Answer:

The families are thought to form as a result of collisions between asteroids. In many or most cases the parent body was shattered, but there are also several families which resulted from a large cratering event which did not disrupt the parent body (e.g. the Vesta, Pallas, Hygiea, and Massalia families).

A negative charge -0.550 HC exerts an upward 0.700 N force on an unknown charge 0.220 m directly below it. (a) What is the unkno

Sonja [21]

Answer:

Part a)

$q_2 = -6.8 \mu C$

Part b)

$F = 0.700 N$

direction = downwards

Explanation:

As we know that the negative charge will experience the force due to some other charge below it

the force is given as

$F = 0.700 N$

now we know that

$F = \frac{kq_1q_2}{r^2}$

now plug in all data

$0.700 = \frac{(9 \times 10^9)(0.550\mu C)q_2}{0.220^2}$

$0.700 = 1.022\times 10^5 q_2$

$q_2 = -6.8 \mu C$

since this is a repulsion force so it must be a negative charge

Part b)

As per Newton's III law it will exert equal and opposite force on it

So here the force on the charge below it will be same in magnitude but opposite in direction

so here we have

$F = 0.700 N$

direction = downwards

Gold has a density of 19.32 g/cm3. what is the volume of a sample of gold with a mass of 27.63 grams?

schepotkina [342]

Answer: The volume is: " 1.430 cm³ " .
_____________________________
Explanation:
________________________
Volume, " V = ? ; (unknown, we need to solve for this).
Density, "D = 19.32 g / cm³ ;
mass , "m" = 27.63 g ;
_____________________________________________
The formula for density is:
____________________________________________
D = m / V ; Divide each side of the equation by: "(1/m)" ;
to isolate " V" on one side of the equation; and to solve for "V" ;
____________________________________________
1/m)*D = (1/m) * (m / V) ;
_______________________________
to get:
_______________________________
D/m = ; ↔ 1 / V ; Take the reciprocal of EACH SIDE; to isolate "V" on each side of the equation:
_____________________________
m / D = V/1 ↔ V = m / D ;
_____________________________
V = m / D ;
_______________________________
Now, plug in our given values for mass, "m" ; and Density, D"; to solve for "Volume, V " ;
_____________________________________
V = m / D = (27.63 g) ÷ (<span>19.32 g / cm</span>³) ;

= (27.63 g) * (1 cm³ / 19.32 g) ;

= (27.63 ÷ 19.32) cm³ ;

=   1.4301242236024845 cm³ ;

→ Round to "4 significant figures" ;
= 1.430 cm³ .
____________________________________________
The volume is: " 1.430 cm³ " .
______________________________________________
