See the person on the right side of the front car. Six reference points could be used to show that the person is in / is NOT in
motion. They are:
**a person standing on the ground **the car **the seat
**another person on the ride **the track **the sun
**a person standing on the ground **the car **the seat
**another person on the ride **the track **the sun
1 answer:
1. According to person standing on ground ~
- The person is in motion
2. According to The car ~
- The person is not in motion
3. According to the Seat ~
- The person is not in motion
4. According to another person on ride ~
- The person is not in motion
5. According to the track ~
- The person is in motion
6. According to the Sun ~
- The person is in motion
I hope that's what you were looking for, goodluck for your assignment ~

Answer:
that best describes the process is C
Explanation:
This problem is a calorimeter process where the heat given off by one body is equal to the heat absorbed by the other.
Heat absorbed by the smallest container
Q_c = m ce (-T₀)
Heat released by the largest container is
Q_a = M ce (T_{i}-T_{f})
how
Q_c = Q_a
m (T_{f}-T₀) = M (T_{i} - T_{f})
Therefore, we see that the smaller container has less thermal energy and when placed in contact with the larger one, it absorbs part of the heat from it until the thermal energy of the two containers is the same.
Of the final statements, the one that best describes the process is C
since it talks about the thermal energy and the heat that is transferred in the process
Answer:
B = 62.9 N
Explanation:
This is an exercise on Archimedes' principle, where the thrust force equals the weight of the liquid
B = ρ g V
write the equilibrium equation
T + B -W = 0
B = W- T (1)
use the density to write the weight
ρ = m / V
m = ρ V
W = ρ g V
substitute in 1
B = m g -T
B = g V - T
To finish the calculation, the density of the material must be known, suppose it is steel \rho_{body} = 7850 kg / m³
calculate
B = 7850 9.8 1.20 10⁻³ - 29.4
B = 92.3 - 29.4
B = 62.9 N
