The answer is a Telescopic gauge.
A Telescopic gauge is a tow point transfer gauge that can be used with an outside micrometre to measure inside diameter.
What is Telescopic gauge?
- Telescoping gauges are indirect measuring devices used to determine the internal diameter of a bore, hole, groove, slot, or other similar structure.
- A handle, two telescopic rods, and a locking screw make up this T-shaped tool.
- Telescopic gauges with two plunging telescopic rods are available, as are those with only one.
- Telescopic gauges are used to measure the internal diameter of a bore, hole, or groove with a diameter of up to 150mm (6′′), such as camshaft bearings or connecting rod bore bearings. They are primarily used by mechanics to measure the bore size of a crankcase in an engine with moving pistons.

Answer: 0.9264 kg
Explanation: [I'll use "cc" for cubic centimeter, instead of cm^3.
The volume is 6cm*4cm*2cm = 48 cm^3 (cc).
Density of Au is 19.3 g/cc
Mass of gold = (48 cc)*(9.3 g/cc) = 926.4 grams Au
1 kg = 1,000 g
(926.4 grams Au)*(1 kg/1,000 g) = 0.9264 kg, 0.93 kg to 2 sig figs
At gold's current price of $57,500/kg, this bar is worth $53,268. Keep it hidden from your lab partner (and instructor).
Non renewable resources are resources that we can only use for so long until they’re gone and they can not be brought back. So like coal would be a non renewable resource. Renewable resources are resources that we can continue to use and we will always have them. An example of a renewable resource would be oxygen. We can breathe as much oxygen as we want but we will never run out of it.
Answer:
The magnitude of charge is 
with a positive charge.
Explanation:
Given that,
The potential due to a point charge, 
Distance, d = 15.7 m
The potential due to a point charge is given by :
q is charge
k is electrostatic constant
Here, the potential is positive, then the magnitude of charge is with a positive charge.
True because when a bar magnet or any magnet is cut in half they then start to have their own South and North Pole.
