A body travels at an initial speed of 2.5 m/s. Given a constant acceleration of 0.2 m/s 2 what is the speed of the body at time

garri49 [273]

Answer:

<u>We are given:</u>

u = 2.5 m/s

a = 0.2 m/s/s

t = 25 seconds

v = v m/s

<u>Solving for 'v':</u>

From the first equation of motion:

v = u + at

Replacing the values

v = 2.5 + (0.2)(25)

v = 2.5 + 5

v = 7.5 m/s

If the humidity in a room of volume 410 m3 at 25 ∘C is 70%, what mass of water can still evaporate from an open pan? Express you

Keith_Richards [23]

Answer:

$m=1864.68\ g$

Explanation:

Given:

volume of air in the room, $V=410\ m^3$

temperature of the room, $T=25+273=298\ K$

<u>Saturation water vapor pressure at any temperature T K is given as:</u>

<u /> $p_{sw}=\frac{e^{(77.3450 + 0.0057\times T - \frac{ 7235}{T} )}}{T^{8.2}}$ <u />

putting T=298 K we have

$p_{sw}=3130\ Pa$

<u>The no. of moles of water molecules that this volume of air can hold is:</u>

Using Ideal gas law,

$P.V=n.R.T$

$n=\frac{P_{sw}.V}{R.T}$

$n=\frac{3130\times 410}{8.314\times 298}$

$n=518\ moles$ is the maximum capacity of the given volume of air to hold the moisture.

Currently we have 80% of n, so the mass of 20% of n:

$m=(20\%\ of\ n)\times M}$

where;

M= molecular mass of water

$m=0.2\times 518\times 18$

$m=1864.68\ g$ is the mass of water that can vaporize further.

How does the location of the outer planets explain their composition and characteristics?

Elena-2011 [213]

Jupiter, Saturn, Uranus and Neptune collectively make up the group known as the jovian planets. The general structures of the jovian planets are opposite those of the terrestrial planets. Rather than having thin atmospheres around relatively large rocky bodies, the jovian planets have relatively small, dense cores surrounded by massive layers of gas. Made almost entirely of hydrogen and helium, these planets do not have solid surfaces.

Which of the following is a balanced chemical equation? MgF 2 + Li 2CO 3 ⟶ MgCO 3 + LiF 2Al + 6HCl ⟶ 3H 2 + AlCl 3 P 4 + 3O 2 ⟶

IRISSAK [1]

P₄ + 3O₂ ⟶ 2P₂O₃

Explanation:

A balanced equation is any equation that complies with the law of conservation of matter and mass.

The law of conservation of matter states that "in a chemical reaction, matter is neither created nor destroyed but simply rearranges. ".

This suggests that the total number of atoms on both reactant and product sides must be the same in a balanced chemical equation. Also, the same atoms are found on both sides of a chemical equation with no additional or external species.

Now let us check if the equation is conserved:

P₄ + 3O₂ ⟶ 2P₂O₃

Atoms reactant product

P 4 4

O 6 6

We see that we have equal number of atoms on both sides. The equation is balanced.
