Which type of mirror curves outward?
Which type of mirror always has an image that is smaller than the object?
Which type of mirror is used to focus light rays?
Which type of mirror has a flat surface?
Explanation:
1. Convex mirror is curved outward.
2. Convex mirror forms an image that is smaller than the object.
3. Concave mirror is used to focus light rays. That's why it is also known as a converging mirror.
4. Plane mirror has a flat surface. It forms the same size of the image as that of the object.
The reflective surface of a convex mirror, also known as a curved mirror, bulges toward the light source.
Thus, A curved mirror's surface can be convex, meaning it bulges outward, or concave, meaning it bulges inward. Since a convex mirror reflects light outward, it cannot be utilized to concentrate light.
Because the focus and center of curvature are fictitious positions inside the mirror and are therefore unreachable, convex mirrors or curved mirrors always produce a virtual image.
As a result, convex mirror images cannot be projected onto a screen. The picture is also smaller than the projected object, but it grows larger as it goes closer to the convex mirror.
Thus, The reflective surface of a convex mirror, also known as a curved mirror, bulges toward the light source.

In the diagram, q1 = +6.60*10^-9 C and q2 = +3.10*10^-9 C. Find the magnitude of the total electric field at point P. pls help?
Answer:
|E(t)| = 1258,46 [N/C]
α = 67,5⁰ (angle with respect x-axis)
Explanation:
E(t) Electric Field is a vector, so we need to determine module and direction
E(t) = E(q₁) + E (q₂) Where E(q₁) and E (q₂) are electric fields due to electric charge q₁ and q₂ respectively.
E(q₁) = K * q₁/ (d₁)² K = 9 *10⁹ [N*m²/C²] d₁ = 0,350 m
E(q₁) = 9 *10⁹ * 6,6*10⁻⁹ / 0,1225 [N*m²/C²] *C/m²
E(q₁) = 484,9 [N/C]
E(q₂) = 9 *10⁹ * 3,1*10⁻⁹ / 0,024025
E(q₂) = 1161,29
Then
|E(t)| = √ |Eq₁|² + |Eq₂|²
|E(t)| = √ ( 484,9)² +( 1161,29)²
|E(t)| = √ 235128 + 1348594,46
|E(t)| = 1258,46 [N/C]
And tanα = 1161,29/484,9 tanα = 2,395 α = 67,5⁰

Contrast electron movement within conductors and insulators.
Answer:
Electrons surrounding a nucleus are attracted to the protons within it because electrons and protons have opposite charges. Electrons closest to the nucleus are attracted with such a force that they can’t escape from the atom. These electrons tend to shield the protons from electrons that are farther away because electrons have the same charge and repel each other. Electrons that are farther away have less attraction to the protons within the nucleus and are more likely to be detached from the atom.
Electrons can be transferred from atoms of one body to atoms of another body through friction. This can occur when one body is rubbed against another or when a liquid flows across a solid. In either case, one body may be given a positive charge while the other body is given a negative charge of the same magnitude. Both charges are developed at the same time. Electrons can also be transferred from one body to another when a charged body comes into contact with an uncharged body. The electrons move in the direction that will equalize the charges; thus, the uncharged body will be given the same charge as the charged body.
Free electrons move from points of negative charge to points of positive charge. When these electrons move freely from one point to another with little resistance, the material they’re traveling through is said to be a conductor. Conductors have a large number of free electrons. Insulators, on the other hand, have very few free electrons and offer great resistance to the movement of these electrons. Electric charges produced on one end of a body composed of insulating materials will most likely not spread throughout the body. In a conductor, this charge would spread throughout the entire body. Metals are generally conductors; oils, rubber, air, porcelain, and plastics are good insulators.
Lightning is produced by the rapid transfer of free electrons when one of the following conditions exist:
One part of a cloud is positively charged and a neighboring part of the same cloud is negatively charged.
A positively charged cloud comes near a negatively charged cloud.
A cloud with either a positive charge or a negative charge comes near the earth.
Explanation:
Free electrons are abundant in conductors. Conversely, insulators provide a high level of barrier to the movement of these free electrons, since they have some of them. In a body made of insulating materials, electric charges generated on one end are likely to remain localized there.
What are conductors?Electrons can move freely between particles when they are in conductors, which are substances. The charge can be transported across the whole surface of an object constructed of a conducting substance.
Because distant electrons have the same charge as these nearby ones and resist one another, these electrons usually act as a shield for protons. Further distant, electrons are less attracted to the nucleus's protons and are therefore more prone to break away from the atom.
Free electrons migrate from negatively charged to positively charged locations. The substance these electrons are passing through is referred to as a conductor when it allows them to go easily from one location to another with little resistance. Electrons are abundantly free in conductors.
A body made of insulating materials will likely not conduct electricity when it generates charges on one end. This charge would permeate the entire body of a conductor. Oils, rubber, air, porcelain, and plastics are effective insulators while metals are typically conductors.

