Answer:
19.3
Explanation:
Assuming we have to find Specific gravity of gold.
As we know that specific gravity is defined as the ratio of weight of the object and weight of the water displaced by the object
so it is given by
specific gravity = weight of the object/weight of the water displaced
now we have
weight of the object = (density)(volume)g
weight of object = (19.3)(0.55)g
now weight of the liquid displaced is given by
weight of water displaced = (1 g/cm^3)(0.55ml)g
now we have
specific gravity = (19.3×0.55)/(1×0.55)
specific gravity= 19.3

It’s
that time of year again when the days are wet and cool.
The rainy
season is the best season.
Rain makes up part of Earth’s water cycle.
Water evaporates from streams, lakes, and oceans, then condensation
and
precipitation occur in the form of rain.
Precipitation in the form of
rain is better than snow.
Snow this time of year makes people gloomy.
Rain is a great boon to local farmers.
It helps their crops grow.

The egg was dropped from a height of 24.7 m (free fall motion)
Explanation:
The motion of the egg is a free fall motion (uniformly accelerated motion), so we can use the following suvat equation:
![v^2-u^2=2as](https://tex.z-dn.net/?f=v%5E2-u%5E2%3D2as)
where
v is the final velocity
u is the initial velocity
a is the acceleration
s is the displacement
For the egg in this problem, we have:
u = 0 is the initial velocity
v = 22 m/s is the final velocity
is the acceleration of gravity
s is the vertical displacement (the height from which the egg was dropped)
Solving for s, we find:
![s=\frac{v^2-u^2}{2a}=\frac{22^2-0}{2(9.8)}=24.7 m](https://tex.z-dn.net/?f=s%3D%5Cfrac%7Bv%5E2-u%5E2%7D%7B2a%7D%3D%5Cfrac%7B22%5E2-0%7D%7B2%289.8%29%7D%3D24.7%20m)

Answer:
15min
Explanation:
The speed would be equal to the speed from the walking backwards 5 meter trial and time should be 15 minutes.
