The formula for finding the kinetic energy of an object is:
KE = 0.5MV^2,
Where:
M= Mass
V = Speed
From the information given above,
M = 21 kg
V = 3 m/s
KE = 0.5 * 21 * 9 = 94.5
Therefore, the canoe's kinetic energy is 94.5 J
The correct answers are:
• The solar wind produces the northern and southern lights
• The solar wind disrupts communication systems.
• The solar wind distorts Earth's magnetic field.
Solar winds are geomagnetic stream of charged particles radiated from the outer atmosphere of the sun. All planets are protected from solar winds via magnetic fields but planets that are positioned closer to the sun can experience degeneration of the magnetic field.
Solar winds are capable to distort and even destroy the functioning of communication satellites in outer space, such as radio and tv communication and satellite based internet services.
The effects of solar winds that are visible to naked eye are the Aurora Borealis (the Northern lights) and the Aurora Australis (the Southern Lights).
I’m pretty sure it’s the first option, if not I am so sorry.
