Answer:

r_eq = 320 Ω

Explanation:

It is asked to find the equivalent resistance of a series circuit formed by two resistors r₁ and r₂

           r_eq = r₁ + r₂

           r_eq = 100 + 220

           r_eq = 320 Ω

with this value we can find the current that circulates through the circuit

           V = r_eq i

            i = V / r_eq

            i = 6.4 / 320

            i = 0.02 A

Answer:

The answer would be Front Line

The base line, service line, and the side lines are the part of the tennis court however front line is not a part of the tennis court. Thus, the correct option is D.

A tennis court is a 78ft long court, with a service line of 21ft from the net. The courts for singles tennis matches are 27ft wide in dimension, while the doubles matches courts are 36ft wide. The total playing area in tennis for a singles court is 2,106ft² and 2,808ft² for a doubles court.

The basic and important parts of a tennis court in both singles and doubles are the baseline, the center mark, the sidelines, the service lines, and the service boxes. The baseline is the boundary line at the ends of the tennis court, and the sidelines are the lines which mark the boundary line between in-bounds and out-of-bounds for both singles and doubles play.

Therefore, the correct option is D.

Answer:

What happens when you throw a basketball up

toward the hoop? If you are lucky, the ball sinks

into the net, scoring two points before dropping

back down to the ground. The basketball isn’t

that heavy, so why doesn’t it stay up in the air

saying, “What comes up must come down”?

This saying is a simple explanation for what

causes the basketball to fall back to the ground.

It is being acted on by an invisible force called

gravity, which is the basic force in the universe

that attracts all objects to each other.

1 Gravity has existed since the beginning of the universe. It is hard to understand how or why it

works, but we know it is always there because it holds everything in the universe in place. First,

you need to understand that there is a gravitational attraction between you and Earth, between

Earth and the Moon, and between Earth and the Sun. Even though you can’t feel it, the

gravitational attraction between you and Earth is what keeps your feet planted firmly on the

ground. Imagine spinning around and around on a merry-go-round. As long as you are holding

on, then you stay on the merry-go-round, but if you ever let go, you will fly off and land on the

ground. This is a useful analogy in visualizing the gravitational attraction between Earth and

you. Earth is spinning on its axis and thanks to gravity, you are held to your position on Eart

rather than flying out into space. Explanation: this is what i can do!:)

Answer:

I believe gravity is the most important aspect of our universe. Without it we would all be floating off into the universe. There wouldn’t be any orbits; instead, all planetary bodies would simply float around, running into each other when they crossed paths and just wandering forever.

Answer:

B

Explanation:

Generally, longer wavelengths have less energy than shorter wavelengths because the higher the frequency, the shorter the wavelength. Since radio waves have longer wavelengths than visible light, the correct answer should be B.

Answer:

Any scientific investigation in its simplest form involves collecting information, while a controlled experiment is a tightly controlled investigation that tests a hypothesis.

Explanation:

All the scientific investigations start with a particular question. The question decides what type of investigation should research take. A controlled experiment is an investigation which allows a particular variable to change and all other variable controlled to remain constant to see the effect on dependent variable to test a particular hypothesis while other types of investigations are used to increase the knowledge or information about the particular research subject.

Answer:

where is the multiple choice?

that means the parameter over another

Explanation:

that is when you say a parameter is inversely proportional to another it means what ever happens to the first parameter the opposite happens to the other parameter

Answer:

2 x 10^-8

Explanation:

the formula of wavelength is

the speed divided by frequency

so you have the speed given = 3.0x10^8m/s

and frequency = 1.5×10^16 Hz

so wavelength = 3.0x10^8m/s / 1.5x10^16 Hz

Answer: 1000 Hz · 0,5 m = 500 m/s

Explanation: speed = frequency · wavelength

Reunirán $270.

Explanation:

Para pagar la entrada al circo y comprar palomitas Daniela y María van a cooperar con $65.50 cada una. Entonces para calcular el dinero que van a reunir entre ambas debes sumar lo que aporta cada una:

$65.50 + $65.50= $131

Por otro lado, Francisco y Javier van a cooperar con $69.50 cada uno. De igual manera, para calcular el dinero que van a reunir entre ambos debes sumar lo que aporta cada uno:

$69.50 + $69.50= $139

Para conocer el dinero total recaudado, debes sumar lo que aportan tanto ellas como ellos. Esto es:

$131 + $139= $270

Reunirán $270.

The mirror reflects the light while the lens allows the light to pass through it. The lens and mirror are positioned parallel and opposite each other.

The basic difference between the lens and mirror is that mirror reflects the light while the lens allows the light to pass through it. Both are optical instruments but their laws are different.

The lens and mirror are positioned parallel and opposite each other. From the above conditions, it is observed that first, the light gets passed through the lens.

After it passes through the light got reflected. As the light reflected the mirror it again passes through the lens and converts the distributed or parallel lights into a single beam of light.

The single beam of light is known as the spotlight.

Such types of design for a spotlight use a lens and a mirror, combined with a gas-discharge lamp, to project a powerful parallel beam of light.

Hence the lens and mirror are positioned parallel and opposite to each other.

The weight of a body is dependent on the gravitational force of its location.

Weight is a force measured in Newton. It is often used interchangeably with mass, however, they are very different.

Weight refers to the mass of an object or body in relation to gravity. This means that gravity determines the weight of an object.

Weight changes as the gravitational force changes. This means that if a body is taken farther away from the surface of the earth, the weight changes because the gravitational force determines weight.

Answer:

i = 5.28 A

Explanation:

The magnetic force is given by the expression

          F = i l x B

the bold letters indicate vectors, let's write the modulus of that expression, where the direction between the conductor and the magnetic field is 90º, therefore the sine 90 = 1

           F = i l B

           i = F / l B

let's reduce the length to the SI system

           l = 10 cm (1m / 100 cm) = 0.10 m

let's calculate

           i = 12.9 / 0.1 3.6

           i = 5.28 A
