Answer:
1 km
Explanation:
= Gap between antennas = 600 m
= Frequency = 1 MHz
= Distance to receiver = 2 km
c = Speed of light = 
Wavelength is given by
Distance to be moved is given by
The distance to be moved is 1 km north.
The answer is air pollution
Answer: Planting a tree belt.
Explanation:
The most effective method by which the desertification of the soil can be controlled is by planting more and more trees.
The process of desertification occurs when there is a loss of vegetation, water bodies and animals from a particular area. Loss of trees makes the area look like desert.
So, planting trees along with some irrigation will help to cope with problem.
The kinetic energy, potential energy and total mechanical energy possessed by the skydriver are 1.5 × 10⁵ Joule, 6.7 × 10⁵ Joule and 8.2 × 10⁵ Joule respectively.
To find the answer, we need to know about the expression of kinetic energy and potential energy.
<h3>
What are the expressions of kinetic energy and potential energy?</h3>
- Mathematically, kinetic energy= 1/2 × mass × velocity²
- Gravitational potential energy near the earth surface= mass × g × height on the earth surface
<h3>What's the kinetic energy, potential energy and total mechanical energy of the 78kg skydriver at 870 m on earth surface with 62 m/s velocity?</h3>
- Kinetic energy= 1/2 × 78 × 62² = 1.5 × 10⁵ Joule
- Potential energy= 78×9.8×870= 6.7× 10⁵ Joule
<h3>What's the total mechanical energy?</h3>
- Mechanical energy= kinetic energy+ potential energy
- 1.5 × 10⁵ Joule + 6.7× 10⁵ Joule = 8.2× 10⁵ Joule
Thus, we can conclude that the kinetic energy, potential energy and total mechanical energy possessed by the skydriver are 1.5 × 10⁵ Joule, 6.7 × 10⁵ Joule and 8.2 × 10⁵ Joule respectively.

Answer:
Potential energy
Explanation:
Potential energy is the energy stored within an object, due to the object's position, arrangement or state. Potential energy is one of the two main forms of energy, along with kinetic energy.
