Answer:
Magnetic field, B = 0.88 T
Explanation:
It is given that,
The dimension of rectangular surface is 2.80 cm by 3.15 cm. The area of rectangular surface is, 
Angle between the uniform magnetic field and the horizontal, 
Magnetic flux, 
Let B is the magnitude of magnetic field in which the rectangular surface is placed. It is given by :
is the angle between magnetic field and the area
Here, 
B = 0.88 T
So, the magnitude of magnetic field is 0.88 T. Hence, this is the required solution.
Answer:
I'm pretty sure it means like getting abs and working out your stomach.
Explanation:
It depends who is watching it.
-- A passenger on the train says that his clock is normal, but the clock at the station he just passed is running slow.
-- A ticket agent at the station says that his clock is normal, but the clock on the train that just rolled through is running slow.
-- They're both correct, but ...
-- The difference is too small for either of them to notice, unless the train is going faster than about half the speed of light.
-- It isn't.
