Answer

Explanation:

Simple arithmetic cannot be used if two or more vectors are not along the same direction. Vectors can be added when two vectors are in the same direction but for the subtraction of vectors, if the vectors are not in the same direction you then subtract.

scoundrel [369]

The effective mass of the system is 12 kg.

<u>Explanation:</u>

  • The effective mass of the system is given by the expression,

                    = mₓ + 1/2 m₁ + 2/5 m₂

  • In the above equations the subscript x denotes block B and the subscript 2 denotes the mass of the solid sphere and the subscript 1 denotes the pulley.
  • Expressing the above functions with the data given below. we have,

           = 6 kg + 1/2 (4 kg) + 2/5 (10 kg)

           =  12 kg.

with the findings above we can conclude that the effective mass of the system is 12 kg

stealth61 [152]
<span>The answer is C. temperature, light level, species of bacteria. All three variables are considerations regarding the reproduction rate of the bacteria. The other three answer choices can be eliminated easily because they each contain at least one irrelevant variable. In particular, all three contain a variable that makes reference to Jack's personal characteristics. These do not have any impact on the experiment and readily stand out to disqualify the entire answer choice.</span>

Fudgin [204]

Answer:

The average velocity would be 217 m/s.

Explanation:

Average velocity is calculated by v(avg)=final velocity+inital velocity over 2

Displacement is the change in position (vector)

Velocity is calculated by s= d/t distance/time
