Answer:

<h2>411.86 J</h2>

Explanation:

The kinetic energy of an object can be found by using the formula

k =  \frac{1}{2} m {v}^{2}  \\

m is the mass

v is the velocity

From the question we have

k =  \frac{1}{2}  \times 55  \times  {3.87}^{2}  \\  = 27.5 \times 14.9769 \\  = 411.86475

We have the final answer as

<h3>411.86 J</h3>

Hope this helps you

How does removing trees affect nitrogen cycling in a forest ecosystem? A. After clearcutting, more soil nitrogen was exported vi
mina [271]

Answer:

B. After clearcutting, plant uptake stopped and nitrogen accumulated in the soil.

Explanation: Clear cutting leaves the soil bare and allows for direct penetration of sunlight this increases the soil temperature which favors the activity of soil microrganism. This microrganism activity increase the production of ammonium and nitrate hence the increase in soil Nitrogen level. Clearcutting then allows for accumulation of Nitrogen produce due to removal of plant or forest tree that could use up the Nitrogen produced.

Hiiiiiiii please help me please &gt;-&lt; 35 points!
Travka [436]

Answer:

I just answered this same question for my Biology class hope this helps :)

Explanation:

A hydrogen bond is when positive and negative hydrogen forms together; this explains why cohesion sticks molecules together . Because of cohesion, the water molecules stick together and form a surface; this property is responsible for surface tension. Adhesion is the ability for water to stick to other substances; this helps with capillary action. Hydrogen bonding also explains why water's boiling point is higher than some liquid . With this, water has a high specific heat; this is because the water takes a lot of energy to raise (or lower) the temperature. Once again, hydrogen bonding is essential to another property. This property causes water to expand and to have a low density when frozen.
