a uniform electric field exists in the region between two oppositely charged plane parallel plates. a proton is released from rest at the surface of the positively charged plate and strikes the surface of the opposite plate, 1.60 cmcm distant from the first, in a time interval of 3.80×10−6 ss .

The gas must be heated to 137˚C to occupy a volume of 557 ml.

The gas pressure will remain constant while the piston is free to move. So, we can resolve this using Charles' Law.

Charles' law states that, if the pressure is constant, the volume occupied by a fixed quantity of gas is precisely proportional to its absolute temperature.

The ideal gas rule has an exception known as Charle's law.

The law is applicable to ideal gases with constant pressure but varying temperatures and volumes.

The equation of Charles' law is PV = k where k may is constant.

When measurements are taken under constant pressure, Charles' law establishes a relationship between a gas's volume and temperature.

The volume of the balloon  will be 0.056 m³ when it just begins to rise in the air.

A measurement of three-dimensional space is volume. Numerous imperial or US customary units, as well as SI-derived units (such the cubic metre and litre), are frequently used to quantify it numerically (such as the gallon, quart, cubic inch).

The definition of length (cubed) and volume are connected. The volume of a container is typically thought of as its capacity, or the amount of fluid (gas or liquid) that it could hold, as opposed to the amount of space the container occupies.

Mass of the balloon is = 0.030 kg.

Density of the gas inside the balloon is = 0.54 kg/m³

density of air outside the balloon is 1.29 kg/m³

The speed of his take off is 43.2 m/s if he left the take-off ramp at 120° to the horizontal and that the take-off and landing heights are the same. neglecting air drag.

Velocity is the directional speed of a moving item as an indication of its rate of change in position as seen from a specific frame of reference and measured by a specific time standard (e.g., 60 km/h northbound). The idea of velocity is crucial in kinematics, the part of classical mechanics that explains the motion of bodies.

A physical vector quantity called velocity requires both magnitude and direction to be defined. Speed is a coherent derived unit that expresses the scalar absolute value (magnitude) of velocity. Its quantity is expressed in SI (metric system) units of metres per second (m/s or ms1). For example, "5 meters per second" is a scalar while "5 meters per second east" is a vector.

Explanation:

The average acceleration of the baseball while it is compressing the glove is 1008 10⁻³ m / s². The kinematic formula used is v² = v₀² - 2 a x.

Acceleration is the rate of change in a moving object's speed and direction over time. When a point or object accelerates or decelerates, it is moving straight forward. Motion on a circle increases despite the same speed because the direction is always changing.

Because the acceleration occurs in the opposite direction as the speed and the end speed is zero, the sign is negative.

0 = v₀² - 2 an x

a = v₀² / 2x

Consider converting the magnitudes to the SI system.

x = 2.4 mm (1 meter / 103 mm) = 2.4 103 m

λ=h/Mv

where 'λ' is de Broglie wavelength, 'h' is Planck's constant having its value as 6.626×10⁻³⁴ kg-m²/s and 'M' is the mass of the particle.

Psychology researchers are using deductive reasoning.

In psychological researches, reasoning is important to reach conclusions. Two important types of reasoning used by researchers are: Inductive reasoning and deductive reasoning.

In deductive reasoning, psychological research starts with a hypothesis formed from a general theory and then try to establish it true in real cases. They start from predicted conclusions or assumptions first and then gather data through careful observations to support the hypothesis. After analyzing the data thus collected, they will prove their assumptions true in specific cases of the theory. So deductive reasoning is used to prove general ideas in empirical observations.

However, inductive reasoning is opposite to this approach. It incorporates the method of reaching conclusions by beginning with observed data to make new theories.

The speed of the runner at the end of the 2 seconds is 2·A

Calculation

The given information are;

The distance the sprinter is running = 100 m

The initial constant acceleration of the sprinter, a = A

The duration of the initial acceleration, t = 2 s

The initial speed of the printer, u = 0 (The sprinter starts from rest)

The rate with which the sprinter then runs with to the end = Constant speed

Therefor, we have, from the equation of motion;

s = u × t + 1/2 × a × t²

Where;

s = The distance ran by the sprinter

∴ at t = 2 seconds, we have;

s = 0 × 2 + 1/2 × A × 2² = 1/2 × A × 4 = 2·A

The distance ran by the runner in the 2 seconds = 2·A

The speed, v, of the runner at the end of the 2 seconds is given as follows;

A change in temperature frequently causes substances to change phases. Most substances are solid at low temperatures; as the temperature rises, they become liquid; and at still greater temperatures, they become gaseous.

Melting is the conversion of a solid into a liquid (an older term that you may see sometimes is fusion). Solidification is the process where a liquid turns into a solid. The melting point, or the temperature at which a pure substance begins to melt, is a property of that substance. A solid must expend energy to become a liquid. A specific quantity of energy is required by every pure substance in order to transform from a solid to a liquid. This amount is known as the substance's enthalpy of fusion (or heat of fusion).

By using uniform motion, the location of the airplane when the rock hits the ground is ( 550 . √(2h/g) + h )miles.

We need to know about the uniform motion to solve this problem. The uniform motion is an object's motion under acceleration. It should follow the rule

vt = vo + a . t

vt² = vo² + 2a . s

s = vo . t + 1/2 . a . t²

where vt is final velocity, vo is initial velocity, a is acceleration, t is time and s is displacement.

From the question above, we know that

vo = 550 mile/h

Find the time taken to hit the ground

s = vo . t + 1/2 . a . t²

h = 0 . t + 1/2 . g . t²

t² = 2h/g

t = √(2h/g)

Find the distance traveled by plane

To solve this exercise the formula for uniformly varied rectilinear motion (UVRM) and free fall to be applied are:

Where:

Information about the problem:

Applying the formula for UVRM we can calculate the height of the hot air balloon:

h = vi * t + (a * t²) / 2

h = 0 m/s * 8 s + [1.25 m/s² * (8 s)²] / 2

h = 0 m + [1.25 m/s² * 64 s²] / 2

h = 0 m + 80 m / 2

h = 80 m/ 2

h = 40 m

Knowing height of the hot air balloon and applying the time formula we can calculate the time taken for the stone to hit the ground:

t = √[ (2*h) / g]

t = √[ (2* 40 m) / 9.8 m/s²]

t = √[ 80 m / 9.8 m/s²]
