A Carnot air conditioner takes energy from the thermal energy of a room at 61°F and transfers it as heat to the outdoors, which
1 answer:
Answer:
<em>14.07 units of joules is removed for each joules of electricity used</em>
Explanation:
The heated room temperature = 61 °F
The outside temperature = 98 °F
For conversion from fahrenheit to kelvin we use the equation
(32°F − 32) × 5/9 + 273.15
= 289.26
= 309.82
For air conditioning,
COP =
COP = = 14.07
This means that <em>14.07 units of joules is removed for each joules of electricity used</em>

Answer:
Explanation:
According to the free-body diagram of the system, we have:
So, we can solve for T from (1):
Replacing (3) in (2):
The electric force () is given by the Coulomb's law. Recall that the charge q is the same in both spheres:
According to pythagoras theorem, the distance of separation (r) of the spheres are given by:
Finally, we replace (5) in (4) and solving for q:
Answer:
t = 3 seconds
Explanation:
Given that,
Initial speed, u = 30 m/s
Final speed, v = 0
It slides 45 m to rest.it take the box to come to rest
We need to find how long it take the box to come to rest.
Let a be the acceleration and t is time.
Now finding time.
So, the required time is 3 seconds.
