Answer:
The heat loss during the process = -4000 J
Explanation:
Work done by the student (W) = - 1000 J
Negative sign on the system is due to work done on the system.
Decrease in internal energy (U) = - 3000 J
We know that heat transfer in the system is given by (Q) = U + W
⇒ Q = - 1000 - 3000
⇒ Q = - 4000 J
This is the value of heat transfer during the process And negative sign indicates that heat loss during the process.
Explanation:
6% grade
=> Rises 6 feet for every 100 feet traveled
This would mean that tanx = 6/100.
=> x = tan^-1(6/100) = 3.4°. (1d.p.)
Hence the road is inclined at an angle of 3.4° above the horizontal.
Answer:
Magnitude of the third vector: 57.85 cm
The direction of the third vector: 44.76 N of W
Explanation:
The vertical component of force exerted by the hi.nge on the beam will be,142.10N.
To find the answer, we need to know more about the tension.
<h3>
How to find the vertical component of the force exerted by the hi.nge on the beam?</h3>
- Let's draw the free body diagram of the system.
- To find the vertical component of the force exerted by the hi.nge on the beam, we have to balance the total vertical force to zero.
- To find the answer, we have to find the tension,
- Thus, the vertical component of the force exerted by the hi.nge on the beam will be,
Thus, we can conclude that, the vertical component of force exerted by the hi.nge on the beam will be,142.10N.

I believe the correct answer from the choices listed above is option D. The proportion of carbon-14 in an organism is useful in figuring out the age of that organism after it dies because <span>the proportion of carbon-14 slowly decreases after the death of the organism. Hope this answers the question.</span>
