Answer:
It inflicted psychological harm on children.
Answer:
Explanation:
Initially , crate is going upwards with uniform velocity so net force on crate is zero.
Tension T = mg ( its weight )
= 14.5 x 9.8
= 142.1 N
Now tension is increased to 180 N , so net force on it
= 180 - 142.1 = 37.9 N
Work done by tension that is 180 N
= Tension x displacement
= 180 x 1.15 x 10⁻³
= .207 J
Answer: C
Explanation: Side post terminals need to be removed to inspect them for corrosion.
Over tightening the terminal bolt can damage side post terminals.
The battery terminals and cable ends can corrode especially when the battery or car is not used for a long period of time. Corrosion limits a battery's lifespan and so should be prevented. To inspect the areas where corrosion occur on a side-post battery, you need to remove the terminals.
Also, it is true that over tightening the terminal bolt can damage the side post terminals. The covering on the battery can become twisted, and make the seals on the terminals leak.
Answer:
I say vehicle one, because both will apply the same amount of force but, because vehicle two has less mass, it will accelerate more rather than vehicle one which will accelerate less.
