Albert bandura emphasized the idea of self-efficacy which is the belief one has in one’s own ability to succeed
What is self-efficacy?Self-efficacy is a person’s belief in their ability to succeed in a particular situation. Psychologist Albert Bandura described these beliefs as determinants of how people think, behave, and feel.
Self-efficacy can play a role in not only how you feel about yourself, but whether or not you successfully achieve your goals in life. The concept of self-efficacy is central to Albert Bandura’s social cognitive theory,
which emphasizes the role of observational learning, social experience, and reciprocal determinism in developing a personality.

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.

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
s = 4.8 m
Thus, the distance traveled by the box before it stops is 4.8 m.

100.0 grams of an isotope with a half-life of 36.0
hours is present at time zero. How much time will
have elapsed when 5.00 grams remains?
Answer:
155.6 hrs
Explanation:
5 = 100 (1/2)^n n = 4.32 half lives
4.32 * 36 = 155.6 hrs
The required, 155.58 hours will have elapsed when 5.00 grams of the isotope remains.
What is the half-life of the element?The half-life of the element is defined as the time span in which the element grows or decays half of its whole composition of growth and decay.
Here,
The decay of a radioactive substance can be modeled by the following equation,
[tex]N(t) = N_o (1/2)^{t/T}[/tex]
where N₀ is the initial quantity of the substance, N(t) is the quantity remaining after time t has elapsed, and T is the half-life of the substance.
In this problem, we are given,
N₀ = 100.0 g
N(t) = 5.00 g
T = 36.0 hours
We want to find the time t that has elapsed. Rearranging the equation above, we can solve for t,
t = T (log N₀ - log N(t)) / log 2
Substituting the given values, we get,
t = 36.0 hours x (log 100.0 - log 5.00 ) / log 2
t = 36.0 hours x 4.643 / 0.693
t = 155.58 hours
Therefore, approximately 155.58 hours will have elapsed when 5.00 grams of the isotope remains.

Due to the cylindrical symmetry of this problem, the induced electric field E⃗ (R,t) can depend only on the distance R from the z axis, where R is restricted to the region outside the iron rod. Find this field. Express E⃗ (R,t) in terms of quantities given in the introduction (and constants), using the unit vectors in the cylindrical coordinate system, θ^, r^, and k^
It is to be noted that the electric field that has been induced is (-B₁ A/2[tex]\pi[/tex]R)θ. This is obtained by using the vector units in the Cylindrical Coordinate System.
What are Cylindrical Coordinates?Cylindrical Coordinates are simply defined as a component of a coordinate system that is used to locate a location in space using its polar coordinates and vertical distance from the polar plane.
How is the induced field arrived at?The formula for Induced Electric Field is given as:
∫ E · dl = ∈
If we replace ∈ with -B₁A and 2[tex]\pi[/tex]R for dl then
∫ E · dl = -B₁A. Thus, we can state that
E∫ dl = -B₁A
Replacing or substituting 2[tex]\pi[/tex]R for ∫ dl ·E(2πR) = - B₁A
We can thus rearrange the equation to read:
E · E = ([tex]\frac{-B1A}{2\pi R}[/tex])θ
It is to be noted that the circumference of a circle is the integral of the length of the element. While θ, which in this case is the unit vector refers to the Cylindrical Coordinate and the direction of the electric field.

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
