Answer:
The average speed is 5.8 m/s
Explanation:
I just did it
A) reversing the battery
B) reversing the nail and using the nail’s head
C) wrapping the wire around the nail more times
D) unwrapping several loops of the wire from the nail
Answer:
The correct answer is C.
Explanation:
To pick up four clips at the tip of the nail, wrap the wire around the nail more times than it already has. This is because the attraction force of the electromagnet is directly proportional to the square of the magnetic field that is generated by passing a current through the coiled wire. The magnetic field, in turn, is proportional to the number of turns that this wire has around the magnetic element, so it is necessary to increase the number of turns so that the strength of the electromagnet is greater.
Have a nice day!
C) wrapping the wire around the nail more times would enable Gazala to pick up eight more clips
The mass needs to be reduced.
The distance that the force is exerted needs to increase.
The mass needs to be increased.
Answer:
The distance that the force is exerted need to increase
Explanation:
Work is defined as the product of the force and distance in the direction of applied force.
W = Fd ………………. (i)
Equation (i) shows that work done can be changed by changing either force or distance. If you reduce force, you have to increase distance accordingly to keep work done constant.
Answer:
elliptical
Explanation:
Nicolaus Copernicus gave the heliocentric theory that sun is at the center if the solar system and all the planets and the moons revolved wound it. according to him, the planets revolved around the sun in circular paths.
But Kepler suggested a different shape of the orbit. According to the laws o planetary motion given by Kepler, the planets revolve around the sun in an elliptical orbit. The sun is at one of its focus.

A. Destructive interference
B. Diffraction subtraction
C. Diffraction gradient
D. Constructive interference
Answer: Constructive interference
Explanation: Just took the test
The diagram shows destructive interference between two waves, resulting in a smaller amplitude wave.
The type of wave interaction shown in the diagram is destructive interference.
In destructive interference, two waves combine and create a new wave with a smaller amplitude. This occurs when the crests of one wave align with the troughs of another wave, causing cancellation.
In the diagram, wave A and wave B are out of phase, meaning their crests and troughs do not align. When they combine, the resulting wave has a smaller amplitude than either individual wave, indicating destructive interference.

According to Newtons first law of motion, a passenger tends to continue in the state of uniform motion even after the accident which causes the passenger to move forward.
According to the Newtons first law of motion, an object will continue in a state of rest or uniform motion unless it is acted upon by an external force. This is also known as the law of inertia.
While in a car undergoing uniform motion and suddenly the car is involved in an accident which causes the vehicle stop abruptly, a person suddenly moves forward because of the tendency to continue in the former state of uniform motion according to Newtons first law.
A seat belt helps to prevent the person from suddenly moving forward in a way that may lead to injury as a result of the accident.

Answer:
Newtons first law of motion explains what happens in a car crash because it basically states that the passenger will continue to travel at the same velocity until an unbalanced force acts on he or she. The force that will act upon he or she would be the window, so you should always wear a seat belt!
