Answer:
The temperature would be 194, 8 K.
Explanation:
We use the formula:
PV=nRT --> T=PV/nR
T= 0,500 atm x 28, 6 L/ 0,895 mol x 0,082 l atm /K mol
<em>T= 194,8494345 K</em>
We can assume that all<span> gravitational potential energy is converted into
kinetic energy of the object.</span><span>
<span>Hence, </span>GPE = KE
Where GPE is gravitational Potential Energy (J)
and KE is Kinetic Energy (J)
GPE = mgh
<span>Where, m is the mass of the object (kg), g is acceleration due to gravity (9.8 m s</span></span>⁻<span>²) and h is the height to the<span> object from ground (m).</span></span><span>
m = 0.18 kg
g = 9.8 m s</span>⁻²<span>
h = 45 m
Hence,
GPE = 0.18 kg x 9.8 m s</span>⁻² x 45 m<span>
= 79.38 J
≈ 79 J
<span>Hence, </span>KE = GPE = 79 J
<span>Hence, the
answer is '79 joules'.</span></span>
Answer:
The process of breaking down stones or rocks into small pieces is called weathering.
Explanation:
Silicon has 14 protons and it should have at least 12 neutrons
