Answer:
The second box
Explanation:
Work done is the force applied to move a body through a particular distance.
Work done = Force x distance
For the first box:
Weight = 12N
Distance = 1m
Work done = 12 x 1 = 12J
For the second box;
Weight = 1000N
Distance = 30cm = 0.3m
Work done = 1000 x 0.3 = 300J
The second box has a higher work done.
C) Organ system.
Your organs are working together to control and keep your body moving!! When a organ starts to do they're job it may need some other organs to help. When this happens it begins the Organ System!
Answer:
total amount of fluoride 3.6 *10^6 g
Explanation:
we know that
volume of reservoir
=
= 2.25*10^6 m^3
denso=ity of water = 1000 kg/m3
mass of water = 1000*2.25*10^6
= 2.25*10^9 kg = 2.25*10^12 g
fluoride 1.6 ppm
total amount of fluoride
= 3.6 *10^6 g
Answer
given,
weight of the oak board = 600 N
Weight of Joe = 844 N
length of board = 4 m
Joe is standing at 1 m from left side
vertical wire is supporting at the end.
Assuming the system is in equilibrium
T₁ and T₂ be the tension at the ends of the wire
equating all the vertical force
T₁ + T₂ = 600 + 844
T₁ + T₂ = 1444...........(1)
taking moment about T₂
T₁ x 4 - 844 x 3 - 600 x 2 = 0
T₁ x 4 = 3732
T₁ = 933 N
from equation (1)
T₂ = 1444 - 933
T₂ = 511 N
Answer:
States of Matter and Kinetic Theory Theory of Kinetic Molecular Dynamics Kinetic energy is the energy possessed by an object as a result of its motion. The Kinetic Molecular Theory explains how molecules interact and how much energy they have. This idea is based on three different matter theories.
