What is the density of a substance of volume 3 m3and mass 9 kg?
butalik [34]

Answer:

Density = 3 kg/m³

Explanation:

Given the following data;

Volume = 3m³

Mass = 9 kg

To find the density;

Density can be defined as mass all over the volume of an object.

Simply stated, density is mass per unit volume of an object.

Mathematically, density is given by the formula;

Density = \frac{mass}{volume}

Substituting into the formula, we have;

Density = \frac{9}{3}

Density = 3 kg/m³

A force off 700 newtons is applied to a 600 kg bowling ball. What is the acceleration of the bowling ball once the force is appl
Readme [11.4K]

Answer:

<h2>1.17 m/s²</h2>

Explanation:

The acceleration of an object given it's mass and the force acting on it can be found by using the formula

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

f is the force

m is the mass

From the question we have

a =  \frac{700}{600}  =  \frac{7}{6}  \\  = 1.1666666...

We have the final answer as

<h3>1.17 m/s²</h3>

Hope this helps you

How much farther away from a current-carrying wire would you
disa [49]

Answer: Your question is open ended therefore i will provide a general answer based on the general concept of  your question.

Answer : At half distance between the center of the Magnetic field the magnetic pole the effect of the magnetic field generated will be half as strong

Explanation:

Magnetic force  ∝  1 / d^2

This simply means increase in the squared distance of an object leads to the decrease in the effect of the magnetic field generated by a current carrying wire.  

Hence ;  

At half distance between the center of the Magnetic field the magnetic pole, the effect of the magnetic field generated will be half as strong
