Answer:
88.34 N directed towards the center of the circle
Explanation:
Applying,
F = mv²/r................... Equation 1
F = Force needed to keep the mass in a circle, m = mass of the mass, v = velocity of the mass, r = radius of the circle.
But,
v = 2πr/t................... Equation 2
Where t = time, π = pie
Substitute equation 2 into equation 1
F = m(2πr/t)²/r
F = 4π²r²m/t²r
F = 4π²rm/t²............. Equation 3
From the question,
Given: m = 0.8 kg, r = 0.7 m, t = 0.5 s
Constant: π = 3.14
Substitute these values into equation 3
F = 4(3.14²)(0.7)(0.8)/0.5²
F = 88.34 N directed towards the center of the circle
The standard cell potential helps to determine the oxidative and reductive strength of species. All the species that lie below the Standard Hydrogen Electrode in the standard cell potential table are stong oxidizing agents and are highly electronegative while those that are above the Standard Hydrogen Electrode are either weak oxidants or reducing agents
Water vapour has more kinetic energy.
Hope this helps :)
The process of science followed my initial ideas e because it involved experiments.
<h3>What is the process of science?</h3>
The process of science or the scientific method refers to the process which scientists follow in their discovery and explanation of natural phenomena.
The scientific method is given below:
- making an observation,
- develop a hypothesis,
- making a prediction,
- conducting an experiment
- analyzing the results
- propound a law
The process of science follows my initial ideas about the process of science because I always thought science involved experiments.
In conclusion, the process of science involves making hypothesis and conducting research.
