Yes they are equivalent because 7x5=35 and 8x x 5=48x

Explanation:
Allison can measure the mass of the rock by using a scale. An electronic beam balance will be able to give her the mass of the rock to a fairly accurate degree.
To go about measuring the volume of the rock, an indirect approach has to be adopted since the rock is not regular in shape. Allison would have to adopt a principle that explains that the volume a solid body displaces when immersed in a pool of liquid, is directly equal to the volume of the solid itself.
This means that if the stone is placed in a beaker of water containing an already measured volume of water, the increase in the volume of the water when the stone is immersed is equivalent to the volume of the stone.
Answer:
(a) Total north component = (26.89 + 25) = 51.89 metres
(b) Total west component = (-34.83 + 52) = 17.17 metres.
Explanation:
Do northwest components first.
North component = (sin 33.9 x 44) =26.89 metres.
West component = (cos 33.9 x 44) = -34.83metres.
Total west component = (-34.83 + 52) = 17.17 metres.
Total north component = (26.89 + 25) = 51.89 metres
Acceleration = (change of speed) / (time for the change)
Change of speed = (speed at the end) - (speed at the beginning)
Change of speed = (55 m/s) - (30 m/s)
Change of speed = 25 m/s
Acceleration = (25 m/s) / (12.5 seconds)
<em>Acceleration = 2 m/s²</em>
