Which is the longer amount of time,<br> 1351 ps or 1.2 ns? Explain answer.
Furkat [3]

We have that since 1.351ns>1.2 ns

1351 is the longer amount of time 1.2 ns

From the question we are told

The longer amount of time,

1351 ps or 1.2 ns

Generally the equation for the Pico second to Nano seconds is  is mathematically given as

1 pico second=0.001 Nano second

Theretofore

1351 picosecond=1.351 nano second

Since

1.351ns > 1.2 ns

Hence

1351 is the longer amount of time 1.2 ns

Water has a mass per mole of 18.0 g/mol, and each water molecule (h2o) has 10 electrons. (a) how many electrons are there in 7.7
arsen [322]

Answer: a) 2.58\times 10^{27} electrons are present is 7.74 L of water.

b)2.7\times 10^{8} Coulombs is the net charge of all these electrons

Explanation:

a) Molar mass of the water = 18 g/mol

Volume of water = 7.74 L

Density of water = 1000 g/L

Mass of water in 7.74 L of water :

density=1000 g/L=\frac{mass}{volume}=\frac{mass}{7.74 L}

Mass of the water = 7740 g

Moles of water =\frac{\text{mass of water}}{\text{molar mass of water}}=\frac{7740 g}{18 g/mol}=430 moles

1 mol=6.022\times 10^{23}molecules

Number of water molecules in 430 moles:

430\times 6.022\times 10^{23} =2.58\times 10^{26}molecules

1 molecule water contains = 10 electrons

Then2.58\times 10^{26} molecules=2.58\times 10^{26}\times 10=2.58\times 10^{27} electrons

2.58\times 10^{27} electrons are present is 7.74 L of water.

b) The net charge of all these 2.58\times 10^{27} electrons:

Charge on 1 electron =-1.602\times 10^{-19} Coulombs

The net charge of all these 2.58\times 10^{27} electrons:

2.58\times 10^{27}\times 1.602\times 10^{-19} C=2.7\times 10^{8} Coulombs

2.7\times 10^{8} Coulombs is the net charge of all these electrons

The image of the object formed by the lens is real, enlarged and inverted. What is the kind of lens ?​
Artist 52 [7]

Answer:

Converging (convex) lens.

Explanation:

A lens can be defined as a transparent optical instrument that refracts rays of light to produce a real image.

Basically, there are two (2) main types of lens and these includes;

I. Diverging (concave) lens.

II. Converging (convex) lens.

A converging (convex) lens refers to a type of lens that typically causes parallel rays of light with respect to its principal axis to come to a focus (converge) and form a real image. Thus, this type of lens is usually thin at the lower and upper edges and thick across the middle.

Basically, the image of the object formed by a converging (convex) lens. lens is real, enlarged and inverted.
