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:
no

the metal spoon would be higher temperature
Answer:
False
Explanation:
The direction of magnetic field on a current carrying conductor can be determined by the Fleming's right hand rule where
- The thumb represents the direction of motion
- the index finger represents the direction of field.
- The middle finger is the direction of induced current.
When two conductors carrying currents flowing in opposite direction, the magnetic field will be in the same direction hence they will repel.
<u><em>When the currents in them flow in same direction, then it means the magnetic field will be opposition and there will be a force of attraction between the conductors.</em></u>
F - False.
The nucleus of an atom is positively charge.
We don't know. A black hole is a star that has collapsed into its own gravity. The gravity in fact, is so strong that even light cannot get through it. That's why it looks black to us.
