A plane is traveling at 80 m/s. To prepare for landing, it decreases its speed to 50 m/s in 120 s.
emmainna [20.7K]

Answer:

The deceleration of the plane is 0.25 m/s^{2}.

Explanation:

Deceleration is the converse of acceleration.

From first law of motion, we have;

v = u + at

where: v is the final velocity, u is the initial velocity, a is the acceleration and t is the time taken.

Thus,

v = 50 m/s

u = 80 m/s

t = 120 s

50 = 80 + 120a

50 - 80 = 120a

-30 = 120a

a = \frac{-30}{120}

  = -0.25

a = -0.25 m/s^{2}

The deceleration of the plane is 0.25 m/s^{2}.

A neuron transmits information by the secretion of hormones. True or False
grandymaker [24]

Answer:

The given statement is false.

A neuron is the basic structural and functional unit of the nervous system. It helps in transmitting information from one neuron to another neuron, gland, or muscle cell.

The conduction of nerve impulse is electrochemical in nature. It transmits the impulse electrically through the axon the nerve cells and chemically through synapses (gap between two nerves cells).

The axon terminals of pre-synaptic nerve cell release chemical messengers (also called neurotransmitters) in the synaptic cleft. These messengers then bind to the receptors present on the post-synaptic nerve cell and regenerate the nerve impulse.