In the diagram, q1= +8.0 C, q2= +3.5 C, and q3 = -2.5 C. q1 to q2 is 0.10 m, q2 to q3 is 0.15 m. What is the net force on q2? Label sign for charges (+ or -). (Unit = N). pls help?
Answer:
f(t) = 28,7 [N]
Explanation: IMPORTANT NOTE: IN PROBLEM STATEMENT CHARGES ARE IN C (COULOMBS) AND IN THE DIAGRAM IN μC. WE ASSUME CHARGES ARE IN μC.
The net force on +q₂ is the sum of the force of +q₁ on +q₂ ( is a repulsion force since charges of equal sign repel each other ) and the force of -q₃ on +q₂ ( is an attraction force, opposite sign charges attract each other)
The two forces have the same direction to the right of charge q₂, we have to add them
Then
f(t) = f₁₂ + f₃₂
f₁₂ = K * ( q₁*q₂ ) / (0,1)²
q₁ = + 8 μC then q₁ = 8*10⁻⁶ C
q₂ = + 3,5 μC then q₂ = 3,5 *10⁻⁶ C
K = 9*10⁹ [ N*m² /C²]
f₁₂ = 9*10⁹ * 8*3,5*10⁻¹²/ 1*10⁻² [ N*m² /C²]* C*C/m²
f₁₂ = 252*10⁻¹ [N]
f₁₂ = 25,2 [N]
f₃₂ = 9*10⁹*3,5*10⁻⁶*2,5*10⁻⁶ /(0,15)²
f₃₂ = 78,75*10⁻³/ 2,25*10⁻²
f₃₂ = 35 *10⁻¹
f₃₂ = 3,5 [N]
f(t) = 28,7 [N]

Answer: A mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium. While waves can move over long distances, the movement of the medium of transmission the material is limited. Therefore, the oscillating material does not move far from its initial equilibrium position. Mechanical waves transport energy.

A TV set shoots out a beam of electrons. The beam current is 10A. How many electrons strike the TV screen in a minute.
Answer:
600 mC
Explanation:
The charge of an electron is 1.6 x 10-19C so for a current with 10 mA, the charge going to screen in one second is 10 mC
so number of electrons, n = (10 x 10-3)/(1.6 x 10-19) = 6.25 x 1016 so in a minute the charge is 10 * 60 = 600 mC
Answer:
Total charge, q = It = 10 A x 60 s = 600 C
We know that, q = ne
So no. of electrons, n = q/e = 600 / (1.6×10-19) = 375x1019

Answer:
0.0025 kilograms
Explanation:
There are a 1000 grams in 1 kilogram, so that means that there are
0.0025 kilograms in 2.5 grams.
Answer:
Below
Explanation:
● 1 kg = 1000 g
Divide both sides by 1000
● 1/1000 kg = 1000/1000 g
● 0.001 kg = 1 g
Multiply both sides by 2.5
● 2.5 g = 0.001 × 2.5 kg
● 2.5 g = 2.5 × 10^(-3) kg
● 2.5 g = 0. 00 25 kg

What GDP is generated by the service industry?The service sector, often known as the tertiary sector, makes up the third tier of the three-sector economy. Instead of creating products, this sector provides training, consulting, and maintenance and repairs.
The GDP of the nation is significantly impacted by the service sector. Through trade in services, it not only generates many jobs, but also significantly improves the country's economic performance.
Therefore, 70% of GDP is made up of consumer expenditure. The retail and service sectors are important to the American economy.
