and between 3 &4 is 
mass of freight car =37,000 kg
acceleration of car
is accelerating all freights behind 3
therefore
Thus
Answer:
She throws the wrench in the opposite direction of her destination and the resulting backward force should be enough to get her back to the station.
Answer: True
The statement " the synthesis of a large collection of information that encompasses well tested and verified hypothesis about certain aspects of natural world is known as <em>"scientific theory". </em>
It was proposed by Charles Darwin and Alfred Russel in the mid 19th century.
Typically, it is about the relationship between various facts and is a way of providing a concise explanation for what's been observed. A scientific theory is a well- substantiated explanation of an aspect of the natural world.
If the polarity of a magnet is flipped while its strength remains constant. There is no change in the electromagnetic force since there is no change in the current in the wire.
<h3>What is the faraday law of electromagnetic induction?</h3>
According to Faraday's law of electromagnetic induction, the rate of change of magnetic flux linked with the coil is responsible for generating emf in the coil resulting in the flow of the amount of current.
If a magnet's polarity were switched while maintaining the same magnetic field intensity. There is no change in the electromagnetic force, and there is no change in the current in the wire.
Hence the current in the wire will be the same as in the first part.

Answer:
273.15
Explanation:
So that's three over two times 1.38 times ten to the minus twenty-three joules per Kelvin, times 5500 degrees Celsius, the surface of the sun converted into Kelvin by adding 273.15. This works out to 1.20 times ten to the minus nineteen joules. So that's the average kinetic energy of hydrogen atoms.
