<h2>Answer:</h2>

<u>A) objects that shine  </u>

<u>B) hot objects  </u>

<h2>Explanation:</h2>

Actually our eyes see objects when light reflects from those objects and reach our eyes. Emission of light is only possible from source of light. The other one is reflection. So in the given options shiny objects and hot objects can become the source of light that is why we can say that shiny and hot objects emit light.

How would i solve for force when there are multiple accelerations?
damaskus [11]

"Multiple accelerations" is a puzzling phrase, and I'd be curious to understand it
better.  Sadly however, you haven't explained it at all.

If the multiple accelerations are the accelerations of multiple objects, then
the net force on each object is the product of (its mass) x (its acceleration).

If the multiple accelerations are the acceleration of one object at different times,
then at any instant of time, the net force on the object is the product of (its mass) x
(its acceleration at that instant).

Tsunamis are fast-moving waves often generated by underwater earthquakes. In the deep ocean their amplitude is barely noticable,
Charra [1.4K]

To develop this problem it is necessary to apply the concepts related to the kinematic equations of motion. And from the speed found the relationships between wavelength, frequency and last of the period (which is inversely proportional to the frequency)

PART A) We know that the velocity of a body or a wave is equivalent to the distance traveled over a time interval. So,

V = \frac{x}{t}

Where

x = Distance

t = time

V = \frac{3650*10^{3}}{4.59h(\frac{3600s}{1h})}

V = 215.44m/s

PART B) The frequency would then be defined as

f = \frac{V}{\lambda}

Where

\lambda = Wavelength

f = \frac{215.44}{732*10^{3}}

f = 2.943*10^{-4}Hz

PART C) Finally the period is defined as

T = \frac{1}{f}

T = \frac{1}{2.943*10^{-4}}

T = \frac{1}{2.943*10^{-4}}

T = 3397.89s

How does height affects the potential energy of a body?<br>​
ivann1987 [24]

Answer:

The higher the height above the more PE (Potential Energy), the body posses as seen in the formula PE = mass*gravity*height. m and g are constant hence only h affect PE

Explanation:

Potential Energy (PE) is the energy the body posses by virtue of its vertical height above the ground because, once the body is released, it will release or create some energy eg hydroelectricity power generation or a car going downhill does not need to be accelerated by the driver since it can roll over on its own due to PE
