Answer:
a. Exactly the same as the magnitude of the charge of the proton.
Explanation:
The elementary charge (e) is the smallest electric charge that can exist in the universe. Any positive or negative electric charge can be expressed as a multiple of the elementary charge, since is the electric charge carried by a single proton or, equivalently, the magnitude of the electric charge carried by a single electron (-1e).
Answer:
33.5 kJ
Explanation:
here there is no difference is made in the temperature. Only thing happens here is the conversion of the ice in to water of 0 degree. The heat energy taken from the outside is spent for this conversion.
we have ice 100g =0.1 kg
Appplying Q=mL
Q= 
Q = 33 500 J
Q = 33.5 kJ
Answer: An equipotential surface must be perpendicular to the electric field at every point. The correct option is B.
Explanation: Equipotential surface is any surface over which the potential difference is constant. Examples include:
-The surface of a conductor in electrostatic field.
- surface of a liquid in equilibrium.
Equipotential surface are perpendicular to the electric field at every point because components of electric field intensity along the surface is zero ( this is because no work is done while moving a charge from one point to another on an equipotential surface).
Answer:
(1) Resonance
Explanation:
Resonance is the process whereby a system is set into vibration due to the vibration of a nearby system with larger amplitude. The frequency at which this vibration takes place is called the resonant frequency.
It is a phenomenon of amplification that occurs when the frequency of a periodically applied force is in harmonic proportion to the natural frequency of the system on which it acts.
