Answer:
Waves have many properties, including frequency, wavelength, amplitude, timbre, and direction. ... A higher frequency sound is perceived as a higher note, because frequency is the same thing as pitch. The amplitude is how tall the wave is. A higher amplitude sound wave is a louder sound.
Explanation:
Answer:
1. Velocity match with B
2. Speed watch with E
3. Gravity match with C
4. Deceleration match with A
5. Newton match with D
Explanation:
1.)
Velocity is defined as the time rate of change of displacement. It is a vector quantity. So it has certain direction as mention in option B. So B is the correct matching.
v = Δd/Δt
2.)
Speed is defined as the time rate of change of distance. It is a scalar quantity. It is same as velocity but only difference is that velocity has magnitude as well as direction but speed has only magnitude. As in option E, direction not mentioned. So E is the correct matching.
3.)
Gravity is the force of attraction between any two objects, two masses. It is not only the force between body and the Earth but it is the force that exist between any two bodies in the universe. C is the correct matching.
4.)
Deceleration is actually the acceleration but in the opposite direction. It is also called negative acceleration. When the velocity of the object increasing it is acceleration and when velocity decreasing it is called deceleration. It is always opposite direction to velocity. So A is the correct matching.
5.)
Newton is the name of the scientist. Also it is the unit of force in metric system. Here newton means unit of force because n of newton in small letter. From Newton's second law of motion
F = ma
= (kg)(m/s²)
= N
Thus,
N = kgms⁻²
Option D is correct matching.
Force that acts on area is defined as pressure,
If we solve for area,
Now put in the data.
The area of surface is 0.01m^2
Hope this helps.

Voltage is additive in series. The voltage drop across each load is added to equal the total voltage.
