Explanation:
such bad questions , how it could be around ???
<span>The answer is C)
mechanical advantage (MA = slope/height)
here length of slope = 9Hheight = H so mechanical advantage = ---- 9H/H= 9

According to Charles' law for ideal gases, at constant pressure, the volume and temperature of a given mass of gas with same number of moles are directly proportional to each other. This means, if volume increases then temperature will also increase whereas, if volume decreases then temperature will also decrease. For this reason, a small increase in volume will increase the temperature of the gas.
Therefore,
Volume ∝ Temperature in Kelvin scale.
V ∝ T
Density=mass/volume
density=2/8
density=0.25g/ml
it would be b hope i helped
