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.
Answer:
58.8 Hz
Explanation:
The relationship between frequency and period of a wave is
where
f is the frequency
T is the period
For the wave in this problem, we know its period:
T = 0.017 s
Therefore, its frequency is
Explanation:
Given that,
Weight of the friend, W = 600 N
When the friend sits on the metal frame it bends downward 4 cm, we can say that the compression in the it is 4 cm or 0.04 m
To find,
Spring constant for this chair or k
Solve :
The weight of an object is equal to the force exerted by the gravitational force, F = 600 N
According to Hooke's law, the force exerted by the spring is given by :
F = kx
k is the spring constant
k = 15000 N/m
Therefore, the spring constant of the spring is 15000 N/m.
Yes. According to the coach's mathematical criteria, Tommy had a great season.
Sadly, Tommy doesn't even know it. His tone-deaf coach decided to describe success in terms that are absurd for 7-yr-olds, as well as for most of their parents.
