Answer:

A) A source of electrical energy.

Explanation:

The Symbol of two long lines, two short lines represents and, a positive and negative sign is a voltage source, which is a two-terminal device capable of maintaining a constant voltage.

The voltage generates an electric field, which makes the electrons inside the conductive cables to move along the circuit from the positive sign to the negative sign.

Determine the magnitude as well as direction of the electric field at point A, shown in the above figure. Given the value of k =
Pavlova-9 [17]

Answer:

The magnitude of the electric field is 8.99*10^{12}N/C in the r direction.

Explanation:

The equation of the electric field is given by:

|\vec{E}|=k\frac{q}{r^{2}}

Where:

  • k is the Coulomb constant is 8.99 *10^{9}\: Nm^{2}C^{-2}
  • q is the charge
  • r is the distance from A to q

|\vec{E}|=8.99*10^{9}\frac{12.5}{0.11^{2}}    

\vec{E}=9.29*10^{12} \vac{r} \: N/C

Therefore, the magnitude of the electric field is 8.99*10^{12}N/C in the r direction.

I hope it helps you!

A 20 g ball of clay traveling east at 3.5 m/s collides with a 35 g ball of clay traveling north at 2.0 m/s .
Elanso [62]

The movement direction of the resulting 55 g blob of clay 45o north of east  and the speed of the resulting 55 g blob of clay is 1.8 m/s.

Calculation:-

Let us consider the east direction as the positive X-direction and the north direction as the positive Y-direction.

Mass of the first ball of clay = m1 = 20 g = 0.02 kg

Mass of the second ball of clay = m2 = 35 g = 0.035 kg

Initial velocity of the first ball of clay = V1 = 3.5 m/s  to the east

Initial velocity of the second ball of clay = V2 = 2 m/s  to the north

Final velocity of the blob of clay = V3

X-component of the final velocity of the blob of clay = V3x

Y-component of the final velocity of the blob of clay = V3y

By conservation of linear momentum in the X-direction,

m1V1 = (m1 + m2)V3x

(0.02)(3.5) = (0.02 + 0.035)V3x

V3x = 1.273 m/s

By conservation of linear momentum in the Y-direction,

m2V2 = (m1 + m2)V3y

(0.035)(2) = (0.02 + 0.035)V3y

V3y = 1.273 m/s

V3 = 1.8 m/s

A) Movement direction of the resulting 55 g blob of clay = 45o north of east

B) Speed of the resulting 55 g blob of clay = 1.8 m/s

Mass, in physics, quantitative measure of inertia, a essential property of all count. it's miles, in effect, the resistance that a body of rely gives to a alternate in its pace or function upon the software of a pressure. The more the mass of a body, the smaller the alternate produced with the aid of an implemented pressure.
