∴ t=8

Time taken to accelerate to 48 m/s =  8 seconds

What can increase the peak emf in an ac generator without changing the frequency?
STatiana [176]

Explanation:

The peak emf in an AC generator is given by :

\epsilon=NAB\omega

Here,

N is number of turns in the generator

A is area of the coils

B is magnetic field

\omega is angular frequency

It is clear that the peak emf in an ac generator depends on :

  • The number of turns in the generator
  • Area of coils
  • Magnetic field
