What is the acceleration of a 50 kg object pushed with a force of 500 newtons? known? unknown? calculation? answer? units? equation?

The accelerating potential needed to produce electrons of wavelength 6.00 nm is 0.0415 volts.

Using the de Broglie wavelength formula, we can find the momentum of the electron and then the accelerating potential. as,

λ = h/p

∴ p = h/λ = 6.6 × 10⁻³⁴/6 × 10⁻⁹ = 1.1 × 10⁻²⁵ Kg m/s.

The momentum of an electron can be expressed in terms of its kinetic energy (K) as:

\(p=\sqrt{2mK}\) (where m is the mass of the electron)

And we know, the kinetic energy of the electron as,

K = eV (where e is the elementary charge)

∴ \(p=\sqrt{2meV}\)

∴ \(V=\frac{p^{2} }{2me}\)

Now, substituting the values of momentum, mass and charge;

we get:

V = (1.1 × 10⁻²⁵)² / (2 * 9.1 x 10⁻³¹ kg * 1.6 x 10⁻¹⁹ C)

= 0.0415 V

Therefore, the accelerating potential needed to produce electrons of wavelength 6.00 nm is 0.0415 V (or, 41.5 mV).

Answer:

The drawdown in a confined aquifer under transient conditions can be estimated using the Theis solution for the non-equilibrium radial flow of water. This solution is given by:

s = Q / (4πT) * W(u),

where s is the drawdown, Q is the pumping rate, T is the transmissivity, and W(u) is the well function (also called the Theis function) which depends on the variable u, where:

u = r²S / (4Tt),

where r is the distance from the pumping well and t is the time since pumping began.

Given T = 2500 m²/day, S = 1.0 x 10-3, and Q = 500 m³/day, we can calculate the drawdown at 10 m (r1 = 10 m) and 50 m (r2 = 50 m) for t = 150 days.

For (i) r1 = 10 m:

u1 = r1²S / (4Tt) = (10 m)² * 1.0 x 10-3 / (4 * 2500 m²/day * 150 days) = 0.000667

s1 = Q / (4πT) * W(u1) = 500 m³/day / (4π * 2500 m²/day) * W(0.000667).

For (ii) r2 = 50 m:

u2 = r2²S / (4Tt) = (50 m)² * 1.0 x 10-3 / (4 * 2500 m²/day * 150 days) = 0.01667

s2 = Q / (4πT) * W(u2) = 500 m³/day / (4π * 2500 m²/day) * W(0.01667).

Explanation:

Unfortunately, the well function W(u) cannot be evaluated directly without more specialized knowledge or tools. The well function is related to the exponential integral function, which requires numerical computation. You would typically use a table of values, a calculator with this function, or a computer program to evaluate it. After obtaining W(u), multiply it by the remaining fraction to find the drawdowns.

The velocity of a small ladybug that's sitting on the edge of a rotating disk (like an old vinyl album) increases as the lady bug walks along a circular path at a constant radius.

Explanation: The acceleration experienced by the ladybug is due to centripetal acceleration, which is always perpendicular to the ladybug's velocity. Because acceleration is a vector quantity, the centripetal acceleration vector constantly changes direction as it points toward the rotation axis. To comprehend why the ladybug's velocity varies as it moves around the disc, consider two distinct locations on the ladybug's path. The first location is at the top of the circle, and the second location is halfway down the circle. Because of the centripetal acceleration, the ladybug moves in a circle. As a result, it must have a net force toward the centre of the circle. The ladybug's direction of motion is perpendicular to the force acting on it. So, the ladybug accelerates toward the centre of the circle, and its speed varies. The ladybug is initially stationary when it begins its journey around the circle. When it moves along the circle path at a constant radius, its velocity grows due to centripetal acceleration. It is said that the velocity of the ladybug increases as it travels along a circular path with a constant radius. So, the correct answer is option b.

Answer:

c. hot material must be rising from the Sun's hotter interior

Explanation:

Granulation is the grainy appearance of the solar photosphere produced by the top of the convection cells in the sun.

The grainy appearance are produced by granules on the photosphere of the sun and granules are caused by convection currents of plasma within the sun's convection zone.

The interior of these granules are brighter (and thus hotter) than the exterior of the granules which are darker.

So, the granulation pattern that astronomers have observed on the surface of the Sun tells us that hot material must be rising from the Sun's hotter interior.

At equilibrium, the forces exerted by the front and back hooves must be equal, but the force exerted by the front hooves will be slightly greater than that of the back hooves.

What is equilibrium?
Chemical equilibrium refers to the situation inside a chemical reaction where both the reactants are present at levels that have no further habit of changing over time, preventing any discernible change in the system's properties. Whenever the forward reaction and the reverse reaction move forward at the same speed, this condition results. The forward as well as backward reactions typically have equal, if not zero, reaction rates. The concentrations of a products and reactants do not change on a net basis as a result. Dynamic equilibrium is the name given to such a situation.

This is due to the fact that the horse's center of gravity is closer to the front hooves, and thus the front hooves must exert a greater force in order to keep the horse balanced.

The average power delivered to the train during its acceleration is 0.3 W

Initial velocity (u) = 0 m/s

Final velocity (v) = 0.620 m/s

Time interval  (Δt)= 21.0 milisecond

Mass of train (m) = 875g

Power is defined as the work done for a specific time period or it is also the rate of doing work.

so we can also write power as :

Power (P)  = work done (W)/ time interval  (Δt)

Work done is defined as the dot product of the force acted on an object and the distance travelled by the object on the application of that force.

Work done (W) = force(f) × distance (s)

F = m × a      (from the newton’s second law of motion)

We have learnt from the 2nd equation of motion that :

a = (v-u)/t

distance (s) = average velocity / time

                     = (0.620 ×1000 )/ (2 × 21 )

                     =14.76 m

Substituting the value of force into the expression of work

P =( m × a × s )/ t

  = (875 × 620 × 14.76 )/(1000 × 1000 × 21)

Power is defined as the product of current and potential differences in a circuit. Current is defined as the flow of charges when the circuit is connected to the battery. The power in the circuit is Watt (W).

From the given,

potential difference(V) = 220V

Power (P) = 100 W

Current (I)=?

It has a longer wavelength and lower frequency than visible light, and it is part of the electromagnetic spectrum that also includes radio waves, microwaves, visible light, ultraviolet radiation, X-rays, and gamma rays.

Infrared radiation is often associated with thermal radiation, which is the emission of electromagnetic waves from objects that are at a temperature above absolute zero. This is because infrared radiation is often emitted by objects that are warm, and it is this type of infrared radiation that is responsible for our ability to feel heat.

Infrared radiation has a wide range of applications, including in remote sensing, thermal imaging, and heating. For example, in remote sensing, infrared radiation can be used to observe and study the Earth and other celestial objects, as well as to detect and monitor changes in temperature, vegetation, and other physical properties. In thermal imaging, infrared cameras are used to detect heat signatures and create images based on temperature differences.
