Explanation:

seasons are cause by the tilt in the Earths axis of rotation as it revolves around the sun.

Answer:

Frequency is the number of revolutions done per second. If one period is 30 seconds, then it takes 30 seconds to complete a single revolution.

So, how many revolutions occur in 1 second?  130

That’s your frequency. It should be obvious that this is the inverse of period.

On another note, angular frequency is the angular distance traveled per second, not revolutions. In a circle, each revolution is a full rotation about a circle, which is  2π

 (radians) Hence the angular frequency, given the above period, is the frequency multiplied by  2π

, since one revolution translates to  2π

 units of angular distance.

In summary, if we call  f

 the frequency (revolutions per second),  ω

 the angular frequency (radians per second) and  T

 your period (seconds per revolution), we have the following relations:

T=1f=2πω

ω=2πf=2πT

The spring constant can be determined using the formula for potential energy stored in a spring: PE = 1/2 kx^2, where k is the spring constant and x is the displacement from equilibrium position.

To find the spring constant, we need to rearrange the formula to solve for k: k = 2PE/x^2.

Substituting the given values, we have:

k = 2(3.20 J)/(0.11 m)^2

k = 521.74 N/m

Therefore, the spring constant is 521.74 N/m.

The formula for potential energy stored in a spring is derived from Hooke's law, which states that the force required to compress or stretch a spring is proportional to the displacement from equilibrium position. The constant of proportionality is known as the spring constant.

By knowing the amount of potential energy stored in the spring and the displacement from equilibrium position, we can use the formula to calculate the spring constant.

The formula for potential energy stored in a spring is PE = 1/2 kx^2, where PE is the potential energy stored in the spring, k is the spring constant, and x is the displacement from equilibrium position.

In this problem, we are given that the spring is compressed 11.0 cm from its equilibrium position and stores 3.20 J of potential energy.

We can substitute the given values into the formula and solve for k:

PE = 1/2 kx^2

3.20 J = 1/2 k(0.11 m)^2

k = 2(3.20 J)/(0.11 m)^2

k = 521.74 N/m

Therefore, the spring constant is 521.74 N/m.

The best way to do the experiment on finding the focal length of a concave mirror by obtaining the image of a distant object is to keep both the mirror and the screen in suitable stands with the screen put behind the mirror, hence option D) is correct

The best way to do the experiment on finding the focal length of a concave mirror by obtaining the image of a distant object is to keep both the mirror and the screen in suitable stands with the screen put behind the mirror, which is option (d). This is because a concave mirror forms a real image of a distant object at its focus, and the light rays from the object converge to the focus after reflecting from the mirror. In this case, the distant object should be placed at a distance greater than the focal length of the mirror, and the screen should be placed at the position of the focus of the mirror to obtain a sharp image. By keeping both the mirror and the screen in suitable stands with the screen put behind the mirror, we can ensure that the distance between the mirror and the screen is equal to the focal length of the mirror, which is required to obtain a sharp image of the distant object.

Explanation:

C

Answer:

3a. 240 C

3b. 3666.67 A

Explanation:

3a. Determination of the charge.

Current (I) = 2 A

Time (t) = 120 s

Charge (Q) =?

The charge, current and time are related by the following equation:

Charge (Q) = current (I) × time (t)

Q = It

With the above formula, we can obtain the charge as follow:

Current (I) = 2 A

Time (t) = 120 s

Charge (Q) =?

Q = It

Q = 2 × 120

Q = 240 C

Thus, the charge is 240 C

3b. Determination of the current

We'll begin by converting 220 KC to C. This can be obtained as follow:

1 KC = 1000 C

Therefore,

220 KC = 220 KC × 1000 C / 1 KC

220 KC = 220000 C

Next, we shall express 1 minute in second. This is shown below:

1 min = 60 s

Finally, we shall determine the current. This can be obtained as follow:

Charge (Q) = 220000 C

Time (t) = 60 s

Current (I) =?

