In an experiment, a variable, position-dependent force F(x) is exerted on a block of mass 1.0kg that is moving on a horizontal s

telo118 [61]

Answer: correct option is C

The function F(x) for 0 < x < 5, the block's initial velocity, and the value of Ff.

Step-by-step explanation:

The total work done = P.E + K.E

K.E = 1/2mv^2

The speed V depends on the position:

0 < x < 5

Also, since work done = F × distance x

The workdone also depends on F(x)

The net force = 0 that is

F + fr = 0

Where fr = frictional force.

Therefore the best option for the hypothesis of work done will be;

The function F(x) for 0 < x < 5, the block's initial velocity, and the value of Ff.

If Mary deposits $275 in principal at an interest rate of 3.2 percent, how much interest will she earn in one year

nekit [7.7K]

Answer:

Mary earns interest in one year is $88 .

Step-by-step explanation:

Formula

$Simple\ interest = \frac{Principle\times rate\times time}{100}$

As given

If Mary deposits $275 in principal at an interest rate of 3.2 percent .

Principle = $275

Rate = 3.2%

Time = 1 year

Putting all the values in the formula

$Simple\ interest = \frac{275\times 3.2\times 1}{100}$

$Simple\ interest =\frac{880}{100}$

Simple interest = $88

Therefore the Mary earns interest in one year is $88 .

There is £80 in a pot which is shared out amongst 3 people. Anne gets £20 Mark gets £35 and Ben gets £25. What ratio of the mone

faltersainse [42]

Ratio of Anne : Mark : Ben = 20 : 35 : 25
= 4 : 7 : 5 ( total 16 parts )

Anne = 4/16 x £80 = £20

Mark = 7/16 x £80 = £35

Ben = 5/16 x £80 = £25

Hey I need help on this question not getting it, if one of you could please help me it would mean alot! Thank you!!

Answer:

A. y=-0.5x-2.5

Step-by-step explanation:

To figure out the equation of a line, use the formula y=mx+b, where x and y are the co-ordinate values, m is the slope and b is the y-intercept (where the line cuts the y-axis).

The slope, m, is calculated by dividing the y-difference (in this case, -2.5) by the x-difference (5): -2.5/5 = -0.5

From the diagram, we can see the line cuts the y-axis at (0,-2.5). Therefore b=-2.5

Sub in our values to get: y=-0.5x-2.5
