This is an example Newton's Third Law. All the kinectic energy from the moving car transferred the potential energy of the parked car. This potential is not much since the brakes are on (hopefully) and it's not in a non-moving position.
Answer:
For the first blank, the answer is decreases. For the second blank, the answer is increases. And finally for the third blank, the answer is decreases.
Explanation:
For the first blank, the answer is decreases. For the second blank, the answer is increases. And finally for the third blank, the answer is decreases.
When a liquid is cooled, the kinetic energy of the particles decreases. The force of attraction between the particles increases, the space between the particles decreases, and the matter changes its state to solid.
Answer:
E
Explanation:
All others conduct electricity and heat.
Answer:
The force must increase
Explanation:
According to newton's second law "force is the product of mass and acceleration".
Force = mass x acceleration
Now, the mass of the sports car is lesser compared to that of the truck. Therefore, to take both automobiles to the same speed, enough force must be applied by the engine of the truck.
There must be an increase in the force in order to make both automobiles attain the same speed.
Answer:
& -y direction
& +y direction
Explanation:
From the question we are told that:
Speed of electron 
+x direction
Earths magnetic field 
+z direction
a)
Generally the equation for magnetic force 
is mathematically given by
where
Magnitude & Direction
-y direction
b)
Generally the equation for magnitude and direction of the magnetic force on an electron. is mathematically given by
Magnitude & Direction
& +y direction
