Answer:
Remains constant
Explanation:
As the wave travels from A to B in the pool, their frequency remains constant and so their wavelength.
A wave is a disturbance that transmits energy from one point to another. The frequency of a wave is the number of waves that crosses a point per unit of time. Wavelength is the differences between successive troughs or crests in a wave diagram.
- Both frequency and wavelength are related.
- If the frequency of a wave is kept constant, the wavelength will also not change.
- Frequency is inversely proportional to wavelength.
- The higher the frequency of a wave, the lesser its wavelength and vice versa.
Answer:
Explanation:
When the apples fall from a tree, it is known that gravity acts on the apple.
Since the apple fall in the direction of gravity downward, then a positive work is done on the apple
The potential energy reduces because the height reduces(mgh) and as the height reduces the potential energy reduces.
The potential energy is maximum at the top while kinetic energy is maximum at the ground.
The sum of the PE and KE is constant, so PE is maximum at top and it keep decreases till when KE is maximum
The first option is the correct option.
<span>Water molecules hydrogen bond with neighboring water molecules. Hydrogen bonding is very strong. The partial positive of the oxygen attracts the partial positive of the hydrogen so they bind to each other.</span>
Electron volts...........
Answer:
826.36203 m/s²
Explanation:
= Final angular velocity = 470.2 rad/s
= Final angular velocity = 0
= Angular acceleration
t = Time taken
Equation of rotational motion
Magnitude of the average angular acceleration of the disk is 826.36203 m/s²
