To find the vector that is equivalent to a vector of 12 Newtons at 75 degrees south of west, we need to determine the direction and magnitude of the equivalent vector.
The equivalent vector will have the same magnitude of 12 Newtons but a direction that is 180 degrees opposite to the given vector.
The given vector is 75 degrees south of west, which means it is pointing towards the south but slightly to the west.
Therefore, the direction of the equivalent vector will be 75 degrees north of east (opposite direction).
Among the given options:
a) 12 N at 15 degrees west of south - This is not the correct direction.
b) 12 N at 15 degrees south of east - This is not the correct direction.
c) 12 N at 15 degrees north of east - This is the correct direction.
d) 12 N at 15 degrees south of west - This is not the correct direction.
Therefore, the vector that is equivalent to the given vector is option c) 12 N at 15 degrees north of east.
the motion of the star
the temperature of the atmosphere of the star
all of the above
Answer:
all of the above
Explanation:
The spectrum of the star is is used to study its composition, motion and surface temperature. The absorbed or emitted wavelength indicates the elements present. The peak wavelength determines the surface temperature of the star using Wein's law. Peak wavelength is inversely proportional to temperature. The red-shift or blue shift indicates whether the star is moving away or towards us.
B. lunar breccias.
C. silicates.
D. highlands.
Jake drops a book out of a window from a height of 10 meters. The velocity does the book hit the ground is 14 m/s. hence option C is correct.
Velocity is defined as the pace at which an item changes position while moving in one direction, as seen from a certain point of view and as measured by a specific unit of time. Given that it has both a magnitude and a direction, velocity is a vector quantity. Velocity measures movement that begins in one location and moves to another location.
We are aware that V=final velocity and V2-U2=2.
U is the initial velocity, and A is the acceleration, and D is the distance, therefore V=14 m/s.
Thus, Jake drops a book out of a window from a height of 10 meters. The velocity does the book hit the ground is 14 m/s. hence option C is correct.
