What expression (formula) relates Kenetic energy of an object of mass to its momentum

Physics
1 answer:
zmey [24]3 years ago
3 0

Answer:

Correct answer:  Ek = I² / 2 · m

Explanation:

The formula by which kinetic energy is calculated is:

Ek = m V² / 2

The formula by which momentum i prefer the name impulse is calculated is:

I = m V

We will transform the formula for kinetic energy on the next way:

Ek = m V² / 2  we will multiply numerator and denominator with m and get:

Ek = m² V² / 2 m = (m v)² / 2 m = I² / 2 m

Ek = I² / 2 m

1) <span>A solar eclipse that occurs when the new moon is too far from earth to completely cover the sun can be either a partial solar eclipse or an -->
Answer: ANULAR ECLIPSE. Since the moon is too far, it will cover only a part of the sun, and only the external ring of the moon will be visible; this is called anular eclipse.

2) </span><span>anyone looking from the night side of earth can, in principle, see a -->
Answer: LUNAR ECLIPSE. If the moon is the right position, and the Earth's shadow covers partially or totally the moon, then a lunar eclipse occurs.

3) </span><span>during some lunar eclipses, the moon's appearance changes only slightly, because it passes only through the part of earth's shadow called the -->
Answer: PENUMBRA. 

4) </span><span>a ... can occur only when the moon is new and has an angular size larger than the sun in the sky -->
Answer: TOTAL SOLAR ECLIPSE. When the moon is new, it means it is between the sun and the Earth, and its dark side faces the Earth. If the moon's angular size is also larger than the sun angular size, than it will completely cover the sun, and a total solar eclipse occurs.

5) </span><span>a partial lunar eclipse begins when the moon first touches earth's --> 
Answer: SHADOW. The Earth's shadow will start to cover the moon, and partial lunar eclipse will start.

6) </span><span> a point at which the moon crosses earth's orbital plane is called a(n)  --> 
Answer: NODE. Eclipses occur only when the Moon is at or close to a node, otherwise sun, earth and moon are not "aligned".</span>

A flute plays a note with a frequency of 266 Hz. What is the speed of sound if the wavelength is 1.3 m?
hjlf

Wave speed  =  (frequency)  x  (wavelength)

                       =  (266 /sec)  x  (1.3 meters)

                       =     345.8 meters/sec

andrezito [222]

Answer:

F=7.7\times10^2 N

Explanation:

The magnitude of force required to pull the lid off the box by air pressure.

We know that Pressure, P= Force(F)/Area(A)

Force, F= P×A

Given: A=1.10\times10^{-2} m^2

P=7\times10^{4} Pa.

Therefore, F=7\times10^{4}\times1.10\times10^{-2}.

F=7.7\times10^2 N
