A 20 N force is applied to an object with a mass of 100 kg. What is theacceleration of the object?
O
O
A. 0.2 m/s2
B. 120 m/s. 120 m/s2
O
C. 80 m/s. 120 m/s2
O
D. 5 m/s. 120 m/s2

Answers

Answer 1
Answer:

Answer:

A. .2 M/s2

Explanation:

Force = mass x acceleration

The force is given as 20 N and tthe mass as 100kg

Solve for accelartion as 20/100 = .2

(Also wrong subject this is a Physics problem)
Answer 2
Answer:

Answer:

The answer is 0.2m/s^2

Explanation:

As we all know that, Force=Mass* Acceleration

So, to make acceleration the subject of the formular, we have Acceleration=Force/mass

And we were given that, Force=20N

Mass=100kg

So, Acceleration= 20/100

=0.2m/s^2

A 500 gram piece of metal has a volume of 2.75cm3 what is the density

Answers

Answer: 181.82\ g/cm^3

Explanation:

Given that the volume of a piece of metal = 2.75\ cm^3

Mass of piece of metal= 500 g

Formula to calculate the density is given by :-

\text{Density}=\frac{\text{Mass}}{\text{Volume}}

Then, the density of piece of metal is given by :-

\text{Density of piece of metal}=(500)/(2.75)\n\n\Rightarrow\ \text{Density}=181.818181818\approx181.82\ g/cm^3  [Rounded to the nearest two decimal places.]

Hence, its density of piece of metal= 181.82\ g/cm^3
density is mass / volume so it is 500 / 2.75=181.82 g/cm3
