Time with program duration at a constant amount of acceleration: 1 to 4 seconds. In mechanics, acceleration is the price you pay for exchanging the speed of an object for time.

Acceleration is a vector quantity. The direction of acceleration of an object is given by the direction of the net force acting on it. Acceleration is the name we give to any method of adjusting speed. If you think of velocity as velocity and path, then there is the simplest way to acceleration: change alternate velocity or alternate path - or both.

Acceleration (a) is the exchange of the ratio (Δv) for the change in time (Δt) expressed by the equation a = Δv/Δt. There are three styles of ascent motion: uniform acceleration, non-uniform acceleration, and medium acceleration. . Uniform acceleration, non-uniform acceleration, and medium acceleration are three types of improved motion. Uniform time acceleration refers to the motion in which an object moves in a straight line, jumping with the speed at equal time intervals.

The acceleration due to gravity on astronaut on the alien planet will be 6.38 m/s²

Weight is a force exerted by earth on a body in a vertically downwards direction towards its center.

Mathematically -

Weight [W] = mass [m] x acceleration due to gravity [g].

Given is an astronaut whose weight is 655 N on Earth and the same astronaut weighs 465 N on an alien planet.

We can write -

Weight on earth [W] = 655 N

Acceleration due to gravity on Earth [g] = 9.8 m/s²

Weight on alien planet [W'] = 465 N

Assume the acceleration due to gravity on alien planet be g'.

Then -

W[earth] = mg = W.

W[alien planet] = mg' = W'.

Since the mass remains same, we can say that -

m[earth] = m[alien planet]

W/g = W'/g'

g' = (W'g)/W

g' = (465 x 9.8)/655

g' = 6.38 m/s²

Therefore, the acceleration due to gravity on astronaut on the alien planet will be 6.38 m/s²

The electron binding energy for gold essence is. find the longest wavelength( in) of light that could eject electrons from gold in a photoelectric effect trial.

Electron

The electron is a subatomic flyspeck( denoted by the symbol whose electric charge is negative one abecedariancharge.Electrons belong to the first generation of the lepton flyspeck family, and are generally allowed to be abecedarian patches because they've no given factors or substructure. The electron's mass is roughly 1/ 1836th that of the proton. Quantum mechanical parcels of the electron include an natural angular instigation( spin) of a half- integer value, expressed in units of the reduced Planck constant, ħ. Being fermions, no two electrons can enthrall the same amount state, in agreement with the Pauli rejection principle. Like all abecedarian patches, electrons parade parcels of both patches and swells They can collide with other patches and can be diffracted like light. The surge parcels of electrons are easier to observe with trials than those of other patches like neutrons and protons because electrons have a lower mass and hence a longer de Broglie wavelength for a given energy.

Electrons play an essential part in multitudinous physical marvels, similar as electricity, captivation, chemistry and thermal conductivity, and they also share in gravitational, electromagnetic and weak relations. Since an electron has charge, it has a girding electric field, and if that electron is moving relative to an bystander, said bystander will observe it to induce a glamorous field.

Answer:

look at the explanation

Explanation:

If this is the case, the pancake at the highest temperature will make the backside pancake the warmest due to transfer of thermal energy.

The switch of thermal strength between the hotter pancake and the backside pancake occurs through conduction. Conduction is a mode of transfer of thermal energy that takes place when the two bodies are in shut contact with each other.

After they have been touching for a while, the temperature of the backside pancake increases while the temperature of the top pancake decreases in view that thermal power is being transferred from the pinnacle pancake to the backside pancake.

Last option is correct that is the relationship between wavelength of light and the quantity of energy per photon is inversely related.

Energy is inversely correlated with wavelength because it is directly proportional to the electromagnetic frequency of the photon. The energy of a photon increases with its frequency. In other words, the energy of a photon decreases with increasing wavelength. Wavelength and frequency are related to energy in the same way that they are to light. Greater energy is correlated with shorter wavelengths and higher frequencies. Therefore, lower energy is produced by longer wavelengths and lower frequencies. E = hv is the energy equation. When we increase the denominator, the fraction also increases, resulting in a decrease in energy. As a result, energy and wavelength have an inverse relationship.

In order the weight feels tripled, the elevator should be moving upward with acceleration 2g m/s² or two times of gravitational acceleration.

The free body diagram is shown on the attached picture.

The scale will read the normal force.

Suppose the elevator is moving upward. Using the Newton's second law of motion:

∑F = m.a

N - w = ma

N = mg + ma

Suppose the elevator is moving downward.

w - N = ma

N = w - ma

N = mg - ma

Where:

m = mass

a = acceleration

g = gravitational acceleration

From the above 2 cases, in order the scale to read the measured weight higher than its actual weight, N should be greater than w, or N = mg + ma, or the elevator should be moving upward.

The weight feels tripled means N = 3 mg.

Hence,

3 mg = mg + ma

a = 3g - g = 2g

Therefore, in order the weight feels tripled, the elevator should be moving upward with acceleration 2g m/s²

a) Since the rope's breaking strength is 1,000 N Therefore therefore the stuntman cant make it without falling

b) The maximum speed (in m/s) that the stuntman can have at the bottom of the swing on this vine to safely swing across the river is 4.24m/s

To determine if the stuntman will make it across the pond without falling, we will solve for tension. Using the equation for Tension which is mathematically given as

T = mv²/r + (mg)

Where:

Mass of swing; m = 88.5

Speed or velocity of the stuntman; v = 8.30m/s

Length of rope; r = 11.5m

Gravity; g = 9.8

T =(88.5*8.30)²/11.5 + (88.5*9.8)

T = 6096.76 + 867.3

T = 5229.46N

Since the rope's breaking strength is 1,000 N Therefore he cant make it without falling

b. In finding the maximum speed that the stuntman can have at the bottom of the swing, We substitute into the equation for tension given as:

T = mv²/r + (mg)

1000 =(88.5*v²)/11.5 + (88.5*9.8)

A is the area of the loop.

As we can see, area is constant,

E = -AdM/dt

The value of M is 24sin(ωt).

So, putting the value of M,

E = -Ad(24sin(ωt))/dt

E = -A(24ωcos(ωt))

We know,

ω = 2πf

If you don't keep giving a car gas, the car will eventually stop because gas is a fuel that is used by the car as a form of energy.

Our car needs gas that allows the vehicle to operate and move in the forward direction. The fuel system does the process of combustion which moves the pistons of the engine and the car moves in the forward direction. Combustion occurs when the fuel in your engine is sparked by the spark plugs of the engine. When the spark combines with the gas fuel, the gas fuel blasts and moves the pistons which are attached to the tires of a car which leads to the movement of the car in the forward direction.

So we can conclude that the car will stop if the gas is not present in sufficient amounts because gas allows the car to move.
