Because there’s no elemental degradation, the mass of the compound EQUALS the sum of the masses.
Answer:
f = 4.76 × 10^14 Hz
Frequency of the laser light f = 4.76 × 10^14 Hz
Explanation:
Given;
wavelength = 6.33 x 10^-7 m
Speed of light v = 3.0 x 10^8 m/s.
Frequency of the laser light f
= speed of light/wavelength
Substituting the given values;
f = 3.0 x 10^8 m/s ÷ 6.33 x 10^-7 m
f = 4.76 × 10^14 Hz
Frequency of the laser light f = 4.76 × 10^14 Hz
Answer:
the Power required is 300 W
Explanation:
We know that the definition of work is given by the following expresion:
the distance is 1.5 meters and the Force is equal to 1000 N.
Replacing this values in the work expresion
And the power is equal to the amount of work done in a given time, therefore we have:
Time in seconds
Explanation:
Two objects that only have the force of gravity acting on them, will fall with the same acceleration <span>g=9.8<span>m<span>s2</span></span>; g=32.2<span><span>ft</span><span>s2</span></span></span> and will therefore hit the ground at the same time.
When you drop a feather, air resistance acts on all the surfaces of the feather. This causes the feather to slow down.
Air resistance depends on two factors: the speed of the object (increased for example by throwing it), and its surface area.
hope this can give u a little bet more to know about how to get ur answer :P
have a gud day and gud luck!
He has no acceleration because his velocity remains constant
