pentagon [3]3 years ago
8 0

Answer:

No, it is independent

Explanation:

As we know that car is moving horizontally

so the vertical component of the speed is zero initially

so in order to hit the ground we know that

\Delta y = v_y t + \frac{1}{2}at^2

so here we know that

h = 0 + \frac{1}{2}gt^2

on solving above equation for time

t = \sqrt{\frac{2h}{g}}

so we will say that it will not depends on the initial horizontal speed

In the diagram, q1 = -3.33*10^-9 C and
Anna [14]

Answer:

The distance will be "0.319 m".

Explanation:

The diagram of the given question is not attached with the problem. Below is the attached figure.

The given values are:

q1 = -3.33\times 10^{-9}  \C

q2 = -5.22\times 10^{-9} \ C

As we know,

The electric field will be equivalent as well as opposite throughout the direction, then

⇒ \frac{R.q1}{(0.255)^2} =\frac{R.q2}{r^2}

⇒ r^2=\frac{q2}{q1}\times (0.255)^2

By putting the values, we get

⇒      =\frac{-5.22\times 10^{-9}}{-3.33\times 10^{-9}}\times (0.255)^2

⇒      =1.568\times 0.065

⇒  r^2=0.10193

⇒  r=\sqrt{0.10193}

⇒     0.319 \ m

Your brother is insisting that you’ll never hear a sound produced behind a barrier wall at the end of your yard you notice that
Tresset [83]

Answer

D.Diffraction

Explanation

Diffraction is a property that is experienced by waves when they come across a barrier when they are in motion.

The ways tends to curve behind the barrier. This is called diffraction of waves.

Now, sound is a wave and it also experience diffraction. . So the brother will be able to hear the sound due to diffraction
