Answer:

Hey there

Boiling point-the temperature at which liquid becomes gas.*

*for water that is 100 c*

Density-the amount of gas in a given volume.**

** the density of water is 997kg/m³

Soliditiy-the ability of a substance to dissolve in another.***

***You would dissolve if you were inside the sun.

Conductivity-the ability of a substance to transfer heat or electricity.****

****metal transfers both heat and electricity efficiently.

Buoyant force-the upward force on an object in a fluid.*****

*****You float in water because you are lighter than water.

Hope it helped

The atomic mass of an atom do not contain electrons because

Dimas [21]

Answer:

Electrons are so small that it does not affect the mass of atom .

Explanation:

Electrons are much smaller in mass than protons, weighing only 9.11 × 10^-28 grams, or about 1/1800 of an atomic mass unit. Therefore, they do not contribute much to an element's overall atomic mass.

Victoria has a crate of vegetables that weighs 100 newtons she exerts a force of 100 Newtons to lift the crate with a pulley wha

miskamm [114]

By definition, the mechanical advantage is the relationship that exists between the output force or load lifted and the value of the force applied.

Thus, using the definition, we have that the mechanical advantage is given by:

$MA = \frac{100}{100}\\MA = 1$

Therefore, the mechanical advantage of lifting the box by using a pulley is equal to 1.

Answer:

The mechanical advantage in this situation is:

Equal to 1

A wave has a wavelength of 0.5 m and a frequency of 5.0 Hz. What is the speed of the wave?

mylen [45]

The correct option is (A) 2.5 m/s

Explanation:
Since,

v = fλ ---- (1)

where v = speed of the wave
f = frequency of the wave = 5 Hz
λ = wavelength of the wave = 0.5

Plug in the value in (1):
(1) => v = 5 * 0.5
v = 2.5 m/s
