Answer: Potential Energy: PE = m x g x h Mass: m = PE / (g x h) Acceleration of Gravity: g = PE / (m x h) Height: h = PE / (m x g) Where, m = Mass, g = Acceleration of Gravity h = Height Gravitational Acceleration of the earth is 9.8 m/sec2.
Explanation:
Answer:
Explanation:
It is given that,
Speed of one quoll around a curve, v = 3.2 m/s (maximum speed)
Radius of the curve, r = 1.4 m
On the curve, the centripetal force is balanced by the frictional force such that the coefficient of frictional is given by :
So, the coefficient of static friction between the quoll's feet and the ground in this trial is 0.74. Hence, this is the required solution.
Answer:
Hydrogen (H), a colourless, odourless, tasteless, flammable gaseous substance that is the simplest member of the family of chemical elements.
Explanation:
The gap between the two flasks is partially evacuated of air creating a near vacuum which significantly reduces heat transfer by conduction or convection
