Question 2

Mathematics
1 answer:
s344n2d4d5 [400]3 years ago
7 0

The work is simply the dot product of the force and displacement (which I assume are given in Newtons and meters, respectively):

<em>W</em> = <em>F</em> • <em>d</em>

<em>W</em> = (5i + 3j - 2k) N • ((4i<em> - </em>j + 3k) m - (j + k) m)

<em>W</em> = (5i + 3j - 2k) • (4i - 2j + 2k) Nm

<em>W</em> = (20 - 6 - 4) Nm

<em>W</em> = 10 J

A 5.00 L air sample has a pressure of 107 kPa at a temperature of -50C. If the temperature is raised to 102C and the volume expa
joja [24]

Answer:

129.9 kPa

Step-by-step explanation:

The relationship between temperature T, volume V and pressure P is given by the ideal gas equation which is given as

K = PV/T where K is a constant such that were there is a change of temperature T₁, volume V₁ and pressure P₁ to  temperature T₂, volume V₂ and pressure P₂ then the relationship may be given

P₁V₁/T₁ = P₂V₂/T₂

where T is measured in ⁰K

T₁ = -50 + 273

= 223 ⁰K

T₂ = 102 + 273

= 379 ⁰K

5 × 107/223  = P₂ × 7/379

P₂ = 129.9 kPa

Sara drove 96 miles on 3.2 gallons of gas. How many miles can Sara drive on 12.5 gallons of gas
Blababa [14]

Answer:

375 miles

Step-by-step explanation:

Create a proportion where x is the number of miles she can drive on 12.5 gallons of gas:

\frac{96}{3.2} = \frac{x}{12.5}

Cross multiply and solve for x:

3.2x = 1200

x = 375

So, with 12.5 gallons of gas, Sara can drive 375 miles
