Blizzard [7]

Answer: D

Neither A nor B

Explanation:

In order to check the clearances for rod and main bearings, you need a set of micrometers and a dial-bore gauge

Measuring the inside diameter of a main or rod bearing will require a dial bore gauge. The best ones to use are accurate down to 0.0001-inch.

So, both technician A and B are incorrect

Goryan [66]

Answer:c=0.213 J/g/K

Explanation:

Given

sample mass $(m_s)=120 gm$

initial temperature of mineral $(T_{im})=92.6$

mass of water $(m_w)=82.9$

Water initial temperature $(T_{iw})=20$

Heat capacity of calorimeter =15.3 J/k

Final Temperature is 24.8

let c be the specific heat of mineral

Heat released by mineral sample=heat absorbed by calorimeter and water

$120\times c\times (92.6-24.8)=82.9\times 4.184\times (24.8-20)+15.3\times (24.8-20)$

$c\times 67.8=14.486$

$c=0.213 J/g/K$

Pls help Which forces are shown on a free body diagram?

valentinak56 [21]

Answer:External forces acting on an object may include friction, gravity, normal force, drag, tension, or a human force due to pushing or pulling. When in a non-inertial reference frame (see coordinate system, below), fictitious forces, such as centrifugal pseudoforce are appropriate.
