The answer for getting and using every,reproducing and maintaining structure are out of life
Answer:
Explanation:
Given that,
The Camden holds a volume of
V = 2,000,000 gallons
At a height of
h = 24 m
We want to find the potential energy.
And potential energy can be calculated using
P.E = mgh
Where
m is the mass
g Is the acceleration due to gravity
h Is the height.
Given that,
Then volume is
V = 2,000,000 gallons
From research.
1 gallon ≈ 3.785 kg
Then,
2,000,000 gallons = 2,000,000 × 3.785 kg
So,
P.E = mgh
P.E = 2,000,000 × 3.785 × 9.81 × 24
P.E = 1.782 × 10^9 J.
Gravity<span> - is the force by which a planet or other body draws objects toward its center. The force of gravity keeps all of the planets in orbit around the sun.
Air resistance - </span>By definition, air resistance describes the forces that are in opposition to the relative motion of an object as it passes through the air. These drag forces act opposite to the oncoming flow velocity, thus slowing the object down. Unlike other resistance forces, drag depends directly on velocity, since it is the component of the net aerodynamic force acting opposite to the direction of the movement.
<span>Another way to put it would be to say that air resistance is the result of collisions of the object’s leading surface with air molecules. It can therefore be said that the two most common factors that have a direct effect upon the amount of air resistance are the speed of the object and the cross-sectional area of the object. Ergo, both increased speeds and cross-sectional areas will result in an increased amount of air resistance.</span>
Answer:
v = 27.3 m/s
Explanation:
Given that
Acceleration ,a= 4.2 m/s²
Time ,t= 6.5 s
Lets take the maximum speed gain by Thomson's= v
We know that ,if acceleration is constant then the speed v is given as
v= u + a t
v=final speed
u=initial speed
a=acceleration
t=time
Here the initial speed of Thomson's ,u = 0 m/s
Now by putting the values in the above equation we get
v= 0 + 4.2 x 6.5 m/s
v = 27.3 m/s
Therefore the maximum speed gain by Thomson will be 27.3 m/s.
1) d = V*t >>>as you double the av. speed the distance become doubled.
2) after you draw the victors you will find the total displacement = 1 meter to the left.
3) V =d/t =( 8km)/(1.25hr) = 6.4km/hr
