For the answer to the question above, <span>at the end, the KE = 1/2mv^2 = (1/2)(2000)(2^2) = 4000 J This must equal the net work acting on the car. W=Fd The net force is 1140-950= 190N. so, d=W/F = 4000/190 = 21.05 m
I hope my answer helped you.</span>
Answer:
whats the question
Explanation:i can help if u give the whole question
The correct answer to this open question is the following.
The J.J Thomson's plum pudding model establishes that when he researched the atom, he found that electrons are positively charged. Because he observed that electrons were embedded like plums. Electrons are negative. However, compared to the modern-day atomic theory, scientist Ernest Rutherford established that the space between an atom is empty, the nucleus of the atom is positive, and negative electrons have fixed motion paths.
Here is a very important formula. You should memorize it:
Distance = (speed) x (time) .
Here's how it's used to answer your question:
Distance = (2 m/s) x (600 seconds)
= 1200 meters .
The momentum of a neutron p = 586.25 kg m / s.
<u>Explanation:</u>
The product of mass and the velocity gives the momentum of an object and it is a vector quantity. It is denoted by the letter p. The unit of momentum is kilogram meter per second (or) kg m / s.
Given mass m = 1.675 10, velocity v = 3.500 10
Momentum, p = mv
where m represents the mass,
v represents the velocity.
momentum p = (1.675 10) (3.500 10)
momentum p = 586.25 kg m / s.
