When a star is undergoing nuclear fusion what type of radiation will be found?
Answer:
I think the correct answer would be the third option. As the elements around the star begins to emit more and more electromagnetic radiation, the rocky materials are pulled in by the electromagnetic radiation. They are being drawn closer to the star and there would be a very high chance of a nuclear
Explanation:
Decide whether these are true or false. Type out the whole sentence in the space and type a "T" beside the letter. Retype the sentences that are not correct. A. An object has acceleration if its velocity is changing. B. Force is measured in joules. C. Gravity is a force.
Answer:
1. True.
2. False.
3. True.
Explanation:
A. True: An object has acceleration if its velocity is changing. In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.
B. False: Force is measured in joules. Force is a product of the mass of an object and its rate of acceleration. Thus, force is actually measured in Newton.
C. Gravity is a force. Gravity is considered to be a universal force of attraction which acts between all objects that has both mass, energy and occupy space. Therefore, it acts in such a way as to bring objects together.

Explain how that energy converts itself from POTENTIAL to KINETIC energy.
Answer:
Potential energy can transfer into other forms of energy like kinetic energy. Kinetic energy is energy an object has because of its motion.
Explanation:
The ball was released, as the ball moves faster and faster toward the ground, the force of gravity will transfer the potential energy to kinetic energy.

The light is in one direction after passing through a polarizer
True or false
Answer:
Light propagating in a plane that makes a 0 degree angle with the polarizer will pass through and all other planes will only pass the component of the vector that is in line with the polarizer. What the image suggests, and other images like the second one, is that the light is now all propagating parallel to a single plane
Explanation:
hope this helps
Answer:
true
Explanation:
a polarizer allows only light of a specific wavelength to pass through

A zebra drinks from a watering hole and is ambushed by a crocodile. What's more important and why: the zebra having a high maximum speed or a high acceleration?
Answer:
before this type of attack, high acceleration is the most important thing.
Explanation:
As the zebra is ambushed by the crocodile the most important thing is a quick reaction, in this attack the most likely is that the crocodile is in the water so it cannot run after the zebra.
Consequently, before this type of attack, high acceleration is the most important thing.

An 80 kg diver jumps from a 10 m high platform. What is the gravitational potential energy of the diver right before they jump (top of platform)
Answer:
0 Joules.
Explanation:
Given the following data;
Mass = 80kg
Height = 10m
Gravitational potential energy (GPE) is an energy possessed by an object or body due to its position above the earth.
Mathematically, gravitational potential energy is given by the formula;
[tex] G.P.E = mgh[/tex]
Where;
G.P.E represents potential energy measured in Joules.
m represents the mass of an object.
g represents acceleration due to gravity measured in meters per seconds square.
h represents the height measured in meters.
We know that acceleration due to gravity is equal to 9.8m/s²
But since we're determining the gravitational potential energy just before the driver jump, the height would be zero (0) meters.
Gravitational potential energy= mgh
Gravitational potential energy = 80*9.8*0
Gravitational potential energy = 0 Joules.
This ultimately implies that, if an object or body hasn't moved (jumped) from its reference point, its gravitational potential energy would be equal to zero.
A car covers 400m distance in 50 sec find it's speed?
Answer:
[tex]\boxed {\boxed {\sf 8 \ m/s}}[/tex]
Explanation:
Speed is equal to distance over time.
[tex]s=\frac{d}{t}[/tex]
The distance is 400 meters and the time is 50 seconds.
[tex]d= 400 \ m \\t= 50 \ s[/tex]
Substitute the values into the formula.
[tex]s=\frac { 400 \ m }{ 50 \ s}[/tex]
Divide.
[tex]s= 8 \ m/s[/tex]
The speed of the car is 8 meters per second.
What unit is used for speed?
1. m/s
2. S
3. m/s2
4. m
Answer:
The unit of speed is m/s.
5. Relationships in a community can be cooperative or competitive.
True
False
Answer:
True
Explanation:
is the correct answer
Answer:
This is True
Explanation:
Communities cooperate by simply co-existing and working together to benefit the community and offering their goods and services. Some programs in a community offer social work, like volunteering and charities, which help people in need in a community.
They can also be competitive because there are lots of the same goods and services offered throughout the city, so businesses have to compete for sales to attract consumers in the communities.

What is one reason that electromagnetic waves are used in long-distance communication?
A. They travel rapidly.
B. They move matter easily
C. They do not lose energy over long distances.
D. Informatioŋ can be encoded in the wave speed.
One reason that electromagnetic waves are used in long-distance communication is, that they do not lose energy over long distances. So Option C is correct
What are electromagnetic waves ?Electromagnetic waves are a type of wave that consists of oscillating electric and magnetic fields. They are propagated through space or through a material medium, and they have the ability to travel through a vacuum, which is the absence of matter. Electromagnetic waves have a wide range of frequencies, which determines the type of electromagnetic wave. The most familiar types of electromagnetic waves include radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.
One of the property of the electromagnetic waves is that they do not lose energy over long distances.

What's the Genotype for these? If your answer is something off-topic I ShAlL rEpOrT iT u.U
Pick any free letter for each trait. For example, "A" for the dominant allele and "a" for the recessive allele for the number of arms. Assuming complete dominance, the genotype for the dominant trait will always have at least one "capital" allele, so a creature with 2 arms would have genotype either AA (homzygous dominant) or Aa (heterozygous), while a creature with the recessive trait of having 4 arms will always be homzygous recessive with genotype aa.

Why is average global temperature the most important value when talking about climate change?
Answer:
The most important number's formal name is "equilibrium climate sensitivity," and it's meant to represent the new equilibrium in surface temperatures after a change in the amount of the Sun's energy trapped here on Earth rather than radiated back to space.
Explanation:
please give me brain list and follow
The average global temperature is the most important value when talking about climate change because the Earth's temperature is increasing day by day due to the trapping of the Sun's light energy.
What is temperature?The temperature is the degree of hotness or coldness of the object.
The equilibrium climate sensitivity is the equilibrium in Earth's surface temperature. After the Sun's trapped energy is reduced, the climate changes accordingly.
Thus, the average global temperature is the most important value when talking about climate change because the Earth's temperature is increasing day by day due to the trapping of the Sun's light energy.

How does convection play a role in hurricanes
Answer:
Convection is what keeps the hurricane going in till the storm hits land.
Explanation:
Convection is the warm, moist current that rises above sea level and as it cools into water vapor it releases energy which a hurricane runs on. Once the hurricane hits land it continues to lose energy to keep it going because there's no convection from the sea currents rising above sea level to release energy.

Plssss help———what is the difference between the weight of an object and the mass of an object? (Needs to be 4-5 complete sentences)
The mass of an object is a measure of the object's inertial property, or the amount of matter it contains. The weight of an object is a measure of the force exerted on the object by gravity, or the force needed to support it. The pull of gravity on the earth gives an object a downward acceleration of about 9.8 m/s2.
