Answer:
1) The angle of deflection will be less than 45° ( C )
2) The angle of deflection will be greater than 45° but less than 90° ( E )
Explanation:
1) Assuming that the force applied has a direction which is perpendicular to the Earth's magnetic field
∴ Fearth > Fapplied hence the angle of deflection will be < 45°
2) when the Fearth < Fapplied
the angle of deflection will be : > 45° but < 90°
Answer: the system of varying successive crops in a definite order on the same ground, especially to avoid depleting the soil and to control weeds, diseases, and pests.
Explanation:
2.6 seconds (If acceleration due to gravity is taken 10 m/s^2) or 2.65 (If acceleration due to gravity is taken 9.8 m/s^2)
Answer:
W=-1881.6J
Explanation:
we have that the change in the mass is

by solving the differential equation and applying the initial conditions we have

by solving for c and d
d=60
c=0.75
The work needed is
W = m(t) gh
by integrating we have

hope this helps!!
