Because it’s a product of two more basic units. The basic unit of area is the cubic meter for volume. By derived unit it refers to any given quantity which cannot be measured directly.

A derived unit is called so because it is the product of two more basic units. The basic unit of area is the cubic meter (m³) for volume. By derived unit, it refers to any given quantity which cannot be measured directly with any device.

A dipole of moment 0.5 e·nm is placed in a uniform electric field with a magnitude of 8 times 104 N/C. What is the magnitude of
Over [174]

Answer:

The net torque is zero

Explanation:

Let's assume that the dipole is compose of two equal but oposite charges e, and it cam be represented by a rod with one end having a charge e and the other end with a charge of -e. Notice that the dipole is parallel to the electric field thus the force felt by both of the charges will be parallel to the electric field. This means that there will be no components of the forces that are perpendicular to the rod which is a requirement for it to have a torque.

Identify the areas on the image where the force of repulsion is the least.​
aalyn [17]

Answer:

The central blue square in between the lower pair of magnet has the least force of repulsion.

Explanation:

We can explain this using the dual nature of magnets.

Each magnet must have two poles namely:

-North pole

-South pole

We assume that the magnetic lines of forces enters from south pole and leaves from the north pole.

When brought together, like poles repel each other while opposite poles attract each other.

In the picture, the lower two magnets have opposite poles facing each other, hence the force of repulsion is minimum there and the force of attraction is maximum.

Three identical resistors have an equivalent resistance 15.6 ohm when they are connected in series. What is the resistance for e
attashe74 [19]

Answer:

R=5.2\ \Omega

Explanation:

In series combination, the equivalent resistance is given by :

R_{eq}=R_1+R_2+R_3+...

Let the identical resistors be R. We have, R_{eq}=15.6\ \Omega

So,

R+R+R=15.6\\\\3R=15.6\\\\R=\dfrac{15.6}{3}\\\\R=5.2\ \Omega

So, the resistance of each resistor is 5.2\ \Omega.

Does mechanical advantage have units? Explain your answer.
motikmotik

Answer:

The mechanical advantage of a machine is the ratio of the load (the resistance overcome by a machine) to the effort (the force applied). For an ideal (without friction) mechanism, it is also equal to: There is no unit for mechanical advantages since the unit for both input and output forces cancel out.
