The distance traveled between seconds 3 and 4 is greater than the distance traveled between seconds 1 and 2 because: an object falling due to gravity moves faster every second. Hence, option (C) is correct.

Any motion of a body in which gravity is the only force acting on it is referred to as free fall in Newtonian physics.

An object may not necessarily be falling down in the traditional sense of the word while it is in a "free fall" in a technical sense. Even if an object going upwards isn't typically thought of as falling, it is said to be in free fall if it is just being affected by gravity.

As during feel force gravitational force works on the object continuously, the velocity of the object increases continuously. Hence, the distance traveled between seconds 3 and 4 is greater than the distance traveled between seconds 1 and 2 .

The stretch in a spring can be calculated using the formula:

where delta_x is the stretch, F_spring is the force applied on the spring and k is the spring constant.

The force applied on the spring is equal to the weight of the mass, which is 7.3 kg, multiplied by the acceleration due to gravity (9.8 m/s^2):

So the stretch in the spring can be calculated as follows:

The Stretch of a spring is analogous to the vibration of a pendulum. This is because there is an alternating movement of the spring past the balance point. Stretch on the spring also has a tension restoring force according to Hooke's law: Fs = -K.X Where K is the spring constant, and X is the stretch length.

Water turns from a liquid to a solid/liquid/gas when it evaporates. Ice can also evaporate. Sublimation is the transformation of solid ice into a gas (water vapour).

The right response is sublimation. Without passing through a liquid phase, sublimation is the transformation of a solid into a gaseous phase of matter. Deposition, which occurs when water vapour transforms straight into ice, such as in snowflakes and frost, is the reverse of sublimation.

A specific amount of solid ice will have a smaller volume when it transforms into liquid water because melting ice produces denser water.

The temperature in Kelvin (K) is equal to the temperature in Celsius (°C) plus 273.15.

The Celsius and Kelvin temperature scales are two common temperature scales used in science. The relationship between these two scales can be described by a simple equation.

To convert a temperature from Celsius to Kelvin, you add 273.15 to the Celsius temperature. This equation is derived from the fact that the Kelvin scale starts at absolute zero, which is -273.15°C. Therefore, to account for the offset between the two scales, 273.15 is added to the Celsius temperature to obtain the equivalent temperature in Kelvin.

For example, if you have a temperature of 25°C, you can convert it to Kelvin by adding 273.15:

25°C + 273.15 = 298.15 K

So, 25°C is equivalent to 298.15 K.

This equation holds true for any temperature value in Celsius. By adding 273.15 to a Celsius temperature, you obtain the corresponding temperature in Kelvin.

In summary, the equation K = °C + 273.15 represents the conversion between Celsius and Kelvin temperatures, where K represents the temperature in Kelvin and °C represents the temperature in Celsius. Adding 273.15 to a Celsius temperature gives the equivalent temperature in Kelvin.

Answer: Different types of fuels have varying compositions and release different amounts of pollutants when burned. Here are some common types of fuels and the pollutants associated with them:

Fossil Fuels:

a. Coal: When burned, coal releases pollutants such as carbon dioxide (CO2), sulfur dioxide (SO2), nitrogen oxides (NOx), and particulate matter (PM).

b. Petroleum (Oil): Burning petroleum-based fuels like gasoline and diesel produces CO2, SO2, NOx, volatile organic compounds (VOCs), and PM.

Natural Gas:

Natural gas, which primarily consists of methane (CH4), is considered a cleaner-burning fuel compared to coal and oil. It releases lower amounts of CO2, SO2, NOx, VOCs, and PM.

Biofuels:

Biofuels are derived from renewable sources such as plants and agricultural waste. Their environmental impact depends on the specific type of biofuel. For example:

a. Ethanol: Produced from crops like corn or sugarcane, burning ethanol emits CO2 but generally releases fewer pollutants than fossil fuels.

b. Biodiesel: Made from vegetable oils or animal fats, biodiesel produces lower levels of CO2, SO2, and PM compared to petroleum-based diesel.

