what is the displacement of a cyclist who travels 1 mile north 1 mile east then finally 1 mile south

Answers

The displacement of a cyclist who travels 1 mile north 1 mile east then finally 1 mile south will be 1 mile in the east direction.

What is the displacement?

A displacement is a vector in engineering and mechanics that has a length equal to the shortest route between a point P's initial and final positions.

The displacement is the vector quantity that depends on the magnitude as well as direction. And follows the law of vector addition.

The cyclist who travels 1 mile north 1 mile east then finally 1 mile south. Then the diagram is drawn below.

From the graph, the displacement is given as,

Displacement = 1 - 0

Displacement = 1 mile

The displacement of a cyclist who travels 1 mile north 1 mile east then finally 1 mile south will be 1 mile in the east direction.

Nitrogen is used to proctect steel from water because nitrigen has?

Answers

Nitrogen is used to protect steel from water because nitrogen has stable physical properties that enables the nitrogen to be resistant to water molecules. Nitrogen also serves as a coat for the steel to not be corroded easily

The water at the top of a waterfall has _____ energy.potential
kinetic
heat
metabolic

Answers

I believe the answer isPOTENTIAL ENERGY. The water at the top of the waterfall has Potential Energy.Potential Energy is defined as the energy that is stored when an object is atrest. At the top of the waterfall, water will have maximum potential energy. Whenthe water falls down, it is will already have kinetic energy which is energythat is produced through continuous motion. When it is finally in the bottom,water will have maximum kinetic energy.

Answer:

The water at the top of a waterfall has __potential___ energy.

A 1200-kg car pushes a 2100-kg truck that has a dead battery to the right. When the driver steps on the accelerator, the drive wheels of the car push against the ground with a force of 4500 N . What is the magnitude of the force the car applies to the truck?

Answers

Answer:4500 N

Explanation:

Given

mass of truck $(m_t)=2100 kg$

mass of car $(m_c)=1200 kg$

as the car push the ground with a force of 4500 N so the force on the truck should also be 4500 N as they all the force is transmitted to push the truck

and their acceleration is

$a=(4500)/(1200+2100)=1.36 m/s^2$

Final answer:

Based on Newton's third law of motion, if the car is pushing against the ground with a force of 4500N, that same force is what propels the car and any object attached to it, regardless of the object's mass. Therefore, the car also applies a force of 4500N to the truck it is pushing.

Explanation:

The magnitude of force that a 1200-kg car applies to a 2100-kg truck with a dead battery can be calculated using the principles of Newtons's third law of motion which states that for every action there is an equal and opposite reaction. The force exerted by the car on the ground is equal to the force exerted by the ground on the vehicle. If the car's driving force against the ground is 4500N, as per Newton's third law, the ground also pushes the car back with the same force of 4500N. This force is what propels the car and any object it's connected with.

So, when the car is pushing this truck, it applies this same force of 4500N to the truck. Therefore, the magnitude of force the car applies to the truck is 4500N.
