An ice cube causes hot coffee to become cool because the amount of coldness contrasts the hot coffee to make it a little cooler
Answer:
= 3521m/s
The tangential speed is approximately 3500 m/s.
Explanation:
F = m * v² ÷ r
Fg = (G * M * m) ÷ r²
(m v²) / r = (G * M * m) / r²
v² = (G * M) / r
v = √( G * M ÷ r)
G * M = 6.67 * 10⁻¹¹ * 5.97 * 10²⁴ = 3.98199 * 10¹⁴
r = 32000km = 32 * 10⁶ meters
G * M / r = 3.98199 * 10¹⁴ ÷ 32 * 10⁶
v = √1.24 * 10⁷
v = 3521.36m/s
The tangential speed is approximately 3500 m/s.
Answer:
the skater is falling bc of gravity and kinetic energy
Explanation:
The formula for Fahrenheit and Celsius conversion is
T(°F)<span> = </span>T(°C)<span> × 1.8 + 32
where T is temperature in F or C ( Fahrenheit or Celsius whatever is the case)
</span>This means that keeping this FORMULA in mind we can add different values to it and accordingly convert values from one to another.
Some examples of fahrenheit conversions to Celsius are :
32°F = 0°C using F = (0 x 1.8) + 32
Answer:
Explanation:
If you drop a ball from
the top of a building it
gains speed as it falls.
• Every second, its
speed increases by
10 m/s.
• Also it does not fall
equal distances in
equal time intervals
• If the acceleration = 0 then the velocity is
constant. [remember that acceleration is
the rate of change of velocity]
• In this case the distance an object will
travel in a certain amount of time is given
by distance = velocity x time
• For example, if you drive at 60 mph for
one hour you go 60 mph x 1 hr = 60 mi.
