Answer:
A) the same current flows in each one.
Explanation:
When resistors are connected in series, Ohm's law states that the current flowing through each resistor is the same. Since it is similar to Ohm's law for a single resistor, except that the series resistors appear as a sum. Then, the total resistance of a series circuit is equal to the sum of the individual resistors.
Answer:
Number of revolution made by tire is 1.57 x 10⁷
Explanation:
Radius of tire, r = 0.220 m
Circumference of tire, C = 2πr
Substitute the value of r in the above equation.
C = 2 x π x 0.220 m = 1.38 m
Total distance covered by tire in a year, D = 13500 miles
But 1 mile = 1609.34 m
So, D = 13500 x 1609.34 m
Number of revolutions take by tire, N = 
N = 15743543
Answer:
Acceleration of the elevator = 13.242 m/s2.
Explanation:
Force is defined as the push or pull on an object with mass in kg that causes a change velocity. Force as a vector means it has both magnitude and direction.
Mathematically,
F = M*a
Where
F = force in Newton.
M = mass of the object in kg.
a = acceleration due to gravity in 9.81 m/s2.
Acceleration of the elevator = 821/62
= 13.242 m/s2.
Newton's 2nd law of motion says
Net force = (mass) x (acceleration)
Plug in the things you know, and you have
80 N = (20 kg) x (acceleration)
Divide each side by (20 kg) :
80N / 20kg = acceleration
acceleration = 4 m/s²
Answer:
Waxing Gibbous
Third quarter
Waning Gibbous
Explanation:
If moon rises at 3:00 pm then the phase of the moon will be "Waxing Gibbous".
This is because, the moon is actually not fully illuminated but has achieved more than half of its full illumination.
If the moon is highest in the sky at sunrise then the phase of the Moon will be the "Third quarter"
This is because of the fact that at this position moon will rise at midnight, thus it will be at the highest point at the time of the sunrise.
If the moon sets at 10:00 am then the phase of the Moon is "Waning Gibbous"
This is because of the fact that at this position the Moon is moving towards becoming new Moon but at the same time, the moon is illuminated more than its half illumination.
