The Energy is Kinetic Energy.
Kinetic Energy = 1/2*mv², Where m is mass in kg, v is velocity in m/s
Energy is 33750 Juoles, v = 30m/s
1/2*mv² = E
1/2*m*30² = 33750
m = (2*33750) / (30²) Using a calculator
m = 75 kg
Mass of object is 75 kg.
Answer:
Interplanting is the practice of planting a fast-growing crop between a slower-growing one to make the most of your garden space. ... Intercropping enables you to boost the health of all plants because it can enhance soil fertility and cooperation among different plants.
Answer: (5/6) m/s
Explanation:
Distance = 100m
Time taken = 2 min
= 2 × 60 s
= 120 s
Speed = ?
Now,
Speed = distance / time taken
Speed = 100 / 120
Speed = (5/6) m/s
Mechanical or Electromagnetic
Red light would be commonly used due to the longer wavelength
