There is no factor on your list of choices that has any effect.
Reactants
In a chemical reaction, the substances that undergo change are called reactants. The new substances formed as a result of that change are called products.
Explanation:
a) How much work is done by gravity?
- w = f x d
- w = 950 x 10 x 5.5 = 52250j
b) How much work is done by tension?
- v²=u²+2as
- 0.75²=0.25²+2a x5.5
- 0.56=0.06+2a x5.5
- 2a x5.5 = 0.56 - 0.06
- 2a x 5.5 =0.5
- 11a=0.5
- a = 0.5/11 = 0.05m/s²
w = f x d
w = 950 x 0.05 x 5.5 = 261.25j
Answer:
solids are strong and compact, they are not compressable.
liquids are flexible and less compacts they can not be coompresed
