Answer:
(B) perpendicular to and in the same direction as the transverse electric wave
Explanation:
They should make sure the area is dry
All transverse waves can be polarized. this is because these waves oscillate at 90 degrees to the direction of energy movement.

Answer:
32.176 ft/s²
9.807 m/s²
Explanation:
Data provided in the question:
Acceleration of the free falling object = 78979.4 mi/hr²
a) In ft/s
Now,
1 mi = 5280 foot
and,
1 hour = 3600 seconds
thus,
78979.4 mi/hr = 
or
78979.4 mi/hr = 32.176 ft/s² ...............(1)
b) In m/s²
Now,
1 foot = 0.3048 m
thus,
we have from 1
32.17 ft/s² = 
or
78979.4 mi/hr = 32.176 ft/s² = 9.807 m/s²
