Answer:

10 m/s/s or m/s²

Explanation:

Acceleration can be calculated by using the formula;

a = v - u/t

Where;

a = acceleration (m/s²)

v = final velocity (m/s)

u = initial velocity (m/s)

t = time (s)

In other terms, acceleration (a) can be represented as ∆V/t.

According to this question, a ball accelerates from 10 m/s (u) to 30 m/s (v) in 2 seconds. Hence, the acceleration of the ball is as follows:

a = 30 - 10/2

a = 20/2

a = 10m/s².

Dendrite; axon; synapse

These are parts of the neuron which is considered as the basic unit of nervous system. The cell responsible for receiving sensory input from the external environment. The stimulus will be transported in an electrical signal via neuronal parts. Axon transmit signal to the other neuron. Dendrites are the receiving part of the neuron. Synapse is the space between each neuron where elctrical impulse is converted into a chemical signal via neurotransmitters.
