Answer:
Angular acceleration = 5 rad /s ^2
Kinetic energy = 0.391 J
Work done = 0.391 J
P =6.25 W
Explanation:
The torque is given as moment of inertia × angular acceleration
angular acceleration = torque/ moment of inertia
= 10/2= 5 rad/ s^2
The kinetic energy is = 1/2 Iw^2
w = angular acceleration/time
=5/8= 0.625 rad /s
1/2 × 2× 0.625^2
=0.391 J
The work done is equal to the kinetic energy of the motor at this time
W= 0.391 J
The average power is = torque × angular speed
= 10× 0.625
P = 6.25 W
Explanation:
The density of an object can be calculated using the formula as follows :
Here,
m is mass of the object and V is its volume
The mass of an object can b measured in grams and its volume in cubic cm. So, the density of object is measured in g/cm³. Hence, out of given options the possible value of density of an object is 6 g/cm³.
Answer:
Form and genre are synonyms.
Explanation:
In literature, the form and genre of the work are two different yet related ideas. They are synonymous with each other, though not influenced by the other.
The form is the shape of the work, the type of work it is while the genre tells the contents of the work. The form can be as novels, essays, or poems whereas genre maybe horror, thriller, comedy, etc.
Thus, the correct answer is the third option.
Answer:
This force is called electromotive force, or EMF. Sometimes it is convenient to think of EMF as electrical pressure. In other words, it is the force that makes electrons move in a certain direction within a conductor.
