Answer:

If earth's gravity was to disappear then a lot would happen, but I believe the biggest impact on losing gravity is earth's un-stabilized core, gravity keeping earth's core stable would lead to the earth melting or would lead to its core being ripped apart into outer space, the impact on other planets its huge as well because the gravity keeps the earth in orbit and without it, earth will start roaming around the solar system bumping into planets which would lead to the entire solar system exploding. I hope this helped.

Answer : The mass of $NaN_3$ required is 71.175 grams.

Explanation :

To calculate the moles of nitrogen gas, we use the equation given by ideal gas :

PV = nRT

where,

P = Pressure of nitrogen gas = 763 torr

V = Volume of the nitrogen gas = 40.0 L

n = number of moles of gas = ?

R = Gas constant = $62.364\text{ L.torr }mol^{-1}K^{-1}$

T = Temperature of helium gas = $25^oC=273+25=298K$

Putting values in above equation, we get:

$763torr\times 40.0L=n\times 62.364\text{ L.torr }mol^{-1}K^{-1}\times 298K\\\\n=1.642mol$

Now we have to calculate the moles of $NaN_3$ .

The balanced chemical reaction is:

$2NaN_3(s)\rightarrow 2Na(s)+3N_2(g)$

From the balanced chemical reaction, we conclude that

As, 3 moles of $N_2$ produced from 2 moles $NaN_3$

So, 1.642 moles of $N_2$ produced from $\frac{2}{3}\times 1.642=1.095$ moles $NaN_3$

Now we have to calculate the mass of $NaN_3$ .

Molar mass of $NaN_3$ = 65 g/mol

$\text{Mass of }NaN_3=\text{Moles of }NaN_3\times \text{Molar mass of }NaN_3$

$\text{Mass of }NaN_3=1.095mole\times 65g/mole=71.175g$

Therefore, the mass of $NaN_3$ required is 71.175 grams.

Trees are part of the biosphere. They need water to survive. They take in water from the soil through their roots and release wa

dolphi86 [110]

Answer:

Explanation:

The hydrosphere represents the total amount of water on earth. Soil water is part of the hydrosphere.

The lithosphere represents the varieties of rocks present on the planet, including their weathered part which is the soil.

The atmosphere represents the different gas layers surrounding the earth.

The biosphere represents the portion of the earth that supports life.

<em>When soil water moves into the tree through the roots of the tree, the hydrosphere, the lithosphere and the biosphere are interacting all together. When the some of the water taken in is released to the atmosphere as vapor through evapotranspiration, it represents an interaction with the atmosphere.</em>

A hovering mosquito is hit by a raindrop that is 50 times as massive and falling at 8.9 m/s , a typical raindrop speed. How fast

Ivahew [28]

Answer:

v = 8.72 m/s

Explanation:

To find the speed of the raindrop joint to the mosquito, you take into account the momentum conservation law for an inelastic collision. Before the collision the total momentum of raindrop and mosquito must be equal to the total momentum of both raindrop and mosquito after the collision.

$m_1v_1+m_2v_2=(m_1+m_2)v$ (1)

v1: speed of the mosquito before the collision= 0 m/s (it is at rest)

v2: speed of the raindrop before the collision = 8.9 m/s

m1: mass of the mosquito

m2: mass of the raindrop = 50m1 (50 time more massive that the mosquito)

v: speed of both raindrop and mosquito after the collision

You solve the equation (1) for v and replace the values of the rest of the parameters:

$v=\frac{m_1v_1+m_2v_2}{m_1+m_2}=\frac{m_1v_1+50m_1v_2}{m_1+50m_1}\\\\v=\frac{0m/s+50(8.9m/s)}{51}=8.72\frac{m}{s}$

hence, after the inelastic collision the speed of the raindrop andmosquito is 8.72 m/s

A coin is resting on the bottom of an empty container. The container is then filled to the brim three times, each time with a di

Virty [35]

Answer:

Refractive index of liquid C > Refractive index of liquid B > Refractive index of liquid A

Explanation:

Let the depth of each section is h.

That means the real depth for each section is h.

Apparent depth is liquid A is 7 cm.

Apparent depth in liquid B is 6 cm.

Apparent depth in liquid C is 5 cm.

by the formula of the refractive index

n = real depth / apparent depth

where, n is the refractive index of the liquid.

For liquid A:

$n_{A}=\frac{h}{7}$ .... (1)

For liquid B:

$n_{B}=\frac{h}{6}$ ..... (2)

For liquid C:

$n_{C}=\frac{h}{5}$ ..... (3)

By comparing all the three equations

nc > nB > nA

Refractive index of liquid C > Refractive index of liquid B > Refractive index of liquid A

Interrelationship between health population and environment education and Science and Technology

S_A_V [24]

Answer:

Answer: Science and technology are relatively modern developments. For most of the past 50,000 years of civilization, there was religion, dogma, ritual an tradition. These kept civilization safe but prevented growth.

After the modern scientific method was developed during the Rennaisance, civil action took off.

Health, as expressed as life expectancies, has increased massively. Population growth has increased to levels thought impossible before. But yes, the environment has suffered.
