Answer:
1) Buoyant force, 2) sinks, 3) equilibrium, 4) fleet , 5) LIFT force
Explanation:
A body in a fluid is subjected to two forces, its weight and the thrust
sun F = B - W
the em
bid is always vertical and contrary to weight, let's analyze and complete the different situations presented
1) Buoyant force
2) sinks B <W
3) equilibrium B = W
4) fleet B> W
5) by the sum of two forces:
* Thrust, but the density of air is much less than the density of water, therefore the thrust in the air is less.
* The other force in airplanes the lift force given by the difference in the path of the air when the plane moves, which translates into a pressure difference between the upper part of the wing and the lower part, it is force is called LIFT force
Answer:
Wavelength = 0.44 meter
Time period = 0.0013 seconds
Explanation:
Given:
Speed of sound = 330 m/s
Frequency = 750 Hz
Find:
Wavelength
Time period
Computation:
Wavelength = Velocity / Frequency
Wavelength = 330 / 750
Wavelength = 0.44 meter
Time period = 1 / Frequency
Time period = 1/750
Time period = 0.0013 seconds
Answer:
0.0972644
Explanation:
Wave length = wave speed / frequency
Wave length = 96 / 987
= 0.0972644
Bohrs atomic model only explains the atomic structure in which electrons travel around the nucleus in well-defined orbits determined by quantum conditions. A transition from a higher orbit to a lower orbit will release quantized energies of light, which would explain the light spectrum emitted by an element.