Renewable Energy Sources:

Renewable energy sources like solar, wind, and hydropower do not produce pollutants during electricity generation. However, the manufacturing, installation, and maintenance of renewable energy infrastructure can have environmental impacts.

It's important to note that the environmental impact of a fuel also depends on factors such as combustion technology, fuel efficiency, and emission control measures. Additionally, advancements in clean technologies and the use of emission controls can help mitigate the environmental impact of burning fuels.

When air rises in a low-pressure system, it can lead to the formation of clouds and precipitation, such as rain or snow. The rising air also cools and condenses, releasing latent heat, which can further contribute to the development of the storm.

A low-pressure system is a weather pattern characterized by a region of lower atmospheric pressure compared to the surrounding areas. It is often associated with unsettled and stormy weather.

Clouds are formed when moist air rises and cools, causing water vapour to condense into tiny water droplets or ice crystals. This process occurs when the temperature of the air decreases, either because it is rising, or because it is mixing with cooler air.

Answer:

The carbon atom has greater kinetic energy than a hydrogen atom.

Hope this helps! :)

Carbon atom has the greater kinetic energy.

Kinetic energy is defined as the energy attained by a body by virtue of its motion.

Here,

The speed of the hydrogen atom and carbon atom are the same.

Kinetic energy of hydrogen atom, KEн = 1/2 m(н) v(н)²

Kinetic energy of carbon atom, KEс = 1/2 m(с) v(с)²

where m and v are mass and speed respectively.

Taking the ratio,

KEн/KEс = m(н)/m(с)

KEн/KEс = 2/12

KEн/KEс = 1/6

KEс = 6KEн

Therefore the kinetic energy of carbon atom is 6 times the kinetic energy of hydrogen atom.

Hence,

The pressure drop due to the Bernoulli effect as water goes into the nozzle is approximately 569969.28 N/m^2 or 569969.28 Pa.

To find the pressure drop (ΔP) due to the Bernoulli effect as water goes into the nozzle,

We need to calculate the velocities (v1 and v2) and substitute them into the pressure drop formula.

Given:

Diameter of the fire hose (D1) = 8.9 cm = 0.089 m

Diameter of the nozzle (D2) = 3.5 cm = 0.035 m

Flow rate (Q) = 35 L/s = 0.035 m^3/s

Density of water (ρ) = 1000 kg/m^3

Calculating the cross-sectional areas:

A1 = (π/4) * D1^2

A2 = (π/4) * D2^2

Calculating the velocities:

v1 = Q / A1

v2 = Q / A2

Substituting the values into the equations:

A1 = (π/4) * (0.089 m)^2 ≈ 0.00622 m^2

A2 = (π/4) * (0.035 m)^2 ≈ 0.000962 m^2

v1 = 0.035 m^3/s / 0.00622 m^2 ≈ 5.632 m/s

v2 = 0.035 m^3/s / 0.000962 m^2 ≈ 36.35 m/s

Using the pressure drop formula:

ΔP = (1/2) * ρ * (v2^2 - v1^2)

ΔP = (1/2) * 1000 kg/m^3 * ((36.35 m/s)^2 - (5.632 m/s)^2)

ΔP ≈ 569969.28 N/m^2 ≈ 569969.28 Pa

Therefore, the pressure drop due to the Bernoulli effect as water goes into the nozzle is approximately 569969.28 N/m^2 or 569969.28 Pa.

n2 is final amount and n1 is beginning and t is either time elapsed as in the first formula or the actual half life that is t1/2

Explanation:

The half life of the sample will be "4 days".

According to the question,

Let,

→  \(\frac{N}{N_o} = (\frac{1}{2} )^n\)

By substituting the values, we get

→  \(\frac{2}{128} = (\frac{1}{2} )^n\)

→    \(\frac{1}{64} = (\frac{1}{2} )^n\)

→ \((\frac{1}{2} )^6= (\frac{1}{2} )^n\)

→     \(n=6\)

So,

It takes 6 half life just to reduce from 128 mg - 2mg which is also "24 days".

→ \(6 \ half \ life = 24 \ days\)

Hence,
