Answer:
If she has a magnifying glass in her tool box then just retrace your steps.
Answer:When you place like poles of two magnets near each other (north to north or south to south), they will repel each other
Explanation:
Every magnet has both a north and a south pole. When you place the north pole of one magnet near the south pole of another magnet, they are attracted to one another. When you place like poles of two magnets near each other (north to north or south to south), they will repel each other.
Answer:
Turns ratio=108, Pin= 110.5 W, Current ratting= 920mA
Explanation:
Vp=120 V(rms)
Vs=13,000 V (rms)
Is = 8.50*10^-3 V(rms)
a.
secondary to primary turn ration:
Ns/Np=Vs/Vp
=
=
= 108
b.
Is=8.50 mA (rms)
As Vs= 13,000V (rms)
For ideal transformer
Pin=Pout______(1)
Pout= Is*Vs (put in equ 1)
Pi=Is*Vs
Pi=(8.50*10^-3)*(13,000) W
Pi=110.5 W
Power supplied will be 110.5 W.
c.
We have to find the current passing through primary circuit to find current rating of fuse in primary circuit.
For ideal case
Ip*Vp= Is*Vs
Ip=
Ip= (13000*8.5*10^-3)/120
Ip=920 mA
In primary circuit fuse current rating will be 920 mA.
Answer:
Newtons.
Explanation:
Force is given by the multiplication of mass and acceleration.
Mathematically, Force is;
Where;
F represents force measured in Newton.
m represents the mass of an object measured in kilograms.
a represents acceleration measured in meter per seconds square.
Newtons is a measurement we use to determine the amount of force used to move an object by a simple machine. It is the International System of Units (SI) used to measure force and has a symbol of N.
Basically, it was named after Sir Isaac Newton based on his fundamental works in the field of mechanics (motions).
