Explanation:
Plant cells have several structures not found in other eukaryotes. In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls allow plants to have rigid structures as varied as wood trunks and supple leaves; and vacuoles allow plant cells to change size.
Answer:
0.3 sec : -0.4 m
0.5 sec: -1.2 m
0.7 sec: -2.3 m
Explanation:
0.3 sec: 1/2(-9.3 m/s^2)(0.3 s)^2 = -0.4 m
0.5 sec: 1/2(-9.3 m/s^2)(0.5 s)^2 = -1.2 m
0.7 sec: 1/2(-9.3 m/s^2)(0.7 s)^2 = -2.3 m
Answer:

Explanation:
Answer : The final temperature of the aluminum and ethylene glycol is
Explanation :
In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.
where,
= specific heat of aluminum =
= specific heat of ethylene glycol =
= mass of aluminum = 13.60 g
= mass of ethylene glycol = 23.27 g
= final temperature of aluminum and ethylene glycol = ?
= initial temperature of aluminium =
= initial temperature of ethylene glycol =
Now put all the given values in the above formula, we get:
Therefore, the final temperature of the aluminum and ethylene glycol is
