Answer:
the maximum possible coefficient performance is 13.7
Explanation:
inside temperature, 
= 61 F = 289.26 K
outside temperature, 
= 99 F = 310.37 K
coefficient of performance, COP (real) = 3.2
according to Carnot's theorem, the coefficient of performance is
= 
where
is cold temperature
is hot temperature
thus,
= 
= 13.7
Answer:
A cloud can discharge as much as 20 coulombs in a lightning bolt.

Answer: Both are Brittle
Explanation:
Metals are lustrous, malleable and ductile. Metals are good conductors of heat and electricity.
Non-metals are poor conductors of heat and electricity. Non-metals are brittle and non-lustrous elements.
Elements which have properties between metals and non-metals are known as metalloids.
Some mettaloids are lustrous and conductors of electricity. One property that these elements share with non-metals is that these are brittle i.e. they can easily break.
Answer:
The magnitude of force is 
Solution:
As per the question:
The strength of Electric field due west at a certain point, 
Charge, Q = - 6 C
Now, the force acting on the charge Q in the electric field is given by:
Here, the negative sign indicates that the force acting is opposite in direction.
