Answer:

they are,

1. scissor = they are very useful for cutting papers, clothes, etc. if there wouldn't be sicssor than we would not be able to cut various things . it has made easier to cut tgings.

2. nailcutter= it is also one type of simple machine. it is used to trim our nails. if there would be no nailcutter then our nail would be so dirty and long.

hope it helps..

Harman [31]

The calculated time is 6 seconds.

Time is defined by physicists as the flow of events from the past through the present and into the future. In essence, a system is timeless if it is unchanging. When describing events that take place in three-dimensional space, time can be thought of as the fourth dimension of reality. Even if time isn't directly connected to energy, it is undoubtedly connected to many other components of energy. For instance, the movement of energy across the universe can affect the direction of time (from the past to the future).

V= 2 m/s

d=12 m

t=?

we know that velocity=displacement / time

time= displacement / velocity

= 12/2

=6 seconds

the calculated time is 6 seconds.

Q|C A string with linear density 0.500 g/m is held under tension 20.0 N. As a transverse sinusoidal wave propagates on the strin

julia-pushkina [17]

A string with linear density 0.500 g/m.

Tension 20.0 N.

The maximum speed $v_{y, max}$

The energy contained in a section of string 3.00 m long as a function of $v_{y, max}$ .

We are given following data for string with linear density held under tension :

μ = 0.5 $\frac{g}{m}$

= 0.5 x 10⁻³ $\frac{kg}{m}$

T = 20 N

If string is L = 3m long, total energy as a function of $v_{y, max}$ is given by:

E = 1/2 x μ x L x ω² x A²

= 1/2 x μ x L x $v^{2} _{y, max}$

= 7.5 x 10⁻⁴ $v^{2} _{y, max}$

So, The total energy as a function of $v^{2} _{y, max}$ = 7.5 x 10⁻⁴ $v^{2} _{y, max}$

What must be the distance (in meters) between a point charge q1 = 16 μC and a point charge q2 = 32 μC for the electrostatic forc

adoni [48]

Answer:

d = 0.71 meters

Explanation:

It is given that,

Charge 1, $q_1=16\ \mu C=16\times 10^{-6}\ C$

Charge 2, $q_2=32\ \mu C=32\times 10^{-6}\ C$

Electrostatic force between charges, F = 9 N

Let d is the distance between the charges. The electrostatic force between the charges is given by the product of charges and divided by square of distance between them. Mathematically, it is given by :

$F=k\dfrac{q_1q_2}{d^2}$

$d=\sqrt{\dfrac{kq_1q_2}{F}}$

$d=\sqrt{\dfrac{9\times 10^9\times 16\times 10^{-6}\times 32\times 10^{-6}}{9}}$

d = 0.71 meters

So, the distance between the charges is 0.71 meters. Hence, this is the required solution.
