Specific heat of iron = 0.4498

Answer:

58.8 N

Explanation:

Since the ball is hanging at rest, the net force on the ball must be zero.

There are only two forces acting on the rope:

- Its weight, downward, given by W = mg, where m = 6 kg is the mass of the ball and g=9.8 m/s^2 is the acceleration due to gravity

- the tension in the rope, T, upward

Therefore, the equation for the forces is:

[tex]T-W=0[/tex]

And solving for T, we find:

[tex]T=W=mg=(6 kg)(9.8 m/s^2)=58.8 N[/tex]

Because like poles repel and unlike poles attract. This is a property of every magnet.

Final answer:

Magnets have both north and south poles, which cannot be separated; like poles repel each other, preventing north poles or south poles from meeting. Cutting a magnet results in new pairs of poles, as they always occur in pairs.

Explanation:

Every magnet has two types of poles, a north pole and a south pole. These poles always come in pairs and cannot be separated; they exhibit a fundamental property of magnets. The reason a north pole does not meet another north pole, or a south pole another south pole, is due to the magnetic fields that they generate. Like poles will always repel each other, which means the north pole of one magnet will repel the north pole of another magnet, and the same goes for two south poles.

When a magnet is cut, even into very small fragments, each piece will retain a north and a south pole. It is impossible to isolate a north pole or a south pole on its own, which is a basic principle of magnetism. Therefore, regardless of how much you divide a magnet, you will never end up with a single pole; new pairs of poles will emerge in each fragment. This inherent characteristic is verified by experiments and is even observable on the atomic level with elements that exhibit magnetic properties, such as iron.

Final answer:

Climate change is primarily driven by the emission of greenhouse gases like carbon dioxide and methane, mainly from the burning of fossil fuels, deforestation, agriculture, and manufacturing. Human-caused factors are the most significant contributors to the current rates of global warming, surpassing natural influences on the climate.

Explanation:

One significant factor contributing to climate change is the emission of greenhouse gases such as carbon dioxide (CO2) and methane. The largest driver of warming comes from burning fossil fuels like coal, oil, and natural gas, which is the main source of CO2 emissions. This is further compounded by deforestation, agriculture, and manufacturing. Other manmade causes include increases in near-surface ozone from internal combustion engines, and aerosols such as carbon black and dust, which impact the Earth's albedo and its ability to reflect solar radiation.

It is essential to distinguish between natural factors that have historically influenced climate, such as changes in Earth's orbital patterns, plate tectonics, solar output, and volcanic activity, versus the anthropogenic (human-caused) factors driving the current unprecedented rates of climate change. Human-related factors far outweigh natural influences, which cannot fully explain the rapid increase in global temperatures observed today. The use of fossil fuels for energy and transportation is identified as the critical factor in fueling the current trend of climate change, contributing directly to the greenhouse effect.

Efforts to reduce emissions, transition to renewable energy sources, and implement more sustainable practices are vital steps in addressing the ongoing climate crisis. This reflects a dire need for coordinated global action to mitigate the impacts on food supply, water resources, ecosystems, and human health.

the answer is 46 because the year is 2047 and you was eighteen in 2019 so you was born in 2001

To calculate the age after 28 years from getting married at age 18 in 2019, you add 28 to 18, resulting in an age of 46 years.

If someone gets married at the age of 18 in the year 2019, to calculate their age after 28 years have passed, you simply add 28 to their age at marriage. Here's the step-by-step calculation:

Therefore, after 28 years have passed since getting married in 2019, the person would be 46 years old.

Spectrometer is the tool used by scientists to determine the composition of objects. So, option B is correct.

Spectroscopy is defined as the technique of studying the structure and properties of matter by using radiations.

Here,

The method of spectroscopy is that it analyses matter by using radiations. In this process, the radiations emitted and absorbed by the particles are analyzed. The instrument used is called spectrometer. Thus the absorption spectra and emission spectra of the particle are obtained. From this, the interaction of the particle with the materials in form of energy can be studied. Spectroscopy can be called as the measurement of the matter-energy interactions by means of radiation and their wavelengths as the function of energy. Spectroscopy and its applications have been widely used in many of the theories in physics. Quantum mechanics and relativity theories and many others has been developing their theories by the major applications of spectroscopy. Study of material particles are widely done by spectroscopy

Hence,

The temperature of the gas will be cold, because the atoms move very slow,

Answer:

cold

Explanation:

According to kinetic theory of gases, gases at same temperature have same kinetic energy. The speed (v) of the particles of the gas is directly proportional to the temperature (T) of the gas.

K.E. ∝ T

v ∝ T

In the given situation, the atoms of gas are moving very slowly. This means that the temperature of the gas must be very low. The temperature of the gas would be cold.

Answer:

B) the law of reflection

Explanation:

When a light ray reflects off a surface, it obeys the law of reflection.

A few definitions before giving the law of reflection:

- The angle of incidence is defined as the angle between the incident ray and the normal to the surface

- The angle of reflection is defined as the angle between the reflected ray and the normal to the surface

The law of reflection states that:

- The angle of incidence is equal to the angle of reflection

- The incident ray and the reflected ray lie both on the same plane.

Answer:

Larger than the object

Explanation:

The magnification of a lens/mirror is given by the equation:

[tex]M=-\frac{h_i}{h_o}[/tex]

where

[tex]h_i[/tex] is the size of the image

[tex]h_o[/tex] is the size of the object

from the formula, we see that if M is greater than 1, it means that [tex]|h_i|>|h_o|[/tex]

and so, it means that the image is larger than the object.

The negative sign simply tells if the image is upright or inverted: when M is positive, the image is upright, when M is negative, the image is inverted.

Answer:

Larger than the object

Explanation:

If there is really no friction and no air resistance, then NO force is needed to keep an object moving in a straight line at constant speed.  Check out Newton's first law of motion again.

Answer:

F = 0 N

Explanation:

Given that,

Mass of the hockey puck, m = 0.2 kg

Speed of hockey puck, v = 8 m/s

As the speed is constant. So, there is no change in the velocity. As a result, the acceleration of the hockey puck is 0. Force is given by :

[tex]F=ma[/tex]

Since, a = 0

F = 0

So, the amount of force needed to keep a 0.2 kg hockey puck moving at a constant speed of 8 m/s on friction less ice is zero newton.

oil and gas have relatively high heating values as compared to other locally available materials. they are also easy to burn as they are highly inflammable.

ignition takes less time due to this property.

Answer: C- 70%

Explanation:

Useful energy = 250J-75J = 175J

175J/250J*100= 70%

Efficiency should always be less than 1 or below 100% because every device wastes some energy. You committed a calculating error if you receive a result that is more than 1 or 100% Thus option C is correct.

Efficiency refers to how effectively a technology converts energy input into usable energy output. The percentage of energy delivered in beneficial ways determines a device's efficiency. Either a decimal or a percentage can be used to represent the efficiency.

Any efficiency can be determined by dividing the energy input by the energy output by 100%. This equation serves as a general representation of energy in the form of heat or power.

Therefore, Useful energy = 250J-75J = 175J  175J/250J×100= 70%
