Fluids always transfer heat by convection. So, your answer is B. That's how a oven works actually!
To solve this problem, it is necessary to apply the concepts related to force described in Newton's second law, so that
F = ma
Where,
m = mass
a = Acceleration (Gravitational acceleration when there is action over the object of the earth)
Torque, as we know, is the force applied at a certain distance, that is,

Where
F= Force
d = Distance
Our values are given as,



Since the system is in equilibrium the difference of the torques is the result of the total Torque applied, that is to say






Therefore the magnitude of the frictional torque at the axle of the pulley if the system remains at rest when the balls are released is 
Answer:
occurs when path-length difference is:
Δr=mlambda and m=0,1,2,3...
Explanation:
I think thats the answer.
The sound waves travel through the sea which creates movement which can be felt all the way in Italy in the sea- like a domino effect
Answer:
quasars are massive celestrial bodies that are far or remotely placed emitting large energy radiations.
parallax is the best way of determining distances between astronomical bodies and parallaxes of stars are measured relative to a quasar to minimise the measurement error. each observations is stimulated with the basic angle variations leading to minimum uncertainty in the results as the assumptions in the measurements are as minimal as possible.
