What’s the right one.

Physics
1 answer:
Allushta [10]3 years ago
7 0

Answer:

J would be your best answer.

Explanation:

The closer the objects are to the charge, the greater the force. Granted, it entirely depends, and would not always be a linear line. Chances are, it would look more like answer choice G. However, note that Answer G does not start the greatest magnetic force at 0, which is where the strongest magnet force will be. The farther the object is, the weaker the force, which explains the downward trend.

How electromagnet works in circuit breaker
Svetradugi [14.3K]

Explanation:

A circuit breaker is an automatic switch that cut off current in a circuit when the current become too large. When the current in a circuit increases, the strength of the electromagnet will increase in accordance; this will pull the soft iron armature towards the electromagnet.

Can someone explain it with steps?
Anton [14]

Answer:

Option C is the correct answer

Explanation:

Distance travelled by car during reaction time

=15\times0.4\\\\=6m

The car stopped before hitting the animal by 1 m

Distance travelled during deceleration is 21-6-1=14m

Hence by v^2=u^2+2as

We have

0^2=15^2+2 \cdot a \cdot 14\\\\a=\frac{-225}{28} \\\\=-8.03m/s^2

Option C is the correct answer

A certain parallel-plate capacitor is filled with a dielectric for which Κ = 5.5 .The area of each plate is 0.034 m2 , and the p
Nesterboy [21]

Answer:

The maximum energy that can be stored in the capacitor is  6.62 x 10⁻⁵ J

Explanation:

Given that,

dielectric constant k = 5.5

the area of each plate, A = 0.034 m²

separating distance, d =  2.0 mm = 2 x 10⁻³ m

magnitude of the electric field =  200 kN/C

Capacitance of the capacitor is calculated as follows;

C = \frac{k \epsilon A}{d} = \frac{5.5*8.85*10^{-12}*0.034}{2*10^{-3}} = 8.275 *10^{-10} \ F

Maximum potential difference:

V = E x d

V = 200000 x 2 x 10⁻³ = 400 V

Maximum energy that can be stored in the capacitor:

E = ¹/₂CV²

E = ¹/₂ x 8.275 x 10⁻¹⁰ x (400)²

E = 6.62 x 10⁻⁵ J

Therefore, the maximum energy that can be stored in the capacitor is  6.62 x 10⁻⁵ J
