A is wrong because something getting heated does not mean a chemical change.

B is wrong because its physical

C is wrong because its physical

D is correct because there is a new product.

btw the chemical formula for vinegar and baking soda is this I think:

CH3COOH + NaHCO3 ⇒ CH3COONa + CO2 + H2O.

inessss [21]

Answer:

The average angular acceleration is  \alpha =125.487 rad /s^2

Explanation:

From the question we are told that

  From the question we are told that

        The length of the bat is l = 0.85m  \

         The initial linear velocity is  u = 0 m/s

         The time is  t = 0.15s

         The velocity at t is  v = 16 m/s

  Generally average  angular acceleration is mathematically represented as

                \alpha  = \frac{w_f - w_o}{t}

        Where w_f is the finial angular velocity which is mathematically evaluated as  

            w_f = \frac{v}{l}

                  w_f = \frac{16}{0.85}

                        = 18.823 rad/s

 and w_o is the initial angular velocity which is zero since initial linear velocity is zero

               So

                         \alpha  = \frac{18.823 - 0}{0.15}

                               \alpha =125.487 rad /s^2

Which of the following means that an image is located behind a lens? A. +di B. -di C. -do D. +do
STatiana [176]
For a lens, the following sign convention is generally used:

- f (the focal length) is positive for a converging lens and negative for a diverging lens
- d_o (the distance of the object from the lens) is positive if the object is in front of the lens and negative if it is behind the lens
- d_i (distance of the image from the lens) is positive if the image is behind the lens (real image) and negative if the image is in front of the lens (virtual image)

Therefore, the correct option is 
<span>A. +di
</span>which mens that the image is real and located behind the lens.
