what is electrostatic condition?
Have you ever wondered why you experience a jolt upon contacting a doorknob? Deciphering these situations will teach you about the idea of electric charge. Two symbols, "+" and "-," can be found on batteries when they are analyzed. This is because the transmission of positive and negative charges occurs at these two ends.
The study of electric charges at rest is done by the science of electrostatics (static electricity).
The ability of some materials to collect light particles after rubbing, such as amber, has been recognised since classical times. Thus, the term "electricity" has its roots in the Greek word for amber, v (lektron). The forces that electric charges apply to one another give birth to electrostatic phenomena. Coulomb's law explains these types of forces.

analyze will pushing on a car always change the cars mechanical energy ?
Pushing on a car will not change cars mechanical energy because it does not create mechanical energy.
Mechanical energy is the energy of either an item in motion or the energy that is saved in object via their position. Mechanical strength is also a driving force of renewable strength.
There are types of mechanical energy: Potential energy and Kinetic energy. Combined, the sum of the 2 is called the overall mechanical power. Mechanical power is countless in nature.
Advantages of Mechanical energy are that this energy source does not not run out and can also be transformed into different types of power. Disadvantages of mechanical energy is that the machines that permit you to have the benefits of mechanical energy can create protection issues and also grow to be worn out and costly to fix.

(a) Draw free-body diagrams for mass M and mass m. (b)
Calculate the magnitude of the acceleration of the system.
(c) Calculate the tension in the string.
The magnitude of the acceleration of the system is equal to 1.96 m/s². The tension in the string is equal to 4.70 N.
What is Newton's second law of motion?
Newton's 2nd law of motion described the force acting on an object as equal to mass (m) times the acceleration (a) of that object.
The mathematical relation can be shown as follows:
F = ma
Given, the mass, m = 0.40 Kg and the mass M = 0.60 Kg
From newton's second law: Mg - T = Ma ...........(1)
Similarly, T - mg =ma ...............(2)
By adding both equations, we get:
(M - m)g = (M + a)a
(0.60 - 0.40) (9.8) = (0.60 + 0.40) a
a = 1.96 m/s²
The tension in the string can be determined as:
Mg - T = Ma
(0.60) (9.8) - T = (0.60) × 1.96

114.0 g of water is heated using 67.0 W of power, with perfect efficiency. How long will it take to raise the temperature of the water from 15° C to 25° C?
Water will take a time of 71.2 seconds to raise the temperature of the water from 15° C to 25° C.
What is the specific heat capacity?The specific heat capacity can be demonstrated as the quantity of heat needed to increase the temperature in one unit of material by one degree celcius.

Suppose you have a barometer with mercury and a barometer with water. How does the height hwater compare with the height hmercury?.
The heaviest liquid is mercury. In order to equalize the air pressure, it only climbs 76 cm. Water will rise to a 13.6 because it is 13.6 times lighter than mercury. By a factor of 13.6, mercury is 13.6 times denser than water.
Therefore, the barometer's height would be 13.6 times higher if water were employed in place of mercury. Since water expands when it freezes, the glass tube would be broken.
Because of its high density, mercury is frequently employed in barometers, allowing for a column height that is appropriate for measuring atmospheric pressure. For example, a mercury barometer would need to be 13.6 times taller than a water barometer to measure the same change in pressure.
This is the primary justification for using mercury in thermometers. Mercury will provide accurate readings in comparison to water since it lacks the condensation property that water possesses. Mercury can be used to measure both negative and positive temperatures, whereas water cannot be used to measure either.

Resultant force: If two or more forces are acting at a certain point, their resultant force would be defined as the force that when applied at that same point, it will have the exact same effect like the two independent forces acting together.
Fx = F cos Ф
Fx = 100 × cos 65 degree (Cos 65 degree = 0.52)

What is a balloon car?
For balloon-powered car, the contracting balloon pushes the air in the balloon backwards. That means the air in the balloon is pushing balloon forwards. The balloon is joined to car, so the car rolls. The motion is nothing to do with pushing on the air behind car.
There are two main forces acting on balloon rocket car: Friction and Air resistance. The friction force is resistance between two objects sliding against each other. While building your car identify places where objects will be rubbing against each other creating friction. In order to get car to move, we need an unbalanced force. In other words, the force of air coming out of balloon must overcome the forces acting on the car. We will want to reduce friction and air resistance to help your car move.In the case of balloon car, the action is the air rushing out of the balloon, pushing against air behind the car. The opposite or equal reaction is that the air behind car pushing against the car with the same force, causing the car to propel forwards.The weight of car is too great and nothing moves: As the car weight increases, friction between axle and straw, wheel and axle, and wheel and floor increase.

b) Is the value of an electric field E the same for both particles if we want it to make the particles move following a straight-line trajectory? Why?
c) What’s the kinetic energy change before and after applying the electric field?
Data: Proton mass is, approximately, 1836 times electron’s mass.
When E depends on the strength of the magnetic field and velocity, the strength of the electric field must also be the same to maintain a straight-line motion without deviating from it.
What is kinetic energy?The energy that an object has because it is moving is determined by the initial energy in physics. It is defined as the amount of effort required to accelerate an object of known weight from resting to its specified velocity. The body keeps its kinetic energy after gaining it during acceleration, barring speed changes. When slowing from its current pace to a point of rest, the body expends the same amount of energy.
(a)
The magnetic field is on the page and the image is attached.
(b)
The magnetic force must be balanced with force due to the electric Field.
Eq = qvB sinθ
Eq = qvB sin 90
E =vB
(c)
The kinetic energy of the particle with velocity v and mass m,
KE = 1/2 mv²
The proton's kinetic energy is 1836 times more than that of the electron since it is more heavy than it is.
The shift in kinetic energy will then be equal to zero if there is no increase in velocity between before and after the electric field is applied.

A guitar string of length 30 cm and stretched under a tension of 78 n has a certain fundamental frequency. How long would a pipe, open at both ends, need to be to play the same fundamental frequency? a 15-cm long piece of the guitar string has a mass of 0. 4 g. The speed of sound in air is 340 m/s.
0.6 m long would a pipe, open at both ends, need to be to play the same fundamental frequency .
Frequency, in physics, the number of waves passing through a fixed point in a unit of time. Also, the number of cycles or oscillations per unit time experienced by an object in periodic motion. An object in periodic motion is said to undergo a cycle or oscillation after returning to its original state through a series of events or positions. See also angular velocity. A simple harmonious movement.
The period or time interval required to complete a cycle or oscillation is 1/2 second, then the frequency is 2/second. If the period is 1/100 hour, the frequency is 100 per hour. In general, frequency is the reciprocal of duration or time interval. That is, frequency = 1/duration = 1/(time interval). The frequency of the moon's orbit around the earth is just over 12 cycles per year. His A string on the violin has a frequency of 440 vibrations or cycles per second.
