<span>CH4 I assume you're doing a test or something but I'm not good at explaining things so hopefully it's multiple choice! </span>
Answer:
The orbital velocity
The period is
Explanation:
Generally centripetal force acting ring particle is equal to the gravitational force between the ring particle and the planet , this is mathematically represented as
=>
Here G is the gravitational constant with value
is the mass of with value
r is the is distance from the center of the to the outer edge of the A ring
i.e r = R + D
Here R is the radius of the planet with value
D is the distance from the equator to the outer edge of the A ring with value
So
=>

Answer: v = 2.24 m/s
Explanation: The <u>Law</u> <u>of</u> <u>Conservation</u> <u>of</u> <u>Energy</u> states that total energy is constant in any process and, it cannot be created nor destroyed, only transformed.
So, in the toy launcher, the energy of the compressed spring, called <u>Elastic</u> <u>Potential</u> <u>Energy (PE)</u>, transforms into the movement of the plastic sphere, called <u>Kinetic</u> <u>Energy (KE)</u>. Since total energy must be constant:
where the terms with subscript i are related to the initial of the process and the terms with subscript f relates to the final process.
The equation is calculated as:
v = 2.24
The maximum speed the plastic sphere will be launched is 2.24 m/s.
The characteristics of electromagnetic radiation include amplitude (brightness), wavelength, frequency, and period. We have shown that the frequency of a light wave is proportional to its energy by the equation E = h v or E=hnu
so
Radiation with a wavelength of 8.1 X 10^-8 m has the highest energy
<h3>Why is it called electromagnetic?</h3>
- When a charged particle, like an electron, changes its velocity—that is, when it is accelerated or decelerated—electromagnetic radiation is created. The charged particle is responsible for losing the energy of the electromagnetic radiation that is thus created.
- Since the electric and magnetic fields are oscillating, the waves of energy are known as electromagnetic (EM). They are categorized by scientists based on their frequency or wavelength, from high frequency to low frequency (short to long wavelength).

Answer:
The distance of the car from the mirror is 10 times the distance of the image of the car from the mirror
Explanation:
The parameters of the mirror image are;
The height of the car's image, h' = -14 cm (The image is inside the mirror and therefore, -ve)
The height of the car, h = 140 cm
The radius of curvature of the mirror, R = 60 cm
The mirror formula is given as follows;
Where;
u = The distance of the car from the mirror
v = The distance of the image of the car from the mirror
f = The focus of the mirror ≈ R2
The focus of convex mirrors is negative, therefore, f = -62 cm/2 = -32
Therefore, we get;
14·u = 140·v
∴ u = 140·v/14 = 10·v
The distance of the car from the mirror = 10 × The distance of the image of the car from the mirror
