Answer:
2 N
Explanation:
Neglecting friction, air resistance, and gravitational pull, the force on the backpack feels like 2 Newtons. This is because we have a +6N force towards the right and -4N towards the left (left means negative and right means positive).
Summing them up, we get 2N. Now the total force differs if there are external forces acting on the backpack.
Hey there!
Each machine preety much have the same type of concept. Let's take for example, a screw. What is a screw? A screw is simply a long/small little "stick" that is able to 'twurl' it's way inside a hole, and hold it's self tight, and also take it's self right back out.
Now, based on the other 5 machines, we can see that it would be very similar of the screw. There would be a in and out function, left to right function, up and down function, and a rounded function, such as a pulley. Those would be the advantages of these different types of machines.
I hope this helps you!
Answer:If kinetic energy increases, so does the thermal energy, and vice versa.

Answer:
It allows people in different places and different countries to use the same units, avoid mistakes and understand each other more easily. The common base 10 of all units makes it easier and has more accurate calculations that are made without cumbersome conversion factors.
The strength between two objects usually depends on two factors, mass and distance. T<span>he force of </span>gravity<span> the masses exert on each other. If one of the masses of an object is doubled, the force of </span>gravity<span> between the two or more objects is doubled.
