Explanation:
Answer:
False
Explanation:
When we open the gate of refrigerator then the temperature of kitchen get increase.
But we think how it is possible that temperature of kitchen get increases.Actually the heat rejecting coil(condenser) is also present inside the room that is why it reject more heat as compare to heat absorbed by evaporator coil.This is the reason to increases the temperature of kitchen.
If heat rejecting coil put outside the kitchen then it will produces cooling effect even door of refrigerator open.This concept use in air conditioning.
Answer:
Where is the picture? I'll try to help as much as I can but I can't promise anything.
Answer:
Part 1) Speed at s = 420 meters =12.26 m/s
Part 2) Time required to cover the distance = 26 seconds
Explanation:
This problem can be solved using third equation of kinematics as follows
where
'v' is the final velocity
'u' is the initial velocity
'a' is the acceleration of the car
's' is the distance covered between change in velocities
Now during the time at which the car moves it cover's a distance of 420 m-100 m=320 meters
Thus applying values in the above equation we get
The time to reach this velocity can be found using first equation of kinematics as
