Answer:
Mass of the box is 3.06 kg
Explanation:
Potential energy (that depends on gravity) is the type of energy which is stored that relies on the general position of different parts of a body. It is a property of a framework and not of an individual body or molecule; the framework made out of the Earth and the raised ball.
P.E = m.g.h Equation(1)
as we have to find the mass of the box then the formula for the mass will become
m=P.E/g(h) Equation(2)
as we know
P.E= 120J
h=4m
g=9.8m/s
g is the gravitational acceleration
putting values in the equation(2)
m = 120/9.8(4)
= 120/39.2
= 3.06 kg
mass of the box is 3.06 kg
Answer:
During the live television transmission of sports events, instant replay is often used to show again a passage of play which was especially important or remarkable, or which was unclear at first viewing.
Explanation:
Instant replay or action replay is a video reproduction of something that recently occurred which was both shot and broadcast live. The video, having already been shown live, is replayed in order for viewers to see again and analyze what had just taken place. Some sports allow officiating calls to be overturned after the review of a play. Instant replay is most commonly used in sports, but is also used in other fields of live TV. While the first near-instant replay system was developed and used in Canada, the first instant replay was developed and deployed in the United States.
Outside of live action sports, instant replay is used to cover large pageants or processions involving major dignitaries (e.g. monarchs, religious leaders such as the Catholic Pope, revolutionary leaders with mass appeal), political debate, legal proceedings (e.g. O.J. Simpson murder case), royal weddings, red carpet events at major award ceremonies (e.g. the Oscars), grandiose opening ceremonies (e.g. 2022 Winter Olympics opening ceremony), or live feeds to acts of terrorism currently in progress. Instant replay is used because the events are too large to cover from a single camera angle, events are too fast moving to catch all the nuance on the first viewing, the high points of the event are surrounded by much of a muchness, or punditry is supplied to punch the event up, such as analyzing the daring plunge of a plunging neckline to the last revealing millimeter.
In media studies, the timing and length of the replay clips as well as the selection of camera angles is a form of editorial content with a large impact on how the audience perceives the events covered.
There are 3 types of faults, strike-slip fault, normal fault and reverse fault. So choices a and d will no longer be considered. Now the difference between a normal fault and a reverse fault is in a normal fault the hanging wall moves downwards and in a reverse fault the hanging wall moves upwards.
So considering the two faults and their characteristics, the answer would be b. reverse fault.

Explanation:
Mars also has a thin atmosphere. Because of this it has potential to host humans and other organic life. That makes Mars the best choice for thriving colony off the earth. The moon has also been proposed as the first location for human colonization but it not known to have air or water.
Hope this helps!
Have an amazing day/night
