Answer:
1.The eyes, a sensory organ, see the ball.
2.Sensory nerves transmit the information to the brain.
3.The brain processes the information.
4.The brain sends signals to the motor nerves.
5.Motor nerves carry the signal to the hand muscles.
Explanation:
When we receive a stimulus by any of our 5 senses (sight, touch, smell, hearing or taste) our body will react to this. Once that the stimulus is received ( in this case seeing the ball) a signal is send through the sensory nerves to the brain. In the brain the information will be processed and an answer will be given through the motor nerves in order to move the muscles and catch the ball. All this process is made in seconds.
Explanation:
The half life is the time taken for a half of a radioactive material or substance to decay to half.
After the passing of the half-life, only half of the original material will remain. Now, let us follow the half-life sequence of this decay;
One half-life
Original: 1000cm
one half life = 500cm
Two half-lifes
Original: 500:
half-life = 250cm
Three half-lifes
Original : 250cm
Half life = 125cm
Four half-lifes
Original: 125cm
Half life = 62.5cm
Five half-lifes
Original: 62.5cm
Half-life = 31.25cm
Six half-lifes
Original: 31.25cm
Half-life = 15.625
