Draw

Weight is known as the gravitational force exerted on an object and is calculated by W=m*g. Calculate the weight of a duck if it has a mass of 4.4 kg.

Open Ended

Newton's Third Law of Motion states that objects act on each other with equal and opposite forces. In the case of the Earth and Moon, what does this mean? Does the moon affect the Earth due to this law?

Dropdown

A person standing on Mt. Everest (the highest point on Earth) would weigh​​ ​

Select answer

that same person standing in Death Valley (the lowest point in North America).

Draw

Draw some electric field lines for these two charges. Include arrows to show the direction of flow!!
