The nervous system has three general functions: a sensory function, an interpretative function and a motor function.
1. Sensory nerves gather information from inside the body and the outside environment. The nerves then carry the information to the central nervous system (CNS).
2. Sensory information brought to the CNS is processed and interpreted.
3. Motor nerve cells convey information from the CNS to the muscles and glands of the body.
The nervous system is responsible for coordinating all of the body's activities.
<h3><u>Answer;</u></h3>
<h3><u>Explanation;</u></h3>
- Light may have both <u><em>wave or particle properties.</em></u>
- <u><em>According to wave theory of light, light behaves like a wave</em></u>. Light is an electromagnetic wave which means it does not require a material medium for transmission. Just like electromagnetic waves light possess both magnetic field and electric fields.
- <em><u>Light waves displays a transverse type of a wave</u></em> in which it oscillates in a similar direction as that of the wave travel. Due to these characteristics of a wave light can undergo <em><u>diffraction and also interference</u></em>.
<h2>
The average force acting on the ball is 1075 N in the direction of travel of ball.</h2>
Explanation:
Force is given by rate of change of momentum.
Mass of soccer ball = 430 g = 0.43 kg
Initial velocity = 0 m/s
Final velocity = 25 m/s
Change in momentum = 0.43 x 25 - 0.43 x 0
Change in momentum = 10.75 kg m/s
Time taken = 0.01 s
Rate of change of momentum = Change in momentum ÷ Time
Rate of change of momentum = 10.75 ÷ 0.01
Rate of change of momentum = 1075 N
Force = 1075 N
The average force acting on the ball is 1075 N in the direction of travel of ball.
Answer:
Explanation:(1) a constitution is a supreme law of the land, (2) a constitution is a framework for government; (3) a constitution is a legitimate way to grant and limit powers of government officials. Constitutional law is distinguished from statutory law.
Answer:
-1.03 m/s²
Explanation:
Acceleration: This can be defined as the rate of change of velocity. The S. I unit of acceleration is m/s².
Mathematically, acceleration is expressed as
a = (v-u)/t ........................ Equation 1
Where a = acceleration, v = final velocity, u = initial velocity, t = time.
Given: u = 13.60 m/s, v = 7.20 m/s t = 6.2 s.
Substituting into equation 2
a = (7.20-13.60)/6.2
a = -6.4/6.2
a = -1.03 m/s²
Note: a is negative because, the hockey puck is decelerating.
Hence the average acceleration = -1.03 m/s²
