Answer:
Explanation:
From the question we are told that:
Radius :
Work
Generally the equation for Work done is mathematically given by
Where
Therefore
The correct answer is
C. reduce the friction between its moving parts
In fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
Answer:
yi
Explanation:
Biosensors are used in the food industry to measure carbohydrates, alcohols and acids, for example, during quality control processes. The devices may also be used to check fermentation during the production of beer, yoghurt and soft drinks.
Answer:
It is directed downward. Its relative magnitude is a= qp*E/mp = 0.96*10⁸*E m/s².
Explanation:
Assuming gravitational force to be negligible, the only force acting on the proton once within the vacuum chamber, is the one due to the electric field.
As the proton is a positive charge, the electric force on it due to the field has the same direction than the field, as the direction of the field by convention, is the one that would take a positive test charge.
According to electric field definition, and to Newton's 2nd Law, we can find the acceleration of the proton as follows:
F = m*a = q*E ⇒ a= q*E / m = 1.6*10⁻¹⁹ C * E (N/C) / 1.67*10⁻²⁷ kg
⇒ a = 0.96* 10⁸ * E m/s²
