Answer:
Explanation:
We are given that
Current=I=1.75 A
Resistance =R=55.4 ohm
Time=t=9.5 min=
1 min=60 s
We have to find the heat generated by the resistor.
We know that
Heat=E=
Using the formula
Heat,
Hence, the heat generated by the resistor =

Answer:
The displacement is
The distance is
Explanation:
From the question we are told that
The height from which the ball is dropped is
The height attained at the first bounce is
The height attained at the second bounce is
The height attained at the third bounce is
Note : When calculating displacement we consider the direction of motion
Generally given that upward is positive the total displacement of the ball is mathematically represented as
Here the 0 show that there was no bounce back to the point where Billy released the ball
=>
Generally the distance covered by the ball is mathematically represented as
The 2 shows that the ball traveled the height two times
=>
