Answer:

See the answer below

Explanation:

a. The volume in the first measuring cylinder reads 70 cm^3 while that of the second reads 95  cm^3. Hence;

V1 = 70  cm^3

V2 = 95  cm^3

b. <u>An object will always displace its own volume in a liquid</u>. Hence:

Volume V of the rock sample = V2 - V1

   = 95 - 70 = 25  cm^3

c. Mass of A = 102 g

   Volume of A = 25  cm^3

<em>Density = mass/volume</em>

Hence, density of A = 102/25 = 4.08 g/cm^3

Solar wind particles can be captured by the Earth's magnetosphere. When these particles spiral down along the magnetic field int
Alex73 [517]

Answer:

Solar wind particles can be captured by the Earth's magnetosphere. When these particles spiral down along the magnetic field into the atmosphere, they are responsible for?

Answer is Aurorae.

Explanation:

Solar Wind:

A planet's magnetic filed forms a shield to protect the surface of planet from energetic and charged particles coming from sun and other planets. The sun is continuously  sending out charged particles , called Solar wind.

Magnetosphere of planet:

If a planet has a magnetic field then it will interact with the solar wind and deflect the charged particles in the wind. Due to which an elongated cavity in solar wind formed. This cavity is called magnetosphere of the planet.

When Solar wind particles run in a magnetic field , they are  deflected and spiral down along magnetic field lines into the atmosphere.

Most of the solar wind particles deflected around the planet but a few particles manage to leak into the magnetic filed and become trapped in the magnetic field of the planet, to create Radiation Belts or Charged Particles Belts.

Variable Solar Wind can give some radiation belt particles with enough energy to spiral down along the magnetic filed into the atmosphere and Create Aurorae

Here Aurorae is an atmospheric phenomenon consisting of Bands, streamers of light, usually yellow , green or red , that move across the sky in the polar regions.

What is the speed of a vehicle with a distance of 88 miles and a time of 4 hours????
Tanya [424]

The answer you are looking for is 22 mph.

Solution:

s=speed

d=distance

t=time

Setting up the formula for the speed of an object with distance and time:

s=d/t

Substituting the given values,

s=88 miles/4 hours

So, therefore, the final answer is 22 mph.

I hope this helped answer your question for you. Good day to you.

Do man made elements have a greater number than natural elements
Furkat [3]
A synthetic element is one of 24 chemical elements that do not occur naturally on Earth: they have been created by human manipulation of fundamental particles in a nuclear reactor, a particle accelerator, or the explosion of an atomic bomb; thus, they are called "synthetic", "artificial", or "man-made". The synthetic elements are those with atomic numbers 95–118, as shown in purple on the accompanying periodic table:[1] these 24 elements were first created between 1944 and 2010. The mechanism for the creation of a synthetic element is to force additional protons onto the nucleus of an element with an atomic number lower than 95. All synthetic elements are unstable, but they decay at a widely varying rate: their half-lives range from 15.6 million years to a few hundred microseconds.
