Answer : The pressure of the liquid at depth of 48 ft below the surface of fluid is, 21 psi.
Explanation : Given,
The pressure of the liquid at depth 8 ft = 3.5 psi
Now we have to calculate the pressure of the liquid at depth 28 ft.
According to the question,
As, the depth of 8 ft below the surface of a stagnant fluid has pressure = 3.5 psi
So, the depth of 48 ft below the surface of a stagnant fluid has pressure = 
Therefore, the pressure of the liquid at depth of 48 ft below the surface of fluid is, 21 psi.
I believe number 26 if in correct is product.
Answer
512kj/mole
Explanation:
What is the work function of gold metal in kJ/mol if light with λ = 234 nm is necessary to eject electrons?
The energy can be calculated using below expresion;
E = hc/λ
Where h= planks constant= 6.626 x 10^-34
c= speed of light= 3 x 10^
λ= wavelength
hc= (6.626 x 10^-34 x 3 x 10^ 8)
=
A higher temperature makes the particles move faster, that makes them collide more often. The answer would be this: "It increases the average kinetic energy and number of collisions per minute."
Answer:
E to F
Explanation:
We know that v = dx/dt
and a = d²x/dt²
Decreasing velocity means deceleration or negative acceleration,
therefore d²x/dt²<0
i.e the portion where the graph is having its curvature downwards like an inverted u, from graph E to F portion looks like that.
Therefore in the portion E to F velocity decreases.
