Find the acceleration of an object that has a mass of 6 kg, if it is acted upon by a net force of 42 N.

pychu [463]

Answer:

7 m/s²

Explanation:

The formula for force is:

$f= m*a$

We want to find acceleration, so we must rearrange the formula for $a$ . Divide both sides of the equation by $m$

$\frac{f}{m}=\frac{m*a}{m}$

$\frac{f}{m}=a$

Acceleration can be found by dividing the force by the mass.

The force is 42 newtons and the mass is 6 kilograms. A newton is equal to 1 kg * m/s², therefore the force is 42 kg* m/s².

$f= 42 kg*m/s^2\\m=6 kg$

Substitute the values into the formula.

$a=\frac{f}{m}$

$a=\frac{42 kg*m/s^2}{6kg}$

Divide. When we divide, the kg in the numerator and denominator will cancel each other out.

$a=\frac{42}{6}m/s^2$

$a= 7 m/s^2$

The acceleration of the object is 7 meters per square seconds.

A spherical shell with a net charge of 3Q surrounds a point charge of -q at the center of the shell. The charges on the inner an

aleksley [76]

Answer:

1) The charge on the outer shell is +4·Q

2) The charge on the inner shell is +Q

Explanation:

1) The given parameters of the spherical shell are;

The net charge on the spherical shell = 3·Q

The point charge surrounded by the spherical shell = -Q

Let 'x' represent the charge on the outer shell, and let 'y', represent the charge on the inner shell, we have;

The net charge, 3·Q = -q + x

∴ x = 3·Q + Q = 4·Q

The charge on the outer shell, x = 4·Q

2) The net charge in the shell is zero, therefore, the charge on the inner shell, 'y', is given as follows;

-Q + y = 0

∴ y = +Q

The charge on the inner shell, y = +Q
