<u>Answer:</u> The correct answer is Option C.

<u>Explanation:</u>

Covalent bond is formed when there is sharing of electrons between the atoms that are forming a bond.

When hydrogen and oxygen form a covalent bond to form a compound named water, both the atoms share electrons with each other.

Electronic configuration of Hydrogen = 1s^1

Electronic configuration of Oxygen = 1s^22s^22p^4

As, 2 electrons are required for one oxygen atom to complete its octet and 1 electron is required by the hydrogen to have a stable configuration. Therefore, 2 atoms of hydrogen shares its electrons to 1 atom of oxygen to form water.

The chemical formula for water is H_2O.

Hence, the correct answer is option C.

Assume you are a perfect blackbody at a temperature of T = 310 K. What is the rate, in watts, at which you radiate energy? (For
madreJ [45]

Answer:

P = 942.54 W

Explanation:

Given:

Temperature, T = 310 K

mass, m = 70 kg

Now from the stefan's law,

we have the formula

P = σAT⁴

where,

P = radiate energy

σ = Stefan's constant = 5.67 × 10⁻⁸ W/(m² K⁴)

A = Area of the body

Average surface area for a human body = 1.8 m²

T = Temperature

on substituting the values we get,

P = 5.67 × 10⁻⁸ × 1.8 × 310⁴

or

P = 942.54 W

In an experiment, a researcher can make claims about causation
Yakvenalex [24]
<span>In an experiment, a researcher can make claims about causation if the independent variable changes because of changes made to the dependent variable. Causation works on cause and effect, so the changed independent variable is the cause and the changed dependent variable is the effect. In an experiment the independent variable is changed to determine the dependent variables value, so the two are directly related.</span>

A beryllium-9 ion has a positive charge that is double the charge of a proton, and a mass of 1.50 ✕ 10−26 kg. At a particular in
seropon [69]

Answer:

Magnetic force, F = 3.52\times 10^{-13}\ N

Explanation:

Given that,

A beryllium-9 ion has a positive charge that is double the charge of a proton, q=2\times 1.6\times 10^{-19}\ C=3.2\times 10^{-19}\ C

Speed of the ion in the magnetic field, v=5\times 10^6\ m/s

Its velocity makes an angle of 61° with the direction of the magnetic field at the ion's location.

The magnitude of the field is 0.220 T.

We need to find the magnitude of the magnetic force on the ion. It is given by :

F=qvB\\\\F=3.2\times 10^{-19}\times 5\times 10^6\times 0.22\\\\F=3.52\times 10^{-13}\ N

So, the magnitude of magnetic force on the ion is 3.52\times 10^{-13}\ N.
