What is electromagnetic radiation?Electromagnetic radiation is a type of energy radiation produced by the propagation of electromagnetic waves that are produced for natural as well as anthropogenic reasons. This radiation does not need any kind of medium to propagate. The electromagnetic wave has components of light as well as heat in them.
Different kinds of electromagnetic radiation have varied levels of energy for example solar radiation is also a form of electromagnetic radiation and gamma radiation is electromagnetic radiation with very high energy.
Most energy in the form of the light wave is produced by the Compact fluorescent lightbulb, therefore the correct option is D.

Typical Pressurized Water Reactors can produce 1100 to 1500
megawatts, or about _______
Joules/second.
Answer: about 1,100,000,000 to 1,500,000,000 Joules/second
Explanation:
1 MW (megawatt) = 1,000,000.00 J/s (joules per second)
1100(1,000,000) = 1,100,000,000
1500(1,000,000) = 1,500,000,000

How do you prove you know which object has more momentum without calculating it?
Answer:
The momentum of an object varies directly with the speed of the object.
Explanation:
Two objects of different mass are moving at the same speed; the more massive object will have the greatest momentum. A less massive object can never have more momentum than a more massive object.

A force of 500N Is applied to a steel wire of goss_sectional area 0.2m2 the tensele stress is a. 2.5x10 1nm-2 b. 1 0x102nm-2 c. 2.5x103nw-3 d. 1.0x103nm-2
Answer:
the tensile stress of the steel wire is 2.5 x 10³ Nm⁻².
Explanation:
Given;
applied force, F = 5000 N
cross sectional area of the steel wire, A = 0.2 m²
The tensile stress of the steel wire, is calculated as;
[tex]\sigma = \frac{F}{A} \\\\\sigma = \frac{500}{0.2} \\\\\sigma = 2500 \ N/m^2\\\\\sigma = 2.5 \ \times \ 10^3 \ Nm^{-2}[/tex]
Therefore, the tensile stress of the steel wire is 2.5 x 10³ Nm⁻².

On earth a bag of sugar weight 10N. on mars a bag of sugar weight 4N. suggest the weight of the sugar is different on earth and mars
Answer:
gravity
Explanation:
there eould be a different gravitational strenght on both of the planets causing it to weigh more, or less
In mars, the effect of gravity on the object is weaker compared to while on earth. This weakness is what causes the reduction in the weight of the bag of sugar while on mars.
We must understand that the mass of an object may differ depending on its location on the planet. This is due to the effect of gravity on the object.
Gravity is simply defined as any force which attracts an object towards the centre of the earth.
From the question given, we are told that the weight of sugar is 10N on the earth and 4N on Mars. This difference in their mass is attributed to the effect of gravity on the object.
In mars, the effect of gravity on the object is weaker compared to while on earth. This weakness is what causes the reduction in the weight of the bag of sugar while on mars.

A body of mass 1kg is attracted by the earth with a force which is equal to
Answer:
9.8N
Explanation:
Given the following data;
Mass = 1kg
We know that acceleration due to gravity is equal to 9.8m/s²
To find the force:
Force = mass * acceleration
Substituting into the equation, we have:
Force = 1 * 9.8
Force = 9.8N

A girl weighing 500 Newtons takes 50 seconds to climb a flight of stairs 18 meters
high at a speed of 0.36 m/s. Her power output vertically is-
Answer:
180Watts
Explanation:
Power = Force * distance/Time
Given
Force = 500N
Distance = 18m
Time t = 50secs
Substitute into the formula
Power = 500*18/50
Power = 10 * 18
Power = 180Watts
Hence her power output vertically is is 180Watts

3. Why is static electricity not useful as a power
source?
A. Because electrons aren't transferred in bursts of
static electricity
B. Because all energy is released at once in static
electricity
C. Because static electricity is not a real form of
electricity
D. Because static electricity only occurs in lightning
Static electricity is not useful as a power source primarily because it releases all of its energy at once rather than providing a continuous and controlled flow of electrical energy. The correct answer is B.
When static electricity is discharged, such as in a spark or a sudden discharge of stored charge, it happens in a rapid and uncontrolled manner, resulting in a brief burst of energy rather than a steady and sustained flow.
Power sources typically require a continuous and controllable flow of electrical energy to be useful for various applications. Static electricity, in its nature, does not provide this continuous flow but instead releases energy in an instantaneous manner. Therefore, it is not suitable for most practical power needs and applications.
Option A is not correct because electrons can be transferred in bursts of static electricity. Option C is not correct because static electricity is a real form of electricity, even though it has unique characteristics. Option D is not correct because static electricity can occur in various circumstances, not just in lightning.
Therefore, Static electricity is not useful as a power source primarily because it releases all of its energy at once rather than providing a continuous and controlled flow of electrical energy. The correct answer is B.

The first charge is pulling on the second. Is the second pulling on the first? Explain your reasoning
Answer:
law of action and reaction.
Explanation:
In Newton's three laws it is established that forces act in pairs, if one body interacts with another the second interacts with the first, this is the so-called law of action and reaction.
In this case, when the first load pulls on the second, the second pulls on the first, the two forces are not canceled because each one is applied to a different body.
Therefore the magnitude of the forces is the same, but the direction is opposite and each one is applied in a body
An electric force is an attractive or repulsive interaction. Newton's laws of motion define how it affects things, just like any other force. Yes, the second pulling on the first.
How does Newton's third law explain in terms of electricity?An electric force is an attractive or repulsive interaction between any two charged things. Newton's laws of motion define how it affects things, just like any other force.
The motion of objects under the influence of such a force or combination of forces is studied using Newton's laws.
The analysis generally starts with the creation of a free-body diagram in which the kind and direction of the various forces are represented by vector arrows.
Newton's laws of motion define how it affects things, just like any other force. Hence Yes, the second pulling on the first.

an atom with an atomic number of 12 and a mass number of 25 can best decided by which of these
Answer:
An atom that contains 12 protons

A sound wave produce by a chime 515 m away is heard 1.50 s later.What is the speed of the sound in air?
Answer:
the seed of the sound in the air is 343.3 m/s
Explanation:
The computation of the speed of the sound in the air is shown below:
As we know that
Speed = Distance divided by Time
So, here speed be 515m
And, the time is 1.50 second
So, the speed of the sound is
= 515m divided by 1.50 seconds
= 343.3 m/s
hence, the speed of the sound in the air is 343.3 m/s
