Answer:

speed maximum

restoring force minimum

Explanation:

When the particle executing SHM is at its mean position or equilibrium position, then its velocity is maximum and the kinetic energy is also maximum. It is because the kinetic energy is proportional to the square of the velocity as velocity maximum then kinetic energy is also maximum.

The acceleration is minimum at the equilibrium position so the restoring force is also minimum t its equilibrium position.

Influenced by the gravitational pull of a distant star, the velocity of an asteroid changes from from +19.3 km/s to −18.8 km/s o
muminat

As per above given data

initial velocity = 19.3 km/s

final velocity = - 18.8 km/s

now in order to find the change in velocity

\Delta v = v_f - v_i

\Delta v = -18.8 - 19.3

\Delta v = -38.1 km/s

\Delta v = -3.81 * 10^4 m/s

Part b)

Now we need to find acceleration

acceleration is given by formula

a = \frac{\Delta v}{\Delta t}

given that

\Delta v =- 3.81 * 10^4 m/s

\Delta t = 2.07 years = 6.53 * 10^7 s

now the acceleration is given as

a = \frac{-3.81 * 10^4}{6.53 * 10^7}

a = - 5.84 * 10^{-4}m/s^2

so above is the acceleration

Sometimes a new experimental result may seem to go against a well-established scientific theory. Which statement BEST describes
MrMuchimi
The best thing to do in this case is to redo the experiment and re record the info, it has to be precise and accurate so you also have to check if your procedure is correct. If the results are both accurate and precise then you have to report your findings to the committee of that specific field. <span />

Green light can have a wavelength of 512 nm. The energy of a photon of this light is
Nat2105 [25]

Answer:

E = 3.88 * 10^{-17} J

Explanation:

Energy is directly proportional to frequency and it is given as:

E = hf

where h = Planck's constant

f = frequency

To get frequency, we use the formula of speed:

c = λf

where c = speed of light

λ = wavelength

=> f = c/λ

Therefore, the energy of the photon will be:

E = hc/λ

E = \frac{6.626 * 10^{-34} * 3 * 10^{8}  }{512 * 10^{-9} }

E = 3.88 * 10^{-17} J

The energy of the photon is 3.88 * 10^{-17} J
