what is electrostatic induction
Answer:
See Below
Explanation:
It is a change in the distribution of electric charge on one object because of the influence a nearby object that has an electric charge. So if an object with a negative charge is brought near to a neutral object, the neutral object will alter itself so that one side becomes more positive and the other side becomes more negative.
Electrostatic induction occurs whenever any object is placed in an electric field.
In which of the following cases of motions, the distance moved and the magnitude of the displacement are equal?
If the car is moving on a straight road
If the car is moving in circular path
The pendulum is moving to and fro
The earth is moving around the sun
Answer:
answer is number (a) If the car is moving on a straight road....
Explanation:
The distance moved and magnitude of displacement are equal only in the case of motion along a straight line. Because displacement is the shortest path between initial and find path. So, for car moving on straight road, distance moved and magnitude of displacement are equal.

Which action is due to field forces
Answer:
:)
Explanation:
Raindrops fall on the earth due to gravitational field force. When two magnets come closer to each other, they will either attract or repel each other, which is magnetic field force examples. Without any physical contact, iron pins get attracted towards the magnet as a field force.

light waves are first transmitted through the ________ at the front of the eye and enter an opening called the ________ before shining onto the retina.
The transmission of light waves is usually done through cornea of the eyes, then move through another opening which is regarded as pupil before it will get to the retina.
Light waves can be regarded as moving energy which contains microscopic particles known as photons. The vision of the eye can be completed through the light wave passing through the components of the eyes and this process goes thus;Light will move through the (cornea) which is situated at the front area of the eyes into lens. Then both the cornea and the lens give room for the focusing of the light rays to the retina which is situated at the back of the eye .Then through the help of the cells in the retina, the light will be absorbed and then be converted to electrochemical impulses and then transfer it to the brain as well as optic nerve.Therefore, light wave are form of tiny microscopic particles.

What conclusion does the student most likely make based on this data?
Answer:
O Tightly packed particles in solids slow down the light waves; however, sound waves make particles bounce into each other, so they travel faster in solids.
Explanation:
In the data the student collected, it showed that when the atmosphere is thicker, it slows down the light. With sound however, the sound travels better in thicker stmosphere or solid, than thin air, or steam.

which transition will lead to the emission of light with longer wavelength?
Answer:
(C)
Explanation:
its C ok
The transition that will lead to the emission of light with longer wavelengths is n = 3 to n = 2. The correct option is c.
What is the emission of light?The largest energy change, and hence the shortest wavelength, x nm, would occur during the transition from the highest to the lowest energy levels. When an electron moves from the n = 5 to the n = 1 level, an atom emits yellow light.
The Bohr model of the atom is named for Niels Bohr, who created a model of the electron in which electrons were arranged into energy levels using observations of atomic spectra.
Because electrons can only exist in the energy levels and not in the intermediate states, they must absorb or emit a certain amount of energy to change energy levels.
Therefore, the correct option is c. n = 3 to n = 2.

Question 5 (1 point) true or false: Balanced forces acting on an object result in constant velocity True False
Answer:
false
Explanation:
By Newton's first law (An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force), neither speed nor direction change. Our force is balanced.
Balance forces could happen when the object is at rest but not all the time. A balance force is when a object is being push in opposite directions, which would cause the object to stay still or move at a constant speed. Which would mean that balance force could take place when a object is moving or when a object is at rest.

Henry ran a 100 m race. Use the graph to answer the following:
a. How long did it take for Henry to run 100 m?
b. What is Henry's average speed over the race?
Using the graph, which describes how Henry ran the 100m race;
a) It takes Henry 20seconds to run 100m
b) Henry's average speed over the race is; 5m/s.
According to the linear graph which describes the distance ran by Henry during the 100m race as a function of time.
a) Since the distance from start ran by Henry is plotted on the vertical axis, and the time is plotted on the horizontal axis;
To determine how long it took Henry to run 100m; The point corresponding to 100m is traced downward from the line of the graph and we find out that;
It takes Henry 20seconds to run 100m
b) Henry's average speed over the race is simply;
The slope of the distance-time graph.
Therefore,
Average speed = (100-0)/(20-0)Average speed = 100/20Average speed = 5m/s.Therefore, Henry's average speed over the race is; 5m/s.

Sue and Jenny kick a soccer ball at exactly the same time. Sue’s foot exerts a force of 68.9 N to the north. Jenny’s foot exerts a force of 85.4 N to the east.
a) What is the magnitude of the resultant force on the ball?
Answer in units of N.
Explanation:
the magnitude of the resultant force =
√(68.9² + 85.4²)
=√(4,747.21 + 7,293.16)
=√12,040.37
= 109.7 N
»Sue's style feet (north) = 68.9N
»Jenny style feet (East) = 85.4N
So, the resultant force on the ball is
= √(68.9² + 85.4²)
= √(4,747.21 + 7,293.16)
= √(12,040.37)
≈ 109.72N✅
