What are the units of the following properties? Enter your answer as a sequence of five letters separated by commas, e.g., A,F,G
Marysya12 [62]

Answer:

The sequence is A,B,H,B,F

Explanation:

  • The Standard International unit is Kilogram (kg) and the mass of a body can also be expressed in gram (g).
  • Heat is a form of energy and the unit for energy is joule (J), thus the unit of heat is also joule (J).
  • Density is mass per unit volume where the unit of mass is gram (g) and the unit of volume can be taken as milli-liter (mL). Thus g/mL is the unit of density.
  • The unit of energy is joule (J).
  • Molarity is number of solute in mol dissolved in 1 liter of solution. Thus mol/L is the the unit of molarity.

A negatively-charged particle is slowly moving as it enters a region that has a constant magnetic field. If the velocity of the
Anna71 [15]

Answer:

no deflection and net force is zero. Moving in same direction and with same speed

Explanation:

Charge = negative

the angle between the velocity vector and the magnetic field vector is 0°, so the force is given by

F = q v B Sin 0

F = 0

As the force is zero so the charge particle moves with the same velocity and in the same direction.

there is no deflection in the path of negatively charged particle.

If the current in a wire is directed upward, what is the direction of the magnetic field produced by the current?
Valentin [98]

Answer:

B. counterclockwise

Explanation:

We can solve the problem by using the right-hand rule:

- put your thumb finger of the right hand in the same direction of the current in the wire (upward)

- wrap the other fingers around the thumb

- the direction of the other fingers will give the direction of the magnetic field lines

By doing these steps, we see that the other fingers form concentric circles in a counterclockwise direction (seen from above), so this is the direction of the magnetic field lines.
