Answer:

the flow is the same on both surfaces

Explanation:

Gauss's law says that the electric field flow through a Gaussian surface is equal to the charge inside the surface divided by the electric permittivity constant, the equation is

          Φ =∫ E . dA = q / ε₀

The point is the scalar product and the bold ones indicate vector,

Let us examine the situations that give us, the elective field is uniform so that the field lines that cross the surface of the square are constant and perpendicular to two sides, therefore in flow on one side it is equal to the flow on the other side, but of negative sign; so the net flow is zero, in the two sides there are 90º between the field lines and the normal to the surface (dA) so the flow is zero

Now let's analyze the circular surface in this case the angles between the field that is uniform, lines are parallel, and the normal circle changes at each point, but by the symmetry of the circle the angle that there is an area at the top is the same of the surface at the bottom connected by a diameter, the net flow in each pair of points is canceled and consequently in flow throughout the circle is zero.

  We can also see the same result if we see that within each surface there are no charges, so the right of the Zero Gas Law

From the above described the two surfaces have zero flow

Answer:

2874.33 m/s²

Explanation:

t = Time taken

u = Initial velocity

v = Final velocity

s = Displacement

a = Acceleration

g = Acceleration due to gravity = 9.81 m/s²

v^2-u^2=2as\\\Rightarrow a=\frac{v^2-u^2}{2s}\\\Rightarrow a=\frac{v^2-0^2}{2\times h}\\\Rightarrow v^2=2ah\ m/s

Now H-h = 0.588 - 0.002 = 0.586 m

The final velocity will be the initial velocity

v^2-u^2=2as\\\Rightarrow 0^2-u^2=2gs\\\Rightarrow -2ah=2\times g(H-h)\\\Rightarrow -2a0.002=2\times g0.586\\\Rightarrow a=-\frac{0.586\times -9.81}{0.002}\\\Rightarrow a=2874.33\ m/s^2

Acceleration of the frog is 2874.33 m/s²

Strength of electromagnets
Triss [41]

Lines of Force around an Electromagnet. ... The magnetic field strength of an electromagnet is therefore determined by the ampere turns of the coil with the more turns of wire in the coil the greater will be the strength of the magnetic field.

Each time the heart beats,what does it do to the blood
Tom [10]
Your blood runs through your blood stream, every vein in your body. without that heartbeat the blood would not make it to the required places it needs to run to and you will lose oxygen and parts of your body and organs will shut down.

What is simple machine<br>​
notsponge [240]

Answer:

ϟ \huge{ \boxed{ \purple{ \text{Simple \: Machine}}}}

⤥ We use different types of devices in our life to make our work easier. A spade is used to dig , a broom is used to sweep , a hammer is used to pass a nail on the wall and a plank is used to drag a load up to a certain height. All these simple things or devices , which are used in our daily life are called simple machines. Such simple machines do not do our work themselves but we have to use force on them to work with them. Thus , Simple machines are those tools or devices which make our work easier and convenient to do in the direction of force.

Hope I helped ! ッ

Have a wonderful day / night ♡
