Here it is given that initial speed of the package will be same as speed of the helicopter

displacement of the package as it is dropped on ground

acceleration is due to gravity

now by kinematics



by solving above equation we have

so it will take 5.2 s to reach the ground
Phytophotodermatitis happens when certain plant chemicals cause the skin to become inflamed following exposure to sunlight.
Density is varying through the world’s oceans. The density of ocean water is not uniform.
Answer:
The answer is 8 N
Explanation:
The Lorentz force for a current carrying wire is
f = I * L x B
So, for magnetic forces to manifest the current must not be parallel to the magnetic field. So the cases where the wire is parallel to the field would result in a force of zero applied on the wires by the magnetic field because the cross product becomes zero.
For the perpendicular cases:
f = I * L * B
f = 80 * 0.1 * 1 = 8 N
