Answer:

The minimum speed is 7.5 m/s.

Explanation:

Given that,

Height = 2.87 m

We need to calculate the minimum speed

Using equation of motion

v^2=u^2-2gh

u=\sqrt{2gh}

Where, u = minimum velocity

g = acceleration due to gravity

h = height

Put the value into the formula

u=\sqrt{2\times9.8\times2.87}

u=7.5\ m/s

Hence, The minimum speed is 7.5 m/s.

Elena-2011 [213]


In a cell, protein synthesis  is the primary function of the ribosomes, found in both eukaryotic and prokaryotic cells.

A Ribosome is a cell organelle that makes protein. The location of the ribosome  in a cell determine the kind of protein it makes.  If the ribosome is attached to the endoplasmic reticulum, the proteins made are utilized both  within and outside the cell. If the ribosome is in the cytoplasm, floating freely, then the kind of protein made will be utilized within the cell only.

How do you work out the potential diffrance
timurjin [86]

Answer:

The potential difference is the drop in voltage that occurs across a resistor as current flows through it in a circuit, potential difference or voltage(V) = current (I) *resistance (R), or to abbrevate V = I*R. In this case, I = 5amps and R = 10 ohms, so V = 5 * 10 = 50volts
