EVERYTHING electrical that we do in the real world ... positive and negative electric charges, static electricity, positive and negative electric current, lightning traveling up or down ... is ALL done with particles of NEGATIVE charge, called electrons.

== When you pile on extra electrons, you have a negative static charge.

== When you strip electrons away, you leave a positive static charge.

== When you make electrons flow through something, you have electric current.  If it flows one way, it's called positive current.  If it flows the other way, it's called negative current.  But it's always electrons (negative charges) that are flowing from place to place.

A distance-time graph indicates that an object moves 20 m in 10 s and then remains at rest for 20s. What is the average speed of
boyakko [2]

Answer:

v = 2 m/s

Explanation:

The object moves 20 m in 10 s initially. Then it remains at rest for 20 s. It is required to find the average speed of the object.

Fro 10 s it covers 20 m. For that time, speed is :

v=\dfrac{d}{t}\\\\v=\dfrac{20\ m}{10\ s}\\\\v=2\ m/s

For 20 s, it was at rest means distance covered is 0. So, speed is 0.

The average speed of the object is equal to the sum of speed for 10 s and for 20 s i.e.

v = 2 m/s + 0 = 2 m/s

So, the average speed of the object is 2 m/s.

MAXImum [283]
This is a riddle meant to have a humorous effect.
So, what did they call the bug that the astronauts brought back from the moon? - A lunatic.

If a stress of 1.05 × 107 n/m2 is applied to his ligament, how much will it stretch? the young\'s modulus for the acl is 1.10 ×
Ainat [17]

As we know that

Young's\: Modulus = \frac{stress}{strain}

here we know that

Young's Modulus = 1.10 \times 10^8

stress = 1.05 \times 10^7

now by the above formula we will have

1.10 \times 10^8 = \frac{1.05 \times 10^7}{strain}

strain = \frac{1.05 \times 10^7}{1.10 \times 10^8}

strain = 0.095

Two point sources are vibrating in phase producing two-dimensional water wave interference. The first antinodal line on either s
Viktor [21]

For all antinodal positions we know that

\Delta \phi = 2N\pi

now we also know the relation between phase difference and path difference

\Delta \phi = \frac{2\pi}{\lambda}\Delta x

now we will have

2N\pi = \frac{2\pi}{\lambda}\Delta x

now from above equation we will have

\Delta x = N\lambda

now for the first anti node position

N = 1

\Delta x = \lambda

Option D is correct
