Answer:
The total applied force on the trolley is 5 N toward the North.
Explanation:
In this problem, Ben is pushing the trolley to north and Gary is pushing it to south. So both the forces are acting 180° opposite to each other. As force is a vector quantity, the net force or total force acting on any object should be calculated by vector addition of number of forces along with their directions. So in this case, if we consider the force Ben is applying as F1 and the force Gary is applying as F2 on the trolley. Then the net or total force acting on the trolley will be . This is because, F1 and F2 are acting opposite to each other in direction.Thus, .
So the total force acting on the trolley is 5 N and it is toward the north direction.

Answer:
Magnets stick to the fridge door because, underneath the paint, the door is made of steel. Magnets are attracted to certain metals, and if the attraction is strong enough they can hold on even when upside down. ... This means that a magnet will always be attracted to the door. But an iron nail does not have any magnetic properties. So it doesnt get attracted.

Change the chlorine and the oxygen around
Answer:
Glucose
Respiration
Oxygen
Explanation:
Cellular respiration can be shown with this word equation:
glucose + oxygen => water vapour + carbon dioxide + ATP energy
Our body uses cellular respiration to produce the energy our cells need for us to survive.
We get glucose from the food we eat, especially carbohydrates.
In this process, oxygen breaks down glucose (food) to produce ATP energy.
