By definition, we have to:
Digestion is the transformation of foods that are ingested into simpler substances to be absorbed.
Digestion has different processes:
1) Mechanical processes to reduce the size of food.
2) Chemical processes to reduce the size of the particles and prepare them for absorption.
Therefore, the energy derived from the digestion process is the chemical energy.
Answer:
The energy derived from the digestion of food is chemical energy.
It is Potential energy it's at rest
Answer:
Explanation:
Speed of car =22.5miles/hr
U=22.5miles/hour
Applied brake and come to rest
Final velocity, =0
t, =2sec
Given that,
Speed=distance /time
Then,
Distance, =speed, ×time
Converting mile/hour to m/s
Given that
Use: 1 mile= 1600 m, 1 h= 3600s
22.5miles/hour × 1600m/mile × 1hour/3600s
Therefore, 22.5mile/hour=10m/s
Using speed =10m/s
Distance =speed ×time
Distance=10×2
Distance, =20m
The distance travelled before coming to rest is 20m.
Answer:
a)
b)
c)
Explanation:
From the question we are told that:
Initial speed of 1st ball
Mass of 1st ball
Mass of 2nd ball
Initial speed of 2nd ball
Final speed of 2nd ball
Angle of collision
a)
Generally the equation for law of conservation is mathematically given by
The final velocity is given as
b)
Generally the equation for law of conservation is mathematically given by
c)
Generally the equation for kinetic energy is mathematically given by
1st Ball
2nd ball
Therefore the change in the total kinetic energy of the two balls as a result of the collision is
Answer: A.) sensor
Explanation:
Homeostasis is the ability of the organism's inner body to regulate the internal environment in stable state with respect to the changes occurring in the external environment. It is usually done by the feedback controls.
The maintenance of homeostasis within the body is essential. The following are the factors which controls the homeostasis. These includes:
1. Stimulus: It generate a response. It is an external factor which brings change in the internal body of the organism.
2. Receptor/ sensor: It detects the external stimulus and responds to the change.
3. Control center: The information from the receptor travels along the afferent pathway towards the control center. The function of the control center is to determine the response and controls the action.
4. Effector: The information from the control center travels down the efferent pathway to the effector. The function of the effector is to balance the stimulus to regulate and maintain homeostasis.
