Answer: Option (b) is the correct answer.

Explanation:

A beta particle is a particle with a negatively charged electron. Symbol of a beta particle is $^{0}_{-1}\beta$ .

An alpha particles is basically a helium nucleus and it contains 2 protons and 2 neutrons.

Symbol of an alpha particle is $^{4}_{2}\alpha$ .

A gamma particle is basically a photon of electromagnetic radiation with a short wavelength.

Symbol of a gamma particle is $^{0}_{0}\gamma$ .

Therefore, we can conclude that the charge of a beta particle is 1-.

How many grams of water vapor (H2O) are in a 10.2-liter sample at 0.98 atmospheres and 26°C?

diamong [38]

Hey there!

<span>Use the equation of Clapeyron:
</span>
T in kelvin :

26 + 273.15 => 299.15 K

R = 0.082

V = 10.2 L

P = 0.98 atm

number of moles :

P *V = n * R * T

0.98 * 10.2 = n * 0.082 * 299.15

9.996 = n * 24.5303

n = 9.996 / 24.5303

n = 0.4074 moles

Therefore:

Molar mass H2O = 18.01 g/mol

1 mole H2O ------------- 18.01 g
0.4074 moles ----------- m

m = 0.4074 * 18.01 / 1

m = 7.339 g of H2O

7. A cyclist starting from rest accelerates at a rate of 6 m/s until she reaches 30 m/s. How long

Hunter-Best [27]

Answer:

Explanation:

The given values are:

a= 6m/s²

u= 0 m/s

v = 30 m/s

t= ?

The formula is :

$a=\frac{v-u}{t}$

thus,

$t=\frac{v-u}{a}\\t=\frac{30-0}{6}\\t= 5 seconds$
