Based on the passage, how is a neurotransmitter different from an action potential? A Neurotransmitters do not carry neural messages, but an action potential does. B Neurotransmitters are chemical, and an action potential is electric. C Neurotransmitters carry signals inside the neuron, and an action potential carries signals between neurons. D Neurotransmitters are "all-or-none," but an action potential can fire halfway.

the answer would be a

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
