If you have a vector which is 12 Newtons at 75 degrees south of west, what other vector is equivalent to this vector? a) 12 N at 15 degrees west of south b) 12 N at 15 degrees south of east c) 12 N at 15 degrees north of east d) 12 N at 15 degrees south of west

Answers

Answer 1
Answer:

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.

Which of the following can be determined by studying the spectrum of a star?the chemicals in the atmosphere of the star
the motion of the star
the temperature of the atmosphere of the star
all of the above

Answers

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.

The right answer for the question that is being asked and shown above is that: "all of the above." the following that can be determined by studying the spectrum of a star includes: the chemicals in the atmosphere of the star; the motion of the star; the temperature of the atmosphere of the star.

When an object falls through air, there is a drag with dimensions ml/t2 that depends on the ________. 1) size of the object 2) mass of the object 3) velocity of the object 4) density of the air

Answers

When an object falls through air, the drag with dimensions \(mL/t^2\) depends on the 1) size of the object, 2) velocity of the object, and 4) density of the air.

Your car is traveling at 70/mi/h (1000ft/s) your sneeze and your eyes close for 0.33 seconds how far did you travel during your sneeze?

Answers

If you're moving at 70 mi/hr, then you cover 33.88 feet in 0.33 sec. If you're moving at 1,000 ft/sec, then you cover 33 feet in 0.33 sec. 70 mph and 1,000 fps are not equivalent. 1,000 fps is about 682 mph, whereas 70 mph is about 103 fps.

Jake drops a book out of a window from a height of 10 meters. At what velocity does the book hit the ground? Answer choices: A: 7.0Meters/Second B: 10Meters/Second C: 14Meters/Second D: 28Meters/Second

Answers

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.  

What is velocity?

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.

#SPJ2
C is your answer. we know V^2-U^2=2 as where V=final velocity.
U is inital velocity
A= acc.
s= distence
a.t.q
v^2 -o^2 =(2*9.8*1o)
so, V=14 m/s
