Gravitational force depends on mass and gravity.

Gravity has a force called gravitational force which is the force that pulls an object toward the earth. example, A leaf or fruit falls from a tree to the ground, river water flows down a river, or a ball is thrown up and lifted up and returned to the ground, to name a few examples of motion due to gravity. It is the force that exists between all objects in the universe. Two non-zero mass objects or particles are attracted to each other by gravity.

The ECG (electrocardiogram) records electrical activity within the heart, while the pulse wave records the physical pressure of the heart’s contractions.

The timing of the QRS complex in the ECG and the maximum height of the pulse do not coincide because the electrical impulse from the heart arrives at the body's surface before the physical pressure of the heart's contraction is felt.

The electrical impulse reaches the surface of the body faster than the physical pressure, causing a discrepancy between the two signals. In addition, the electrical impulse is usually larger than the physical pressure, which results in the QRS complex in the ECG having a higher peak than the pulse wave.

Newton's 3rd law states that for every action there will always be an equal and opposite reaction. 2 examples of newton's 3rd law are a) launching of a rocket, b) firing a bullet from the gun.

Newton's 3rd law states that for every action there will always be an equal reaction in the opposite direction. When a rocket is launched from the earth, it applies a force on the ground that generate the enough reaction force that causes the rocket to generate orbital velocity.

On the other hand, when a bullet is fired from a gun it applies a force on the gun, which generate a recoil velocity in the gun. The gun also applies equal reaction to the bullet. As the bullet mass is very less as compared to the gun, so the velocity generated in the bullet will be much higher than the recoil velocity.

The SI unit of momentum is kilogram meters per second (kg*m/s).

This unit of measurement is used to express the momentum of an object in the International System of Units (SI). The kilogram is the base unit of mass in the SI and the meter per second (m/s) is the base unit of velocity in the SI. When we multiply the two, we get the unit of momentum. It is a vector quantity having both magnitude and direction. Momentum is an important concept in physics and it is used to describe the motion of objects, from subatomic particles to galaxies. The principle of conservation of momentum is widely used in physics, particularly in fields such as mechanics, thermodynamics, and quantum mechanics.

Momentum is a measure of an object's motion. Momentum is the product of an object's mass and velocity, and is represented by the symbol "p." In physics, momentum is considered to be a vector quantity, meaning it has both magnitude and direction.

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.

Explanation:

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

= 98 N

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

The gravitational field strength of the Earth is 9.8 N/kg. Accordingly, an item will experience 9.8 N of force for every kg of mass. The weight of an object is smaller where the gravitational field is weaker.

The Moon, for instance, has a gravitational field that is 1.6 N/kg strong. This indicates that an object will encounter 1.6 N of force for every kg of mass. An astronaut will therefore be lighter on the Moon than they are on Earth.

One of the most significant forces in the universe is gravity. Weight is the force that an object with mass experiences when it is in a gravitational field.

Gravitational weight is not usually immediately apparent. The International Space Station astronauts look to be weightless. They still have weight, though, because they are still in orbit around the Earth and are subject to its gravitational field. Because they and the space station are always descending toward Earth, they appear to be weightless.

According to the problem the building is approximately 59 meters tall.

Building is the process of constructing a structure from individual components. It involves the planning, design, and construction of a structure with the use of materials such as wood, metal, concrete, and other materials. 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.

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 magnitude of a vector is a scalar value and is independent of the direction of the vector. The direction of a vector is typically represented by a unit vector, which has a magnitude of 1.

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 magnitude can be calculated using the formula: |a| = √(a.x² + a.y² + a.z²) where a.x, a.y, and a.z are the x, y, and z components 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.
