Find the slope of the line that passes through the pair of points (6, 7) and (9, 2). Find the slope of the line that passes through the pair of points (17, 9) and (5, 29).

Answers

As you have probably already learned, we calculate slope by dividing the change in vertical position by the change in horizontal position. Δy/Δx

Driving home from school one day, you spot a ball rolling out into the street (Figure 5-21). You brake for 1.20 s, slowing your 950-kg car from 16.0 m/s to 9.50 m/s.a) What was the average force exerted on your car during braking?
b) How far did you travel while braking?

Answers

a ) v = v o + a t  ( the acceleration will be negative )
9.50 = 16.0 + a * 1.2
a * 1.2 = -16.0 + 9.50
a * 1.2 = - 6.5 
a = - 6.5 : 1.2
a = - 5.4167 m/s²
F = m * a = 950 kg * 5.4167 m/s²
F = 5,145.8 N ( the average force exerted on a car during braking )
b ) d = v o - a t² / 2
d = 16.0 * 1.2 - ( 5.4167 * 1.2² / 2 ) =
= 19.20 - 3.90 = 15.30 m

Explanation:

A material that provides little or no resistance to the flow of electric current is called a(an) A. circuit / B. conductor / C. insulator / D. resistor.

Answers

The correct answer is (b.) conductor. A material that provides little or no resistance to the flow of electric current is called a conductor. A conductor is a known material that is used for a smooth flow of current with any barrier in one or more directions.

The correct answer is B) Conductor

A conductor is a material that allows for the flow of electrical charge (electrical current). This type of material provides little or no resistance to the flow of electric current. This is due to the fact that these type of materials have free electrons which conduct the flow of electrical current in any direction.

Different types of conductors have different resistances. Some types of materials are good conductors whereas some are not so good.

Some common conductors are Copper, gold, silver and aluminium.

An insulator is the an object of type of material which have a strong resistance to the flow of electric current. Some common insulators are glass, wood and plastic.
