Answer:
when the mass of the bottle is 0.125 kg, the average height of the beanbag is 0.35 m.
when the mass of the bottle is 0.250 kg, the average maximum height of the beanbag is 0.91m.
when the mass of the bottle is 0.375 kg, the average maximum height of the beanbag is 1.26m.
when the mass of the bottle is 0.500 kg, the average maximum height of the beanbag is 1.57m.
Explanation:
<span>Assuming the car is travelling in the same direction for the entire hour, the acceleration is zero.</span>
<span>It is important to use the Système Internationale (SI) units to describe motion, and other scientific concepts, firstly because the units are the most widely used. Unit choice is largely arbitrary, however, because many scientific units are derived from the base SI units, for example, the Newton is kg m s-2. Thus, secondly, more complex units are based on the bedrock of the SI units.</span>
The amount of energy needed to increase the temperature of a substance by
is given by:
where
m is the mass of the substance
Cs is the specific heat capacity of the substance
is the increase in temperature
In our problem, m=50.0 g,
(specific heat capacity of water) and
, therefore the amount of energy needed is
