Idk I need to answer a question to ask more so thanks bye
Answer:
Nervous system messages travel through neurons as electrical signals. When these signals reach the end of a neuron, they stimulate the release of chemicals called neurotransmitters. Neurotransmitters travel across synapses, spaces between neurons or between neurons and other body tissues and cells.
Explanation:
At first we have to find the time index, but you have to remember that time does not depend on mug's horizontal velocity. In this case : D=1/2∗g∗t2=1.18 where the in. velocity is 1.2/t.
Of course the mug velocity will be the same as previous one :
v=g*t
Then we have θ=tan−1(vy/vx) so that you can easily find what you need using trigonometry.
Answer: he used a compass to find the direction of the magnetic field
