Which wavelength would scientists use to measure the molecular structure of H2O?

Physics
1 answer:
Ne4ueva [31]3 years ago
7 0

Answer:

To find out what water is made of, it helps to look at its chemical formula, which is H2O. This basically tells us that the water molecule is composed of two elements: hydrogen and oxygen or, more precisely, two hydrogen atoms (H2) and one oxygen atom (O).

Which correctly describes electric potential, electric field, and electric (or electrostatic) force?
vlabodo [156]

Answer:

E

Explanation:

A vector is a physical quantity that has magnitude and direction while a scalar is a physical quantity that has magnitude only

*electric potential is a scalar quantity because it only has magnitude

*electric field and electric force are vector quantities because they have magnitude and direction

An instructor wishes to determine the wavelength of the light in a laser beam. To do so, she directs the beam toward a partition
Rus_ich [418]

Answer:

λ = 623.2 nm

Explanation:

We are given;

separation distance; d = 0.195 mm = 0.195 × 10^(-3) m

interference pattern distance; D = 4.85 m

Width of two adjacent bright interference; w = 1.55 cm = 1.55 × 10^(-2) m

Formula for fringe width is given as;

w = λD/d

Where λ is wavelength

Thus;

λ = dw/D

λ = (0.195 × 10^(-3) × 1.55 × 10^(-2))/4.85

λ = 0.0000006232 m

Converting to nm gives;

λ = 623.2 nm

If the cross-sectional area of a wire is decreased while all other factors remain the same, how will the resistance change?
Nataly [62]

Answer:

A. It will increase

Explanation:

Area of a wire is:

R = ρL/A

where ρ is the resistivity of the wire,

L is the length of the wire,

and A is the cross-sectional area.

If A decreases, while ρ and L stay the same, then R will increase.
