Acceleration=9.81m/s^2
initial velocity=0m/s
time=.28s
We have to find final velocity.
The equation we use is
Final velocity=initial velocity+acceleration x time
Vf=0m/s+(9.81m/s^2)(.28s)
Vf=2.7468m/s
We would round this to:
Vf (final velocity)=2.7m/s
Answer:
367.57 nm
Explanation:
Given that the speed of the light in certain material is 0.6310 times the speed of light in vacuum.
Speed of light in vacuum = 3×10⁸ m/s
Speed of the light in that material = 0.6310×3×10⁸ m/s = 1.893×10⁸ m/s
The frequency of the light does not change but the wavelength of the light changes with change in the speed when light travels from one medium to another.
Thus, frequency = 5.15×10¹⁴ Hz
Using,
c = frequency × Wavelength
Wavelength = c / frequency = (1.893×10⁸ m/s) / (5.15×10¹⁴ Hz) = 367.57×10⁻⁹ m
Also,
1 nm = 10⁻⁹ m
<u>So, wavelength = 367.57 nm</u>
Answer:
Yes, Venus does not have the same magnetic field as that of earth's
Explanation:
Instead, there are solar wind particles that can deeply penetrate the venus atmosphere and can collide with the other carbon atoms already present in the air but lacks oxygen and thus does not have that strong magnetic field which would deflect the suns rays and create aurora in the sky at night.
