Yasir is trying to build an energy-efficient wall and deciding what materials to use. How can he calculate the thermal resistanc

777dan777 [17]

Answer:

Add the thermal R values of each wall layer.

Explanation:

Fiberglass insulation R value, sheetrock, sheathing, siding etc. All sum together to one composite opposition to heat transfer/loss.

Q= U x A x Delta T

Q= heat transfer btuh

U= 1/R inverse of resistance

A= area of surface

Delta T is temerature difference across the wall.

Suppose the loop is moving toward the solenoid (to the right). Will current flow through the loop down the front, up the front,

Tems11 [23]

Answer:

See explanation

Explanation:

The magnetic force is

F = qvB sin θ

We see that sin θ = 1, since the angle between the velocity and the direction of the field is 90º. Entering the other given quantities yields

Effect AC

Effect AD

Effect BC

Effect BD

Effect CD

Answer :

A = significant

B = significant

C = Non-significant

D = Non-significant

AB = Non-significant

AC = significant

AD = Non-significant

BC = Non-significant

BD = Non-significant
