How to convert 96 kg to lbs

Answer is C) Core rock samples while radioactive decay and the law of superposition are commonly used methods for this purpose.

Determining the relative age of a rock is the process of placing rocks in a sequential order based on their ages, without assigning numerical ages to them. There are various methods used to determine the relative age of a rock, including radioactive decay and the law of superposition.

Radioactive decay is the process by which unstable isotopes decay and transform into a stable isotope, releasing energy and particles in the process. By measuring the ratio of unstable isotopes to stable isotopes in a rock, scientists can estimate the age of the rock.

The law of superposition is the principle that in a sequence of sedimentary rock layers, the oldest layer is at the bottom, and the youngest layer is at the top. By analyzing the sequence of rock layers, scientists can determine the relative age of a rock.

In contrast, core rock samples are used to extract and study the composition of rocks. Core samples can provide detailed information about the mineralogy, texture, and structure of rocks, but they do not directly provide information about the relative age of a rock. However, core samples can be used in conjunction with other methods, such as radioactive dating, to obtain a more accurate estimate of the age of a rock.

The amount of gravitational force that acts on a space vehicle while in earth orbit is almost zero but not absolute zero.

There is no ground force or opposing natural force to gravity.

Because the earth is not a perfect sphere, the value of "g" is lowest at the equator. At the equator, its radius is at its largest. Thus, the equator is the location where g will be smallest according to the equation

g = GM/R2.

All items in the planet's gravitational field will be lost in space if gravity abruptly vanishes. We would experience levity. Essentially, if gravity is equal to zero, then there will be no acceleration caused by gravity.

The temperature can vary greatly depending on the location. In general, temperatures can range from very hot to very cold. In tropical climates, temperatures can reach up to the mid-30s Celsius (mid-90s Fahrenheit). In colder climates, temperatures can dip down to below -30 Celsius (-22 Fahrenheit). Temperatures can also vary greatly depending on the season. In summer, temperatures can be much higher than in winter. In some areas, temperatures can also vary depending on altitude, with higher altitudes having cooler temperatures.

B. The value of the rate constant at 16∘C can be estimated using the Arrhenius equation, which is k = A e^(-Ea/RT), where A is the pre-exponential factor, Ea is the activation energy, R is the universal gas constant, and T is the temperature in Kelvin. Plugging in the values for the two known temperatures, we get A = 1.25×10−4 s−1 and Ea/R = (0.230-1.25×10−4)/(8.314*(78+273)) = 6806.4 K.

The required age of the rock when half-life of a radioactive isotope is given is calculated to be 16252.3 years.  

First order kinetics' equation for calculating rate constant from provided half-life

t1/2 = 0.693/k

t1/2 = 7000 years

Making k as subject,

k = 0.693/7000 = 0.000099 = 9.9 × 10⁻⁵ yr⁻¹

Ratio of parent isotope : daughter isotope = 1 : 4

Let's suppose that the parent isotope weighs 100 g.

The amount of daughter isotope calculated to be 80 g.

So, the amount of parent isotope left is 100 - 80 = 20 g.

The formula used to determine time interval is as follows:

N = N₀ e⁻kt

where,

N₀ is the initial mass of the isotope 100g

N is the mass of the parent isotope left is 20g.

Time t in years is to be found out.

k = rate constant = 9.9 × 10⁻⁵ yr⁻¹

Putting values in above equation, we get,

20 = 100 e^(-9.9 × 10⁻⁵)t

1/5 = e^(-9.9 × 10⁻⁵)t

log(0.2) = -9.9 × 10⁻⁵ t

t = - log(0.2)/9.9 × 10⁻⁵ = -(-1.609)/9.9 × 10⁻⁵ = 1.609/9.9 × 10⁻⁵ = 10⁵ × 1.16 = 16252.3 years

The axis of the Earth is tilted because of the way it was formed and the forces acting upon it.

The most widely accepted theory is that the Earth was formed about 4.5 billion years ago from the solar nebula, a rotating disk of gas and dust that surrounded the young Sun. As the disk began to cool and contract, it flattened into a disk, and the Earth formed within it. The gravitational forces of the Sun and Moon acting on the Earth caused it to become slightly flattened at the poles and bulging at the equator, and this resulted in a tilting of the Earth's axis. The tilt of the Earth's axis has remained relatively constant over time, leading to the seasons we experience as the Earth orbits the Sun.

Using the solar constant,  the rate at which the whole earth receives energy from the sun is 1.475×10²⁴ W.

The solar constant (GSC) is a measure of the flux density of the sun's electromagnetic radiation (gross solar radiation) averaged per unit area. It is measured on the surface perpendicular to the light rays, one astronomical unit (au) from the sun (approximately the distance from the sun to the earth).

The solar constant includes radiation across the electromagnetic spectrum. The satellite measured a solar minimum (the period of the 11-year solar cycle when the number of sunspots is lowest) at 1,361 kilowatts per square meter (kW/m2), or about 0. Add 1% (about 1362 kW/m2) to the solar maximum.

According to the Question:

I = Solar constant of the sun = 1362 W/m²

(Using satellite measurements, the value is 1.3608 ± 0.0005 kW/m², the error is due to the solar production not always being constant)

r = Radius of earth = 6371 km = 6371000 m (mean radius)

A = Area of earth = (4/3)×π×r³

  = (4/3)× π ×6371000³

a. ungrounded

b. grounded (neutral)

c. both a and b

d. none of the above

The correct answer to part A is: "The magnitude of the normal force is equal to the magnitude of the weight of the suitcase." So, the correct option is B. This is because the normal force is the force exerted by the floor on the suitcase perpendicular to the surface of contact.

According to Newton's third law, for every action, there is an equal and opposite reaction. When the man pulls upward on the suitcase, the suitcase exerts an equal and opposite force downward on the man. This force is the weight of the suitcase, which is the force exerted on the suitcase by the Earth due to gravity. The normal force is the force exerted by the floor on the suitcase perpendicular to the surface of contact.

Since the suitcase is not lifted from the floor, it means that the forces are in equilibrium, and the net force on the suitcase is zero. Therefore, the magnitude of the normal force must be equal to the magnitude of the weight of the suitcase to balance the force of the pull. So option B is the correct answer. Options C, D, and E are incorrect because they do not take into account the fact that the forces must be in equilibrium.
