Answer:
velocity of this in the direction of the Earth is 6.4 × m/s
Explanation:
given data
wavelength = 121.6 nm
wavelength = 124.2 nm
solution
we get here first change in wavelength that is
= 124.2 nm - 121.6 nm ...............1
= 2.6 nm
we get here velocity of direction of the Earth that is express as
............2
put here value we get v
v =
v = 6.4 × m/s
Answer:
V = 15.6 m/s
Explanation:
using the equation of motion
v = u + at
v = 0 + 5.2(3)
v = 15.6 m/s
Answer:
150mm
Explanation:
The correct answer to the given question is 150mm or 6 inch.
Atleast 150mm or 6 inches of a free conductor, measured from the point in box where it emerges from its cable sheath or raceway, must be left at each outlet, switch or junction point to lumination or connection of devices.
150mm of free conductor is required for the devices to be connected, this needs to be placed in the junctions
Answer:
t = 25.5 min
Explanation:
To know how many minutes does Richard save, you first calculate the time that Richard takes with both velocities v1 = 65mph and v2 = 80mph.
Next, you calculate the difference between both times t1 and t2:
This is the time that Richard saves when he drives with a speed of 80mph. Finally, you convert the result to minutes:
hence, Richard saves 25.5 min (25 min and 30 s) when he drives with a speed of 80mph
