A woman applies a force of 300 Newtons to push a stroller 100 meters. It takes her
60 seconds to perform this work. Use the equations W = Fd and P = W x T
calculate her power.

A Woman Applies A Force Of 300 Newtons To Push A Stroller 100 Meters. It Takes Her60 Seconds To Perform

Answers

Answer 1

Answer:

Work done by the woman is 500 joule per second.

Step-by-step explanation:

Force applied by the woman = 300 Newtons

Total displacement due to force = 100 meters

Work done = Force applied × Displacement due to force

                   = 300 × 100

                   = 30000 Joule

Since, Power = [tex]\frac{\text{Work done}}{\text{Time taken to perform the work}}[/tex]

                      = [tex]\frac{W}{t}[/tex]

                      = [tex]\frac{30000}{60}[/tex]

                      = 500 Joule per second

Therefore, work done by the woman is 500 joule per second.

A cylindrical jar of jam has a diameter of 6cm and a height of 8cm if the jar is 70% full how many cubic centimeters of jam is in the jar?

Answers

Answer:

[tex] 158.256 \: {cm}^{3} [/tex]

Step-by-step explanation:

For cylindrical jar:

Diameter = 6 cm

Radius (r) = 6/2 = 3 cm

Height (h) = 8 cm

[tex]V_{cylindrical \: jar} = \pi {r}^{2} h \\ \\ = 3.14 \times {(3)}^{2} \times 8 \\ \\ = 3.14 \times 72 \\ \\ = 226.08 \: {cm}^{3} \\ \\ \because \: jar \: is \: filled \: upto \: 70 \% \\ \\ \therefore \: V_{jam} = 70 \% \: of \: V_{cylindrical \: jar} \\ \\ \therefore V_{jam} = 0.70 \times 226.08 \\ \\ \therefore V_{jam} = 158.256 \: {cm}^{3} [/tex]

Please tell me if what I did is correct, and if it's wrong can you help me?

Answers

Answer:

This answer is correct I got it right on khan.

Step-by-step explanation:

We plot the given vertices (−7.5, 0), (0,6.5), (5.5, 5.5), (6.5,0), (0, -4.5) on the graph we get pentagon as shown below.

The given vertices are (−7.5, 0), (0,6.5), (5.5, 5.5), (6.5,0), (0, -4.5).

We need to plot the given vertices on the graph.

How to plot the given points on the graph?

A point in a plane contains two components where order matters! It comes in the form (x, y) where x comes first, and y comes second.

The x-value tells how the point moves either to the right or left along the x-axis. This axis is the main horizontal line of the rectangular axis or Cartesian plane.The y-value tells how the point moves either up or down along the y-axis. This axis is the main vertical line of the rectangular axis or Cartesian plane.

We plot the given vertices (−7.5, 0), (0,6.5), (5.5, 5.5), (6.5,0), (0, -4.5) on the graph we get pentagon as shown below.

If the domain of f(n) = -4n - 3 is (-1, 1/4,4}, what is the range?

O(-1, 2, -19)
O(-7,-4, -13)
O {1,-4, -19)

Answers

Answer:

[tex]Range= \{1,-4,-19\}[/tex]

Step-by-step explanation:

Given

[tex]f(n) = -4n - 3[/tex]

[tex]n = \{-1,1/4,4\}[/tex] --- domain

Required

Determine the range

To do this, we simply substitute the values of n in the given expression

So, we have:

[tex]n = -1[/tex]

[tex]f(-1) = -4 * -1 - 3 =4 - 3 = 1[/tex]

[tex]n = 1/4[/tex]

[tex]f(-1) = -4 * 1/4 - 3 =-1 - 3 = -4[/tex]

[tex]n=4[/tex]

[tex]f(-1) = -4 * 4 - 3 =-16 - 3 = -19[/tex]

Hence, the range is:

[tex]Range= \{1,-4,-19\}[/tex]
