Answer:
λ = 3.1824 10-25 m
Explanation:
To release the electron from the power well the absorbed photon electro must be greater than or equal to the energy of the electron in the power well
The photon energy is E_photon = 0.625 J
The speed of light is
c = λ f
Let's use Planck's equation
E = h f
We substitute
E = h c / λ
λ = h c / E
λ = 6.63 10-34 3 108 / 0.625
λ = 3.1824 10-25 m
1 newton is the force that accelerates
1 kilogram of mass at the rate of 1 m/s² .
So in SI base units, 1 newton = 1 kg-m/s² .
and 3 kg-m/s² = 3 newtons .
Answer: B
Explanation:
You can use the conservation of momentum, under the assumption that no mass was lost when the collision occurred. The initial momentum of the system must equal the final momentum of the system. Our system is the region including, and only including, the satellite and the space debris. Classical momentum is defined as the product of mass and velocity:


Due to mass 1 equaling mass 2, we can factor these quantities out:

Cancel the mass term on both sides to get:

We have the initial and final velocities for everything besides the final velocity of the satellite. Plug everything in:


Answer:
a

b

Explanation:
From the question we are told that
The spring constant is 
The maximum extension of the spring is 
The number of oscillation is 
The time taken is 
Generally the the angular speed of this oscillations is mathematically represented as

where T is the period which is mathematically represented as

substituting values


Thus


this angular speed can also be represented mathematically as

=> 
substituting values


In SHM (simple harmonic motion )the equation for velocity is mathematically represented as

The velocity is maximum when

=> 
=> 
=> 
The magnitude is 13.12 mV.
The steps are attached below.
<h3>How do you find the magnitude of an induced emf?</h3>
The standard SI unit of the magnetic field is the tesla (T). As an end result, we can use these equations and the equation for an induced emf due to changes in magnetic flux, ϵ=−NΔϕΔt ϵ = − N Δ ϕ Δ t, to calculate the importance of a precipitated emf in a solenoid.
The magnitude of the precipitated contemporary depends on the rate of trade of magnetic flux or the fee of reducing the magnetic area strains.
