What is a Renewable Resource?
When Renewable sources can be found, again and again, similar to how you can plant a tree again to receive food sources and also heat production, they are in turn useful to humans.
When the renewable resources are resources, generally naturally happening, they can replenish to the rate that they can return the used volume and also be swallowed.
A renewable resource will either produce itself naturally through automatic approaches to that resource or through human interaction and guidance.
Therefore, The correct option is 'B'.

You place a book on top of a spring and push down, compressing the spring by 10 cm. When you let go of the book, it is pushed up by the spring. Which statement describes what happens to the energy of the spring book system?
A. The elastic potential energy of the system increases.
B. The gravitational potential energy of the system increases.
C. The kinetic energy of the system decreases.
D. The total energy of the system increases.
Answer:
Eliminate D as there is no nonconservative force, then look at each energies before and after. The speed of the book will increase, so kinetic energy is increasing. The height of the book is increasing, so gravitational potential energy is increasing. However, since the spring is becoming decompressed, the elastic potential energy is decreasing.

How does static electricity apply to car
paint application?
Answer:
For electrostatic paint to be applied, the vehicle needs to be grounded and positively charged. This creates a magnetic attraction to the negatively charged paint. Due to this charge, when the paint leaves the nozzle, it is attracted to the vehicle's charge and will stick to it.

Shawn is doing drills out on the field by pulling a tire behind him for 30 m. If Shawn is applying a net force of
1200 N to pull the tire, then how much work is Shawn doing?
Answer:
The work done by Shawn in moving the tire is 36,000 J
Explanation:
Given;
net force applied by Shawn , F = 1200 N
distance he moved the tire, d = 30 m
The work done by Shawn in moving the tire is calculated as;
W = Fd
Substitute the given values and solve for Work done;
W = 1200 x 30
W = 36,000 J
Therefore, the work done by Shawn in moving the tire is 36,000 J

They did a flu shot from McKinnon at 45° to the horizontal with an initial speed of 25 m/s and that is positioned at a horizontal distance of 50 m from the canyon from which it is shot how long does it take the daredevil to travel the 50 m horizontally
Answer:
The time taken for the daredevil to travel the 50 m horizontally is 2.83 s.
Explanation:
Given;
angle of projection, θ = 45°
initial speed of the projectile, u = 25 m/s
horizontal distance traveled by the projectile, x = 50 m
The time taken for the daredevil to travel the 50 m horizontally is calculated as;
[tex]t =\frac{X}{u_x}[/tex]
where;
[tex]u_x[/tex] is the horizontal component of the velocity = uCosθ
[tex]t =\frac{X}{u Cos \ \theta} \\\\t =\frac{50}{25 \times Cos(45)} \\\\t= \frac{50}{17.678} \\\\t = 2.83 \ s[/tex]
Therefore, the time taken for the daredevil to travel the 50 m horizontally is 2.83 s.

2. Two projectiles thrown from the same point at angles 0,=60° and 02=30° with the horizontal,
attain the same height. What is the ratio of their initial velocities (Voi:Voz)?
Answer:
The answer is below
Explanation:
The maximum height (h) of a projectile with an initial velocity of u, acceleration due to gravity g and at an angle θ with the horizontal is given as:
[tex]h=\frac{u^2sin^2\theta}{2g}[/tex]
Given that the two projectile has the same height.
[tex]For\ the\ first\ projectile\ with\ an\ angle\ \60^0 \ with\ the\ horizontal\ and initial\ velocity\ u_1:\\\\h=\frac{u_1^2sin^260}{2g} =\frac{0.75u_1^2}{2g} \\\\For\ the\ second\ projectile\ with\ an\ angle\ \30 \ with\ the\ horizontal\ and initial\ velocity\ u_2:\\\\h=\frac{u_2^2sin^230}{2g} =\frac{0.25u_2^2}{2g}\\\\\frac{0.25u_2^2}{2g}=\frac{0.75u_1^2}{2g}\\\\0.25u_2^2=0.75u_1^2\\\\\frac{u_1^2}{u_2^2} =\frac{0.25}{0.75} \\\\\frac{u_1^2}{u_2^2}=\frac{1}{3} \\[/tex][tex]\\\frac{u_1}{u_2}=\sqrt\frac{1}{3}[/tex]

Between ball B and ball C, ball ____ has LESS potential energy because ___
a: c;its mass is greater
b: b;its mass is smaller
c: c; its mass is smaller
d: b;its mass is greater
Answer: b
Explanation:
Ec= (1/2)m × v^2
By the formula, you can see that the bigger the mass, the bigger the Cinetic Energy.
b: b; its mass is smaller
Between ball B and ball C, ball B has LESS potential energy because its mass is smaller.
A potential energy, stored energy that depends upon the relative position of various parts of a system. A spring has more potential energy when it is compressed or stretched.
Potential energy is given by formula.
[tex]P.E= m*g*h[/tex]
Since, P.E is directly proportional to mass. Thus, the ball having smaller mass will have the less P.E.
Thus, option b is correct.

A man standing on top of a 30 m tall building throws a brick downwards with a velocity of 12 m/s. Determine the speed of the brick just before it hits the ground.
Answer:
27.1m/s
Explanation:
Given parameters:
Height of the building = 30m
Initial velocity = 12m/s
Unknown:
Final velocity = ?
Solution:
We apply one of the kinematics equation to solve this problem:
v² = u² + 2gh
v is the final velocity
u is the initial velocity
g is the acceleration due to gravity
h is the height
v² = 12² + (2 x 9.8 x 30)
v = 27.1m/s
Which statement describes the relationship between bond strength and the
melting and boiling points of a substance?
A. Substances held together by hydrogen bonding have lower melting
and boiling points than those held together by Van der Waals
forces.
B. Substances held together by ionic bonding have higher melting
and boiling points than those held together by hydrogen bonding.
C. Substances held together by Van der Waals forces have higher
melting and boiling points than those held together by ionic
bonding
O D. Substances held together by ionic bonding have lower melting and
boiling points than those held together by hydrogen bonding.
SUB
Answer: Wrong
Explanation:
The statement that accurately describes the relationship between bond strength and the melting and boiling points of a substance is; "substances held together by ionic bonding have higher melting and boiling points than those held together by hydrogen bonding."
Intermolecular forces refers to forces of attraction that holds molecules together in a particular state of matter. The nature and magnitude of intermolecular forces impacts on the magnitude of the melting and boiling points of substances.
Substances held together by ionic bonding have higher melting and boiling points than those held together by hydrogen bonding. The bonds between ionic substances can only be broken at very high temperature.

A 3.0 g bullet traveling at a speed of 400 m/s enters a tree and exits the other side with a speed of 200 m/s. Where did the bullet's lost KE go, and what was the energy transferred?
Answer:
1800J
Explanation:
Step one:
given data
mass of bullet m= 3g= 0.03kg
initial velocity u = 400m/s
final velocity v= 200 m/s
Step two:
1.The bullet's lost kinetic energy went inside the tree.
2. The energy transferred is computed as
= initial KE- KE final
Initial KE= 1/2mu^2
Initial KE= 1/2*0.03*400^2
Initial KE= 1/2*0.03*160000
Initial KE= 1/2*4800
Initial KE= 2400J
KE final= 1/2mv^2
KE final= 1/2*0.03*200^2
KE final= 1/2*0.03*40000
KE final= 1/2*1200
KE final= 600J
KE transferred = 2400-600
KE transferred= 1800J
