Answer:

\(\boxed {\boxed {\sf E_K= \ 5,040 \ J}}\)

Explanation:

Kinetic energy is the energy an object possesses due to motion. It is calculated using the following formula:

\(E_K= \frac{1}{2} mv^2\)

The mass of the athlete is 70.0 kilograms. The velocity is 12 meters per second.

Substitute the values into the formula.

\(E_K= \frac{1}{2} (70.0 \ kg)(12 \ m/s)^2\)

Solve the exponent.

\(E_K= \frac{1}{2} (70.0 \ kg)(144 \ m^2/s^2)\)

Multiply the numbers together.

\(E_K= \frac{1}{2} (10, 080 \ kg*m^2/s^2)\)

\(E_K= 5,040 \ kg*m^2/s^2\)

Convert the units. 1 kilogram meter squared per second squared is equal to 1 Joule, so our answer is equal to 5,040 Joules.

\(E_K= 5.040 \ J\)

The athlete has 5,040 Joules of kinetic energy.

\(\\ \sf\longmapsto s=ut+\dfrac{1}{2}at^2\)

\(\\ \sf\longmapsto 163=0(6.92)+\dfrac{1}{2}a(6.92)\)

\(\\ \sf\longmapsto 163=3.46a\)

\(\\ \sf\longmapsto a=\dfrac{163}{3.46}\)

\(\\ \sf\longmapsto a=47.1m/s^2\)

Pressure (P) = F/A

diameter = d = 1.80 cm = 0.018 m

F = force = 16.5 N

Volume pump = 5 L = 5000 cm^3 = 0.005 m^3

Area = pi* r^2 = pi* (0.018/2)^2 = 2.54 x10^-4 m^2

P = 16.5 / 2.54 x10^-4 = 64,840.9 N/m^2

The Redfield ratio is the ratio of various chemical elements present in the average phytoplankton biomass. This defines the stoichiometry of photosynthesis and remineralization reactions.

The Redfield ratio is 106:16:1 across the ocean. Many models predict that a warmer ocean will hold less carbon because phytoplankton will become smaller as the ocean warms and bring less carbon to the seafloor as they die. Carbon nitrogen and phosphorus are the most important of these nutrients and CNP.

A ratio between 100:5:1 and 100:10:1 should be maintained to ensure maximum microbial activity in aerobic wastewater treatment. Many trace elements or micronutrients are also required. This is because a specific form of nitrogen found in the air nitrogen gas cannot be assimilated by most living organisms or require nitrogen in solid form.

The best combination of climatic conditions to maximize net primary productivity is warm temperatures, moderate precipitation, and ample sunlight.

Net primary productivity (NPP) refers to the rate at which plants and other autotrophs convert sunlight into biomass through photosynthesis, minus the amount of energy used in respiration. The climatic conditions that promote NPP are warm temperatures that allow for efficient photosynthesis, moderate precipitation to supply water and nutrients to plants, and ample sunlight for photosynthesis.

These conditions are typically found in regions with a temperate or tropical climate. However, excessive rainfall or drought can limit NPP, as can extreme temperatures or insufficient sunlight. Human activities, such as deforestation and land use change, can also reduce NPP by decreasing the amount of plant biomass available for photosynthesis. Overall, a balance of climatic conditions is essential for maximizing NPP and maintaining healthy ecosystems.

Since the particle moves with constant velocity, its direction of motion is the same as the direction of the displacement vector between its two position vectors.

To determine the direction of the particle's velocity, you need to subtract the initial position vector from the final position vector (assuming the final position occurs later than the initial position). Then, divide the resulting vector by the time interval between the two positions. The resulting velocity vector will give you the direction of the particle's velocity. From the picture provided, we can see that the displacement vector points from the earlier position towards the later position. Therefore, the direction of the velocity of the particle is also in the same direction as the displacement vector, which is from the earlier position towards the later position.

Answer:

Selenium dichloride

Explanation:

Selenium (Se) and Chlorine (Cl) are both elements capable of combining together to form a compound with the chemical formula; SeCl2. Since the chlorine atom is more electronegative than selenium atom, the chlorine pulls more electrons towards itself to form an IONIC bond.

The SeCl2 compound formed is called Selenium dichloride as two atoms of Chlorine are needed to combine with one atom of Selenium to form the compound.

The name of the molecular compound is selenium dichloride (SeCl2).  

