Answer:
B. 0 degrees
Explanation:
The magnetic flux through a certain area enclosed by a loop of wire immersed in a region with magnetic field is given by:

where
B is the strength of the magnetic field
A is the area enclosed by the coil
is the angle between the direction of the magnetic field and the direction of the normal to the coil
From the equation above, we see that the magnetic flux is maximum when

So when the field is parallel to the normal to the coil (so, when it is perpendicular to the coil), therefore when:

So, the correct option is
B. 0 degrees
Answer:
The charge on the droplet is
.
Yes, quantization of charge is obeyed within experimental error.
Explanation:
Given that,
Radius = 1.6μm
Electric field = 46 N/C
Density of oil = 0.085 g/cm³
We need to calculate the charge on the droplet
Using formula of force





Put the value into the formula


We need to calculate the quantization of charge
Using formula of quantization

Put the value into the formula


Yes, quantization of charge is obeyed within experimental error.
Hence, The charge on the droplet is
.
Yes, quantization of charge is obeyed within experimental error.
Explanation:
Momentum of the system is a constant when there aren't external forces..
So,When first Balls velocity is went down to zero... its momentum is also zero and beacause momentum should be a constant...now second ball must have a momentum of 20 kg * m/s
I believe the answer your looking for is A. Flammability. Because flammability is a chemical property, not a physical one. Hope this helps :)
