Answer:
1. Acceleration
Explanation:
Newtons Second law gives the measure of acceleration
Big Bang, what sort of instrument would it be best to use: gravity.
The force of attraction between any two objects in the universe is known as gravity or gravitational force.
The mass of the object and the square of the distance between them determine the force of attraction. The weakest known force in nature, it is by far. There are only two factors that matter when discussing the gravitational force between two objects: mass and distance.
The square of the distance between two things has an inverse relationship with the force of gravity, which depends directly on the masses of the two items. The best theories of string theory propose that gravity is so weak because, in contrast to other forces, it may enter and exit these extra dimensions. We only get to taste a tiny bit of gravity's tremendous power.

Answer: The beaker containing pure water has decreased more.
Explanation:
In both cases, the decrease of water level is due to evaporation. We know that evaporation is a surface phenomenon. In the case of salt water, the salt molecules somewhat hinders the evaporation process of the water molecules and hence the salt water evaporates at a slower rate than pure water.
Hence, pure water level falls more.
The 2 sides of magnet are called the north and south pole
Answer:
So, when an electrical charge passes through a resistor, some of that electrical energy is transferred into heat, increasing the temperature. This extra energy causes the particles in the resistor to vibrate more. With these particles moving more, it is more difficult to for the electrons to move through the resistor.
