The earth gravity field strength in the south pole is less than the north pole. Explain
Answer:
Your weight is the combination of all the large-scale, long-term forces on your body. While the earth's gravity is by far the strongest large-scale force, it is not the only one. What you experience as "something pulling you down" is actually the total of all the forces and not just gravity. The four dominant large-scale,

Which two options are reasons that electromagnetic waves are effective for
use in communication devices?
A. The entire electromagnetic spectrum can be used.
B. They can travel through matter and through space.
C. Both gamma rays and X-rays can be used.
D. They can carry information for long distances without wires.
They can travel through matter and through space.
What is Electromagnetic waves?Electromagnetic radiation is one of the many ways that energy travels through space. The heat from a burning fire, the light from the sun, the X-rays used by your doctor, as well as the energy used to cook food in a microwave are all forms of electromagnetic radiation.
While these forms of energy might seem quite different from one another, they are related in that they all exhibit wavelike properties.
The electromagnetic spectrum is a taxonomy of electromagnetic waves that groups them according to their varied wavelengths and frequencies.
Therefore, They can travel through matter and through space.

The crane pull up the mass with 1150 N. Find the acceleration the
mass.m = 100kg
Kren tersebut menarik naik jisim itu dengan 1150 N. Cari daya
paduan pada jisim itu
[use gravitational acceleration, g = 9.81 m s?]
Answer:
-1.69 m/s²
Explanation:
We are told the crane pulls up the mass with a force of 1150 N.
This means it is in an opposite direction to gravity and thus acceleration(a) is negative.
Now, the gravity is acting downwards, thus, total force is;
F = mg - ma
1150 = 100(9.81 - a)
Divide both sides by 100 to get;
11.5 = 9.81 - a
a = 9.81 - 11.5
a = -1.69 m/s²

1) Kinetic energy of an object is the measure of the work an object can do by the virtue of its motion.
For Example : A river flowing at a certain speed comprises kinetic energy as water has certain velocity and mass.
2) Potential energy is the energy held by an object because of its position relative to other objects, stresses within itself, its electric charge, or other factors.
For Example : A child at the top of the slide
3) KINETIC ENERGY
Kinetic energy is the kind of energy present in a body due to the property of its motionIt can be easily transferred from one body to anotherIt is relative with respect to natureFlowing water is one of the examples of kinetic energyPOTENTIAL ENERGY
Potential Energy is the type of energy present in a body due to the property of its stateIt is not transferableIt is non-relative with respect to natureWater present at the top of a hill is an example of potential energy(make sure to draw a table and write them separately)

Tonks changes her hair color for a party with a red color rinse. The next day, she washes the color out of her hair and it returns to its original brown color. Has a chemical change occurred? Explain your answer.
Answer: No , a chemical change has not occured as it was easily reversed.
Explanation:
Chemical change is defined as a change in which rearrangement of atoms take place and leads to formation of new substances. It can only be reversed with the help of a chemical reaction.
Physical change is defined as a change which leads to change in shape, size or state of the substance changes. No new substance is formed.It can be easily reversed.
As the hair colour was washed out and returned to its original brown colour, it was a physical change.
ignoring friction, what is the mass of an object accelerating at 1.8m/s2 to which an unbalanced force of 42 Newtons has been applied?
Explanation:
Newton's second law:
F = ma
42 N = m (1.8 m/s²)
m = 23 kg
An object accelerating at 1.8 m/s² to which an unbalanced force of 42 Newtons has been applied, mass of object is 23 kg.
What is force?A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.
Given in the question the mass of an object accelerating at 1.8 m/s² to which an unbalanced force of 42 Newtons has been applied is ,
Using Newton's second law force is given as
F = ma
42 N = m (1.8 m/s²)
m = 23 kg
An object accelerating at 1.8 m/s² to which an unbalanced force of 42 Newtons has been applied, mass of object is 23 kg.

Write down three facts you about motion
Write Them in complete sentences
Answer:
Kindly check explanation
Explanation:
Motion of an object could be explainwd as how a body changes position over time. Some of the proven facts about motion are stated by Sor Isaac Newton, named the Laws of motion :
1. A body will continue on it's state of rest or uniform motion in a straight line unless acted upon by a force to make it act otherwise.
2.) The second law explains that the force acting in an object is a product of the mass and acceleration.
Force = mass * acceleration due to gravity
3.) To every action, there is an equal and opposite reaction.
That is ; applied force in the positive direction on an object, yield an equal amount of force in the opposite direction.

500cm3 of water is to be jeated from room temperature 28oc to 100oc in order to prepare ahot cup pf coffee. What os the minimum heat required
Answer:
The minimum heat required is 171626 joules.
Explanation:
By First Law of Thermodynamics, the amount of heat ([tex]Q[/tex]), in joules, is equal to the change in internal energy of water. The minimum heat required is the sensible heat necessary to heat up the water. That is:
[tex]Q = \rho\cdot V \cdot c\cdot \Delta T[/tex] (1)
Where:
[tex]\rho[/tex] - Density of water, in kilograms per cubic meter.
[tex]V[/tex] - Volume of water, in cubic meters.
[tex]c[/tex] - Specific heat of water, in joules per kilogram-degree Celsius.
[tex]\Delta T[/tex] - Change in temperature, in degrees Celsius.
If we know that [tex]\rho = 1000\,\frac{kg}{m^{3}}[/tex], [tex]V = 5\times 10^{-4}\,m^{3}[/tex], [tex]c = 4186\,\frac{J}{kg\cdot ^{\circ}C}[/tex] and [tex]\Delta T = 82\,^{\circ}C[/tex], then the minimum heat required is:
[tex]Q = 171626\,J[/tex]
The minimum heat required is 171626 joules.
