If an object aquires additional energy, it is also aquiring additional: a) taxes b) vitamins c) mass d) pressure e) buoyancy
1 answer:
Answer:
Option c) mass
Explanation:
With the increase in energy in energy of an object there will be an increase in its mass.
Also from Einstein's mass-energy equivalence,
where
m = mass of the object
c = speed of the object (usually speed of light or close to it)
which states that energy and mass are inter convertible.
From which it can be concluded that if an object acquires additional energy, it also acquires additional mass.

Answer:
The magnitude of a uniform electric field that will stop these protons in a distance of 2 m is 1.01 x N/C
Explanation:
given information,
kinetic energy, KE = 3.25 x J
proton's mass, m = 1.673 x kg
charge, q = 1.602 x C
distance, d = 2 m
to find the electric field that will stop the proton, we can use the following equation:
E = F/q
= (KE/d) / q , KE = Fd --> F = KE/d
= KE/qd
= (3.25 x J) / (1.602 x
C)(2 m)
= 1.01 x N/C
Answer:
The force exerted by X on Y is F to the right, and the force exerted by Yon X is F to the left.
Explanation:
There are two objects X and Y. Mass of object X is 2M, that is moving with a speed of and that of object Y is M that is moving with a speed of
.
When both of the objects collide, the magnitude of the forces F the objects exert on each other is equal to :
The force exerted by X on Y is F to the right, and the force exerted by Yon X is F to the left using Newton's third law of motion. Hence, the correct option is (c).
