Answer:
At low pressure- 
At high pressure- 
Explanation:
Initial speed, 
Final speed, 
Net horizontal force due to rolling friction 
mg where m is mass, g is acceleration due to gravity, 
is coefficient of rolling friction
From kinematic relation, 
For each tire,
Making the subject
Under low pressure of 40 Psi, d=18 m
Therefore,
At a pressure of 105 Psi, d=93.7
Therefore,
Explanation:
There are many ways to achieve a healthier lifestyle and increase fitness. Healthy eating and constant exercise are essential for maintaining good physical and mental health. Through effective nutrition the human body is able to function better, there is an increase in disposition, improvement in immunity, improvement in blood rates, etc. Physical exercise, on the other hand, assists in strengthening muscles, controlling blood pressure, preventing cardiovascular disease, greater satisfaction, less stress, etc.
Some simple examples that can assist in improving health and fitness are:
- Reduction of processed foods, sugars and soft drinks.
- Increased fiber intake
- Daily walks of at least 30 minutes
- Increased water consumption
- Increased consumption of fruits and vegetables
- Incorporate meditation and yoga practices
The student's claim did not follow the scientific method of discovery, hence, it is an opinion not a scientific claim.
<h3>What is the scientific method?</h3>
The scientific method is a procedure employed by scientific towards understanding the world around them as well giving explanation for phenomena in the natural world.
The scientific method involves:
- observations
- asking questions
- putting forward a hypothesis
- testing the hypothesis through experiments
- analyzing results of the experiments and drawing conclusions
- establishing a theory.
Since the student in question just put forward an opinion without testing it out using the scientific method, the statement is not a scientific claim.

Answer:
Explanation:
The Coulomb's law states that the magnitude of the electrostatic force between two charges is directly proportional to the product of the magnitudes of charges and inversely proportional to the square of the distance between them:
In this case, we have 
:
<span>The egg doesn't break when it hits the sheet because the impact time is longer. Momentum means the egg is slowed rather than coming to an abrubt halt. The softer the object that the egg hits, the longer the time it takes to break. A sheet is so soft that the force is never high enough for the egg to break.</span>
