Option (A) and option (D) are the correct answers.

Transverse waves and electromagnetic waves correctly describe the wave used by police , i.e. ultraviolet light.

<h3>What are transverse waves?</h3>

A transverse wave is an oscillating wave in physics that <u>advances in the opposite direction of its </u><u>oscillations</u>. A longitudinal wave, on the other hand, moves in the direction of its oscillations. Transverse waves <u>include </u><u>water</u><u> </u><u>waves</u>.

<h3>What are electromagnetic waves?</h3>

In terms of science, electromagnetic radiation is made up of electromagnetic field waves that are traveling through space while carrying radiant electromagnetic energy. It consists of X-rays, gamma rays, microwaves, infrared, light, and radio waves. These waves are all a component of the electromagnetic spectrum.

How can you use a ticker tape timer in describing motion graphically?
Bad White [126]
Ticker Tape analysis is a common way of analyzing the motion of the objects to perform in the physics laboratory. A long tape is attached to a moving object and threaded through a device that places a tick upon the tape at regular intervals of time. This ticker tape can also determine if the object is fast or slow. It can also reveal if the object is moving with a constant velocity or accelerating. The changing velocity and acceleration represented by the changing distance between dots in the ticker tape. And also the constant velocity and therefore no acceleration represent the constant distance between dots.

What are Sir Issac Newton's three laws of motion?
Likurg_2 [28]
The first law is that every object stay at rest or stay in uniform motion in a straight line until it is forced to change its state by the action of an external force. This law is called law of inertia.

The second law is that the acceleration of an object is dependent upon two variables. the net force acting upon the object and the mass of the object.  F= ma or force is equal to mass times acceleration. This law is known as the law of force and acceleration.  

The third law is that for every action there is an equal and opposite reaction.  every interaction there is a pair of forces acting on the two interacting objects. the size of forces on the first object equals the size of the force on the second object. 

Hope this helps :) 

can you please make this the brainliest answer it would really help . Thanks

One of two nonconducting spherical shells of radius a carries a charge Q uniformly distributed over its surface, the other carri
lisabon 2012 [21]

Answer:

Explanation:

A ) The spheres are non conducting , charge will not move on the surface so neutralization of charge by + ve and - ve charge is not possible. Charges will remain intact on them . The electric field inside them will be zero . Electric field outside shell  will not be spherically symmetrical . Lines of force will emanate from the surface of positively charged shell  outwardly oriented  and end at negatively charged shell .

B )

distance between the centres of spherical shell

= 2 a

potential energy of charges

= k q₁ x q₂ / R

= k x - Q x Q / ( 2a )

= - k Q²/ 2a

So work needed to separate them to infinity will be equal to

= k Q²/ 2a
