What is a convenient way to show how a fixed quantity is broken down into parts?

Marysya12 [62]

A convenient way to show how a fixed quantity is broken down into parts is by using a circle graph.

A circle graph shows different fixed parts in relation to the whole. All of the parts make up the whole.

A hungry 177177 kg lion running northward at 75.575.5 km/hr attacks and holds onto a 32.332.3 kg Thomson's gazelle running eastw

ValentinkaMS [17]

Answer: 73.2 km/hr

Explanation:

This is a momentum conservation type of problem, here we need to use the fact that the initial momentum is equal to the final momentum.

Remember that the momentum is written as:

P = m*v

m = mass

v = velicity

At the beginning, we have:

A lion of 177 kg running at velocity of 75.5 km/hr

Then the momentum of the lion is P1 = 177 kg*75.5 km/hr= (13,363.5)kg*km/hr

The gazelle has a mass of 32.3 kg, and a velocity of 60.6 km/hr

Then the momentum of the gazelle is:

P2 = 32.3kg*60.6km/hr = 1,957.38 kg*km/hr

The total initial momentum is equal to P1 + P2, then we have:

P = 1,957.38 kg*km/hr + 13,363.5 kg*km/hr = 15,320.9 kg*km/hr

Now, after the lion catches the gazelle, we can think it as only one object moving with mass equal to the mass of the lion plus the mass of the gazelle and velocity V

Then the final momentum will be:

Pf = (177kg + 32.3kg)*V = 209.3kg*V

And this needs to be equal to the initial momentum, then:

209.3kg*V = 15,320.9 kg*km/hr

V = (15,320.9 kg*km/hr)/209.3kg = 73.2 km/hr

Then the final speed of the lion-gazelle system is 73.2 km/hr

The wavelength of green light is about the size of an atom. (T/F)

Snowcat [4.5K]

Explanation:

The wavelength of green light is about 500 nanometers, or two thousandths of a millimeter. The typical wavelength of a microwave oven is about 12 centimeters, which is larger than a baseball.

Planets in the solar system revolve around the Sun in an orbital path and can vary from rocky and terrestrial objects to gaseous

Yuliya22 [10]

Answer:

Gaseous; liquid.

Explanation:

A planet can be defined as a large celestial body having sufficient mass to allow for self-gravity and make it assume a nearly circular shape (hydrostatic equilibrium), revolves in an orbit around the Sun in the solar system and has a cleared neighborhood.

Some examples of the planet are Mars, Venus, Earth, Mercury, Neptune, Jupiter, Saturn, Uranus, Pluto, etc.

Basically, the planets are divided into two (2) main categories and these includes;

I. Inner planets: these planets are the closest to the sun and comprises of mercury, venus, earth and mars.

II. Outer planets: these planets are beyond the asteroid belt and comprises of jupiter, saturn, uranus and neptune, from left to right of the solar system.

These outer planets are made mostly of gases (hydrogen and helium) causing them to be less dense than the solid inner planets. These gases are generally known to be less dense in terms of physical properties.

In conclusion, Planets in the solar system can vary from rocky and terrestrial objects to gaseous and liquid object.

However, the set of characteristics which is unique to the outer planets are gaseous and liquid.
