If the electron just misses the upper plate as it emerges from the field, find the speed of the electron as it emerges from the field?.

The formula that we will apply to get to the answer would be:

2as = v² - u²

Using this we will get the answer as 82.35425 m.

Here,

U= initial velocity

V= final velocity

S= displacement of the body

A= acceleration of the body/ acceleration due to gravity (as per the question)

Something that has not been mentioned here but is present in the original question is that the acceleration due to gravity has been given as 0.170g.

While throwing the wrench on earth,

v² - u² = 2as

⇒[tex]u = \sqrt{v^2 - 2as}[/tex]

⇒ u = [tex]\sqrt{0-2 * -9.81 * 14}[/tex]

⇒ u= 16.57347 m/s

Since the astronaut gives the same starting speed in both the places so the u on moon would be 16.57347 m/s

While throwing the wrench on moon,

v² - u² = 2as

s = [tex]\frac{v^2 - u^2}{2a}[/tex]

⇒ s =  [tex]\frac{0^2 - 16.57347^2}{2 * (-9.81) * 0.17}[/tex]

⇒s = 82.35425 m

so, on moon, the wrench could be thrown a distance of 82.35425 m

By using uniform motion, the speed before hitting the ground is 23.00 m/s.

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 = 0 m/s

t = 1.45 s

y = 27 m

g = 9.8 m/s²

By using the second equation, we can calculate the speed before hit the ground.

vt² = vo² + 2a . s

vt² = 0² + 2g . 27

vt² = 2 . 9.8 . 27

vt² = 529.2

vt = 23.00 m/s

A sine wave has a rms value of 208 v, the peak value is 294.15v.

The RMS value of a set of values (or a continuous-time waveform) is the square root of the arithmetic mean of the squares of the values, or square of the function that defines the continuous waveform. In physics, RMS current value can also be defined as the "value of the direct current that dissipates same power in a resistor".

Physical scientists often use the term root mean square as a synonym for standard deviation when it can be assumed input signal has zero mean, that is, referring to the square root of mean squared deviation of a signal from a given baseline or fit. This is useful for the electrical engineers in calculating "AC only" RMS of a signal. Standard deviation being the RMS of a signal's variation about the mean, rather than about 0, DC component is removed (that is, RMS(signal) = std e v (signal) if the mean signal is 0).

Mean power, or root mean square (RMS) power handling, refers to how much continuous power speaker can handle. The peak power handling value refers to the maximum power level that speaker is capable of utilizing in short bursts.

We need to know about vectors to solve this problem. Vector has magnitude and also direction. Displacement is included in vector. It can be written as

s = sx i + sy j + sz k

where s is displacement, sx is displacement on x-axis, sy is displacement on y-axis and sz us displacement on z-axis.

From the question above, we know that

Kinematics is the study of mechanical points, bodies, and systems in motion without taking into account the forces acting on them or the corresponding physical qualities.

Kinematics equations of motion define the fundamentals of an object's motion, such as its position, velocity, or acceleration over time. These three equations of motion control how an item moves in one, two, and three dimensions.

Kinetics considers physical forces as well as material characteristics such as mass stiffness and tensile or compressive strength. These characteristics can be used to take a theoretical model from kinematics and use physics and thermodynamics to determine how to construct a workable, dependable, and functional real-world system.

Given,

Initial velocity, u = 4m/s

Acceleration, a = 2m/s-2

Displacement, s= 45m

we know that,

Here it is seen that mvy is a constant, therefore the angular momentum is constant.

The rotational equivalent of linear momentum in physics is called angular momentum, also known as moment of momentum or rotational momentum.

Because it is a conserved quantity, while calculating the total angular momentum of a closed system, it stays constant—it is significant in physics.

The direction and the amplitude of angular momentum are all conserved. The functional characteristics of bicycles and motorbikes, frisbees, rifled bullets, and gyroscopes are due to the conservation of angular momentum.

Before Galileo, Aristotle’s writings had been accepted as true for over a thousand years. He claimed that heavier objects fall faster than lighter ones and that an object that weighs twice as much as another will fall twice as fast.

In his book Two New Sciences, Galileo outlined his theories regarding falling objects and projectiles in general (1638).
