Answer:

One has 1E6 km^2 / MM

4E6 km^2 / (1E6 km^2/MM) = 4 MM or 4 megameter

In 4000,000 square kilometers, there are 4 square megameters if the one square megameter is equal to 1. 0×106 square kilometers.

It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.

We have:

One square megameter = [tex]1\times10^6[/tex]

Let's suppose the x square megameters in the 4,000,000 square kilometers

Then x can be found as follows:

[tex]\rm x = \frac{4,000,000}{1\times10^6}[/tex]

x = 4 square megamters

Thus, in 4000,000 square kilometers, there are 4 square megameters if the one square megameter is equal to 1. 0×106 square kilometers.

Hi there!

Recall the equation for angular momentum:
[tex]L = I\omega[/tex]

L = Angular momentum (kgm²/s)
I = Moment of Inertia (kgm²)
ω = angular velocity (rad/s)

We know that the Moment of Inertia of a solid cylinder is equivalent to:
[tex]I = \frac{1}{2}MR^2[/tex]

M = mass (kg)
R = radius (m)

Plug in the givens to solve for the moment of inertia. Remember to divide the diameter by 2 for the radius, and to convert to meters.

[tex]r = \frac{d}{2} = 20/2 = 10 cm \\\\10 cm = 0.1 m[/tex]

[tex]I = \frac{1}{2}M(0.1^2) = 0.005 M[/tex]

We can rearrange the equation of angular momentum to solve for mass.

[tex]L = 0.005M * \omega\\\\\frac{L}{0.005 \omega} = M \\\\M = \frac{2}{0.005(10)} = \boxed{ 40 kg}[/tex]

Answer:

option d

it was converted into chemical energy stored in the sugar

Answer:

D. It was converted into chemical energy stored in the sugar.

Explanation:

A. It was produced by the plant. This is false because light energy is a reactant and not a product formed by the plant.

B. It was changed into oxygen gas. This is false because light energy could not be transformed to oxygen gas by any chemical means. Instead, carbon dioxide leads to oxygen being produced by the plant.

C. It was destroyed during the chemical reaction. This is false, it cannot be destroyed during the chemical reaction. Instead, it was used up and converted into chemical energy stored in the sugar.

The object's velocity accelerating from rest from the applied force and time is closest to 4 m/s.

The velocity of the object can be determied by applying Newton's second law of motion as shown below;

F = ma

where;

The acceleration of the object is calculated as follows;

a = F/m

at time, t 4.0 s, the corresponding force = 2 N

a = 2/2

a = 1 m/s²

Velocity of the object is calculated as;

v = u + at

v = 0 + 1 x 4

v = 4 m/s

The maximum mass of coal that the barge will carry in freshwater without sinking is 0.111 kg.

The volume of the barge is calculated as follows;

V = L³

V = (4.8 cm)³

V = 110.6 cm³

For the barge to float in freshwater, its density must be less or equal to density of water.

density(barge) = density(water)

density(barge) = 1 g/cm³

mass = density x volume

mass = 1 g/cm³ x 110.6 cm³

mass = 110.6 g

mass = 0.111 kg

Thus, the maximum mass of coal that the barge will carry in freshwater without sinking is 0.111 kg.

The reflected ray of a ray of light that makes an angle of 25° with the normal to a plane mirror and its is turned through 60°, making the angle of incidence to be 31° is rotated through 12°.

Freflection can be defined as the turning back of a ray of light when its strikes a plane's surface.

There are 2 laws of reflection

(1) The first law of reflection states that the incident ray the reflected ray and the normal all at the point of incidence lie in the same plane

(2) The second law of reflection states that the angle of incident is equal to the angle of reflection.

From the question, if the incidence ray is rotated through 6°, then the  reflected ray is rotated through 12°

Hence, The reflected ray is rotated through 12°.

The reflection resulting in a 31° angle of incidence and the angle is the reflected ray rotated will be 12°

The law of reflection specifies that upon reflection from a downy surface, the slope of the reflected ray is similar to the slope of the incident ray.

The reflected ray is consistently in the plane determined by the incident ray and perpendicular to the surface at the point of reference of the incident ray.

When the light rays descend on the smooth surface, the angle of reflection is similar to the angle of incidence, also the incident ray, the reflected ray, and the normal to the surface all lie in a similar plane.

As a result, the reflected light is rotated by 12°.

The time taken for the charge to pass through the cross-section of the wire is 6.0s.

Given the data in the question;

Current; [tex]I = 5.0A[/tex]

Charge; [tex]Q = 30C[/tex]

Time; [tex]t = \ ?[/tex]

Current is simply the rate of flow of charged particles i.e electrons caused by EMF or voltage.

If a charge passes through the cross-section of a conductor in a given time, the current I is expressed as;

[tex]I = \frac{Q}{t}[/tex]

Where Q is the charge and t is time elapsed.

We substitute our given values into the expression above to determine the time it took the charge to pass through this wire.

[tex]I = \frac{Q}{t}\\ \\5.0A = \frac{30C}{t} \\\\t = \frac{30C}{5.0A} \\\\t = 6.0s[/tex]

Therefore, the time taken for the charge to pass through the cross-section of the wire is 6.0s.
