<h3><u>Answer;</u></h3>

Universe, galaxy, solar system, planet, moon

<h3><u>Explanation;</u></h3>
  • <u>A galaxy</u>, such as our Milky Way Galaxy, is a collection of solar systems orbiting around a central core.
  • <u>A solar system</u> consists of a star, normally the sun and all of its planets, asteroids, comets and other bodies.
  • <u>A planet</u> is a nearly spherical body which is in orbit around the Sun. Planets are larger than moons.
  • <u>Moons</u> are typically rocky bodies which are in orbit around planets.

Universe > Galaxy > Solar system > Planet > Moon

It's like a game of zooming in:

We exist in the universe.
Which galaxy? Milky way.
It's in the Solar system,
Which has 9 (or 8) planets.
And each planet has moons!

A 2000 kg car moving at 100 km/h crosses the top of a hill with a radius of curvature of 100 m. What is the normal force exerted
Tpy6a [65]

Answer:

The normal force the seat exerted on the driver is 125 N.

Explanation:

Given;

mass of the car, m = 2000 kg

speed of the car, u = 100 km/h = 27.78 m/s

radius of curvature of the hill, r = 100 m

mass of the driver, = 60 kg

The centripetal force of the driver at top of the hill is given as;

F_c = F_g - F_N

where;

Fc is the centripetal force

F_g is downward force due to weight of the driver

F_N is upward or normal force on the drive

F_N = F_g-F_c\\\\F_N = mg - \frac{mv^2}{r} \\\\F_N = (60 \times 9.8) -\frac{60 \ \times \ 27.78^2 \ }{100} \\\\F_N = 588 \ N - 463 \ N\\\\F_N = 125 \ N

Therefore, the normal force the seat exerted on the driver is 125 N.

An EM wave has a wave length of 956 m, What type of electromagnetic waves is this wave
Assoli18 [71]

The electromagnetic spectrum allows finding the result for the question of type of electromagnetic wave has a wavelength of 956 nm

  • The wave is in the near infrared range.

The electromagnetic wave is an oscillation of electric fields and magnets field that sustain each other, this wave time has the characteristics that it can travel without a material medium, for which they are of extreme importance.

Consequently the spectrum of electromagnetic waves to each part has been given a different name second to its use, for example

Range                        Name  

Ultraviolet light          200 to 400 nm

Visible light               400 to 700 nm

Infrared light (heat  ) 700 nm to 1 mm

The latter is subdivided into:

 Near infrared          700 nm to 1000 nm (1 μm)

 Medium infrared        1 μm  to 30 μm

 Far infrared             50 μm to 1000 μm

It indicates that the wavelength of the measured radiation is 956 nm, therefore it is in the near infrared range.

According to the chart, one gram of copper and
ad-work [718]

Answer:

C) three

Explanation:

Let gram of gold required be m . Let temperature change in both be Δ t .

heat absorbed = mass x specific heat x change in temperature

for copper

heat absorbed = 1 x .385 x Δt

for gold

heat absorbed = m x .129 x Δt

So

m x .129 x Δt = 1 x .385 x Δt

m = 2.98

= 3 g approximately .
