Explanation:
The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre. For example, the density of water is 1 gram per cubic centimetre, and Earth's density is 5.51 grams per cubic centimetre.
Answer: Addition of
salt bridge
To generate a standard
electromotive force, an addition of salt bridge is essential to help maintain
electrical neutrality within the internal circuit and prevent the cell from
rapidly running its reaction to equilibrium.
In addition, salt bridge contains potassium
sulfate, an inert electrolyte where its ions will diffuse into the separate half-cells
to stabilize the building charges at the electrodes and produce electricity.
To find the maximum height you have to calculate the initial velocity in the y axis..
to do that resolve the velocity vector in the y direction
which is equal to
[email protected]27*√3/2 = 23.4 m/s
thus using kinematics.
v^2 = u^2 + 2as
23.4*23.4 /19.6 = s
27.96 that's 28 m approximately
We would calculate the magnitude by applying pythagorean theorem:
The angle between two vectors is given by the formula:
In two dimensional, the x axis of vector form is:
