Answer:
0.71ohms
Explanation:
AC and CB are in series hence the total resistance is 3+2=5ohms
AD and DB are in series hence the total resistance is 3+2=5ohms
These resistances are parallel to resistance AB
Let the equivalent resistance be R.
For resistances in parallel
Hence the total resistances are:
5//1//5
1/R =1/5 + 1/1 +1/5 = 1+5+1 /5 = 7/5
Hence the total resistance is R= 1/ 7/5 = 1×5/7= 5/7=0.71ohms
Answer:
Police powers are the fundamental ability of a government to enact laws to coerce its citizenry for the public good, although the term eludes an exact definition. The term does not directly relate to the common connotation of police as officers charged with maintaining public order, but rather to broad governmental regulatory power. Berman v. Parker, a 1954 U.S. Supreme Court case, stated that “public safety, public health, morality, peace and quiet, law and order. . . are some of the more conspicuous examples of the traditional application of the police power”; while recognizing that “an attempt to define police powers reach or trace its outer limits is fruitless.”
Answer:
a) The work done by a nonconservative force depends on the path taken. True.
c) A potential energy function can be specified for a conservative force. True
d) A conservative force permits a two-way conversion between kinetic and potential energies. True
Explanation:
Non-conservative forces dissipate. For example, friction or air resistance or drag.
A conservative force's property is that the work done in moving a particle does not depend on the path it has taken. For example, stored energy or potential energy. It permits two-way conversion between kinetic energy and potential energy. For example if a car goes up a hill, it converted kinetic energy in to potential energy. and if the car goes down the hill without hitting the gas pedal, it will roll down converting the potential energy in to kinetic energy.
b) A nonconservative force permits a two-way conversion between kinetic and potential energies. False
e) A potential energy function can be specified for a nonconservative force. False
f) The work done by a conservative force depends on the path taken. False
Answer:
Inertia
Explanation:
The state of motion of an object is defined by its velocity the speed with a direction. Thus, inertia could be redefined as follows: Inertia: tendency of an object to resist changes in its velocity - and ( in the absence of an unbalanced force ) will remain with a zero velocity.
