Ответ:
40 - 20 = 20
20/4 = 5m/s
The difference in velocity divided by the rate = acceleration.
Ответ:
It wil sink in water.
Explanation:
The law of bouyancy states that objects with lower densitiy than the liquid they´re submerged in will float, and if the object has a density of 1.35 g/ml, it wil sink in water because the density of water is 1g/ml, so because of the law of bouyancy and because the object has a greater density than water, when submerged in water the object will sink.
