The correct answer is B. Electrons emit and absorb energy based on their position around the nucleus.

Explanation:

In general, an atom's emission of photons (light) is the result of electrons, which are the negative charge particles that orbit the nucleus. Moreover, the emission of light is likely to occur if the electron is located at a specific energy level (position in the atom) and it moves to a lower level as this requires the loss of energy in the form of photons. Also, the electron can absorb the photons and as a result gain enough energy to move to a higher level. This implies the atom's emissions of light shows the relationship between electrons emitting and absorbing energy and their position or energy level.

A holiday ornament in the shape of a hollow sphere with mass M = 1.50×10−2 kg and radius R = 5.50×10−2 m is hung from a tree lim
pickupchik [31]

Answer:

T = 0.607 seconds

Explanation:

Given:

Mass, M = 1.50 × 10⁻² kg

Radius, R = 5.50 × 10⁻² m

Now,

the time period in terms of moment of inertia is given as:

T = 2\pi\sqrt\frac{I}{mgR}    .....................1

where, T is the time period

g is the acceleration due to gravity

I is the moment of inertia

Now,

Moment of inertia, I is given as:

I = \frac{5mR^{2}}{3}

on substituting the moment of inertia in the equation 1, we get

T = 2\pi\sqrt\frac{\frac{5mR^{2}}{3}}{mgR}

or

T = 2\pi\sqrt\frac{{5R}}{3g}

on substituting the valeus, we get

T = 2\pi\sqrt\frac{{5\times5.50\times10^{-2}}}{3\times9.8}

or

T = 0.607 seconds

Hence, the time period is 0.607 seconds

In a drag race, a car takes off from rest and covers 375 meters in 5 seconds. What is the
salantis [7]

Explanation:

s = ut + 1/2 a t^2

375 = 0 * 5 + 1/2 * a * (5)^2

375 = 1/2 * a * 25

a = 375*2/25

a = 15* 2

a = 30m/sec^2

v = u + at

v = 0 + 30 * 5

v = 150 m/sec

hope it helps you
