Objects have the same velocity only if they are moving at the same speed and in the same direction. Objects moving at different speeds, in different directions, or both have different velocities.
Explanation:
Sound waves are often simplified to a description in terms of sinusoidal plane waves, which are characterized by these generic properties:
Frequency, or its inverse, wavelength.
Amplitude, sound pressure or Intensity.
Speed of sound.
Direction.
Answer:it has risen
Explanation:
It has risen due to the burning of fossil fuels which produces a lot of green house gases.and it has also risen due to deforestation,no enough plants to consume the green house gas(carbon dioxide)
Answer:
a = 16 m/s²
General Formulas and Concepts:
<u>Dynamics</u>
Newton's Law of Motions
- Newton's 1st Law of Motion: An object at rest remains at rest and an object in motion stays in motion
- Newton's 2nd Law of Motion: F = ma (Force is equal to [constant] mass times acceleration)
- Newton's 3rd Law of Motion: For every action, there is an equal and opposite reaction<u>
</u>
Explanation:
<u>Step 1: Define</u>
<em>Identify variables</em>
[Given] F = 22000 N
[Given] m = 1375 kg
[Solve] a
<u>Step 2: Find Acceleration</u>
- Substitute in variables [Newton's 2nd Law of Motion]: 22000 N = (1375 kg)a
- Isolate <em>a</em>: 16 m/s² = a
- Rewrite: a = 16 m/s²
