Explanation:
An oil drop (m = 1.6 x 10-16 kg) is suspended between plates separated by 1.8 cm. The voltage
across the plates is 125 V. Is this possible?
Answer:
E = V / d 125 V / .018 m = 6940 V/m electric field
F = E Q force on Q due to E
F = E n e where n is the number of electrons in Q
m g = E n e
n = m g / E e where n is the number of electrons e needed to support drop
n = 1.6 * 10E-16 * 9.8 / (6940 * 1.6 * 10E-19)
n = 1.41
Since n needs to be an integral number of charges, the drop would
not be suspended (motionless under these conditions).

In your own words, explain the difference between a conductor and an insulator.
(4th grade)
Answer: There are different kinds of conductors, most notably electrical and thermal conductors. But they are often inclusive of each other (electrical conductors are typically good thermal conductors). A conductor transmits something through its body with high efficiency while an insulator does not transmit very well. In the case of electricity, a conductor transmits electrical energy between two points while an insulator blocks the flow of electricity. Two examples of conductors are copper and silver. Two examples of insulators are wood and styrofoam.

Which action is an example of a service provided by an organization that receives charitable donations?
A. researching vaccinations
B. advertising new medications
C. contracting to install waiting area carpeting
D. selling hospital supplies for a privately owned company
Answer:
A
Explanation:
Source: Trust me bro
Giving is a kind deed. Giving back to people in need allows you to grow personally and gives you a higher sense of fulfilment. It also makes you feel good to serve others. Thus, option A is correct.
What charitable donations in researching vaccinations?Donations to non-profit organizations are considered charitable contributions. Donations may take the form of cash, non-monetary goods, in-kind services, or volunteer time. According to IRS rules, the donation may be tax-deductible.
If you itemize your deductions, you may deduct gifts of money or other property provided to qualifying organizations for charitable purposes. In general, you can deduct up to 50% of your adjusted gross income, but in some circumstances, there are 20% and 30% limitations.
Therefore, A contribution is a gift given to a cause, humanitarian organization, or charity. A donation can come in many ways, such as cash, alms, services, or tangible objects like furniture, toys, food, or automobiles. A donation could meet a demand for transplantable organs or blood.

How is spring force different in a compressed spring versus a stretched spring?
Answer:
if you pull on a spring and stretch it, then you do work. that's bc you're applying a force over a displacement. your pull is the force and the amount that you stretch the spring is the displacement. a spring can be stretched or compressed.

What type of energy comes from the motion of tiny particles of matter?
Answer: Heat
Explanation: All matter is made of tiny particles called atoms, molecules and ions. These tiny particles are always in motion – either bumping into each other or vibrating back and forth. It is the motion of particles that creates a form of energy called heat (or thermal) energy that is present in all matter

Which of the following is a correct example of the current in a light bulb?

In the lab, a student is investigating the effects of texting and driving on reaction time. A
student determines his/her reaction time by having a friend release a meter stick at
random intervals while the driver sends text messages. The student, on average,
catches the meter stick after it has traveled 0.64 m.
How far will the student
travel in a car moving at 25 m/s horizontally before reacting?
9.0 m
0.64 m
69 m
We know that we can write the speed of something as the quotient between the distance it moves and the time it takes to move that distance.
speed = distance/time
Using this, we will find that the correct option is the first one, 9.0 m
The information we know is:
The student, on average, catches the meter stick after it has traveled 0.64m
We need to transform this into time.
Assuming that the meter stick is just released, the only acceleration it will have is the gravitational one, so we have:
a(t) = -9.8m/s^2
To get the velocity of the stick we need to integrate over time, as the it is just released, it will not have initial velocity, thus the constant of integration is zero:
v(t) = (-9.8m/s^2)*t
To get the position equation we need to integrate again, and as the initial position is relative, we can define it as zero, so again the constant of integration is zero:
p(t) = (1/2)(-9.8m/s^2)*t^2
p(t) = (-4.9 m/s^2)*t
We know that the student catches the stick after it traveled (downwards) 0.64m
Then we need to solve:
-0.64m = (-4.9 m/s^2)*t
√[(-0.64m)/(-4.9m/s^2)] = t = 0.36s
So the reaction time of the student is 0.36 seconds.
Now we can use the first equation:
speed = distance/time
And rewrite it as:
distance = speed*time
So if the car moves at 25m/s and the student needs 0.36 s to react, the distance that he/she will move in that time frame is:
d = (25m/s)*0.36s = 9.0m
So the correct option is the first one.

why displacement has a fixed direction and change in position
The position of an object is where it sits on the number line. When the object moves to another position, its displacement is the second position minus the first position.
Δ x = x2 − x1
The word displacement implies we keep track of which way the movement occurs. In one dimension the direction is indicated by the sign: negative if to the left and positive if to the right. The word distance means how far the object moves regardless of direction. It is always positive and is equal to the absolute value, or magnitude, of the displacement.
If one follows the rule of always subtracting the first position from the second, the sign always works out to be positive if the displacement is to the right and negative if the displacement is to the left.
Consider any ocean wave, what is the relationship between an ocean wave and the energy of that wave?
A) Wave energy decreases as the wave moves closer to the shore
B) The greater the wavelength, the more kinetic energy the wave has
C) Wave energy is directly proportional to the amplitude of the wave
D) Wave energy increases with frequency and decreases with wavelength
Answer:
C.
Explanation:
Wave energy is directly proportional to the amplitude of the wave. It is a square function.. double the amplitude (wind/solar power picks up) the energy in the ocean wave is quadrupled.
Wave energy is directly proportional to the amplitude of the wave. Therefore, option C is correct.
What is wave energy?Waves of heat, light, sound, and water carry a variety of energies. All types of energy can be converted into work because energy is defined as the capacity to perform work. The movement of an object in the direction of the force acting on it is referred to as work in science. When they move items, waves do really work. This process is evident when sand is carried or large logs are moved across ocean basins.
Work can also be transformed into the acoustic energy produced when waves crash on the coast. The potent force of waves can also be used to move generator components and generate electricity.
A wave's energy content is influenced by its height, wavelength, and breaking point in addition to other factors. When waves of identical wavelengths fall back to sea level, the wave with the greater amplitude will release more energy than the wave with the lesser amplitude. Therefore, option C is correct.
