Color I believe because if a diamond was the same color as coal(black) you couldn’t tell a difference
Answer:
skin
Explanation:
this is one of them. it has a sense of touch skin is a organ
Answer:
It's always associated with motion
It can be transferred from one object or body to another
Explanation:
Kinetic energy is the energy due to motion of a body.
- Moving objects possess kinetic energy which is resident in that body.
- As with other forms of energy, it can be transferred from one body to another.
- Kinetic energy can express itself as thermal energy, electrical energy, mechanical energy etc..
- As a body moves, the kinetic energy is increases.
Answer:
(a) number of strands (n) = time (t) ÷ proportionality constant (k)
(b) The time needed for the bacterial to double its initial size is 3.36 hours.
Explanation:
(a) Let the rate (time) be represented by t and the amount (number) of strands of bacteria be represented by n
t is proportional to n, therefore, t = kn (k is the proportionality constant)
Since t = kn, then, n = t/k
(b) Initial amount of strands = 300
Amount of strands after 2 hours = 300 + (300 × 20/100) = 300 + 60 = 360
k = t/n = 2/360 = 0.0056 hour/strand
Double of the initial size is 600 (300×2 = 600)
Time (t) needed for the bacterial to double its initial size = kn = 0.0056×600 = 3.36 hours
