D)
Density is equal to mass/volume, so in your case:
density=1.3/1000=0.0013 g/cm^3

Answer:

Density, $d=0.0013\ g/cm^3$

Explanation:

Given that,

Mass of the air, m = 1.3 grams

Volume of the air, $V=1000\ cm^3$

The density of the air is given by total mass divided by total volume. Mathematically, it is given by :

$d=\dfrac{m}{V}$

$d=\dfrac{1.3\ g}{1000\ cm^3}$

$d=0.0013\ g/cm^3$

Hence, this is the required solution.

In a displacement versus time graph, what does the slope of a line at any point indicate?

Rom4ik [11]

In a displacement versus time graph, the slope of the line at any point on the graph indicates the <em>magnitude of velocity</em>.

(It can't indicate velocity completely, because the graph shows nothing about the direction of the motion.)

In 3 meters a person running 0.5 m/s accelerates 1.2 m/s 2. How fast were they going afterward? Choose the right equation for th

Feliz [49]

Answer:

2.72 m/s

Explanation:

In 3 meters a person running 0.5 m/s accelerates 1.2 m/s².

It means,

Distance, s = 3 m

Initial velocity, u = 0.5 m/s

Acceleration, a = 1.2 m/s²

We need to find the final velocity of the person. Using equation of motion to find it as follows :

$v^2-u^2=2as\\\\v^2=2as+u^2\\\\v^2=2\times 1.2\times 3+(0.5)^2\\\\v=2.72\ m/s$

So, the final velocity of the person is 2.72 m/s.

Rainbow [258]

Answer:

13.309 m/s²

Explanation:

Length from shoulder to hand, l = 30 cm = 0.3 m

initial velocity, u = 1 m/s

final velocity, v = 2.5 m/s

time, t = 3 s

Let the tangential acceleration is a.

by using first equation of motion

v = u + at

2.5 = 1 + 3 a

a = 0.5 m/s²

Let the centripetal acceleration is a'.

a' = v'²/l

a' = 2 x 2 / 0.3

a' = 13.3 m/s²

The tangential acceleration and the centripetal acceleration are both perpendicular to each other. So, the net acceleration is given by

$A=\sqrt{a^{2}+a'^{2}}$

$A=\sqrt{0.5^{2}+13.3^{2}}$

A = 13.309 m/s²
