Answer: The net force acting on the car 1,299.3 N.
Explanation:
Mass of the car = 710 kg
Initial velocity of the car of the ,u= 37 km/h= 10.27 m/s 
Final velocity of the car,v = 120 km/h = 33.33 m/s
time taken b y car = 12.6 sec
v-u=at
The net force acting on the car 1,299.3 N.
Answer:
Explanation:
From the question we are told that:
Focal length of lens 
Image distance 
Height of image 
Generally the lens equation is mathematically given by
Where 
is Subject
Therefore the distance between the person and the car is
The the drift velocity of the electrons is determined by atom vibrations in the crystal lattice.
<h3>How to explain the information?</h3>
Assume we could increase the average time between collisions in a typical metal to get to a limit of zero resistance. The free electrons would therefore be continuously accelerated by a constant applied voltage, according to the classical paradigm of conduction. Both the current and the drift speed would gradually pick up over time.
Although it is not the scenario implied by the question, it is possible to switch to zero resistance by using a superconducting wire instead of the usual metal. In this scenario, the maximum current is constrained, the drift velocity of the electrons is determined by atom vibrations in the crystal lattice, and it is difficult to produce a potential difference across the superconductor.

Burning carbon compounds produces carbon monoxide and carbon dioxide.
The most popular sources of carbon compounds used for burning are
coal, oil, and natural gas, collectively referred to as "fossil fuels".
Answer:
It sticks to the wall due to electrostatics.
Explanation:
When pam rubs a balloon against his hair, and holds it up against the wall, he is basically adding a surplus of electrons which are negative charges to the surface of the balloon.
This motion would make the wall the more positively charged than the balloon. Therefore, when the two charges come in contact with each other, the balloon will stick to the wall because of the rule in electrostatics that opposite charges attract each other.
