Excess fertilizer use results in nutrient pollution by effecting the nutrition values of the plants we eat.
Cutting down trees more likely to result in air pollution by an increase in greenhouse gases.
Pouring oil in drain creates water pollution which is not a nutrient source.
charge = current * time
q = 15 * 300 [5 min = 300 sec ]
q = 4500 C
Answer:
<em>1.49 x </em>
<em></em>
<em></em>
Explanation:
Kepler's third law states that <em>The square of the orbital period of a planet is directly proportional to the cube of its orbit.</em>
Mathematically, this can be stated as
∝ 
<em>to remove the proportionality sign we introduce a constant</em>
= k
k = 
Where T is the orbital period,
and R is the orbit around the sun.
For mars,
T = 687 days
R = 2.279 x
for mars, constant k will be
k = 
= 3.987 x 
For Earth, orbital period T is 365 days, therefore
= 3.987 x x
= 3.34 x 
R =<em> 1.49 x </em><em></em>
1. What is the weight of this objects?
Weight is simply the product of mass and gravitational
acceleration. Therefore the weight is:
w = 20 kg * 9.81 m/s^2
w = 196.2 kg m/s^2 = 196.2 N
2. After 5 seconds, how has the object fallen and what is its
speed at this instant?
We can use the formula:
<span>y = v0 t + 0.5 g
t^2</span>
v = v0 + g t
where v0 = 0 since the object starts from rest, y is the
distance it fell, t is time
y = 0 + 0.5 * 9.81 * 5^2 = 122.625 m
<span>v = 0 + 9.81 * 5 = 49.05 m/s</span>
c. Wind power can turn turbines to generate electrical power.
Explanation:
The correct statement of all is that wind power can turn turbines to generate electrical power.
This is simply the way wind energy from waves are usually harnessed to produce electricity.
- When a metallic conductor passes in between magnetic fields, it induces and generates electricity as it turns.
- This is how electricity generating plants are fashioned.
- Geothermal energy is not generated from moving water. It is produced from heat within the earth brought to the surface. Power from moving water is hydroelectric power.
- Oil is a non-renewable resource
- Propane is a non-renewable resource
