Basile [38]3 years ago
3 0
A). m/s ... meters per second. 
                 That's a speed.

b). m/s² ... (meters per second) per second. 
                   Acceleration
.

c). m²/s ... square meters per second.
                 Rate of change of area.
                 Meaningless unit, unless you happen to be
                     a painter of houses or a mower of lawns.

d). kg-m/s² ... (mass) x (an acceleration). 
                      This is a unit of force.  
                       In fact, it's the definition of "newton".

The moon orbiting the Earth

Explanation:

The motion of the moon orbiting the earth is a circular motion. Circular motion is simply the motion of an object in circle at constant speed.

  • A cannonball flying from a cannon is a projectile motion and not a circular motion.
  • A car moving along a straight track is a linear/translational motion.
  • Pendulum of a grandfather clock is a simple harmonic motion.

An infinite sheet carries a uniform, positive charge per unit area. The electric field produced by the sheet is represented by p
nexus9112 [7]

Complete Question

An infinite sheet carries a uniform, positive charge per unit area. The electric field produced by the sheet is represented by parallel lines drawn with a density N lines per m2 that are perpendicular to and away from the sheet. The charge per unit area on the sheet is doubled. How should the density of the electric field lines be changed?

A It should stay the same

B  It should be quadrupled.

C It should be quintupled

D It should be doubled.

E It should be tripled

Answer:

Option D is the correct option

Explanation:

Generally electric field is mathematically represented as

        E =  \frac{\sigma}{\epsilon_o}

Where \sigma is the charge per unit area (Charge density )

From the question we are told that \sigma is doubled hence the

     E =  \frac{2 \sigma }{\epsilon_o}    

Looking the equation above we see that the value of the electric field will also double given that it is directly proportional to the charge density
