Answer:
2.56 m/s²
Explanation:
A standing wave is produced in the wire, its frequency f = n/2l√(T/μ). For the fundamental frequency, n = 1.
f = 1/2l√(T/μ)
where l = length of wire = 1.60 m, T₁ = tension in wire = weight of object = m₁g (neglecting wires mass), m₁ = mass of object = 3.00 kg, g = acceleration due to gravity on the small planet, μ = linear density of wire = m₀/l , m₀= mass of wire = 4.30 g = 0.0043 kg and f = 1/T where T = period of pulse = 59.9 ms = 0.0599 s
f = 1/2l√(T₀/μ) = 1/T ⇒ T₁ = 4l²μ/T²
m₁g = 4l²μ/T²
g = 4l²μ/m₁T² = 4l²m₀/l/m₁T² = 4lm₀/m₁T²
g = 4lm₀/m₁T² = 4 × 1.60 × 0.0043/(3.00 × 0.0599²) = 2.56 m/s²
Answer : The excess of electrons on the penny are, 
electrons
Solution : Given,
Total charge = 
Charge on electron = 
Formula used :
Now put all the given values in this formula, we get the excess of electrons present on the penny.
Therefore, the excess of electrons on the penny are, electrons

Answer:
The Average speed = 15000 / 0.005 = 3000000 m/s
Explanation:
- Average speed can be calculated by dividing the total distance covered by the total time.
Average speed = Total Distance / Total time
Given
- Total distance = 15km = 15(1000) = 15000 m
- Total time = 5 ms = 0.005 seconds
Thus,
Average speed = Total Distance / Total time
Average speed = 15000 / 0.005 = 3000000 m/s
Carbon 6 hydrogen 12 oxygen 6
Hope this helped!
You need to know the specific heat capacity of air.
Then energy needed = 0.005 x sp.heat.cap x 10
