I think it might be immortal? Not sure what is your point
Explanation :
First considering Sid's statements, the description of tangential speed and centripetal acceleration are correct.
But for Centripetal force, the description is incorrect because centripetal force is always perpendicular to the velocity.
Sid's error can be corrected by the statement (b) i.e. "Centripetal force is perpendicular to the velocity of the satellite".
<span>It occurs whenever a magnetic field
and an electric conductor move relative to one another so the conductor
crosses lines of force in the magnetic field. The current produced by electromagnetic induction is greater when the magnet or coil moves faster, the coil has more turns, or the magnet is stronger</span>
Answer:
Sir Isaac Newton
Explanation:
The laws according to which bodies move and how one body attracts another body were developed by Newton. The three laws of motion and the law of universal gravitation were developed by Newton.
In the seventeenth century almost all the refracting telescopes exhibited color distortion. Newton believed that white light had a spectrum which was the reason for this distortion. The lens of a refracting telescope used to act like a prism which caused the dispersion of light proving Newton's hypothesis.
Answer:
The gravitational attraction between Earth and a 2,500 kg car is 24,592.49 N.
Explanation:
The law of universal gravitation, or simply the law of gravity, establishes the force with which two bodies attract each other simply because they have mass. This law was developed by Sir Isaac Newton.
This law describes the gravitational interaction between massive bodies, and establishes a proportional relationship of the gravitational force with the mass of the bodies.
The Universal Law of Gravitation states that all objects attract each other with a force directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
This means that any two bodies attract each other with a greater or lesser force depending on their mass is greater or less, and according to the distance between them.
The fundamental formula of the Law of Universal Gravitation is as follows:
Where:
-
F is the force of attraction between two masses.
- G is the universal constant of gravitation (6.673484*10⁻¹¹ N.m²/kg²).
- m1 is the mass of one of the bodies.
- m2 is the mass of another of the bodies.
- d is the distance that separates them.
In this case:
- m1: 6*10²⁴ kg
- m2: 2,500 kg
- d: 6.38*10⁶ m
Replacing:
Solving you get:
F= 24,592.49 N
<u><em>The gravitational attraction between Earth and a 2,500 kg car is 24,592.49 N.</em></u>
