Answer and Explanation:
with reference to Einstein's theory of special relativity, the speed of an electromagnetic radiation, here, laser will not change in any inertial frame or remains same irrespective of any change in inertial frame.
Therefore, the speed of light measured in both the cases, i.e., in astronaut's reference frame and spaceship's reference frame will be equal to the speed of light in vacuum, i.e., .
The laser gun's speed in astronaut's reference frame is the same as the speed of the spaceship as it mounted on it, i.e., the speed of the laser gun is 200 million m/s.
The laser gun's speed measured in spaceship's reference frame will be zero, as it is mounted on the spaceship and is stationary in the spaceship's reference frame.
Answer:
<em>The basketball player jumped 10 m high.</em>
Explanation:
<u>Vertical Launch Upwards </u>
In a vertical launch upwards, an object is launched vertically up without taking into consideration any kind of friction with the air.
If vo is the initial speed and g is the acceleration of gravity, the maximum height reached by the object is given by:
The basketball player jumps up with a speed of vo=14 m/s. The maximum height is:
The basketball player jumped 10 m high.
Answer:
313 K or 40 degree celsius.
Explanation:
Initial
,
Now, final
Combined the ideal gas law
Therefore, the final temperature of ideal gas is 313 K.
Answer:
0.003181 radians
0.003005 radians
Explanation:
Number of slits = 140 /cm
λ = Wavelength = 434 nm = 434×10⁻⁹ m
m = 3 Third order spectrum
Space between slits
Now,
0.003181 radians
When λ = 410 nm = 410×10⁻⁹ m
0.003005 radians
Explanation:
Formula for steady flow energy equation for the flow of fluid is as follows.
Now, we will substitute 0 for both and
, 0 for w, 334.9 kJ/kg for
, 2726.5 kJ/kg for
, 5 m/s for
and 220 m/s for
.
Putting the given values into the above formula as follows.
q = 6597.711 kJ
Thus, we can conclude that heat transferred through the coil per unit mass of water is 6597.711 kJ.
