Answer:
75kg dining table
Explanation:
its the heaviest
more force would be required to push it
so it has greater inertia

1. Applying more force and energy, speeding up
2. Releasing potential and kinetic energy by going down a slope, speeding up
3. Applying less force to slow down and let friction overcome the bicyclist
Purposeful <span>Opening but with a good direction Open questions require more than a yes or no answer. </span>Encourages higher levels of thinking – Not all questions are created equal. A question that facilitates critical thinking and processing is of more value than a “got it” question (questions that are usually a repetition of content presented by the lecturer).http://blog.lifeway.com/explorethebible/blog/5-characteristics-of-a-good-question/
Answer:
ΔU= 1.3922 KJ
Explanation:
Given that
Q= 2 KJ
Note- 1 .Heat added to the system taken as positive and heat leaving from the system is taken negative.
2. Work done on the system taken as negative and work done by the system taken as positive.
P =2 atm
V₁= 2 L
V₂=5 L
Work done by the gas W
W= P ( V₂- V₁)
W= 2 ( 5 - 2)
W= 6 atm.L
1 L·atm = 0.1013 kJ
W= 0.6078 KJ
From first law of thermodynamics
Q= W + ΔU
ΔU=Change in internal energy
2 = 0.6078 + ΔU
ΔU= 1.3922 KJ
The results of the experiments should be similar.
