Answer: 735 N
Explanation:
Weight
is a measure of the gravitational force acting on an object and is directly proportional to the product of the mass
of the body by the acceleration of gravity
:
In the case of our planet Earth, the acceleration due gravity is
. So for a man whose mass is
, his weight is:
Your answer is C. hope this helped! :)
Answer:
Upright and smaller than the object
Explanation:
Diverging lens as the name suggests that the rays diverge after the refraction and do not meet in reality. A concave lens is called diverging lens. When there is refraction of light through a concave lens then the light bends away from the principal axis and hence never meet in reality but on tracing the rays backwards the rays appear to meet leading to the formation of a virtual image, which is erect and smaller than the object for an object placed at the focus of the lens.
Similar image is formed for any case when the object is between optical center and infinity.
The changes in internal energy of the system <u>75.1 J.</u>
The internal energy of a thermodynamic system is the total energy contained in it. It is the energy required to create or prepare a system in a given internal state and includes contributions of potential energy and internal kinetic energy.
Calculation:
Internal energy = 162.4 j - work done
= 162.4 j - 87.3 j
=<u> 75.1 J</u>
<u />
Internal energy, in thermodynamics, is the property or state function that defines the energy of matter in the absence of capillary action or external electric, magnetic, or other fields.
Internal energy is the microscopic energy contained in the matter given by the random and disordered kinetic energy of the molecules. It also includes the potential energy between these molecules and the nuclear energy contained in the atoms of these molecules.

Answer:
emf=-0.035V
Explanation:
this problem can be solved with the Lenz's law:

where PhiB is the magnetic flux. In this case we have

due to the magnetic field is constant. A is the area of the circular loop. Hence

Finally
