How much net work is required to accelerate a 1000 kg from 20 m/s to 30
m/s?

Answers

Answer:

Work= force(F) * distance (s)

weight is a force and so

F=weight=mass *acceleration due to gravity

=1000*10=10000N

S=?

To find s,

F= ma

a=F/m=10000/10

a=10m/s²

Using Newton's third equation of motion

v²= u²+2as

30²= 20²+2*10*s

900–400=20s

500=20s

s=500/20= 25m

Work =F*s

Work=10000*25

Work= 250000J or 250KJ

t=bd+M solving M what's the answer

Answers

Answer:

m=−bd+t

Step-by-step explanation:

t=bd+m

flip equation

bd+m=t

Step 2: Add -bd to both sides.

bd+m+−bd=t+−bd

m=−bd+t

On solving for M, we get -  

M = t - bd

We have the following expression -

t = bd + M.

We have to solve for ' M '.

Solve for x :  nx + a = [tex]$\pi[/tex].

On solving, we get -

nx + a = [tex]$\pi[/tex]

x =  [tex]$\frac{\pi -a}{n}[/tex]

According to the question, we have -

t = bd + M

t - bd = M

M = t - bd

Hence, on solving for M, we get -  

M = t - bd

Given the following number as an approximate measurement, 49.5 feet. What is the range of values for the actual value?

Answers

Answer:

range is 2

Step-by-step explanation:

The range of values for the actual value is 2.

A range is the simplest measurement of the difference between the values ​​in a dataset. To find the range, subtract the minimum value from the maximum value and ignore the other values. Where the minimum is 155 and the maximum is 720.

The statistical range for a particular dataset is the difference between the maximum and minimum values. For example, if the specified record is {2,5,8,10,3}, the range is 10 – 2 = 8. Therefore, the range can also be defined as the difference between the highest and lowest observations.

1) : 2x + 5y = 12 a. (1,?) b. (?, 1) C. (0,?) d. (?, 0)​

Answers

Answer:

A. y = 2

B. x = 7/2

C. y = 12/5

D. x = 6

Step-by-step explanation:

A. Determination of y .

2x + 5y = 12

x = 1

2(1) + 5y = 12

2 + 5y = 12

Collect like terms

5y = 12 – 2

5y = 10

Divide both side by 5

y = 10 / 5

y = 2

B. Determination of x

2x + 5y = 12

y = 1

2x + 5(1) = 12

2x + 5 = 12

Collect like terms

2x = 12 – 5

2x = 7

Divide both side by 2

x = 7/2

C. Determination of y

2x + 5y = 12

x = 0

2(0) + 5y = 12

0 + 5y = 12

5y = 12

Divide both side by 5

y = 12/5

D. Determination of x

2x + 5y = 12

y = 0

2x + 5(0) = 12

2x + 0 = 12

2x = 12

Divide both side by 2

x = 12/2

Step-by-step explanation:

The triangle provided is an equilateral one, which means that the length of all sides is equal.

Let's start by taking two and finding x.

8x+1 = 3x+6 (Subtract 3x from both sides)

5x+1 = 6 (Subtract 1 from both sides)

5x = 5 (Divide 5 from both sides)

x = 1

Now we substitute x in all the equations to find the length.

8(1) + 1 = 9

3(1) + 6 = 9

4(1) + 5 = 9

Length = 9
