<span>77.2 k is -195.95 C
To convert from Kelvin to Celsius, you simply subtract 273.15 from the temperature. So the expression becomes
c = 77.2 - 273.15 = -195.95</span>
Answer:
average speed and velocity are 0.5m/s (squared)
Answer:
1.92 m/s
Explanation:
Velocity is defined as the distance moved per unit time with consideration of the direction. The direction aspect differentiates speed from velocity since for speed, we don't need to consider the direction.

Distance moved for circular path is equal to its circumference and the circumference is given by
where r is the radius and substituting
for d then

Substituting 5.5 m for r and 18 s for t then

To the nearest hundredth, the velocity is 1.92 m/s
There are different forces acting on an object like nuclear force , gravitational force...plus external forces like friction and other..
