Elena held a rock weighing 1 N in her hand. The rock has no velocity. <br> KE________?
nignag [31]

KE = 0

<h3>Further explanation  </h3>

Energy is the ability to do work  

Energy because its motion is expressed as Kinetic energy (KE) which can be formulated as:  

\large{\boxed{\bold{KE=\frac{1}{2}mv^2}}}

So for two objects that have the same speed, the greater the mass of the object, the greater the kinetic energy  

The stone in hand is in a motionless state (at rest) so that its velocity (v) = 0, so it has no kinetic energy

But this stone can have <em>potential energy that is gained due to its height</em>

What is the difference between cell and cellmembrane​
lisov135 [29]

Answer:

So, a cell, in easiest terms, is "the building blocks of life". Without cells, humans, plants, animals, and anything else that has a cell would not be able to survive. Cells are extremely important to our bodies. Whereas a Cell Membrane is an organelle inside a cell. The Cell Membrane's job is to provide protection for the cell, as well as deciding which substances can enter and exit the cell.

I hope this helps!
