Answer:

9.67\times 10^4 J

Explanation:

We are given that

Current=I=1.75 A

Resistance =R=55.4 ohm

Time=t=9.5 min=9.5\times 60=570 s

1 min=60 s

We have to find the heat generated by the resistor.

We know that

Heat=E=I^2Rt

Using the formula

Heat,E=(1.75)^2\times 55.4\times 570=9.67\times 10^{4} J

Hence, the heat generated by the resistor =9.67\times 10^4 J

A rocket initially at rest acceleration at a rate of 99.0meter/second^2. Calculate the distance covered by the rocket if it atta
Helga [31]

Distance traveled by the rocket= 1002 m

Explanation:

initial velocity= Vi=0

final velocity= V=445 m/s

time=4.5 s

Acceleration=a=99 m/s²

using kinematic equation

h= Vi t + 1/2 at²

h= 0(4.5) + 1/2 (99) (4.5)²

h=1002 m

Thus the distance traveled by the rocket= 1002 m
