Answer:
(C) , The wires repel
Explanation:
We are given that
Length of wire=L=7 m
We have to find the magnitude and direction of the force that the two segments of this cord exert on each other.
Where
Using the formula
When the wires carrying current in equal current in opposite direction then, the wire repel to each other.
Hence, the wires repel to each other.
Reaction: Na + Br → Na⁺Br⁻
Ion formed = Br⁻
As bromine is gaining an electron here, it is "Reduced"
Hope this helps!
Answer:
Radiation
Explanation:
radiation is The emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles which cause ionization.
Convection is within liquids, like boiling water.
Conduction is in solids, like leaving a metal fork in a hot pan.
...Brainliest?
I agree with Todd. One time when we went to the beach this happened and the waves brought back the ball so…
:) (can you mark me brainliest?)
Option (d) is correct. 800 calories of heat is released.
Explanation:
The formula for the heat is given by
Q= m L
Q= heat energy
m= mass =10 g
L= latent heat of fusion=80 cal/gram
so Heat energy= Q= 10 (80)=800 cal
the heat energy is released.
so 800 calories of heat is released.
