Answer:
The current in the primary coil would be
.
Explanation:
Given the power supplied by a transformer is 60 watts.
And the voltage in the primary coil is 120 Volts.
We need to find the current supply in the primary coil.
We will use the formula

Where,
is the power in Watts.
is the voltage in Volts.
is the current supply in Ampere.

So, the current in the primary coil would be
.
The direction of the vector with respect to the x-axis
is the angle whose tangent is (4/5) .
Arctan(4/5) = 38.7° counterclockwise from the x-axis.
Answer:
c) 8.3 x 10^24 molecules
Explanation:
First of all, we convert the volume of the glass of water from mL to
:

The relationship between mass and volume is:

where
is the density of water
M is the total mass of the glass of water
is the volume of the water in the glass
Solving for M,

Now we know that the mass of a single molecule of water is

The total mass of the water in the glass can be written as

where
N is the number of molecules in the glass of water
Solving for N, we find:

C is the answer
