Explanation:

<u>Nuclear Energy Production </u>

Nuclear energy is produced by splitting uranium atoms in a process called fission. This generates heat and it's managed to produce steam, which later is used by a turbine generator to generate electricity. The heat must be taken out of the system, so a cooling process, usually involving water is the final step.

Because nuclear power plants don't burn fuel, they are known as clean energy sources.

A ray diagram is shown.

Svetlanka [38]

Answer:

It is virtual and behind the mirror

Explanation:

When an image is produced by a mirror, we have the following situations:

- The image is said to be in front of the mirror if it is on the same side of the object, with respect to the mirror

- The image is said to be behind of the mirror if it is on the opposite side of the object, with respect to the mirror

Moreover:

- The image is said to be real if it is in front of the mirror

- The image is said to be virtual if it is behind the mirror

In this case, the image (located at point I) is on the opposite side of the object (located at point O), so it is virtual and behind the mirror.

The radioactive element polonium decays according to the law given below where Q0 is the initial amount and the time t is measur

kogti [31]

Answer:

1280 mg

Explanation:

Radioactive decay is a phenomenon that occurs when a certain isotope of an element, said to be radioactive, decays, turning into a lighter nucleus and emitting radiation + energy in the process.

The radioactive decay of this isotope of polonium is described by the equation

$Q(t)=Q_0 2^{-\frac{t}{140}}$

where

$Q(t)$ is the amount of polonium left after time t

$Q_0$ is the amount of polonium t time t = 0

$140$ is the half-life of the polonium, in days (it is the time it takes for the initial element to halve its amount)

IN this problem, we know that:

After t = 560 days, the amount of polonium left is $Q(t)=80 mg$ . Therefore, we can re-arrange the equation, substituting t = 560 d, and solve for $Q_0$ to find the initial amount of polonium:

$Q_0 = Q(t) \cdot 2^{\frac{t}{140}}=(80)\cdot 2^{\frac{560}{140}}=1280 mg$

A 10 kg box slides down a lane inclined at an angle θ = 30 . The plane has a friction of coefficient 0.1. The box starts from th

g100num [7]

Answer:

The distance the box traveled down the plane is 19.28 m

Explanation:

The angle of repose, α, is given by the relation;

tan⁻¹(μ) = α

tan⁻¹(0.1) = 5.7°

Therefore, we have;

M·g·sin(θ) - μ·N = M·a

Where:

M = Mass of the box = 10 kg

g = Acceleration due to gravity = 9.81 m/s²

θ = Angle of inclination of the plane = 30°°

μ = Coefficient of friction = 0.1

a = Acceleration of the box along the incline plane

N = Normal force due to the weight of the box = M·g·cos(θ)

10 × 9.81 × sin30 - 0.1 × 9.81 × cos(30) = 10 × a

48.2 = 10 ×a

a = 48.2/10 = 4.82 m/s²

The distance, s, traveled by the box is given by the relation;

s = u·t + 1/2×a·t²

Where:

u = Initial velocity = 0 m/s

t = Time of motion = 2.0 s

∴ s = 0×2 + 1/2 × 4.8 × 2² = 19.28 m

The box traveled 19.28 m down the plane.
