Pls Help Me On This It's About Acceleration

Answers

Answer 1

Answer:

1: A b/c the table is showing that each different surface resulted in different time for acceleration.

2: D b/c the if the same force is applied to two different masses, the smaller masses would be impacted more and move faster. The larger an object is, then the greater the force you will need for it to move the same distance as the smaller masses.

neptune has an average distance to the sun of 30.06 au in two or more complete sentences explain how to calculate the orbital period of neptune ​

Answers

Answer:

As per Kepler's law we know that

\frac{T_1^2}{T_2^2} = \frac{R_1^3}{R_2^3}T22T12=R23R13

as we know that for earth the time period is 1 year and its distance is 1 AUnow from above formula we can saylet the time period of Neptune is T and its distance is given as R = 30.06 AUnow we will have\frac{1^2}{T^2} = \frac{1^3}{30.06^3}T212=30.06313by rearranging the above equation we haveT^2 = (30.06)^3T2=(30.06)3T = 164.8 yearsT=164.8years

so it will have time period of 164.8 years

How many particles are in 4g of NaCl? (1mol of NaCl = 58g) – 2 step conversion

Answers

Answer:

4.16 * 10²⁴ particles

Explanation:

1. We convert from grams to moles

4 g NaCl / 58 g of NaCl = 0.0689655172 moles

-> 0.0690 moles

2. Now we will convert from moles to particles by multiplying by avogadro's number..

0.0690 * 6.022 *10²³ = 4.15518 * 10²⁴ particles or 4.16 * 10²⁴ particles

name the two criteria that is used to determine if a substance is pure or not​

Answers

Answer:

Melting and Boiling Point Determination

The physical properties of a substance can be used to establish its purity. These properties include the melting point and boiling point. Different substances tend to have different melting and boiling points, and any pure substance will have a specific melting and boiling point.
