What is the standard unit to measure force?

Time period and frequency of its oscillation are 3 sec and 0.33 hertz.

Explanation:

A pendulum is used to describe the too and flow motion of it which is caused due to gravity. A bob consisting of less mass suspended from upper surface by pivot and it is the one which swings due to gravity.

Given:

A simple pendulum makes 12 oscillations in 4 seconds.

time period=?

frequency=?

As pendulum makes 12 oscillations in 4 seconds.

The time taken by pendulum for making one oscillation is 12/4 sec = 3 sec.

Time period = 3 sec.

Frequency of the pendulum's oscillations is found by the formula

Frequency = 1/T = 1/3 = 0.33 Hz

∴Time period and frequency of its oscillation are 3 sec and 0.33 hertz.

Frequency and Period of the pendulum's oscillations is 3 and 0.33 Hz.

Given that;

Number of oscillates = 12 times

Total time taken = 4 sec

Find:

Frequency of oscillations

Period of oscillations

Computation:

Period of the oscillations = 12 / 4

Answer: Neither Event 1 nor Event 2

Explanation:

Let's begin by explaining when a total solar eclipse occurs:

A total solar eclipse occurs when "the Moon hides the Sun" (as seen from Earth).  

So, in order to make this situation posible, the Sun, Moon, and Earth must be aligned in the plane of the ecliptic; and Moon must be in the New Moon phase.  When this happens, the Moon completely covers the solar disk.

Hence, according to his explanation, Neither Event 1 nor Event 2 describe a Total Solar Eclipse, since Event 1 is not related to a solar eclipse and Event 2 describes an annular solar eclipse on Earth.

Explanation:

Final answer:

The potential energy an object has due to its position is called gravitational potential energy. It is related to an object's height relative to a gravitational source, typically Earth, and increases with elevation. Another form, elastic potential energy, is stored in stretched or compressed objects.

Explanation:

The potential energy an object has due to its position is called gravitational potential energy. This type of energy is a function of an object's position relative to a source of gravitational force, usually Earth for problems encountered in middle and high school physics. Gravitational potential energy increases as the height of an object increases relative to a reference point, commonly ground level. For example, a book placed on a higher shelf has more gravitational potential energy compared to when it is on a lower shelf because it has the potential to do more work if it falls.

Another form of potential energy relevant in physics is elastic potential energy, which is stored in objects like springs and rubber bands when they are stretched or compressed. This energy is a function of the displacement and the stiffness of the object, as described by Hooke's Law.

Answer:

The force responsible for circular motion is acting toward the middle of the loop.

Explanation:

When a roller coaster goes in an upside-down loop, the force responsible for circular motion is acting toward the middle of the loop. The correct option is A.

When a roller coaster rides through an upside-down loop, the force that causes circular motion acts towards the centre of the loop.

This force is known as the centripetal force, and it operates perpendicular to the roller coaster's velocity at each point of the loop.

To keep the roller coaster travelling in a curved course and from flying off the track, centripetal force is required.

The centripetal force pushes the roller coaster inward as it enters the loop, providing the necessary acceleration to maintain its round track.

This force keeps the roller coaster safely on the track and gives passengers the exhilarating sensation of being inverted.

Thus, the correct option is A.

Conduction can occur in all states of matter, including solid, liquid, gas, and plasma. This process involves the transfer of heat through stationary matter by direct physical contact, a result of the thermal motion of atoms and molecules.

Conduction, which in the context of physics refers to heat transfer through stationary matter by physical contact, can occur in all three common states of matter - solids, liquids, and gases. This transfer is due to the thermal motion of atoms and molecules at any temperature above absolute zero. For instance, heat is transferred between an electric burner of a stove and the bottom of a pan by conduction. This is because the energetic motion of particles in one area spreads to other regions, and even to adjacent objects in close contact.

In the solid state, conduction is quite efficient because the particles are closely packed and can readily transfer energy to their neighbors. In liquids and gases, the particles are more spread out, but conduction still occurs, albeit at a slower pace. A fourth state of matter, plasma, also exists and conductive heat transfer occurs within this state because it contains appreciable numbers of electrically-charged particles.

Answer:

B, Energy that is expended to push on an object.

