It Increases. I just took a quiz with the same question.
If a car is travelling 70 m.p.h that means it is travelling 70 miles PER HOUR and since we want to know half an hour we can do
70mph divided by 2 =35m.p half hour so the car is travelling 35miles in half an hour
Italian physicist Alessandro Volta discovered that particular chemical reactions could produce electricity, and in 1800 he constructed the voltaic pile (an early electric battery) that produced a steady electric current, and so he was the first person to create a steady flow of electrical charge.
We don't know that at all. The 3rd law says that the REaction is opposite and EQUAL to the action. We don't know where that "twice as much" comes from.
The initial velocity of Ms. Stafford is
, while her acceleration is
This is a uniform accelerated motion, so we can calculate the total distance travelled by Ms. Stafford in a time of
using the law of motion for a uniform accelerated motion:
