Answer: Potential energy to kinetic energy

Explanation:

Potential energy is the form of energy possessed by a body due to its position.

Kinetic energy is the form of energy possessed by a body due to its motion.

When soldiers use their energy to hoist the trebuchet counterweight, the potential energy stored in the counter weight converts to kinetic energy of the counterweight as it is released and falls.

Calculate the force of gravity on the 0.50-kg mass if it were 6.4×106 m above earth's surface (that is, if it were two earth rad
Sunny_sXe [5.5K]

Radius of Earth is given as

R = 6.4 * 10^6 m

now here the height from the surface of earth is same as that of radius

h = 6.4 * 10^6 m

now here the acceleration due to gravity at this height is given as

g' = \frac{GM}{(R+h)^2}

g' = \frac{GM}{4R^2}

g' = \frac{g}{4}

now the force of gravity on the given object will be

F = mg'

F = m*\frac{g}{4}

F = 0.5 * \frac{9.8}{4}

F = 1.225 N

<em>so the force of gravity on it is 1.225 N</em>

Q1- the speed will increase because the particles will have more energy which causes them to move faster
trasher [3.6K]
<h3># Question </h3>

Q1- the speed will increase because the particles will have more energy which causes them to move faster

Explanation:

<h3>With an increase in temperature, the particles gain kinetic energy and move faster. The actual average speed of the particles depends on their mass as well as the temperature – heavier particles move more slowly than lighter ones at the same temperature. </h3>

What minimum speed must an electron have to excite the 492-nm-wavelength blue emission line in the hg spectrum?
mezya [45]
The energy required by the excitation of the line is:
ΔE = hν = hc / λ
where:
ΔE = energy difference
h = Planck constant 
ν = line frequency
c = speed of light
λ = line wavelength

The energy difference must be supplied by the electron, supposing it transfers all its kinetic energy to excite the line:
\Delta E =  \frac{1}{2} m v^{2}

Therefore, 
\frac{1}{2} m v^{2} =  \frac{hc}{\lambda}

And solving for v we get:
v =  \sqrt{ \frac{2hc}{m\lambda} }

Plugging in numbers (after trasforing into the correct SI units of measurement):
v = \sqrt{ \frac{(2)(6.6 \cdot  10^{-34})(3 \cdot  10^{8})  }{(9.11 \cdot  10^{-31})(4.92 \cdot  10^{-7}) } }
=9.4 · 10⁵ m/s

Hence, the electron must have a speed of 9.4 · 10<span>⁵ m/s in order to excite the <span>492nm</span> line.</span>
