Combined resistance of two resistors connected in parallel is 6Ω. One of the resistance is 12Ω . What will be the resistance of

the second resistor?
Physics
1 answer:
vodka [1.7K]3 years ago
8 0

Explanation:

Combined resistance = 1 / [1/12 + 1/x] = 6

1/12 + 1/x = 1/6

x = 12

The resistance of the 2nd resistor is 12Ω.

Describe a situation in which an electron will be affected by an external electric field but will not be affected by an external
irina [24]

Answer:

Explanation:

Situations in which an electron will be affected by an external electric field but will not be affected by an external magnetic field

a ) When an electron is stationary in the electric field and magnetic field , he will be affected by electric field but not by magnetic field. Magnetic field can exert force only on mobile charges.

b ) When the electron is moving parallel to electric field and magnetic field . In this case also electric field will  exert force on electron but magnetic field field will not exert force on electrons . Magnetic field can exert force only on the perpendicular component of the velocity of charged particles.

Situations when electron is affected by an external magnetic field but not by an external electric field

There is no such situation in which electric field will not affect an electron . It will always affect an electron .

At which point in the life cycle of a star does nuclear fusion begin?
Norma-Jean [14]
I would say B : main sequence is the answer . this is the answer i believe because the star will increase in size and than shine brightly and when it's done , it will get smaller turning into  nebula , eventually exploding sometime around the last stage , but not the last stage of b , c, or d

i really hope that this helps you a lot.

A pole-vaulter just clears the bar at 5.31 m and falls back to the ground. The change in the vaulter's potential energy during t
irina [24]

Answer:

Weight = 734.46 N

Explanation:

Given:

Initial height of the pole-vaulter is, h_i=5.31\ m

Final height of the pole-vaulter is, h_f=0\ m

Change in the vaulter's potential energy is, \Delta U=-3900\ J

We know that, change in potential energy is given as:

\Delta U=mg(h_f-h_i)

Where, 'm' is the mass of the object, 'g' is acceleration due to gravity and has a value of 9.8 m/s².

Now, weight of the object is given as the product of its mass and acceleration due to gravity. So, replace 'mg' by weight 'w'. So, the equation becomes,

\Delta U = w(h_f-h_i)

Now, rewriting in terms of 'w', we get:

w=\dfrac{\Delta U}{(h_f-h_i)}

Now, plug in all the given values and solve for 'w'. This gives,

w=\dfrac{-3900\ J}{(0-5.31)\ m}\\\\\\w=\dfrac{3900}{5.31}\ N\\\\\\w=734.46\ N

Therefore, weight of the vaulter is 734.46 N.
