I am quite certain that it is B, a lipid!
A) Prevent (just imagine bushing a box up a ramp in your head)
Answer:
TRUE
Explanation:
Balance forces are usually defined as the two distinct force that acts on an object but in opposite directions. These two acting forces are equal in size or magnitude. When this type of force is applied on any object, it signifies that the object is stationary or it is moving at a constant speed and in the same direction.
This force is comprised of two most important properties namely the strength and direction. When any of the two forces is higher then it result in the motion of the object.
Thus, the above given statement is TRUE.
a) mg = * ω
b)ω =
c)14.7 the magnitude of the initial acceleration of the end B when the string is cut.
<h3>What is Acceleration?</h3>
Acceleration is the rate of change of the velocity of an object with respect to time.
Given
A rod of length 56.0 cm and mass 1.40 kg is suspended by two strings which are 42.0 cm long, one at each end of the rod.
When the string is cut rod rotates about other end.
Let's take momentum equation about that end:
mg* = Iω [I = ]
a) mg = * ω
Angular acceleration:
b)ω =
c)Acceleration of end B:
a = lω= =
a = 14.7 [g=9.8]

1. Answer:
It allows scientists to predict things about objects that are too small to see.
Explanation:
Atomic models are crucial to the scientific study of atoms. Through models, we represent atoms that we actually cannot see. Observation based study and testing is done through that model which helps us find flaws in one model so that a better model is made. In this way, it is helpful to study about atoms through atomic models.
2. Answer:
The correct step in a scientific experiment involving acids and bases is:
Using an indicator to measure the hydrogen ion concentration of a solution.
Explanation:
Two acids can never neutralize each other. The pH of a neutral solution is 7. Whereas pH of an acid is always less than 7.
Indicators are used to measure the pH of solutions. They give different colors in solutions with different solutions. So, in an experiment to check if the solution is acidic or basic, we need to measure its hydrogen ion concentration for which an indicator is used.
