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
You just told us that Weight = (mass) x (gravity),
and that mass=10kg and gravity = 9.8 m/s².
All we need to do is write those numbers in place of the letters.
Weight = (10 kg) x (9.8 m/s²) = <em>98 newtons</em>.
Explanation:
A worker picks up the bag of gravel. We need to find the speed of the bucket after it has descended 2.30 m from rest. It is case of conservation of energy. So,
h = 2.3 m
So, the speed of the bucket after it has descended 2.30 m from rest is 6.71 m/s.
Answer:
Acceleration
Explanation:
Acceleration has units of length per time squared.
