Answer:
93 V
Explanation:
use the expression for induced emf as
EMF = L dI/dt
L = 560 x 10⁻³
dI = 2.5 A
dt = 0.015 s = 15 x 10⁻³ s
EMF = L dI/dt
= 0.560 * 2.5/0.015
= 93.33 V
≅ 93 V
Answer: It is the color of the container
Explanation:
The red at the bottom is the color of the bottom of the container. It is not part of the experiment and is not liquid.
The red liquid that is part of the experiment does indeed have the lowest density of the liquids which is why it is floating at the top of al the liquids with the only thing floating on top of it being the blue cube which has a lower density than it.
The car will halt at a minimum distance of 98.57 meters on a rainy day having a friction coefficient of 0.109.
Calculation of the minimum distance-
Provided that :
- the speed of the car = 52 km/h
= 52 x 0.278 m/s = 14.45 m/s
- Friction coefficient, μ = 0.109
the regular force exerted on the car,
Along X-direction, the force is
Friction acts in the opposite way along the x-axis
⇒-μ
⇒-μmg = 
⇒
μg
Utilizing the motion equation-
v² = u²+ 2 .a. s
The final speed, v=0 m/s
⇒0² = (14.45)² - 2 μg .s
⇒2 * 0.109 *9.8 *s = (14.45)² = 208.8
⇒s = 208.8 / 2.14 = 97.57 m
It is concluded that the car will halt at a minimum distance of 98.57 meters.

Answer:
The Sun is a celestial body. It's a massive, spinning orb of heated gas that's glowing. The Sun is similar to the stars that may be seen in the night sky. The Sun is the centre of our Solar System, containing the majority of its mass. The Sun is the centre of our Solar System, and all of the planets, including Earth, revolve around it.
Explanation:
A white dwarf cannot support its own weight by its degenerate pressure if its mass is greater than 1.4 solar masses.
<h3>
What are white dwarfs?</h3>
White dwarfs are stellar core remnant composed mostly of electron-degenerate matter.
White dwarf is very dense due to its large mass and smaller volume.
<h3>Reasons for comparable mass of white dwarfs and Sun</h3>
- Stars with main sequence masses less than about 0.5 solar masses cannot ignite the helium fusion required to become white dwarfs.
- A white dwarf cannot support its own weight by its degenerate pressure if its mass is greater than 1.4 solar masses.
