Answer:

The most significant difference between the static and current electricity is that in static electricity the charges are at rest and they are accumulating on the surface of the insulator. Whereas in current electricity the electrons are moving inside the conductor.

Answer:

Static electricity is electricity that does not flow. It is produced by electrons rubbing off one object and being collected on another. It cannot flow through a wire like the electricity in your home. An example of static electricity is rubbing your hair on a balloon. static electricity causes your hair to stick up. On the other hand, current electricity can flow. It is generated by batteries and power plants. In current electricity the electrons are moving inside the conductor. Current electricity runs through circuits. These circuits run all around your homes. Current electricity is also what we use in our homes. An example of current electricity is the electricity that we use from outlets.

A 5 cm radius isolated conducting sphere is charged so its potential is 100 V, relative to the potential far away. The charge de

MArishka [77]

The electric potential (V) produced by a point charge with a charge of magnitude Q, at a point a distance r away from the point charge, is given by the equation:

$V = \frac{kQ}{r}$

Here,

k = Coulomb's constant

Q = Charge

r = Distance

If we rearrange the equation to find the distance we have,

$Q=\frac{Vr}{k}$

$Q = \frac{(100)(5*10^{-2})}{9*10^9}$

$Q = 5.55*10^{-10} C$

Now the value of the charge density is equivalent to the charge on the surface area of the sphere this is

$\gamma = \frac{Q}{A_s}$

$\gamma = \frac{Q}{4\pi r^2}$

$\gamma = \frac{ 5.55*10^{-10}}{4\pi (5*10^{-2})^2}$

$\gamma = 1.76*10^{-8} C/m^2$

Anettt [7]

Answer:

Combined speed, V = 2 m/s

Explanation:

Given that,

Mass of object 1, m = 5 kg

Speed of object 1, u = 4 m/s (due right)

Mass of object 2, m' = 2 kg

Speed of object 2, u' = -3 m/s (due left)

<em>Let V is the speed of the objects after the collision. Here, both objects stick to each other. Therefore, the momentum remains conserved. So,</em>

$mu+m'u'=(m+m')V\\\\V=\dfrac{mu+m'u'}{(m+m')}\\\\V=\dfrac{5\times 4+2\times (-3)}{(5+2)}\\\\V=2\ m/s$

So, the combined speed of the masses will be 2 m/s.

What is the force on a 250 kg elevator that is falling freely at 9.8 m/sec2?

Viefleur [7K]

Answer:

Since it is falling freely, the only force on it is its weight, w.

w = m × g = 250 kg × 9.8 m/s^2 = 2450 Newton/N
