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:
L= 1.468 m
Explanation:
The moment of inertia of the rod about its center is (1/12)m_RL^2
The moment of inertia of each of the two bodies about the described axes is m_B(L/2)2
Hence, the moment of inertia of three body system is (1/12)m_RL^2+ 2×m_B(L/2)^2 which is given to be equal to I_T
=> L^2[(1/12)m_R+m_B/2] = I_T
=> L2 = IT/(mR/12+ mB/2)
=> L = sqrt( 12I_T/(m_R+6m_B))
now putting the value of m_R= 3.47 kg
m_B= 0.263 kg
I_T = 0.97 kg/m^2
L= 1.468 m is the length of the rod be so that the moment of inertia of the three-body system
Answer:
Developmental psychologists
Explanation:
Developmental psychology is defined as the scientific study that why and how a person change over their entire lifespan. It explains that how the thinking, behavior and feeling of a person changes throughout their life.
Parent have great influence on their child's mindset and there are several instances where parent's thinking determine what their child become in near future. For example, during toddler-hood babies learn to walk and talk and with time development of language take place which is largely determined by the behavior, thinking and feeling of parent.
Answer:
In mechanics, acceleration is the rate of change of the velocity of an object with respect to time.
Explanation:
Answer:
11.25m
Explanation:
vf^2=vi^2+2ad
0^2=15^2+2×(-10)d
0=225+-20d(remove 225 by doing the opposite operation)
-225÷-20=-20d÷-20(remove -20 by dividing by itself)
11.25= d (the answer becomes this)
