Answer:
132.64m/s
Explanation:
Averagevelocity= distance/time
From the question, the distance d = 825m
time t = 6.22 secs
Using the above formula
We have
average velocity = 825/6.22
= 132.64m/s

Answer:
b. they can be observed and measured
Explanation:
Matter is anything that has weight and occupy space. There are three states of matter namely Solid, liquid and gas.
The properties of matter are both physical and chemical in nature. Both properties can be measured and observed. Phhysical properties are anything that can be measured without changing the state of the matter. Example of physical properties includes mass, volume, length, color etc.
Chemical properties is another properties of matter. This is the ability of the states of matters to combine with other substance to form a new product for example, rusting of iron, formation of salt etc.
All this as discussed are both measurable and can be observed.
Answer:going uphill; downhill.
Explanation:A steep road is a road has a that 45-degree pitch and both mean that a run descends one vertical foot for each horizontal foot. For a one way mountainous road,if two vehicles meet at a steep point, the enabling traffic law states that the vehicle going uphill must back up for the one going downhill to pass through. This is to prevent any form of accident,as the vehicle descending will be coming with a very high velocity than the one trying to go uphill.
