Answer:
initial velocity = 0 m/s
final velocity = 4.92 m/s
constant acceleration so,
(a) average velocity =
(initial velocity + final velocity)/2
(b) distance = average velocity x time
substitute and calculate
Explanation:
HOOE ITS HELP ;)
Answer:
In order to make a sound wave have a higher pitch you increase the frequency.
In order to increase the volume of a sound wave, you have to increase the amplitude.
Hope this helps!
Symbol of Phospate: PO₄³⁻
Answer:
The strength of gravity on Pluto is 0.6 m/s²
Explanation:
The given mass of the shoe = 0.5 kg
The weight of the shoe (on Pluto), W = 0.3 N
Therefore, given that weight, W = Mass × The acceleration due to gravity, We have;
The strength of gravity = The force gravity applies to each unit of mass = The acceleration due to gravity (in m/s²)
The weight of the shoe, W = The mass of the shoe × The strength of gravity on Pluto
Substituting the known values, gives;
0.3 = 0.5 × The strength of gravity on Pluto
∴ The strength of gravity on Pluto = 0.6 m/s².
Answer: A. If the surface aquifer has a high water table
Explanation:
The water table refers to the water level underground. If it is high, it means that the water underground is close to the surface such that if a well was dug, it would not need to be dug too far for water to be seen.
When heavy rain falls, flooding is avoided if the water is either able to run off efficiently or if the ground is able to absorb the water. When the water table is high, it means that the ground will not be able to absorb much because the water is already close to the surface which means that should heavy rain fall, there will most likely be a flood.
