Part a - obtaining conversion factors from unit equality relationships in an experiment you are performing, your lab partner has
DanielleElmas [232]

Solution:

As we given that 1 inch=2.54 cm

then using this conversion factor we can write  28.4 inch=28.4* (1 inch)

and further it can be written as

28.4* (1 inch)*(2.54 cm/1 inch)=28.4*2.54 cm= 72.136 cm

Hence the required conversion factor is 2.54 cm/1 inch as we can see from the above calculation.

Homework - Pure Year 1 - Chapter 11B
ycow [4]

Answer:

|F net| = 20.22 N

θ ≈ 19.8°

Step-by-step explanation:

F net = 15N i + 8cos(60°)N i + 8sin(60°)N j

= 15N i + 8×½N i + 8×√3/2N j

= 15N i + 4N i + 4√3N j

= 19N i + 4√3N j

|F net| = √(19²+(4√3)²) = √(361+48) = √409 ≈ 20.22N

tan(θ) = 4√3 ÷ 19 ≈ 0.36 → θ ≈ arctan(0.36) = 19.8°

The current in a simple electrical circuit is inversely proportional to the resistance. The current is 80 amps when the resistan
Oksana_A [137]
I =  / r            where I = current and r = resistance

80 = k / 50 so
k = 400

so we have I = 400/r

when r = 40  
I = 400/40 = 10 amps

Solve for x. 30x-20=50
MaRussiya [10]
30x - 20 = 50
use inverse operations to isolate x

30x - 20 = 50
+ 20 +20

30x = 70
(30x = 70) /30

x= 7/3 (this is the simplified term)
