<span>Hurricanes are formed due to D. Warming oceans
The heat that collected by atmosphere will create a difference in pressure and gathered air mass within a certain area. When this happen on land, it may only resulted in a strong wind, but If this happen on top of ocean it will carry water that leading up to hurricanes.</span>

A thin conducting square plate 1.0 m on the side is given a charge of-2.0 x 10-6 c. A proton is placed 1.0 en above the center o

adell [148]

Answer:

Acceleration, $a=1.08\times 10^{13}\ m/s^2$

Explanation:

It is given that,

Side of the square plate, l = 1 m

Charge on the square plate, $Q=-2\times 10^{-6}\ C$

Position of a proton, x = 1 cm

The electric field due to a parallel plate is given by :

$E=\dfrac{Q}{2A\epsilon_o}$

Electric force is given by :

F = q E

$F=\dfrac{Qe}{2A\epsilon_o}$

e is the charge on electron

The acceleration of the proton can be calculated as :

$a=\dfrac{F}{m}$

m is the mass of proton

$a=\dfrac{Qe}{2A\epsilon_o m}$

$a=\dfrac{2\times 10^{-6}\times 1.6\times 10^{-19}}{2(1)^2\times 8.85\times 10^{-12}\times {1.67\times 10^{-27}}}$

$a=1.08\times 10^{13}\ m/s^2$

So, the acceleration of the proton is $1.08\times 10^{13}\ m/s^2$ . Hence, this is the required solution.

What quantity do units represent in a value?

mihalych1998 [28]

Answer : Magnitude

Explanation :

In a value, the magnitude is represented by its units. It can be adopted by convention or by law.

Magnitude of any unit is used to measure the same kind of quantity.

For example: The unit of length which is a physical quantity is meter (m).

So, magnitude is correct answer.

In an experiment, an object is released from rest from the top of a building. Its speed is measured as it reaches a point that i

NikAS [45]

Answer:

so the speed will increase by 1.44 times then the initial speed if the distance is increased to double

Explanation:

As we know that the air friction or resistance due to air is neglected then we can use the equation of kinematics here

$v_f^2 - v_i^2 = 2 a d$

since we released it from rest so we have

$v_i = 0$

so here we have

$v_f = \sqrt{2gd}$

now if the distance is double then we have

$v_f' = \sqrt{2g(2d)}$

now from above two equations we can say that

$v_f' = \sqrt2 v_f$

so the speed will increase by 1.44 times then the initial speed if the distance is increased to double
