Answer:
the thermal energy generated in the loop = 
Explanation:
Given that;
The length of the copper wire L = 0.614 m
Radius of the loop r = 
r = 
r = 0.0977 m
However , the area of the loop is :
Change in the magnetic field is 
Then the induced emf e = 
e = 
e = 2.74 × 10⁻³ V
resistivity of the copper wire 
Ω m
diameter of the wire = 1.08 mm
radius of the wire = 0.54 mm = 0.54 × 10⁻³ m
Thus, the resistance of the wire R = 
R = 
R = 1.13× 10⁻² Ω
Finally, the thermal energy generated in the loop (i.e the power) = 
= 
=
Scientists use models to help explain an idea, visualize hypotheses, and closely examine something (such as an atom).
Answer:
464.69 m
Explanation:
First car
Second car
Distance = Speed × Time
Here, the time taken and the distance traveled will be the same
Equating the two equations
So, the first would have to move 
in order to overtake the second car.
Answer:4500 N
Explanation:
Given
mass of truck 
mass of car
as the car push the ground with a force of 4500 N so the force on the truck should also be 4500 N as they all the force is transmitted to push the truck
and their acceleration is
