Answer:

No

Explanation:

Acceleration is the rate of change in velocity. Here the car maintains a constant speed, no change in velocity

Answer:

see below

Explanation:

first of all, you find the speed of sound in air

which is

speed = frequency x wavelength

so

speed = 200 x 1.5

speed = 300 m/s

speed remains the same in the same medium

so you can use speed and frequency to find wavelength

speed = frequency x wavelength

300 = 600 x wavelength

wavelength = 0.5 m

No external contact force.

Explanation:

Mass is defined as the amount of material an object contains, that doesn't change whether the object it on earth, on the moon or anywhere in space. Except the only force that is acting upon the body in gravity and they don't feel gravitational attraction towards the earth.

Answer:

Atomic mass 5

Explanation:

No. protons=Atomic mass

The atomic mass is the protons + the neutrons.

So your answer would be 5 + 6 = 11.

The correct and is A or jet streams, trade winds, and Coriolis effect

Answer:

2. Jet streams, Polar Easterlies, and Trade winds

Explanation:

It isn't one because the Coriolis effect is an effect or something that causes something else. (it causes things to curve like other winds and stuff) Not three because Sea breezes are winds that travel short distances, occur at night, at the beach, Not for because it also has Coriolis effect and it also has breezes for some reason. So, your answer will be 2.

Answer:  

to get around the Earth's atmosphere so that we can get a clearer view of the planets, stars, and galaxies that we are studying.

Explanation:

Answer:

I can only explain using the formula

Explanation:

v=f

[tex]v = f \times lamda[/tex]

v is velocity

f is frequency

lamda is wavelength ( I don't have the symbol)

therefore velocity is the product of frequency and wavelength

And since period is the inverse of frequency;

Period (T)=1/f

so we can have v=lamda/T

That's what I think

Explanation:

Halogens are elements within group 17 on the periodic table. As argon is in group 18, which means it is a noble gas. Bromine, chorine, and flourine are all in group 17, making them halogens.

Answer:

-->Phytoplankton are AUTOTROPHS

--> Both the Salmon and the grizzly bears are CONSUMERS.

--> Grizzly bears are SECONDARY CONSUMERS.

Explanation:

In an ecosystem, which is the basic functioning unit of nature, the biotic components is made up of all the living organisms in it. These organisms are divided into two main groups which includes:

--> The AUTOTROPHS: These are organisms that are able to use sunlight or chemical energy to manufacture their own food from simple inorganic substances. Since Autotrophs are the only organisms that can produce food in an ecosystem, they are also known as PRIMARY PRODUCERS. Example of autotrophs includes Phytoplankton( all green plants).

-->HETEROTROPHS: These organisms cannot manufacture their own food rather they feed on ready-made food which comes from the tissues of organisms in their environment. In an ecosystem, Heterotrophs are known as the CONSUMERS. Example of Heterotrophs includes all animals (salmon and the grizzly bears).

These biotic components of the ecosystem forms a feeding pathway through which energy and nutrients are transferred step by step among organisms. This is called a FOOD CHAIN. This feeding pathway follows a certain pattern:

--> it begins with a primary producer (Phytoplankton)

--> the primary producer is eaten by a primary consumer (salmon)

--> the primary consumer is eaten by a secondary consumer (grizzly bears)

That is the reason both the Salmon and the grizzly bears are CONSUMERS but while salmon is a primary consumer, grizzly bears are SECONDARY consumers.

If the distance between the two particles is increased to 8.44 mm, the electrical potential energy will increase because work must be done to separate two particles that attract one another. Hence option(A) is correct.

Potential energy is the energy held by an object as a result of its position relative to other objects, internal stresses, electric charge, or other factors.

The gravitational potential energy of an object, the elastic potential energy of an extended spring, and the electric potential energy of an electric charge in an electric field are all examples of common types of potential energy. The joule, denoted by the symbol J, is the unit of energy in the International System of Units (SI).

The positive and negative charges attract each other, so work must be done to separate two particles. Hence, the electrical potential energy will increase.

When a branch is added to a parallel circuit, the total resistance decreases, so the current in the circuit increases.

A parallel circuit is defined as the type of circuit in which the resistors are connected in parallel such that the current flowing through each of them is different.

Here,

The given circuit is connected in parallel combination of resistors. The current has different pathways to flow through. The voltage applied across each resistors will be the same.

Consider a parallel resistance circuit having a combination of n number of resistors with resistance R. The effective resistance of the parallel circuit can be given as,

1/Reff = 1/R₁ + 1/R₂ + 1/R₃ +....1/Rₙ

Since, the resistance is same on all resistors, we can write,

Reff = R/n

So, when adding a branch, the number of resistors, n increases. As a result, the effective resistance of the circuit decreases.

According to Ohm's law, as the resistance of a circuit decreases, the flow of current through the circuit increases.

Hence,

When a branch is added to a parallel circuit, the total resistance decreases, so the current in the circuit increases.
