One of the difficulties in studying mechanics is that many common words are used with highly specific technical meanings,among t

hem velocity, acceleration, position, speed, and displacement. The series of questions in this problem is designed to getyou to try to think of these quantities like a physicist.Answer the questions in this problem using words from the following list: A. position B. direction C. displacement D. coordinates E. velocity F. acceleration G. distance H. magnitude I. vector J. scalar K. components
Part A Velocity differs from speed in that velocity indicates a particle's __________ of motion.Enter the letter from the list given in the problem introduction that best completes the sentence.
Part B Unlike speed, velocity is a __________ quantity.Enter the letter from the list given in the problem introduction that best completes the sentence.
Part C A vector has, by definition, both __________ and direction.Enter the letter from the list given in the problem introduction that best completes the sentence.
Part D Once you have selected a coordinate system, you can express a two-dimensional vector using a pair of quantities known collectively as __________.Enter the letter from the list given in the problem introduction that best completes the sentence. D Part E Speed differs from velocity in the same way that __________ differs from displacement.

What role did gravity played in the formation of the solar system​
hodyreva [135]

Gravity is the cause of . . .

-- star formation,

-- planet formation,

-- orbits.

So without gravity, there pretty much wouldn't be any solar or any system.

Vlada [557]

Answer:

Vmax=11.53 m/s

Explanation:

from conservation of energy

      E_A} =E_{B}

     Spring potential energy =potential energy due to elevation

   0.5*k*x²= mg(h_{B}-h_{A} )=mgh

   0.5*k*2.3²= 430*9.81*6

         k=9568.92 N/m

For safety reason

                                 k"=1.13 *k= 1.13*9568.92

                                    k"=10812.88 N/m

agsin from conservation of energy

      E_A} =E_{C}

    spring potential energy=change in kinetic energy

   0.5*k"*x²=0.5*m*V_{max}^{2}

      10812.88 *2.3²=430*V_{max}^{2}

           V_{max}=11.53 m/s

vlabodo [156]

Answer:

mu=12Tm^2

Explanation:

the magnetic moment mu of a single loop is given by:

\mu = I A B

where I is the current, B is the magnetic field and A is the area of the loop. By replacing we obtain:

\mu=(0.5A)(4m*2m)(3T)=12Tm^2

hope this helps!!
