Average velocity during a time interval is
(the straight-line distance between the starting point and ending point,
regardless of the route followed along the way)
divided by
(the length of the time interval)
in the direction
(from the starting point to the finishing point).

Answer:
hi there!!
Explanation:
Nickel 149 pm
Cobalt 152 pm
Calcium 194 pm
Potassium 243 pm
So Potassium is the correct answer
Answer: The mass would be 1000m3 and the volume would be 1000kg
Explanation:
The total gauge pressure at the bottom of the cylinder would
simply be the sum of the pressure exerted by water and pressure exerted by the
oil.
The formula for calculating pressure in a column is:
P = ρ g h
Where,
P = gauge pressure
ρ = density of the liquid
g = gravitational acceleration
h = height of liquid
Adding the two pressures will give the total:
P total = (ρ g h)_water + (ρ g h)_oil
P total = (1000 kg / m^3) (9.8 m / s^2) (0.30 m) + (900 kg /
m^3) (9.8 m / s^2) (0.4 - 0.30 m)
P total = 2940 Pa + 882 Pa
P total = 3,822 Pa
Answer:
The total gauge
pressure at the bottom is 3,822 Pa.
