B) they would not be able to see anything outside the window.
C) lasers can not be transmitted through the vacuum of space.
D) the sound of the explosion would not be transmitted back to their ship.
Answer:
D. the sound of the explosion would not be transmitted back to their ship.
Explanation:
Sound is a type of mechanical wave so it needs a solid to move through. Since space is a vacuum, the Klingon crew would not be able to hear the explosion.
Answer:
Part a)
V = 18.16 V
Part b)
Part c)
P = 672 Watt
Part d)
V = 5.84 V
Part e)
Explanation:
Part a)
When battery is in charging mode
then the potential difference at the terminal of the cell is more than its EMF and it is given as
here we have
now we have
Part b)
Rate of energy dissipation inside the battery is the energy across internal resistance
so it is given as
Part c)
Rate of energy conversion into EMF is given as
Now battery is giving current to other circuit so now it is discharging
now we have
Part d)
Part e)
now the rate of energy dissipation is given as
The second law of thermodynamics states that whenever energy changes occur, DISORDER always increases.
The Second Law of Thermodynamics states that entropy, which represents the disorder or randomness in a system, always increases when energy changes occur. An example would be heat dispersing from a hot drink into the environment.
The Second Law of Thermodynamics states that whenever energy changes occur, entropy always increases. Entropy refers to the degree of disorder or randomness in a system. Thus, the law is essentially asserting that natural processes tend towards chaos or disorder. For example, if we consider a cup of hot coffee left on a table, with time, the heat (energy) from the coffee disperses into the surrounding environment, leading to an increase in entropy. This concept applies universally in closed systems, where energy cannot enter or leave.

b. particles that travel in a reverse direction to the direction of energy movement
c. particles that travel perpendicular to the direction of energy movement
d. particles that travel in an intersecting direction to the direction of energy movement
Answer:
a
Explanation:
i learned this last week in school.
The gravitational potential energy of the object falling from 18 m height is 36 J. Thus, its mass is 0.2 Kg.
Gravitational potential energy of an object is the energy generated by virtue of its position in a gravitational field. The magnitude of gravitational potential energy is directly proportional to the mass of the object , height from the surface and the acceleration due to gravity.
GPE = mgh
The height of the object falling = 18 m
Gravitational potential energy = 36 J
Acceleration due to gravity in earth = 9.8 m/s².
Mass of the object = GPE/ (gh)
= 36 J/ (18 m×9.8 m/s² )
= 0.20 Kg.
Therefore, the mass of the object is 0.20 Kg.
