This is called an organ. Examples of organs are: your heart, brain, lungs, liver, stomach etc.
A professional hockey player, because they would typically have more mass than a fifth grader.
V = 0.9375 m3 is minimum volume .
<h3>What is density ?</h3>
- We use the word "density" to indicate how much space (or "volume") an object or substance occupies in relation to the amount of matter contained therein (its mass).
- Density can also be defined as the quantity of mass per unit of volume. A dense object is one that is both hefty and small.
Given,
1000 kg/m3 = density of water
920 kg/m3 = density of ice
BF = Woman Weight + Slab Weight
Pvg = 75 + Pvg
V = 75 kg / (1000 - 920)
V = 75 / 80
V = 0.9375 m3
Therefore, V = 0.9375 m3 is minimum volume .

Answer:
a. the amount of work done on a system is dependent of pathway
Explanation:
The first law of thermodynamics states that the change in internal energy of a system equals the net heat transfer into the system minus the net work done by the system.
ΔU = Q - W
Where;
Q, the net heat transfer into the system depends on the pathway
W, the net work done by the system also depends on the pathway
But, ΔU, the change in internal energy is independent of pathway
Therefore, the correct option is "A"
a. the amount of work done on a system is dependent of pathway
The tangential velocity of the car is 124.5 m/s
Explanation:
The centripetal acceleration of an object in uniform circular motion is given by:
where
a is the acceleration
v is the tangential velocity
r is the radius of the circle
For the car in this problem, we have:
is the centripetal acceleration
r = 155 m is the radius of the turn
Solving for v, we find the tangential velocity of the car:
