The data convincingly show that wave frequency does not affect wave speed. An increase in wave frequency caused a decrease in wavelength while the wave speed remained constant. The last three trials involved the same procedure with a different rope tension.
Answer: holding the ball in the air without moving it
Explanation:
When the ball goes up it’s potential energy
Answer:
56.7 m³
Explanation:
The radius of the circular area covered by the spill is 4.25 km
You can find the area covered by the spill by applying the formula for area of a circular surface
A=π×r² where π=3.14 and r=4.25km
A= 3.14×4.25² = 56.72 km²
Remember the total area is on average at 1 micron (1μm) thick.This is to say
1μm=1m³
So the minimum volume of oil covering the ocean surface in meters will be;
Change km² to m²
56.72 km²= 56.72×1000000=5.67×10⁷ m²
Finding the volume;
Volume = Area * thickness
Volume= 5.67×10⁷ m² * 1× 10⁻⁶ = 56.7 m³
Minimum amount of oil that was spilled is 56.7 m³
Answer:
A. Travel in one direction
Explanation:
light can be reflected and bent but light originally travels in one direction in straight lines