• Due to sharing of electrons between selenium and chlorine, Selenium dichloride is considered as covalent compound.  

• Both the elements are non-metals, and thus, would give rise to covalent bond.  

• Selenium is the least electronegative element of the two, so it is written first.  

• After that the more electronegative element is written, and then addition of suffix is done, that is, -ide.  

• If atoms of an element is more than one, then prefixes are supplemented that is mono for 1 atom, di for two atoms, and tri for three atoms.  

Thus, the name of the molecular compound is selenium dichloride.

The tension in the lower segment of the belt is 219 N. To find the tension in the lower segment of the belt, we can start by analyzing the forces acting on the flywheel.

The net torque acting on the flywheel can be expressed as the product of its moment of inertia and angular acceleration, given by the equation:

\(\[ \tau = I \alpha \]\)

Since the axle is frictionless, the only torque acting on the flywheel is due to the tension in the lower segment of the belt. The moment of inertia of a solid disk can be calculated using the equation:

\(\[ I = \frac{1}{2} m r^2 \]\)

where m is the mass of the flywheel and r is its radius. Substituting this into the torque equation, we have:

\(\[ T_{\text{u}} \cdot r_{\text{pulley}} = \frac{1}{2} m r^2 \cdot \alpha \]\)

Rearranging the equation, we can solve for the tension in the lower segment of the belt:

\(\[ T_{\text{u}} = \frac{1}{2} \frac{m r^2 \alpha}{r_{\text{pulley}}} \]\)

Plugging in the given values, with the mass of the flywheel (m = 66.5 kg), radius of the flywheel (r = 0.625 m), radius of the pulley \((r_{\text{pulley}} = 0.230 m)\), and the angular acceleration \((\alpha = 1.67 rad/s^2)\), we can calculate the tension in the lower segment of the belt:

\(\[ T_{\text{u}} = \frac{1}{2} \frac{66.5 \cdot 0.625^2 \cdot 1.67}{0.230} = 219 \, \text{N} \]\)

Therefore, the tension in the lower segment of the belt is 219 N.

The color of visible light that would have the least energy is red. On the other hand, the color of visible light that would have the most energy is violet.

This is because red light has the longest wavelength and the lowest frequency out of all the colors in the visible spectrum. Violet light has the shortest wavelength and the highest frequency out of all the colors in the visible spectrum.

This relationship between wavelength, frequency, and energy can be explained by the relationship between electromagnetic waves and energy. All electromagnetic waves, including visible light, have a certain amount of energy that is proportional to their frequency. The higher the frequency, the more energy the wave has.

This relationship can also be seen in the electromagnetic spectrum, where higher energy waves (such as X-rays and gamma rays) have shorter wavelengths and higher frequencies, while lower energy waves (such as radio waves) have longer wavelengths and lower frequencies.

The thermal efficiency of this engine is calculated by taking the net power output of 50 kW and dividing it by the amount of heat input of 200 kW. Thus, the thermal efficiency of this engine is 25%.

The thermal efficiency of a heat engine is defined as the ratio of the net power output of the engine to the heat input. In this case, the heat engine is accepting heat at a rate of 200 kW and producing a net power output of 50 kW.

To calculate the thermal efficiency, we use the following equation: Thermal Efficiency = Net Power Output/Heat Input In this case, the net power output is 50 kW and the heat input is 200 kW. Therefore, the thermal efficiency of this engine is equal to 0.25 or 25%. It is important to note that the thermal efficiency of a heat engine is affected by several factors, such as the efficiency of the engine itself, the temperature of the heat source, the temperature of the heat sink, and the type of energy conversion being performed. Therefore, the thermal efficiency of any engine may vary from one situation to another.

Answer:

This is because we have a greater likelihood of obtaining a valid estimate. When we use extrapolation, we are making the assumption that our observed trend continues for values of x outside the range we used to form our model.

Thermal energy is transferred between objects only when they have different temperatures.

The movement of atoms and molecules within a substance is a form of energy known as thermal energy.

When two objects are in contact, or even in proximity, the atoms and molecules in the hotter object collide with those in the colder object.

Because of these effects, a portion of the kinetic energy from the more sizzling object is moved to the colder object, raising the temperature of the previous and bringing down the temperature of the last option.

A material's thermal conductivity — an estimation of how well it moves heat — decides how rapidly heat is moved between various sorts of materials.
