When a plane travels 395,000 meters in 9,000 seconds its speed is 395,000 ÷ 9000 = 43.888888 (the 8 repeats) meters per second.
Answer:
A
B
Explanation:
From the question we are told that
The wavelength is
The angle of first bright fringe is
The order of the fringe considered is n =1
Generally the condition for constructive interference is
=>
=>
Converting to cm
Generally the number of grating pre centimeter is mathematically represented as
=>
=>
Considering question B
From the question we are told that
The first wavelength is
The second wavelength is
The order of the fringe is
The grating is
Generally the slit width is mathematically represented as
=>
=>
Generally the condition for constructive interference for the first ray is mathematically represented as
=>
=>
=>
Generally the condition for constructive interference for the second ray is mathematically represented as
=>
=>
=>
Generally the angular separation is mathematically represented as
=>
=>
Answer:
Explanation:
Given
Distance to the planet = 35 light years. So, the entire distance is: 2 * 35 = 70.
i.e time of travel of the ship.
For the observer on earth, the time is:
The required speed so that it does not take more than 70 years is then calculated using:
Substitute
So, we have:
Make v the subject of formula.
Square both sides
Cross Multiply
Divide both sides by
Divide through by
Make the subject
Inverse both sides
Take square root of both sides
Substitute values for and
12.
The twelve cranial nerves are: olfactory nerve, optic nerve, oculomotor nerve, trochlear nerve, trigeminal nerve, abducens nerve, facial nerve, vestibulocochlear nerve, glossopharengeal nerve, vagus nerve, spinal accessory nerve, and hypoglossal nerve.

<span>The skier will transform their gravitational energy into mostly kinetic energy (with a minor amount transformed into heat from the friction of the skis across the snow and air friction). Once the skier hits the snowdrift, their kinetic energy is transferred into the snow which moves when they strike it due to the kinetic energy that is now in the snow. Along with again a minor amount of heat energy transferred as they move through the snowdrift.</span>
