Describe the difference between continuous reinforcement and intermittent reinforcement.
Answer:
Continuous reinforcement delivers the reinforcement every single time the target behavior is delivered. (For example, if the target behavior for the dog is sitting when the owner says "sit", the treat (reinforcement) would be given whenever the dog follows the command). It follows a schedule-like reinforcement.
Intermittent reinforcement delivers the reinforcement to responses but are not consistent.

Carbon -14 is used to date a palm fossil that originally contained 0.24 grams of carbon -14. The half life is 5700 years. If the fossil is found to be 17,100 years old, how much carbon -14 does it contain now?
Please make sure to show all of your work/process so I can learn how to do it on my own!! thank you
Answer:
Exactly 0.03042 carbon-14 is remaining.
Roughly 0.03 Carbon-14 is remaining. (When/If Multiple Choice)
Explanation:
Not a physics question, this is chemistry, but I'll answer.
First, divide 17,000/5700 to find the t, or time.
t = 2.98245614 or 2.98.
If it originally contained .24 grams, and a half life means x/2,
you would use the formula x/2^p, with p being the number of half lives
(these variables are made up, you can use any you would like)
In 17,000 years, the palm fossil experienced 2.98 half lives.
Thus meaning, using our equation, we would find (.24)/2^2.98
This equals 0.030418784 carbon-14 remaining to be exact.
(For Multiple Choice, it may be required to round to For Multiple Choice, it may be required to round to 3, so .24/2/2/2 or .24/2=.12 then .06 then it equals : .03 Carbon-14)
Carbon -14 is used to date a palm fossil that originally contained 0.24 grams of carbon -14. The half life is 5700 years. If the fossil is found to be 17,100 years old then 0.0303 g of carbon -14 does it contain now.
What is radioactive decay ?The process by which an unstable atomic nucleus loses energy through radiation is known as radioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration). A radioactive substance is one that contains unstable nuclei. Alpha decay, beta decay (-decay), and gamma decay (-decay) are three of the most prevalent forms of decay, all of which entail the emission of one or more particles. The mechanism responsible for beta decay is the weak force, while the other two are regulated by electromagnetism and nuclear force. Electron capture is a fourth form of common decay in which an unstable nucleus grabs an inner electron from one of the electron shells.
According to decay formula,
N(t) = N₀ e^(-λt)
Given,
N₀ = 0.24g
t = 17100 years
λ = 0.693/T
Where T is half life.
λ = 0.693/5700 = 1.21 × 10⁻⁴
Putting all the values in the equation,
N(t) = 0.24g e^(-1.21 × 10⁻⁴ ×17,100)
N(t) = 0.0303 g

EXPERIMENT: MIXTURES
OBJECTIVES
Utilize a filter to separate a mixture of sand and water.
Summarize your findings.
Many tasks in chemistry involve separating mixtures. For example, crude oil by itself has very few uses, but many important substances are separated from crude oil. In this investigation we will attempt to separate sand from salt water, and salt from water. If you do not have access to sand, you can use small pebbles or BBs.
Before you begin the experiment, hypothesize whether or not you can separate sand from salt water using filter paper. After the experiment summarize your findings in a scientific report. Upload your report below in question 1.
These supplies are needed:
salt
water
sand
a measuring cup
a balance
filter paper
funnel
plastic spoon
two beakers or glasses
Measure 5 grams of salt and 10 grams of sand using the balance.
Mix together the salt and sand in a beaker or glass.
Add one half-cup of water to the salt-sand mixture.
Stir the mixture with the plastic spoon until all the salt is completely dissolved.
To filter the mixture fold the filter in half to form a semi-circle. Fold it again which creates the shape of a triangle. Place the filter paper in the funnel and open one layer of the filter paper and spread it out onto one side of the funnel, and the other three layers onto the other side of the funnel. You may want to wet the filter paper with water so that the filter paper lays flat against the sides of the funnel. Carefully pour the salt water -sand mixture into the funnel and drain the liquid into a beaker or glass.
Remove the filter paper from the funnel and lay it out flat to allow the sand to dry.
Answer:
I found out that you could separate the sand because the filterstion and all the materials uses their elements to filter it out
Findings say that one could separate the sand using the filtration and all the materials uses their elements to filter it out.
What is filtration?Filtration is the technique of segregating the components from a mixture.
In the given experiment, the filter is used to separate a mixture of sand and water.
This experiment can be successfully completed through the filtration process.
Thus, one could separate the sand using the filtration and all the materials uses their elements to filter it out.

A student slides a box across the floor to his friend. The mass of the box is 25 kg and the
coefficient of kinetic friction between the floor and the box is 0.52. If the initial velocity
of the box is 7.0 m/s, how far will the box slide before it stops?
The distance traveled by the box before stopping, when the student slides the box across the floor to his friend, at the given coefficient of kinetic friction is 4.8 m.
Acceleration of the boxThe acceleration of the box across the floor is determined by applying Newton's second law of motion.
∑F = ma
-Ff = ma
-μmg = ma
-μg = a
-(0.52 x 9.8) = a
- 5.1 m/s² = a
Distance traveled by the box before stoppingThe distance traveled by the box before it stops is calculated as follows;
v² = u² + 2as
where;
v is the final velocity of the box when it stops = 00 = (7)² + 2(-5.1)s
0 = 49 - 10.2s
10.2s = 49
s = 49/10.2
