Answer:
I think my friend got it all wrong, as coolness can not be transferred but heat was actually transferred between my hand and the glass windows
Explanation:
In thermodynamics, coolness can not be transferred, only heat can be transferred
Here is how the mechanism of why i felt cold works, my body gave out heat, hence there was heat transfer from a region of high to a low heat region, equilibrium was reached and I started feeling the coolness in my hands.
Answer:
An object which moves in the negative direction has a negative velocity. If the object is speeding up then its acceleration vector is directed in the same direction as its motion (in this case, a negative acceleration).
Explanation:
Answer:
Sunlight and almost every other form of natural and artificial illumination produces light waves whose electric field vectors vibrate in all planes that are perpendicular with respect to the direction of propagation.
Answer:
Explanation:
Given that
B(y, t) = k y ³t²
To find the total flux over the loop we have to integrate over the loop
Given that loop is square,so
B(y, t) = k y ³t²
We know that emf given as
So
Answer:
A) True. The droplets will move in parabolic arcs.
Explanation:
When the dog shakes the drops that leave the fur they leave with a speed and an angle; These are now subject to the out of gravity that accelerates them in the vertical axis and has no outside the horizontal axis, so they must describe a parabolic movement.
Pair to describe a central force that changes its speed, but this force does not exist once they leave the dog
Let's check the answers
A) True. You agree with the analysis
B) False. There is an outside on the axis and therefore the line is deviating
C) False. There is no radial force that creates this movement
