The emission spectrum for uranium has many more lines than the helium spectrum due to the increased number of energy levels and transitions possible in a neutral uranium atom as compared to a neutral helium atom.

In order to understand why the emission spectrum for uranium has many more lines than the helium spectrum, it's important to understand how emission spectra work. When an atom is excited, for example by heating, electrons in the atom absorb energy and move to higher energy levels or orbitals.

The emission spectrum for helium has only a few lines because it has only two electrons. These electrons occupy only a few energy levels and can only make transitions between these levels, which results in a few emission lines.

However, in the case of uranium, it has 92 electrons which occupy many energy levels. As a result, there are many possible transitions between energy levels, and thus many lines in the emission spectrum. The more electrons an atom has, the more complex its emission spectrum will be.

The pressure inside the Earth increases as depth increases; The temperature drops. Here option B is the correct answer.

As depth increases, the weight of the overlying rock and soil increases, causing an increase in pressure. Additionally, the temperature inside the Earth increases with depth due to the heat generated by the radioactive decay of elements in the Earth's crust.

However, the rate of temperature increase with depth is not as steep as the rate of pressure increase, so the temperature will decrease as the depth increases.

The geothermal gradient is the pace at which Earth's temperature increases with depth. It suggests that the Earth's surface is receiving heat from the planet's heated center. For every kilometer of depth, the temperature rises by around 25°C on average.

The weight of a 10 kg object gravity 9. 8 m/s² is 98 N.

The gravitational force that pulls objects towards the centre of the Earth is known as weight. The subsequent force that a mass is drawn to Earth has something to do with gravity. So unlike gravitational force, which occurs between any two masses, this only occurs between Earth and a mass.

When two objects are in close proximity to one another, their gravitational pull is determined by their respective masses and the inverse square of their respective distances. The forces between larger objects are stronger, and the attraction between smaller objects is weaker as they are further apart. A single weight equation developed by Newton can capture the relationship.

We know that force

F = ma

F = force

m = mass of an object

a = acceleration

Here,

a = g = 9.8 m/s²

m = 10 kg

Then

Force, F = 10 × 9.8

The two cars stick together and move off with a final velocity of 2.5 m/s to the left indicating that there is a loss of kinetic energy, and the collision is inelastic.

In an inelastic collision, two or more objects collide and stick together after the collision, resulting in a loss of kinetic energy. In such collisions, the objects involved deform or undergo some other form of internal interaction that dissipates energy. As a result, the total kinetic energy of the system decreases.

The magnitude of a vector can be described as the length or the size of the vector. It is a scalar quantity and is independent of the direction of the vector.

The direction of a vector can be described as the direction in which the vector is pointing. It is typically represented by a unit vector, which has a magnitude of 1. The direction of a vector can be calculated by normalizing the vector, which involves dividing the vector by its magnitude.

Building involves working with architects to ensure that the design meets all local building codes and regulations. Once approved, the project is ready to begin.

The height of the building can be calculated using the equation:
h = vt + 1/2gt²
where h is height of the building, v is initial velocity, t is time, and g is acceleration due to gravity.
In this case, v = 20 m/s, t = 3.0 s, and g = 9.8 m/s².

Force times distance, or T²L²M, is the dimension of torque. The official SI literature advises that use the unit newton-metre (Nm) and never the joule, despite the fact that these fundamental dimensions are identical to those used for energy or work. The appropriate abbreviation for the newton metre is Nm.

The formula for torque is T = F × r × sinθ. Torque is, in other words, the cross product of the shortest path (the distance between the pivot point and the point at which forces are applied) as well as the force vector, where 'a' is the angle of r and F.

Between the pivot and the location where the force is delivered, measure the distance, r. Calculate the angle between the vector connecting the force's application point and the pivot point and the vector of the applied force. You may calculate the torque by multiplying r by F plus sin.
