Answer:
i really hope this helps "One of the advantages of parallel circuits is that they ensure all components in the circuit have the same voltage as the source. For instance, all bulbs in a string of lights have the same brightness."
Explanation:
Answer:
complete reflection of a ray of light within a medium.
Explanation:
Answer:
One should draw a diagram showing the placement of the charges.
When both charges of -Q are placed there will be no force in the vertical direction because of cancellation of forces.
A line from one corner of the square to the other makes an angle of 45 degrees,
2 cos 45 deg will be the force due to one charge.
2 * .707 = 1.41 N
So for both charges the force is (horizontal, vertical is zero)
2 * 1.41 = 2.82 N
b) is correct
Answer:
Explanation:
3.64 x 10⁶ J passes through 6 walls
heat energy passing through 1 wall = 0.606 x 10⁶ J
Surface Area of 1 wall A = .285² = 0.081225 m²
Temperature Difference = T₁ - T₂ = 26.8 + 94.7 = 121.5
Thickness of wall d = 3.75 x 10⁻² m
Rate of heat flow per second R =
=7.01 J per s.
Formula for rate of heat flow
R =
Where K is thermal conductivity.
7.01 =
K = 2.66 X 10⁻² W m⁻¹s⁻¹
