Laws are very rare in science and they focus on simple, clear, and undisputed facts. A scientific theory is an explanation that is based upon the evidence that is available. With the theory of evolution, and many other scientific theories, the Cell Theory has extremely strong evidence to support it.
Hope this helps!
Answer:
25J
Explanation:
Given parameters:
Mass of the dog = 10kg
Speed of the dog = 5m/s
Unknown:
The minimum energy required to stop the dog = ?
Solution:
The dog is moving with a kinetic energy and to stop the dog, an equal amount of kinetic energy generated must be applied to the dog.
To find the kinetic energy;
K.E =
m v²
m is the mass
v is the velocity
Now insert the parameters and solve;
K.E =
x 10 x 5 = 25J
Answer:
An atom with a closed shell of valence electrons (corresponding to an electron configuration s2p6) tends to be chemically inert. An atom with one or two valence electrons more than a closed shell is highly reactive, because the extra valence electrons are easily removed to form a positive ion.Explanation:
Option A looks like the best definition
Answer:
Explanation:
Intramolecular forces is a strong bond that helps to bond atoms together while intermolecular forces are weak bond that are present between molecules.
