Answer:
The internal combustion engine in the car converts the potential chemical energy in gasoline and oxygen into thermal energy which is transformed into the mechanical energy that accelerates the vehicle (increasing its kinetic energy) by causing the pressure and performing the work on the pistons.
Two resistors of resistance 19 ohm each are connected in series.
In series combination, equivalent resistance = 19+19 = 38 ohm
Potential difference = 10 V
V/I = R
I ( current ) = V/R = 10 V / 38 ohm = 0.26 ampere
Answer:280.33 m
Explanation:
Given
motorcycle starts from rest
initial acceleration
distance traveled =120 m
velocity gain during this time, let say v
after it starts decelerating with 1.5 m/s^2 [/tex]
final velocity()=12 m/s
12=25+(-1.5)t
t=8.667 s
distance traveled during this time
Therefore total displacement=
Answer:
In Celsius:
Explanation:
The formula we are going to use is:
Where:
ε is the emissivity
σ is the Stefan constant
is the final temperature of surrounding surfaces
is the required temperature
is the are of surrounding surface
Calculating The area:
σ=
ε =0.95
=55+273
=328 K
=100 W
In Celsius:
