Answer:
Explanation:
The resistance column is correct.
I1 = I2 = I3 = I4 = 2 Amps
So all the currents are the same.
R = 110
I = 2 amps
V = ?
Vt = I * R
Vt = 2 * 110
Vt = 220
=============
V1 = 20 * 2 = 40 volts. That's 40 volts dropped from the right side of R1 to the left side.
V2 = 60 * 2 = 120 volts across the 60 ohm resistor
V3 = 30 * 2 = 60
Total voltage = 40 + 120 + 60
Total voltage = 220 which is just what it should be.
==========================
Power
P1 = V1 * I
P1 = 40 * 2
P1 = 80 watts
P2 = 120*2
P2 = 240
P3 = 60 * 2
P3 = 120
Total Power = 80 + 240 + 120
Total Power = 440
To develop this problem we will apply the Archimedes model. As well as the definitions of Weight based on mass and acceleration. The first in turn will be considered under the relationship of Density and Volume. From the values given we have to:
Since it is in equilibrium, the weight of the object will have a reaction from the water, which will cause the sum of forces between the two objects to be zero, therefore
The value of gravity is canceled because it is a constant
The portion of the object that is submerged corresponds to 82%, while the portion that is visible, above the water level will be 18%
Answer:
Newton's first law, an object will stay at rest only if there are no external forces acting on the object or if the net external force acting on the object is zero. Since the barbell is at rest (not moving), the net external force acting on it must be zero
Newton's Second Law of Motion via the equation f = ma, or put differently, force is equal to mass multiplied by acceleration. To generate more force, we must either increase mass or acceleration (or both)
Newton's Third Law of Motion is known as the equal and opposite reaction principle
Answer:
The minimum thickness of the oil is 77.55 nm
Explanation:
Given:
Refractive index of oil 
Refractive index of water 
Wavelength of light 
m
From the equation of thin film interference,
The minimum thickness is given by,
Where 
,
thickness
Here we have to find minimum thickness so we use 
m
nm
Therefore, the minimum thickness of the oil is 77.55 nm
Answer:
The arrows always start at the magnet's north pole and point towards its south pole. When two like-poles point together, the arrows from the two magnets point in OPPOSITE directions and the field lines cannot join up. So the magnets will push apart (repel).
