Find the magnitude of this vector:

Physics
1 answer:
xeze [42]1 year ago
3 0

Answer: = 25. 5 m

Explanation:

  • 2-D vectors can be solved using the Pythagorean theorem:  
  • a^{2} +b^{2} =c^{2}
  • The hypotenuse, or longest side is not given and that is what must be solved for
  • Direction can be omitted as the question only asks for magnitude
  • Magnitude: is the distance or quantity in which an object moves during motion

Solve for C using Pythagorean theorem:

1. \sqrt{a^{2}+b^{2}  }=c

2.  \sqrt{22.2 m ^{2} +12.6m^{2} } =c

3. 25.52646 m= c

  • round to lowest number of significant digits  when dividing and multiplying
  • rounded to 3 significant digits

∴ Magnitude of the vector is 25.5 m

Help please
Anarel [89]

Answer:

1) D, 2) D, 3) B, 4) B, 5) C

Explanation:

You are asked to select the correct answer

1)  The conservation of energy is one of the most important principles of physics that allows solving countless problems in life.

the correct answer is D

2) when a body falls, the gravitational potential energy is transformed into kinetic energy and both are transformed into thermal energy

the correct answer is D

3) When the gravitational potential energy is maximum, the kinetic energy is minimum and when the kinetic energy is maximum, the gravitational energy is minimum.

Correct answer B

4) speed is defined by

         v = x / t

so the correct answer is B in the SI system

5) when we repeat a measurement several times, the random or statistical errors decrease, therefore the confidence of the measurement increases.

The correct answer is C

How long was a 60 W light bulb turned on if it used a total of 580 J of energy?
icang [17]
Here's the tool you need.  You can't answer the question without this:

           "1 watt"
means
           "1 joule of energy, generated, used, or moved, every second".

So      60 watts  =  60 joules per second

           Total energy generated,
            used, or moved                  = (power) x (time).

                                     580 joules  =  (60 watts) x (time)

Divide each side
by  (60 watts):              Time  =  (580 joules) / (60 joules/sec) 

                                               =  (9 and 2/3)  seconds  .