Q = It

220000 = I × 60

Divide both side by 60

I = 220000 / 60

I = 3666.67 A

Thus, the current flowing through the bulb is 3666.67 A

Ozone absorbs ultraviolet light best. The correct option is (E).

Ozone is the gas that absorbs ultraviolet (UV) light best among the options listed.

Ozone molecules in the Earth's atmosphere act as a protective layer, absorbing a significant portion of the Sun's harmful UV radiation. This absorption occurs in the stratosphere, particularly within the ozone layer.

The ozone molecule (O3) has a unique structure that allows it to absorb UV light effectively. When high-energy UV radiation interacts with ozone molecules, it causes the bonds to break, resulting in the absorption of the UV energy.

This process converts the UV radiation into heat, reducing the amount of harmful UV light that reaches the Earth's surface.

Carbon dioxide (A), nitrogen (B), oxygen (C), and hydrogen (D) are not as effective in absorbing UV light compared to ozone. While these gases can interact with UV radiation to some extent, their absorption capacities are considerably lower.

It is worth noting that while ozone absorption is essential for protecting life on Earth, human-generated emissions of certain chemicals have contributed to the depletion of the ozone layer, leading to concerns about increased UV radiation reaching the surface and its potential impact on ecosystems and human health.

Stars form from molecular clouds through a process known as stellar formation.

These clouds, characterized by low temperatures and high densities, provide the ideal conditions for atoms to combine and form molecules. With a mass range spanning from a few solar masses to millions of solar masses, molecular clouds serve as the birthplaces of new stars. The Pleiades cluster serves as a notable example of stars that have recently formed within such a stellar nursery.

The formation of stars from molecular clouds involves several key steps. Firstly, gravitational forces acting on regions of higher density within the cloud cause them to collapse under their own gravity. As the cloud collapses, it begins to fragment into smaller, denser clumps called protostellar cores. These cores continue to collapse, and their central regions become increasingly dense and hot. At this stage, they are known as protostars.

Any substance that possesses mass and volume is considered to be matter. In general, atoms and anything composed of them are considered to be "matter."

Energy is the power to effect change or carry out work.

The connection between energy and matter is determined by the speed of light, per the theory of relativity. E = M x C^2, where E is energy, M is mass, and C is the speed of light, describes how matter and energy are related.

Matter and Energy - How are they inter-related?

The variation in a body's mass is inversely proportional to the square of the speed of light and directly correlated with the amount of energy released during the conversion process. An energy conversion process can be carried out by a system using this kind of transformations, in which some of the body's intrinsic energy is converted into thermal energy or radiant light. Also implied by this process is a loss of mass. At the atomic level, the shift of mass is significant because it demonstrates that matter is not an immutable property of the body and that it may, in fact, "disappear," releasing energy to the outside.

The angle of the plate will affect how much sunlight hits the plate. The amount of sunlight that hits a surface depends on the angle of incidence, which is the angle at which the sunlight hits the surface. When the angle of incidence is perpendicular to the surface (i.e., the sun is directly overhead), the maximum amount of sunlight is received by the surface.

However, as the angle of incidence increases, the amount of sunlight that hits the surface decreases because the same amount of sunlight is spread over a larger area. Therefore, if the plate is not angled properly to face the sun, it will receive less sunlight, which will affect its efficiency in converting sunlight into electricity.

The capacitance of the capacitor is approximately 3.976 microfarads (μF) by using the formula - t1/2 = (ln2)(RC)

The given formula, t1/2 = (ln2)(RC), relates the half-life of a capacitor (t1/2) to its resistance (R) and capacitance (C). To find the capacitance, we rearrange the formula as follows: C = t1/2 / (ln2 × R). Plugging in the given values, we have C = 2.30 msec / (ln2 × 32.5 kΩ).

To simplify the calculation, we need to convert the resistance from kilohms to ohms by multiplying it by 1000, resulting in 32.5 × 1000 Ω. By substituting the values into the equation and performing the calculation, we find C = 3.976 μF. Therefore, the capacitance of the capacitor is approximately 3.976 microfarads (μF).
