Answer:
c. Throw the items away from the spaceship.
Explanation:
By the Principle of action and reaction yu can get back to your spacecraft throwing the items away from the spaceship.
Answer:
Δλ = 3*10⁻³ m.
Explanation:
- At any wave, there exists a fixed relationship between the speed of the wave, the wavelength, and the frequency, as follows:

where v is the speed, λ is the wavelength and f is the frequency.
- Rearranging terms, we can get λ from the other two parameters, as follows:

- Since v is constant for sound at 343 m/s, we can find the different wavelengths at different frequencies, as follows:


- The difference between both wavelengths, is just the difference between (3) and (4):

⇒ Δλ = 3*10⁻³ m.
Answer:
v = 10 V and E = 2 10³ N/C
Explanation:
The electrical potentials and the electric field at one point are related by the expression
ΔV = - ∫ E. dS
Where the bold indicates vector quantities, E is the electric field and S is the line of displacement of the load, in general displacement is perpendicular to the equipotential lines, which reduces the product scales to the ordinary product.
If the potential difference is the most usual that is V = 10 V, the electric field is
s = 0.5 cm = 0.5 10⁻² m
E = ΔV / S
E = 10/0.5 10⁻²
E = 2 10³ N / C
they act as sunshades from the sun intensity, and filters
