Answer:
D is the answer
Explanation:
6.45×7.44= 47.98800
Which if we round of we get 48m
Answer:
2 and 3
Explanation:
because that's how kinetic and potential energy work
Answer:
F = m X a
Therefore ,
Force required = 50 X 30 = 1500 newton
Answer:
0.005 V
Explanation:
We are given that
Initial circumference of circular loop=C=165 cm
Rate of circumference,
Magnetic field,B=0.5 T
We have to find the induced emf at time t=9 s
We know that induced amf,E=
Area of circular coil,A=

Circumference of circular coil,C=



Radius of coil at time t=9 s


E=
Magnitude of induced emf=0.005 V
its the 3rd one kinetic energy increases as speed increases
