<h2><u>S</u><u>o</u><u>l</u><u>u</u><u>t</u><u>i</u><u>o</u><u>n</u></h2>

<u>G</u><u>i</u><u>v</u><u>e</u><u>n</u>

  • u = 20 m/s
  • v = 30 m/s
  • t = 10 s

<u>F</u><u>i</u><u>n</u><u>d</u><u> </u>

  • a = ?

<h2><u>E</u><u>x</u><u>p</u><u>l</u><u>a</u><u>n</u><u>a</u><u>t</u><u>i</u><u>o</u><u>n</u></h2>

<u>U</u><u>s</u><u>i</u><u>n</u><u>g</u><u> </u><u>F</u><u>o</u><u>r</u><u>m</u><u>u</u><u>l</u><u>a</u>

★ v = u + at.

<u>K</u><u>e</u><u>e</u><u>p</u><u> </u><u>a</u><u>l</u><u>l</u><u> </u><u>v</u><u>a</u><u>l</u><u>u</u><u>e</u><u>s</u><u>.</u>

➡ 30 = 20 + a × 10

➡10a = 30 - 20

➡a = 10/10

➡a = 1 m/s².

Which equation best describes the law of conservation of momentum?
NeX [460]
The law of conservation of momentum<span> states that for two objects colliding in an isolated system, the total </span>momentum<span> before and after the collision is equal. Momentum should be conserved. Hope this answers the question. Have a nice day.</span>

By how much does the gravitational potential energy of a 54-kg pole vaulter change if her center of mass rises about 4.0 m durin
kodGreya [7K]
<span>the gravational potential energy of anything on the ground is zero. When calculating potential energy you take height in meters and multiply it by the mass of the object in kilograms and the acceleration of gravity to get a new unit called Joules. Any object at ground level has a potential energy of zero newtons becuase anything multiplied by zero is zero. An object with mass of 54 kg, 4 meters above the ground has a gravitatinal potential energy of 2116.8 Joules.</span>

How can you predict the action of the element
patriot [66]
Stark contrast to paths on energy surfaces or even mechanistic reactions, rule-based and inductive computational approaches to reaction prediction mostly consider only overall transformations. Overall transformations are general molecular graph rearrangements reflecting only the net change of several successive mechanistic reactions. For example, Figure 1 shows the overall transformation of an alkene interacting with hydrobromic acid to yield the alkyl bromide along with the two elementary reactions which compose the transformation.
