Answer:
(b) for imparting motion to a mechanical part
Explanation:
a screw is a made of metal material usually hard metal it is mainly consist of a head at one end and a point at other end it also consist a shaft by virtue of which it can be change into other material there are many type of screw present translating type is one of them which is mostly use for imparting motion to a mechanical part
Answer:
74.12kg/day
Explanation:
Equation of reaction for the neutralization reaction of sodium hydroxide and sulfuric acid: 2NaOH + H2SO4 yields Na2SO4 + 2H2O
Mass of sulfuric acid produced per day = 90,800kg
Percentage of sulfuric acid in wastewater = 0.1%
Mass of sulfuric acid that ends up in wastewater per day = 0.1/100 × 90,800 = 90.8kg
From the equation of reaction, 2 moles of NaOH (80kg of NaOH) is required to neutralize 1 mole of H2SO4 (98kg of H2SO4)
80kg of NaOH is required to neutralize 98kg of sulfuric acid
90.8kg of sulfuric acid would be neutralized by (90.8×80)/98kg of NaOH = 74.14kg/day of NaOH

Answer:
6.30 miles/hour
Explanation:
Newton's second law applies here. In simple terms:
where F = Force (Thrust) in N
a = acceleration (m/s²)
The acceleration can be given by rearranging the formula to give:
=
