Answer:
The answer to your question is the letter B. R = 8/7 Ω
Explanation:
Data
R1 = 2 Ω
R2 = 4Ω
R3 = 8Ω
To calculate the total resistance use the formula
1/R = 1/R1 + 1/R2 + 1/R3
-Substitution
1/R = 1/2 + 1/4 + 1/8
- Look for the Greatest common factor
2 4 8 2
1 2 4 2
1 2 2
1
The GCF = 2 x 2 x 2 = 8
-Sum up the fractions
1/2 + 1/4 + 1/8 = (4 + 2 + 1) / 8
= 7/8
-Find R
1/R = 7/8 then, R = 8/7 Ω
On isolated ground receptacles, the metal yoke is not allowed to be integrally bonded to the equipment grounding terminal of the receptacle.
Any device with two distinct switches or receptacles is a duplex device. It can be shaped to fit a Decora opening or a typical duplex plate opening. It should be noted that they can be combination devices with a switch/outlet, switch/pilot light, etc.
Because of grounding connection removal and receptacle, it is utterly undesirable to connect the two bare equipment grounding conductors together directly.
The equipment grounding conductor associated with those circuits must be connected to the box when circuit conductors are terminated on equipment inside a metal box to prevent unneeded current discharge.

Answer:
Its a ceramic
Explanation:
Brick does not contain any metal so it couldnt be an alloy.
Answer:
I believe the answer is speed up.
Explanation:
this is because when water heats up the molecules move father apart from each other they speed up, eventually causing the water to boll
The normal force would be the opposing and equal force to gravity ... that is why the box isn't floating or going through the ground ... this is Newton's third law of motion
