Answer:
R = 25 Ohms
Explanation:
Given the following data;
Voltage (p.d) = 15 V
Current = 0.6 A
To find the resistance of the wire;
Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.
Mathematically, Ohm's law is given by the formula;
Where;
V represents voltage measured in voltage.
I represents current measured in amperes.
R represents resistance measured in ohms.
Substituting into the equation, we have;
R = 25 Ohms
Answer:
.
Explanation:
Since no external force is acting on the system.
Therefore, Total energy remains constant before and after.
So, Total energy of system= energy due to potential applied+kinetic energy

(Here v=velocity ,V=potential ,q=charge and m=mass).
Putting values .
We get,
.
At point B charged particle is moving faster as compared to point A.
Hence, it is the required solution.
Answer: The light beam will not diffract out of the prism.
Explanation: The angle the light is entering the prism is greater than the critical angle therefore total internal reflection will occur. Hope this helps :)
