During field day elementary school students played a game of Tug of War. The team on the left exert 10 Newtons of force on their side of the rope. How much force does the team on the right have to exert to keep from being pulled over the line?
2 Newtons
5 Newtons
10 Newtons
20 Newtons
During a summer thunderstorm, Ellie observes a flash of lightning and immediately starts planning an investigation to create a static electricity experiment of her own. She rubs a plastic comb with a wool sock and holds it near some small scraps of paper, but nothing happens.
What is the most likely reason that Ellie's experiment is not working?
She did not rub the comb hard enough or long enough with the wool.
The humidity from the summer storm disperses electrons, making it difficult for her comb to keep its charge.
It is not possible to create a static charge in the comb, because only metal objects can hold a negative charge.
The charge in the comb can only be discharged to metal objects.
Which objects will change direction due to gravity. Choose all that apply.
An apple tossed in the air.
A paper airplane is thrown in the air.
A ball is rolled across the floor.
A ball is thrown across the room.
This is a crane picking up pieces of iron.
Which problem is being solved by the use of a magnet in the picture?
building tall houses for a neighborhood
moving heavy pieces of iron from the road
making iron magnetic
using a new crane
