71% of the earth is water
Answer:- Input for computer-based weather prediction models;
- Local severe storm, aviation, fire weather, and marine forecasts;
- Weather and climate change research;
- Input for air pollution models;
- Ground truth for satellite data
Explanation:
The water is likely to be dirty or not clear enough. I mean, if you through a key into the body of water, you can't see the key at the bottom of the water body because of impurities which make the water look dirty or not visible or transparent enough.
Answer:
Explanation:
It is given that,
Mass of the particle, m = 2 kg
Force acting on the particle, F = -36 N (negative axis)
The position of the particle as a function of time t is given by :
Velocity, 
Acceleration, 
At t = 3 s
Force acting on the particle is given by :
F = ma
On solving above equation, . It has a unit same as acceleration.
Hence, this is the required solution.
Answer:
3.55kg
Explanation:
K. E = ½mv²
Where m = mass, v = velocity
K. E = 300J
v = 13m/s
Therefore,
K. E = ½mv²
300 = ½ × m × 13²
Multiply both sides by 2
600 = m × 169
Divide both sides by 169
m = 600 ÷ 169
mass = 3.55kg
