In physics class, Carrie learns that a force, F, is equal to the mass of an object, m, times its acceleration, a. She writes the

equation F=ma.
Using this formula, what is the acceleration of an object with F=7.92 newtons and m=3.6 kilograms? Express your answer to the nearest tenth

Answer:

Step-by-step explanation:

1st step is by rearranging the formula

F=ma

M=f/a

A=f/m

2nd step is use the acceleration formula

A=f/m (acceleration=force divided by mass)

3rd step answer the question using the formula

A=?

F= 7.92N

M=3.6Kg --- 3600g (optional)

A=7.92/3600= 0.0022N/g or 7.92 / 3.6= 2.2N/Kg

4th step turning them to the nearest tenth

0.0022N/g= 0.0N/g or 2.2N/Kg= 2.2N/kg

DONE

TO SEE IF THE ANSWER IS CORRECT USE THE F=MA formula

Answer:

2 m/ s

a = F / m

a= 7.92 / 3.6

ie . 2.2 m/ s

  • Let x be the percentage of p.
  • Therefore,
  • m\% \:  \: of \:  \: n = x\% \:  \: of \:  \: p \\  =  >  \frac{mn}{100}  =  \frac{px}{100}  \\  =  > mn =  \frac{px}{100}  \times 100 \\  =  > mn = px \\  =  >  \frac{mn}{p}  = x

<u>Answer:</u>

<u>\frac{mn}{p}</u>

Hope you could get an idea from here.

Answer:

1) 109 cm

2) 120 in²

Step-by-step explanation:

A rectangle is a quadrilateral with opposite sides the same length and four (4) right angles. The diagonal, together with two adjacent sides, forms a right triangle. The relationship between side lengths and the diagonal length is given by the Pythagorean theorem. If sides are "a" and "b" and the diagonal is "c", that theorem tells you ...

... c² = a² + b²

1) c² = (60 cm)² + (91 cm)² = 11881 cm²

... c = √11881 cm = 109 cm

2) The perimeter is double the sum of adjacent side lengths, so ...

... 2(a+b) = 46 in

... a + b = 23 in . . . . . divide by 2

The Pythagorean theorem tells you

... a² + b² = (17 in)²

Squaring the equation from the perimeter relation gives ...

... (a + b)² = (23 in)² = a² + 2ab + b²

Subtracting a² + b², we have

... (a² +2ab +b²) - (a² + b²) = (23 in)² -(17 in)²

... 2ab = (529 -289) in² = 240 in² . . . . . simplify

... 240 in²/2 = ab = 120 in² . . . . . area is the product of length and width

_____

We could solve the two equations for a and b to find that there are two possible solutions: (a, b) = (8, 15) or (15, 8). Either way, ab = 8·15 = 120.

In a right triangle, the sum of the squares of the legs is equal to the square of the hypotenuse. This can be used to test any triangle.
