<h3><u>Answer;</u></h3>
Centripetal acceleration = 0.931 m/s²
Centripetal force = = 1.234 × 10^-4 Newtons
<h3><u>Explanation;</u></h3>
Centripetal acceleration is given by the formula v²/r, where r is the radius of the circular path and v is the velocity of a body;
Centripetal acc = 3.2²/11
= 0.931 m/s²
Centripetal force is a force that acts on an object or a body in circular path and is directed towards the center of the circular path.
Centripetal force is given by the formula;
mv²/r ; where m is the mass of the body, r is the radius of the circular path and v is the velocity of a body;
mass = 33 mg or 1.33 × 10^-6 kg, velocity = 3.20 m/s and r = 11 m
Therefore;
Centripetal force = (1.33 ×10^-6 × 3.1²)/ 11
= 1.234 × 10^-4 Newtons
Density is defined as mass per unit volume. It has the SI unit kg m-3 or Kg/m-3 and is an absolute quantity. Specific gravity is the ratio of a material's density with that of water at 4 °C (where it is most dense and is taken to have the value 999.974 kg·m-3). It is therefore a relative quantity with no units.
hi <3
i believe the answer would be D, as when the temperature increases the particles have more energy and can overcome the activation energy more rapidly.
hope this helps :)
