Electricity is NOT a part of electromagnetic spectrum.

An electromagnetic spectrum contains electromagnetic radiations arranged according to frequencies and wavelength.

<h2>Further Explanation </h2><h3>Electromagnetic waves </h3>

Electromagnetic waves are types of waves that do not require a material medium for transmission.
These waves are mostly transverse in nature, which means the direction of transmission is perpendicular to the direction of vibration of particles.
They include, light waves, radio waves, x-rays, infra-red, etc.

<h3>Electromagnetic spectrum </h3>

An electromagnetic wave shows electromagnetic waves arranged according to frequencies and wavelength.
Electromagnetic spectrum contains electromagnetic waves: Gamma rays, x-rays, Ultraviolet, Visible light, infra-red, microwaves, and radio waves.
The electromagnetic spectrum is divided into various sections based on wavelength, with gamma rays having the shortest wavelength and radio waves having the longest wavelength.
The part of the electromagnetic spectrum that we can see using our naked eyes is called the visible light spectrum.
In order of frequency, the radio waves have the lowest frequency while gamma rays have the largest frequency.

<h3>General characteristics of electromagnetic waves </h3>

They travel with the speed of light (3.0 x 10^8 m/s)
They possess energy that is given by; E =hf, where h is the plank’s constant and f is the frequency.
They are transverse in nature, and therefore, the wavelength is measured between successful crests or troughs.
They can travel through vacuum

Explanation :

The electromagnetic spectrum shows the wavelength or frequency range of any wave.

It consists of the following waves :

Gamma rays (short wavelength or high frequency)
X-rays
Ultraviolet rays
Visible light
Infrared rays
Microwaves
Radio waves (long wavelength or short frequency)

So, the purple light is not the part of the electromagnetic spectrum.

Hence, the correct option is (c).

A rock is thrown upward from the level ground in such a way that the maximum height of its flight is equal to its horizontal ran

marshall27 [118]

Answer

a) For the rock

$\dfrac{v_t^2sin 2\theta}{g} = \dfrac{v_t^2sin^2\theta}{2g}$

$2sin\thetacos\theta = \dfrac{sin^2\theta}{2}$

$2cos\theta = \dfrac{sin\theta}{2}$

$tan\theta = 4$

$\theta = tan^{-1} 4$

$\theta = 76^0$

b) $\theta = 45^0$ for maximum range

$\dfrac{d_{max}}{d}=\dfrac{(v_tcos 45^0)(2v_tsin 45^0)g}{(v_tcos 76^0)(2v_tsin 76^0)g}$

$\dfrac{d_{max}}{d}=\dfrac{0.707\times 0.707)}{0.97\times 0.242}$

$\dfrac{d_{max}}{d}=2.129$

$d_{max}=2.129 d$

c) The value of θ is the same on every planet as g divides out.

Calculate the force needed to give a car of mass 800 kg an acceleration of 2.0 ms−2. plss quick

erik [133]

The force needed to give a car of mass 800 kg an acceleration of 2.0 ms-² is 1600N.

<h3>How to calculate force?</h3>

The force needed to push an object can be calculated by multiplying the mass of the object by its acceleration as follows:

Force = mass × acceleration

According to this question, a car of mass 800 kg has an acceleration of 2.0 ms−². The force is calculated as follows:

Force = 800kg × 2m/s²

Force = 1600N

Therefore, the force needed to give a car of mass 800 kg an acceleration of 2.0 ms-² is 1600N.
