Usimov [2.4K]

Answer: Atoms are electrically neutral because they have equal numbers of protons (positively charged) and electrons (negatively charged). If an atom gains or loses one or more electrons, it becomes an ion.

Using a mass of 1. 8 g and the volume displaced by the sample, calculate the sample's density. Question 17 options: 0. 17 g/mL 0

LUCKY_DIMON [66]

The sample's density with respect to the volume it displaces is equal to: C. 0. 60 g/mL

<u>Given the following data:</u>

Mass = 1.8 grams

Initial volume = 20 mL

Final volume = 23 mL

To calculate the sample's density:

First of all, we would determine the volume displaced by the sample;

$Volume \;displaced = 23-20$

Volume displaced = 3 mL

Density can be defined as mass all over the volume of an object. Thus, density is mass per unit volume of an object.

Mathematically, the density of a substance is given by the formula;

$Density = \frac{Mass}{Volume}$

Substituting the given parameters into the formula, we have;

$Density = \frac{1.8}{3}$

Density = 0.60 g/mL

Hitting a home run in baseball is difficult, because it requires a lot of force. Most home runs are hit off of fastballs. Which

OLga [1]

The impact force makes sense because the impulse experienced by the body cause a great change in momentum of the body.

<h3 /><h3>What is impulse?</h3>

This is the force that acts on a body over a given period of time. The impulse experienced by a body is determined as the product of force and time of action.

J = Ft

The change in momentum of a body is equal to the impulse experienced by the body.

ΔP = Ft

Thus, the impact force makes sense because the impulse experienced by the body cause a great change in momentum of the body.

An astronaut circles the earth in a satellite at an altitude of 150 km. If the diameter of his pupils is 2.0 mm and the average

Fiesta28 [93]

Answer:

d = 49.5 m

hence we can say it is conceivable that he can distinguish sports stadiums on earth's surface but in Private houses? Cars? it can not becayuse they are are very small

Explanation:

Given data

altitude = 150 km

diameter = 2.0 mm

wavelength = 550 nm

to find out

is it conceivable that he can distinguish sports stadiums

solution

we will apply here formula that is

∅ = 1.2 λ / D

put here λ = 550 × $10^{-9}$ m and D = 2 × $10^{-3}$ m

∅ = (1.2 ) 550 × $10^{-9}$ / 2 × $10^{-3}$

∅ = 3.30 × $10^{-4}$ rad

d = 150 × $10^{3}$ × 3.30 × $10^{-4}$

d = 49.5 m

hence we can say it is conceivable that he can distinguish sports stadiums on earth's surface but in Private houses? Cars? it can not becayuse they are are very small
