Answer:
Explanation:
La distancia recorrida es la suma de las etapas de aceleración y velocidad constante (Travelled distance is the sum of the acceleration and constant speed stages). La aceleración es (The acceleration is):
La distancia recorrida es (The travelled distance is):
Answer:
The velocity is
Explanation:
From the question we are told that
The mass of the ball is
The radius is
The force is
The speed of the ball is
Generally the kinetic energy at the top of the circle is mathematically represented as
=>
=>
Generally the work done by the force applied on the ball from the top to the bottom is mathematically represented as
Here d is the length of a semi - circular arc which is mathematically represented as
So
Generally the kinetic energy at the bottom is mathematically represented as
=>
=>
From the law of energy conservation
=>
=>
Answer:
Visible light
X rays
ultraviolet radiation
gamma rays
microwave radiation
Explanation:
Electromagnetic waves consist of oscillating electric and magnetic fields which vibrate in a direction perpendicular to the direction of motion of the wave (transverse wave). Electromagnetic waves have all same speed in a vacuum (, known as speed of light) and are classified into 7 different types according to their frequency and wavelength. This classification is called electromagnetic spectrum.
From lowest to highest wavelength, the 7 types are:
Gamma rays
X-rays
Ultraviolet radiation
Visible light
Infrared radiation
Microwaves
Radio waves
Sound waves, on the contrary, do not belong to the electromagnetic spectrum, since they are another type of wave called mechanical waves (which consist of vibrations of the particles in a medium).
