What is the Natural Resources Defense Council?
NRDC strives to rid our food, air, water, and household products from toxic chemicals.
40 percent of food produced in the US is trashed each year according to the Natural Resources Defense Council.
Food decomposes anaerobically and releases methane emissions, a greenhouse gas that is 28 times more potent than carbon dioxide over a 100-year period and 84 times more on a 20-year scale , when food waste ends up in landfill.
Worldwide, some percent of greenhouse gas emissions result from food waste alone.
Therefore,
Food is the largest contributor to land pollution.

A container with a mass of 5 kg is lifted to a height of 8 m. How much work is done by the gravitational force
Answer:
work done=392J
Explanation:
work done =Mgh
DATA
M=5kg
g= 9.8
h=8m
W=Mgh
W=5*9.8*8
W=392J
The work done by the gravitational force is equal to -400 J.
What is gravitational force?The gravitational force can be described as a force that attracts a body towards the center of the earth or any physical object that has mass. Every object has mass and exerts a gravitational pull on another object with mass.
Given, the mass of the container, m = 5 Kg
The height from the ground level, h = 8 m
The work done can be calculated by using the below-mentioned formula:
[tex]W = m\times g\times h[/tex]
Where g is the gravitational acceleration.
As the container is lifted in the upward direction therefore the value of the g will be negative.
Substitute the values of m, g, and h in the above formula:
W = 5 × (-10) × 8
W = -400 J.
The negative sign shows that the work is done against the gravitational force.
Therefore, the work done by the gravitational force is equal to -400 J.

A car is traveling with 90km/hr and another car with 20m/s in opposite direction. Calculate the relative velocity.
Answer:
Vba = -20 m/s - 25 m/s = -45 m/s
Vab = 25 m/s + 20 m/s = 45 m/s
Explanation:
Relative Velocity
The relative velocity of object B with respect to object A (Vba) measures the velocity of B in the rest frame of object A.
It's calculated as:
Vba = Vb - Va
The velocity of car B is Vb=-20 m/s and the velocity of car A is Va=90 Km/h.
Converting Va to m/s:
Va = 90 Km/h * 1000/3600 = 25 m/s
Thus, the relative velocity of B with respect to A is:
Vba = -20 m/s - 25 m/s = -45 m/s
And the relative velocity of A with respect to B is:
Vab = 25 m/s + 20 m/s = 45 m/s

A 1500 kg car has an applied forward force of 5000 N and experiences an air resistance of 1250 N. What is the car's acceleration?
Answer:
[tex]2.33\ m/s^2[/tex]
Explanation:
Net Force
According to the second Newton's law, the net force exerted by an external agent on an object of mass m is:
Fn = m.a
Where a is the acceleration of the object. The net force is the sum of the individual vector forces applied to the object.
The m=1500 Kg car has two horizontal forces applied: the forward force of 5000 N that causes the movement and the air resistance force of 1250 N that opposes motion.
The net force is Fn = 5000 N - 1500 N = 3500 N
To find the acceleration, we solve the equation for a:
[tex]\displaystyle a=\frac{Fn}{m}[/tex]
[tex]\displaystyle a=\frac{3500}{1500}[/tex]
[tex]\boxed{a = 2.33\ m/s^2}[/tex]
The car's acceleration is [tex]a = 2.33\ m/s^2[/tex]

How do bubbles support the atomic theory?
A. The bubbles are lighter than air.
B. There is matter that cannot be seen inside the bubbles.
C. The bubbles will burst before long.
D. The bubbles cannot be broken into smaller pieces.
Answer:
The answer is probably B or C
Option B supports the atomic theory. Thus, this option is correct.
Atomic theory is the theory which states that matter is composed of particles called atoms. It tells us that all the matters are made of very tiny particles called atoms and all atoms of the same kind have the same size in any object.
Let's look at all the options given,
A-The bubbles are lighter than air- The bubble consists of water and air thus they are not lighter than air. This statement does not tell anything about the atomic theory. Hence this option is not correct.B. There is a matter that cannot be seen inside the bubbles-The bubble is made up of two kinds of atoms one is oxygen and another is hydrogen. When we feel air into a soap bubble solution molecules want to attract to each other again so they wrap around the burst of air to attach to each other again. These atoms cannot be seen inside the bubbles but this option support the atomic theory. Thus, this option is correct.C. The bubbles will burst before long-In the bubble there is water. When this water loss in some way the bubble pops up. This water can be lost when it comes to contact with dry fingers or objects. It can be burst when the atmosphere is very dry. All the atoms are attracted towards. D. The bubbles cannot be broken into smaller pieces-This option does not support the atomic theory thus this is not the correct option.
Hence the option B supports the atomic theory. Thus, this option is correct.

Which of the following is the minimum amount of work done by a hydraulic lift
to raise a 150-kg aluminum block 2.0 m vertically?
Answer: 300 J
Explanation:
Force = 150 KJ
Distance = 2.0 m
The minimum amount of work done by a hydraulic lift to raise a 150-kg aluminum block 2.0 meters vertically would be 2940 Joules, as the work done is the product of the force applied to the displacement of the object, therefore the correct answer is option B.
What is work done?The total amount of energy transferred when a force is applied to move an object through some distance
The work done is the multiplication of applied force with displacement.
Work Done = Force × Displacement
As given in the problem we have to find out the minimum amount of work done by a hydraulic lift to raise a 150-kg aluminum block 2.0 meters vertically.
The minimum work done = 150 × 9.8 × 2
= 2940 Joules
Thus, The minimum amount of work done by a hydraulic lift to raise a 150-kg aluminum block 2.0 meters vertically would be 2940 Joules.

what is it called when a magnet causes the atoms in a non-magnetic metal to line up and act like a magnet?
a: oriented magnet
b: permanent magnet
c: non-magnet
d: induced magnet
Answer:
I think It's induced magnet
Explanation:
Because a magnet and non magnet can be chicken nuggets
If a magnet causes the atoms in a non-magnetic metal to line up and act like a magnet, the non magnet is said to be an induced magnet by the magnetic induction by a permanent magnet.
What is magnetic induction ?A permanent magnet is made of ferromagnetic materials which are having permanent magnetic properties. The magnetic field lines from permanent magnet always align with an applied magnet.
As in the case of dipole molecules capable of inducing a polarity to a nonpolar molecule, a magnetic field by a strong magnet can induce a magnetic property to a nonmagnet.
The induced magnetic field only reside in the object as long as the induction source is there. For example the a rotating electric filed causes magnetic moment in a nonmagnet.
