Answer:
The value of current generated would increase.
Explanation:
Electromagnetic induction is the process by which an electromotive force is induced due to a variation of magnetic field.
The induced current is directly proportional to rate at which the coil cuts the magnetic field. Using more powerful battery in the experiment would increase the rate at the the coil cuts the magnetic field, therefore increasing the rate of variation in the magnetic field. This effect would cause a greater deflection on the galvanometer's scale, showing an increase in the current generated.
This experiment proves that an alternating current can be produced from magnetic field.
Answer:
The forces of attraction are weak in gases.
Explanation:
Solid-state objects are presented as bodies in a definite form; their atoms are often intertwined into narrowly defined structures, which gives them the ability to withstand forces without apparent deformation. They are generally described as hard as well as resistant, and in them, the forces of attraction are greater than those of repulsion. In the crystalline solids, the presence of small intermolecular spaces gives way to the intervention of the bond forces, which place the cells in geometric forms.
Solid – In a solid, the attractive forces keep the particles together tightly enough so that the particles do not move past each other. Their vibration is related to their kinetic energy. In the solid the particles vibrate in place.
Liquid – In a liquid, particles will flow or glide over one another, but stay toward the bottom of the container. The attractive forces between particles are strong enough to hold a specific volume but not strong enough to keep the molecules sliding over each other.
Gas – In a gas, particles are in continual straight-line motion. The kinetic energy of the molecule is greater than the attractive force between them, thus they are much farther apart and move freely of each other. In most cases, there are essentially no attractive forces between particles. This means that a gas has nothing to hold a specific shape or volume.
Answer:
yes the formula of pressure is P = F/A
<h2>The frequency depends upon the source energy of electromagnetic waves</h2>
Explanation:
The energy of electromagnetic wave is
E = h ν
E is the energy of source emitting the waves
here h is Plank's constant
and ν is used for the frequency of the electromagnetic wave
Thus the frequency of wave depends upon the energy of electromagnetic source . Because h is constant .