Explanation:

Work is the usage of energy to make an object go a certain distance.

Answer:

given.. mass of copper 2kg

from the concept

heat lost from an object=heat gained by the other object

Heat=McΔT

Mč x Cč x ΔTč = Mw x Cw x ΔTw

2kg x 385J/kg°C x (100°c - {F}) = 5kg x 4200J/kg°C x ({f} - 20°C)

77000 - 770F = 21000F - 420,000

21770F =497000

....divide both sides....

F=22.83°C

therefore the final temperature of the water was 22.83°C

Explanation:

Newton's Law of Gravitation states that:

[tex]F_G = \frac{-Gm_1m_2}{r^2}[/tex]

If the masses of each object is small, then [tex]m_1*m_2[/tex] would be very small, making the gravitational force between the two objects hard to detect - as it itself would be very small.

Answer&Explanation:

According to the Newton gravitational law is directly proportional to the Product between masses and inversely proportional to the square of the distance..

Hence from the law and corresponding question the correct answer is D:if the mass of each object is very small

Thus it would make it undetectable

Answer:

Explanation:

Oxygen has an atomic number of 8,

Then, it has eight electrons revolving round its nucleus.

And since it a neutral atoms.

Number of neutron ≈ number of electron

Number of proton = Number of electron.

Then, the number of proton is 8

So, we can find it mass number of molecular weight

Molecular weight = number of proton + number of neutron

Molecular weight = 8 + 8

Molecular weight = 16g/mol

So, the correct answer is D

An atom of oxygen has 8 protons.

Answer C is INCORRECT. The correct answer is "Rotation of liquid iron in the outer core." For example the text from my course states that "As Earth spins on its axis, rotation of the liquid outer core generates Earth's magnetic field."

The statement best explains how Earth's magnetic field is generated by the Rotation of liquid iron in the outer core

Earth's magnetic field, also known as the geomagnetic field, is the magnetic field that extends from Earth's interior out into space, where it interacts with the solar wind, a stream of charged particles emanating from the Sun.

The magnetic field is generated by electric currents due to the motion of convection currents of a mixture of molten iron and nickel in Earth's outer core

The inner core (which is solid) is the hottest layer of the earth. It, therefore, contributes to heating up the outer core. The outer core is liquid and rotation of the earth (Coriolis effect) causes the molten rocks to swirl like a tornado.

Because the outer core is mostly made of metals, that have lost electrons and hence charged (due to the enormous heat), the swilring effect causing an electric effect.

This consequently causes the dynamo effect that creates a magnetic field. This magnetic field covers the earth and protects it from harmful radiation from the solar storms.

Answer: Some household items that contain acids include: yogurt, vinegar,lemon juice, citric acid, apples, jelly, pineapples, cranberry sauce, milk, and batteries and In chemistry, pH is a scale used to specify how acidic or basic a water-based solution is. Acidic solutions have a lower pH, while basic solutions have a higher pH. At room temperature, pure water is neither acidic nor basic and has a pH of 7.

Solubility is the capacity of a solute to dissolve in a solvent. Warm temperatures often increase the solubility of solids and liquids, but reduce the solubility of gases like oxygen. This is why warmer ocean waters and artificially warmed waters can contain less oxygen, potentially leading to negative effects on aquatic life.

In the video, Mr. Anderson defines solubility as the maximum amount of solute that can be dissolved in a specific amount of solvent at a given temperature. For instance, the solubility of talc in water at 25 °C is fundamentally none because talc is a mineral compound that does not interact with water molecules to any significant extent. Talc particles will simply settle to the bottom rather than dissolve.

The solubility of both solid and liquid solutes usually increases with temperature, although there are exceptions. The increase in kinetic energy that comes with higher temperatures allows solute particles to break apart more easily and become dispersed throughout the solvent.

Ocean water near the equator contains less dissolved oxygen than water at higher latitudes due to the effect of temperature on gas solubility. The higher temperatures near the equator decrease the solubility of oxygen, leading to lower concentrations. In the scenario of fish dying in the part of a stream into which a factory discharges clean, warm water, the likely cause is a decrease in the solubility of oxygen due to the temperature rise, leading to insufficient oxygen for the fish to survive.
