If Aldebaran were to explode tonight then we will be able to see this explosion on the Earth in approximately 65 years. A light-year is a distance that light travels in one (1) year.

A light-year can be defined as a unit equal to the distance that light needs to travels in one (1) year on the Earth.

One light-year can be considered as a unit that equates to approx. 9.7 trillion kilometers (km) or 5.9 trillion miles.

In consequence, a light-year is a distance unit instead of a unit of time, and this unit was developed by Otto Ule.

A spinning top (also called easily a top) is a specific toy that does not utilize the gyroscope effect during its movement.

The gyroscope effect refers to the characteristic that allows an object to maintain a constant direction of axis rotation when it is rotating.

This effect (gyroscope effect) mainly depends on the velocity of the object and its direction.

The gyroscope effect is exploited by many applications such as in missiles or satellites when they are in orbit.

Answer: 28.71 km

Explanation:

For the convex mirror (ocean):

Radius of curvature = 6.4*10^3 km

Focal length (f) = R/2 = 3.2*10^3 km

Object distance (u) = -3.84*10^5

Mirror formula: [tex]\frac{1}{u} + \frac{1}{v} = \frac{1}{f}[/tex]

[tex]\frac{1}{u} + \frac{1}{v} = \frac{1}{f}[/tex]

[tex]\frac{-1}{3.84*10^5} + \frac{1}{v} = \frac{1}{3.2*10^3}[/tex]

v = 3173.55km

Magnification, [tex]m = \frac{-v}{u} = \frac{-3173.55}{-3.84*10^5} = \frac{h_{i} }{h_{o} }[/tex]

So, height of image/height of object = 3173.55/3.84*10^5

Diameter of image = 3173.55/3.84*10^5 * 3475

Diameter of image = 28.71 km

Therefore, the diameter of the image is 28.71 km

Answer:

1 kw-hr = 1000 w * 3600 sec = 3.6E6 Joules

E = P t = 120 J/C * 8 C/sec * 3600 sec /hr * 15 hr =   5.18E7Joules

where E is energy used by microwave

5.18E7 / 3.6E6 * .11 = $1.58    cost to run for 15 hrs

The electric potential energy of a charge that experiences a force of 3. 6 × 10⁻⁴ N when it is 9. 8 × 10⁺⁵m from the source of the electric field will be 3.528×10⁻⁸ V.

Electric potential energy is the amount of work needed to move a unit charge from a point to a specific point against an electric field.

The given data in the problem is;

F is the electric force= 3. 6 × 10⁻⁴ N

V is the electric potential=?

d is the distance = 9. 8 × 10⁻⁵ m

The electric potential energy is given as the product of the electric force and distance.

V=Fd

V = 3.6×10⁻⁴ ×( 9.8×10⁻⁵)

V = 3.528×10⁻⁸ V.

Hence the electric potential energy of a charge will be 3.528×10⁻⁸ V.

Option C is correct. The image is located between F and the center of the lens, on the other side of the lens the upright than the actual object.

Virtual and imaginary image is the type of upright image. A virtual picture is generated when light rays appear to meet at a certain spot following reflection from a mirror.

The picture that appears right-side-up is called an erect image. Unlike a virtual image, it is created by the real junction of light beams.

The lens in the illustration is a concave lens. The light rays that fall from the item onto the lens diverge, making it a diverging lens.

The item is held between the focus and the lens's center. At the same side of the item, an image would form between the focus and the lens's center.

The picture would be simulated, shrunk, and centered. As a result, the correct answer is: "The picture is upright."

Hence option C is correct

The displacement of the cyclist from point A to B is 39.3 m.

The displacement of the cyclist is equal to the change between the final position and initial position of the cyclist. This can also be described as the shortest distance between two positions.

From the given image, the displacement of the cyclist from point A to B can be determined by formula for calculating length of arc,

D = (θ/360) x 2πr

D = (90/360) x 2π x 25

D = 39.3 m

Thus, the displacement of the cyclist from point A to B is 39.3 m.
