Answer:
9.6 ft
Explanation:
Distance is inversely proportional to weight
distance = k / (weight), where
k is a constant
or you could say,
distance * weight = k
In this scenario,
120 * 16 = 200 * distance
On rearranging, making, distance the subject of formula, we have
Distance = 120 * 16 / 200
Distance = 1920 / 200
Distance = 9.6 ft
So the 200 pounds person should sit 9.6 feet away from the centre to balance the see saw
An object held in place by gravity
Positive Impact
1. Going digital has allowed business to use less paper hence saving trees which is good for the environment.
2. Technology has also allowed a shift from hydrocarbon fuel cars to battery-powered cars. This saves the environment from carbon emissions.
Negative Impact
1. Technology has caused an increase in gadgets that pollute the environment when improperly disposed of. This waste can be more toxic than other traditional wastes.
2. Increased technology use has resulted in an increased energy demand. This has resulted in a strain on natural resources and have a negative impact on the environment.
Answer:
11×10⁵ J
Explanation:
From the question given above, the following data were obtained:
Mass (m) = 1000 kg
Height (h) = 110 m
Acceleration due to gravity (g) = 10 m/s²
Potential energy (PE) =?
The potential energy of the roller coaster can be obtained as follow:
PE = mgh
PE = 1000 × 10 × 110
PE = 11×10⁵ J
Therefore, potential energy of the roller coaster is 11×10⁵ J
answer: Atomic number and number of protons
Fluorine is an element in periodic table. Fluorine has 9 protons. we know that atomic number of an atom is given by number of protons. Hence, the atomic number of Fluorine is 9. In a neutral atom, number of protons is equal to number of electrons but in the question no information is given on atom being neutral. The atomic mass is equal to the sum of number of neutrons and number of protons. No information is given about neutrons as well. So, we come to know only about atomic number and number of protons from the given information.
