Radio Waves

Infrared Waves

Ultraviolet (UV) Waves

A magnetic field and an electric field vibrate together to produce electromagnetic waves, also known as EM waves. In other words, magnetic and electric fields that are oscillating make up electromagnetic waves (EM).

And we call these waves "electromagnetic" because they have magnetic fields in addition to electric fields. We also call them "waves" because they propagate outward in accordance with wave equations, just like all the other waves we've seen.

Transverse motion characterises electromagnetic waves. Magnetic and electric fields that are perpendicular to each other oscillate to form electromagnetic waves. The speed of electromagnetic waves through vacuum is the same, 3 x 10^8 m/s.

Compared with the sister's clock, she will notice that your clock runs slower. The conclusion can be derived from the Theory of Special Relativity.

The Theory of Special Relativity explains how the speed affects mass, time, and space.

The time slows down for observers moving relatively to each other approaching the speed of light. This is called time dilation.

The first observer will find the second observer's clock runs slower than the first observer's. At the same time, the second observer will find the first observer's clock runs slower than the second observer's.

The time dilation can be expressed as

The angular displacement of the second of a wrist watch is d)9050 radians. So, correct option is d.

We know very well that angular displacement is defines as the point through which any line or body rotates in any specified direction.

In 1 minute number of seconds are =60

In 60 minutes number of seconds are =60×60=3600

In 24 hours number of seconds are =24×60× 60=86400

So, we have total number of seconds as 86400.

Now, we know that second hand clock completes one revolution of the clock in 60 seconds.

It means, Angular displacement in 60 second = 2π  radians

Angular displacement in 1 second = 2π/60=π/30 radians

Therefore, angular displacement in 86400seconds =(π/30)×86400=2880π radians,

which is equivalent to =2880×(22/7)=9050.42radians.

Any item that can be rotated has the property of rotational inertia. It is a scalar value that indicates how challenging it is to alter an object's rotational velocity around a specific rotational axis.

The role of mass in linear mechanics is analogous to that of rotational inertia in rotational mechanics. Indeed, an object's mass affects its rotational inertia. Additionally, it relies on how that mass is distributed in relation to the axis of rotation.

It becomes harder and harder to adjust the rotational velocity of the system as a mass deviates from the axis of rotation. This makes intuitive sense given that the mass is now moving around the circle with additional momentum due to its increased speed.

This applies to a particular problem domain. The only thing that happens when two bodies collide is that their momentum changes. Thus, for bodies colliding, changes in momentum are always equal and opposite. The momentum of the other body must decrease by the same amount if the momentum of the first body increases. As a result, momentum always remains constant.

Your hand is used to raise the book so that it rises steadily. Since there is no net force exerting any force on the book, there is no total work.

A force is an influence that can alter an object's motion in physics. An object with mass can change its velocity, or accelerate, in response to a force. Force can also be conceptualized as a push or a pull. A force is a vector quantity since it has both magnitude and direction. At this level, using the terms "push" or "pull" to describe a force is entirely appropriate. A force is not something that an object "has in it" or that it "contains."

In simple harmonic motion, the acceleration is zero at the object's maximum speed. Maximum mass displacement in SHM equates to maximum acceleration. The momentum calculator uses the equation p=mv, or momentum (p) equals mass (m) times velocity (v).
