Answer:
The answer to your question is: 10.48 km/s
Explanation:
Data
h = 5.6 x 10⁶ m
g = 9.8 m/s²
Formula
vf = 
Substitution
vf = 
vf = 
vf = 10476.64 m/s
convert to km/s
vf = 10476.64/1000
vf = 10.48 km/s
Answer:
Explanation:
Let the charge on proton be q .
energy gain by proton in a field having potential difference of V₀
= V₀ q
Due to gain of energy , its kinetic energy becomes 1/2 m v₀²
where m is mass and v₀ is velocity of proton
V₀ q = 1/2 m v₀²
In the second case , gain of energy in electrical field
= 2 V₀q , if v be the velocity gained in the second case
2 V₀q = 1/2 m v²
1/2 m v² = 2 V₀q = 2 x 1/2 m v₀²
mv² = 2 m v₀²
v = √2 v₀
Answer:
the answer is A.
Explanation:
An atom contains equal numbers of protons and electrons . Since protons and electrons have equal and opposite charges , this means that atoms are neutral overall.
