Answer:
Friction can be minimized by using lubricants like oil and grease and by using ball bearing between machine parts. A substance that is introduced between two surfaces in contact, to reduce friction, is called a lubricant. Fluid friction can be minimized by giving suitable shapes to the objects moving in the fluids.

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
Answer:
Cumulonimbus
Hail development. Hail is a type of strong precipitation, which is shaped in rainstorms mists (Cumulonimbus). Tempests mists comprises of beads of fluid water (at temperatures lower than 0°с, the beads can be in a thermodynamically instable supercooled condition) and ice gems
Explanation:
Answer:
a = 0.01m/s²
Explanation:
V_f = V_0+a*t
V_f = Velocity final
V_0 = Velocity initial
a = acceleration
t = time
a = (V_f-V_0)/t
a = (540m/s-240m/s)/((8hr)*(60min/1hr)*(60s/1min))
a = 0.01m/s²
Whenever you see "-gee" in the description of a point in an orbit,
you know it's talking about an orbit of the Earth. You see the same
piece of a word in "geology" and "geography". "Geometry" began
as the study of measuring places on the Earth, so that you and your
neighbor could agree on where your field ends and his begins, and
if you wanted to buy part of his field from him, the two of you could
go outside, do some measurements, and agree on what area you're
paying him for.
"Perigee" and "apogee" are the points in the orbit of the Moon, or a
TV satellite, or the International Space Station, where the orbiting body
is nearest or farthest from the Earth. "Perigee" is the lowest/nearest point.
"Apogee" is the highest/farthest point.
If the description has "-helion" in it instead of "-gee", then it's talking about
an orbit around the sun, like points in the Earth's orbit. The "-helion" comes
from the Greek word "Helios" for the Sun.
Earth is at perihelion during the first few days of January, and at aphelion
during the first few days of July. (That's right ... nearest to the sun in January,
and farthest from the sun in July.)
