Answer:
See below ~
Explanation:
The fact that water is attracted to itself, a property called <u>cohesion</u>, leads to another important property, the liquid form of water is <u>more</u> dense than the solid form. As water solidifies into ice, the molecules must move apart in order to fit in to a crystal lattice structure, causing water to expand as it freezes. Because of this, <u>ice floats</u> and water sinks, which keeps the oceans liquid and prevents them from freezing solid from the bottom up.
Heredity is passing on physical traits to your offspring and if you had parents that had a disease it can effect you that can later affect your physical fitness
Answer:
A & B
Explanation:
A & B Would be the right answer since Morse code cannot be represented through the height of the fire.
Answer:
4 cm/s².
Explanation:
From the question given above, the following data were obtained from it:
Initial velocity (u) = 0 cm/s
Final velocity (v) = 40 cm/s
Time (t) = 10 s
Acceleration (a) =?
Acceleration is simply defined as the rate of change of velocity with time. Mathematically, it is expressed as follow:
Acceleration (a) = Change in velocity /time
Acceleration (a) = [final velocity (v) – initial velocity (u)] /time (t)
a = (v – u) /t
With the above formula, we can obtain the acceleration of the ball as follow:
Initial velocity (u) = 0 cm/s
Final velocity (v) = 40 cm/s
Time (t) = 10 s
Acceleration (a) =?
a = (v – u) /t
a = (40 – 0) / 10
a = 40/10
a = 4 cm/s²
Therefore, the acceleration of the ball is 4 cm/s²
