The three properties of electromagnetic waves are; they travel at the speed of light, they include ultraviolet waves, and they can transfer energy through empty space.

<h2>Further Explanation</h2><h3>A wave</h3>

A wave is a transmission of a disturbance. It involves transmission of energy from one point which is the source to another point.
Waves may be classified depending on the need for a transmission medium or based on the vibration of particles relative to the direction of wave motion.
Waves may be either transverse or longitudinal based on the direction of wave motion relative to the vibration of particles
Additionally waves may be classified as either electromagnetic wave or mechanical based on the need for a transmission medium.

<h3>Electromagnetic waves </h3>

Electromagnetic waves are types of waves that do not require a material medium for transmission.
All waves of the electromagnetic spectrum are electromagnetic transverse waves that do not require a material medium for transmission.
They include; radio waves, microwaves, infrared, visible light, ultra-violet, x-rays, and gamma rays.
All waves of the electromagnetic spectrum travel with a speed of light, 3.0 x10^8 m/s.
Additionally, electromagnetic waves possess energy that is given by; E = hf; where h is the plank's constant and f is the frequency.

Force F → = (−8.0 N)iˆ + (6.0 N)jˆ acts on a particle with position vector r → = (3.0 m)iˆ + (4.0 m)jˆ. What are (a) the torque

disa [49]

Answer with Explanation:

We are given that

$F=-8\hat{i}+6\hat{j}$

$r=3\hat{i}+4\hat{j}$

a.We have to find the torque on the particle about the origin.

We know that

Torque= $\tau=r\times F=\begin{vmatrix}i&j&k\\3&4&0\\-8&6&0\end{vmatrix}$

By using the formula

$\tau=50\hat{k}$

b. $\mid \tau\mid =\mid F\mid \mid r\mid sin\theta$

$\mid F\mid=\sqrt{(-8)^2+(6)^2}=10$

$\mid r\mid=\sqrt{3^2+4^2}=5$

$\mid \tau\mid=\sqrt{(-50)^2}=50$

Substitute the values then we get

$50=10\times 5 sin\theta$

$sin\theta=\frac{50}{50}=1$

$sin\theta=sin90^{\circ}$

Because $sin90^{\circ}=1$

$\theta=90^{\circ}$

Why are eight electrons (four pairs) surrounding each non-hydrogen atom the optimal electronic arrangement for covalent molecule

rodikova [14]

Eight electrons surrounding each non-hydrogen atom is the optimal electronic arrangement for covalent molecules because it is needed to achieve an octet structure and is necessary to fill both the s and p subshells of electrons.

<h3>What is Covalent bonding?</h3>

This is the type of bonding which involves the sharing of electrons between atoms of an element.

This is done to achieve an octet configuration thereby making them stable and less reactive thereby making it the most appropriate choice.

A school bus moves at speed of 35 mi/hr for 20 miles. How long will it take the bus to get to school

ludmilkaskok [199]

Answer:

Explanation:

Assuming school is at the end of the 20 mile route, then

20 mi / 35 mi/hr = 0.57142...hr

which is about 34 minutes 17 seconds

PLEASE HELP ASAP!!!!!

Igoryamba

While falling, both the sheet of paper and the paper ball experience air resistance. But the surface area of the sheet is much more than that of the spherical ball. And air resistance varies directly with surface area. Hence the sheet experiences more air resistance than the ball and it falls more slowly than the paper ball.

Hope that helps!
