Answer:
Explanation:
Wave produced in string and waves produced in air are different . The only similarity is that their frequency are equal . Otherwise , no similarity . One is transverse ( on wire ) , the other is longitudinal ( air ) . Their velocities too are different .
velocity = wavelength x frequency
if frequency is constant
wavelength ∝ velocity
wavelength is proportional to velocity . Since their velocities are different , their wavelength too will be different.
Hello!
Answer and explanation:
There are three main sources of heat in the deep earth:
1) heat from when the planet formed and accreted, which has not yet been lost.
2)frictional heating, caused by denser core material sinking to the center of the planet.
3) heat from the decay of radioactive elements.
Have a good day
Storing music digitally requires less storage room than analog records or tapes. Digital music is easier to copy and the copies are the same as the original. The quality of the signal does not degrade over long periods of time.
Explanation:
Forgive me If I am wrong, it's been a while since I've studied Torque.
The formula for the angular momentum is
momentum= I*w.
We can also write I*W as 1/2MR^2 * W so the extra mass coming from the block of clay would most likely cause the angular momentum to increase from the amount it was before.
Answer:
I = 11.26 mA
Explanation:
given,
V = 0.7 V length = 80 m
diameter = 0.2 mm = 0.02 cm
radius = 0.01 × 10⁻² m
ρ for gold wire = 2.44 × 10⁻⁸ ohm-m at 20 °C
A = cross sectional area = π r² = π (0.01 × 10⁻² )²
= 31.4× 10⁻⁹ m²
R = 62.165 Ω
I = 11.26 mA
