So, the first question is: how many meters are 10 nm?

1nm =<span>0.000000001 m.

So 10 nanometers are </span><span>0.00000001 m!

Now, how many milimeter are those?
let's start with meters, 1 meter are 1000 milimeters.
so </span>
0.00000001*1000=0.<span><span>00001</span> m!

now, micrometers .1 micrometer are 1000 nanometers.
so 10 nanometers are 0.01 micrometers! (1 nanometer is 0.001 micrometers)

Peter does 3,000 joules (J) of work by moving an object 40 meters (m). What is the force that Peter applies to the object? A 75
Papessa [141]

The force that peter applies to the object of distance 40m is 75N.

<h3>HOW TO CALCULATE FORCE</h3>

The force applied to an object can be calculated by dividing the work done on the object by the distance moved. That is;

Force = Work done ÷ distance

According to this question, the work done is 3000 joules while the distance moved is 40m. The force is calculated as follows:

Force = 3000J ÷ 40m

Force = 75N

Therefore, the force that peter applies to the object of distance 40m is 75N.

Unbalanced force acting on a body may not change the dimension and balanced forces many change the dimension. JUSTIFY. Please he
Rainbow [258]

If the body is in motion, the force operating on it simply produces the motion; however, if the force acting on it is balanced, the body is in a static position and its shape is flexible.

<h3>What is force?</h3>

Force is defined as the push or pulls applied to the body. Sometimes it is used to change the shape, size, and direction of the body.

Force is explained as the multiplication of mass and acceleration. Its unit is N.

It is the external agent which helps to change the shape and size of an object. Force is used to pushing and pull the object and sometimes changes the direction of motion.

The net force acting on an object is equal to the sum of all forces acting upon it.

F = F1 + F2 + F3

The force is found as;

F=ma

Where,

Force, F

Mass,m

Acceleration,a

Unbalanced forces operating on a body might not modify its dimension, but balanced forces might.

The unbalanced forces act on the body is helps to give the motion to the body and only one application of force can act on the object.

If there is motion in the body the force acting on the body causes only the motion but if the force acting on the body is balanced the body is in static condition and the shape of the body can change.

Hence the given statement is justified unbalanced force acting on a body may not change the dimension and balanced forces may change the dimension.

A solid sphere of radius 30cm is uniformly charged to 100nC. a) What is the volume charge density of the sphere? b) What is the
g100num [7]

Answer

given,

total charge Q = 100 n C

                        = 100 × 10⁻⁹ C

radius of the solid sphere = 30 cm

                                           = 0.3 m

Volume of sphere = \dfrac{4}{3}\pi r^3

                              = \dfrac{4}{3}\pi\times 0.3^3

                              =0.113 m³

a) volume charge density

\rho = \dfrac{10^{-7}}{0.133}

         ρ  = 8.85 × 10⁻⁷ C/m³

b) at r = 10 cm = 0.1 m

charge in the sphere at radius

Q = \dfrac{4}{3}\pi\times 0.1^3\time \rho

   = 3.7037 \times 10^{-9}C[/tex]

Field strength

E_1 = \dfrac{Q}{4\pi \epsilon_0 r^2}

E_1 = \dfrac{3.7037 \times 10^{-9}}{4\pi \times 8.85\times 10^{-12}\times 0.1^2}

      = 3.33 \times 10^3 N/C

at r = 20 cm = 0.2 m

Q = \dfrac{4}{3}\pi\times r^3\time \rho

E_1 = \dfrac{Q}{4\pi \epsilon_0 r^2}

E_1 = \dfrac{ \dfrac{4}{3}\pi\times r^3\time \rho}{4\pi \epsilon_0 r^2}

E_1 = \dfrac{\rho}{3 \epsilon_0}

E_1 = \dfrac{0.2\times 8.842 \times 10^{-7}}{3 \times 8.85\times 10^{-12}}

      = 6.66 \times 10^3 N/C

at r = 30 cm

E_1 = \dfrac{\rho}{3 \epsilon_0}

E_1 = \dfrac{0.3\times 8.842 \times 10^{-7}}{3 \times 8.85\times 10^{-12}}

      = 9.99 N/C
