Write the following as full (decimal) numbers without prefixes on the units: (a) 177.3 mm, (b) 26 mv, (c) 537 mg. (d) 36.5 ps, (e) 52.5 nm.

Explanation:

To find the full numbers, we just need to know the decimal representation of the unit prefix.

We know that milli- is one thousandth, this is

So, we can obtain the first three numbers simply by taking this multiple:

a.

b.

c.

pico- is one trillionth, this is

so

d.

finally, nano- is one "one billionth", this is

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
