Question #4 i think my answer is wrong . thoughs anyone ?

Answer:

The average force applied to the ball is 84N

Step-by-step explanation:

This problem bothers on the impulse of a force

Given data

Mass of ball m= 0.28kg

Initial speed u= 0m/s

Final speed v= 6m/s

Time of impact t= 0.02s

We know that the impulse of a force

Ft= mv-mu

Hence the force is

F= (mv-mu)/t

F=m(v-u)/t

F= 0.28(6-0)0.02

F= 1.68/0.02

F= 84N

Answer:

84.6

Step-by-step explanation:

135c + 273.15 = 408 K

72C + 273.15 = 345 K

100 L over 408 K = V2 over 345 K

V2= 84.6

The volume of the gas when temperature decreases to 72.0 °C is 84.6 L

Volume is a physical quantity that measures the amount of three-dimensional space occupied by matter (solid, liquid, or gas).

Volume is defined as the three-dimensional space occupied by matter or enclosed by a surface. The SI unit of volume is the cubic meter (m³),

Given that, a sample of gas has a volume of 100.0 L at 135 °C, the pressure remains constant, we need to find that what is the volume of the gas when temperature decreases to 72.0 °C

Converting the temperature into Kelvins =,

135C + 273.15 = 408 K

72C + 273.15 = 345 K

100 L / 408 K = V2 / 345 K

V2 = 84.6

Hence, the volume of the gas when temperature decreases to 72.0 °C is 84.6 L

Answer:

well im not sure but that's what i got

Step-by-step explanation:

(20)(12)(10)=2400

2400/4= 800

The volume of the given rectangular prism is 2400 cubic inches.

Given that, a rectangular prism dimensions are length = 20 inches, width = 12 inches and height = 10 inches.

A rectangular prism is a three-dimensional solid shape with six faces that including rectangular bases. A cuboid is also a rectangular prism. The cross-section of a cuboid and a rectangular prism is the same.

Volume of a rectangular prism = Area of a base × Height.

Here, Area of a base = length × width

= 20 × 12

= 240 square inches

So, volume = 240 × 10

= 2400 cubic inches

Therefore, the volume of the given rectangular prism is 2400 cubic inches.

Answer:

220 square centimeters  Option c.

Step-by-step explanation:

There are 6 faces of a rectangular prism, so to find the surface area of the prism, add the area of each faces.

Surface Area = 2(lw + lh + wh)

where, l = Length, w = Width and h = Height of the rectangular prism.

According to the given dimensions

Length = 10 cm

Width = 4 cm

Height = 5 cm

Therefore, the surface area of the given rectangular prism will be,

S.A. = 2((10)(4) + (10)(5) + (5)(4))

       = 2(40 + 50 + 20)

       = 2 (110)

      = 220 cm²

Surface area of the rectangular prism will be 220 cm².

We have been given that a rectangular prism that has a height of 5 cm, a width of 10 cm, and a depth of 4 cm. We are asked to find the surface area of the prism.

We will use surface area of rectangular prism to solve our given problem.

[tex]A=2(lw+wh+hl)[/tex], where,

l = Length,

w = Width,

h = Height.

[tex]A=2(10\text{ cm}\cdot 4\text{ cm}+4\text{ cm}\cdot 5\text{ cm}+5\text{ cm}\cdot 10\text{ cm})[/tex]

[tex]A=2(40\text{ cm}^2+20\text{ cm}^2+50\text{ cm}^2)[/tex]

[tex]A=2(110\text{ cm}^2)[/tex]

[tex]A=220\text{ cm}^2[/tex]

Therefore, the surface area of the given prism would be [tex]220\text{ cm}^2[/tex] and option C is the correct choice.

Answer:

Isaiah included 50 songs in all of

his playlists.

Step-by-step explanation:

Each playlist has 10 songs. So if you have 2 playlists then you have 10 songs for the first playlist and 10 songs for other playlist.

In this question there are 5 playlists, so 10 + 10 + 10 + 10 + 10 =50 songs.

In mathematics you can multiply to get the answer quickly:

5 * 10 = 50

That is a lot faster and you still get the same result!

Answer:

C features a slope of +4 and a y-intercept of +2

Step-by-step explanation:

Only the middle two answers feature a slope of +4, so eliminate answers A and D.  Answer C features a slope of +4 and a y-intercept of +2

The equation of a line in slope-intercept form for a line with slope 4 and y-intercept at (0, 2) is C. y = 4x + 2.

In the slope-intercept form of a linear equation, y = mx + b, 'm' represents the slope and 'b' represents the y-intercept. If we substitute the given values into this equation, with m = 4 (the slope) and b = 2 (the y-coordinate of the y-intercept), we get y = 4x + 2. So, the correct answer is C. y = 4x + 2.

Given Function A with points (–5, –2), (–5, 7) and Function B with points (7, –5), (–2, –5) represent linear functions, thus:

Function A has an undefined slope: no slope

Equation for line A would be: x = -5

Function B has a slope value of: 0.

Equation for line B is: y = -5

Recall:

Thus:

Linear Function A with the points (–5, –2), (–5, 7):

[tex]Slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{7 -(-2)}{-5 -(-5)} \\\\[/tex]

[tex]m = \frac{9}{0}[/tex] (can't divide. Undefined)

The equation for function A will therefore be written as: x = -5

Linear Function B with the points (7, –5), (–2, –5):

[tex]Slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-5 -(-5)}{-2 - 7} \\\\[/tex]

[tex]m = \frac{0}{-9} = 0[/tex]

The equation for function A will be written as: y = -5
