So far, I have not been able to run a mile in under 30 minutes.
That proves that I can't do it, but <span>that does not necessarily mean
its impossible. It </span>doesn't prove that nobody else can do it.
Nobody and nothing has ever traveled faster than the speed of light.
That doesn't prove that somebody or something that hasn't tried yet
can't do it. But discoveries in Physics, Quantum Mechanics, Cosmology,
and Relativity, over roughly the past 125 years, which explain and predict
almost everything seen in hundreds of experiments and thousands of
observations since then, do all agree that the speed of light is, let's say,
nature's "speed limit", and that no matter how hard you try, nothing and
nobody CAN travel faster.
The benefits of stretching the lower back on a regular basis include improving the range of motion,reducing back pain , and increasing the flexibility of tendons
Answer:The gravitational force is defined in Uniform Circular Motion and Gravitation, electric force in Electric Charge and Electric Field, magnetic force in Magnetism, and nuclear forces in Radioactivity and Nuclear Physics. On a macroscopic scale, electromagnetism and gravity are the basis for all forces.
Explanation:
The force exerted by the laser beam on a completely absorbing target is .
The given parameters;
- <em>power of the laser light, P = 1050 W</em>
- <em>wavelength of the emitted light, λ = 10 μm </em>
The speed of the emitted laser light is given as;
v = 3 x 10⁸ m/s
The force exerted by the laser beam on a completely absorbing target is calculated as follows;
P = Fv
Thus, the force exerted by the laser beam on a completely absorbing target is .
