James had a fixation on how to best preserve fresh cut flowers. He tried various methods: adding bleach to the water, using filt

ered water, adding an aspirin tablet to the water, using a combination of sugar and water, using cold water, and using hot water. Over the course of his study, he came to the conclusion that while bleach changed the color of the plant, it did allow for the plant to last longer than the other changes. Based on this study, the dependent variable is: 1. Type of plant 2. Life of the cut plant 3. Color of the plant 4. Changes to the water

Jenny was applying her makeup when she drove into the student parking lot last Friday morning . Unaware that Cheryl was stopped
Akimi4 [234]

Answer: F = 102141N

Explanation: <em><u>Newton's 2nd Law</u></em> states that a force can change the motion of a body. The relation is given by

F = m.a

whose units are:

[F] = N

[m] = kg

[a] = m/s²

Jenny's car, at the moment of the break, had acceleration:

a=\frac{\Delta v}{\Delta t}

a=\frac{11}{0.14}

a = 78.57 m/s²

Then, Force is

F = 1300*78.57

F = 102141 N

<u>Jenny's car experienced a force of </u><u>magnitude 102141N.</u>

11Alexandr11 [23.1K]
Given a = 10 cm/s²
          u = 0 cm/s
          v = 50 cm/s
we know that 
         v²=u²+2aS
        2500=2×10×S
        2500÷20 = S
        S= 125 cm

The difference in outcome between the potential energy in a marshmallow burned over a campfire on the end of a stick and in one
Lapatulllka [165]

Answer:

How fast and efficient the energy is released.

Explanation:

Before burning the marshmallow energy is stored in it in the form of chemical bond energy or chemical potential energy. So upon burning this energy is released. So there will be a difference in energy release from a burned marshmallow and the one we eat straight from package.
