Answer: The height of rollercoaster cart above the ground is 1.53 m.
The velocity of rollercoaster cart is 5.29 m/s.
Explanation:
Potential energy is the energy occupied by a substance due to its position. Formula for potential energy is as follows.
P.E = mgh
where,
m = mass of substance
g = gravitational constant =
h = height
Substitute the values into above formula as follows.
Hence, the height of rollercoaster cart above the ground is 1.53 m.
Kinetic energy is the energy occupied by the motion of a substance. Formula for kinetic energy is as follows.
where,
m = mass of substance
v = velocity of substance
Substitute the values into above formula as follows.
Hence, the velocity of rollercoaster cart is 5.29 m/s.
Answer:
Explanation: The periodic table contains rows and columns. To find how many valence electrons are in an element, simply locate the column number that it is in, and that determines the number of valence electrons in an element. This rule works only for elements excluding the transition metals
