Bandura's social learning theory, imitation, and observation are the two main ways that people pick up new skills. Bandura's theory encompasses more than just the notion that interaction with the environment leads directly to learning.
What Bandura children witnessed aggressive behavior?According to Bandura, hostility can also be learned indirectly through observational learning. According to the social learning theory, children learn through imitation.
An individual will internalize and replicate the aggressive behaviors of a role model in the future.
According to Bandura social learning theories, children pick up aggressive behaviors via watching others act aggressively and seeing how these actions are reinforced over time.
Therefore, it is false being punished were far more likely to be aggressive than children who did not.

In a football game the running back is running up the field. He starts from rest and runs 4 seconds with an acceleration of 1.3m/s. What is the magnitude of his displacement
We are given:
initial velocity (u) = 0 m/s
time (t) = 4 seconds
acceleration (a) = 1.3 m/s²
displacement (s) = x m
Solving for the displacement:
from the second equation of motion
s = ut + 1/2 at²
replacing the variables with the given values
x = (0)(4) + 1/2 (1.3)(4)(4)
x = 1/2 * 20.8

Which best describes the relationship between the terms “frequency,” “wavelength,” and “hertz”?
Wavelength is the number of frequencies, which is measured in hertz.
Frequency is the number of wavelengths, which is measured in hertz.
Wavelength is measured from frequency to hertz.
Frequency is measured from wavelength to hertz.
Answer:
Frequency is the number of wavelengths, which is measured in hertz.
Explanation:
I have my ways ;)
The relationship between the terms “frequency,” “wavelength,” and “hertz" is that frequency is the number of wavelengths, which is measured in hertz.
Relation between frequency and wavelength:The wavelength is described as the distance between two points on a wave having the same phase. It is also defined as the distance between two successive maxima or minima of the waveform.
The frequency of a wave is the measure of the number of wavelengths completed in one second and it is measured in Hertz (Hz).
The frequency is also the reciprocal of the time period of the wave, which is the time taken to complete one wavelength.
Therefore, frequency is the number of wavelengths, which is measured in hertz.

A net force of 10 N accelerates a mass of 5 kg with an acceleration of 2
m/s2. If the mass of the object is doubled, then the acceleration will now
be: (Remember Newton's 2nd Law: EF=ma)
4 m/s2
2 m/s2
O 1 m/s2
O 0.25 m/s2
Answer:
1 m/s²
Explanation:
The following data data were obtained from the question:
Net force (F) = 10 N
Initial mass (m1) = 5 Kg
Initial acceleration (a1) = 2 m/s²
Final mass (m2) = double the initial mass = 2 × 5 = 10 kg
Final acceleration (a2) =?
The final acceleration of the object can be obtained as follow:
Recall:
Force (F) = mass (m) × acceleration (a)
F = m × a
Keeping the force constant, we have
m1a1 = m2a2
With the above formula, we can obtain the final acceleration of the car as follow:
Initial mass (m1) = 5 Kg
Initial acceleration (a1) = 2 m/s²
Final mass (m2) = 10 kg
Final acceleration (a2) =?
m1a1 = m2a2
5 × 2 = 10 × a2
10 = 10 × a2
Divide both side by 10
a2 = 10 /10
a2 = 1 m/s²
Therefore, the final acceleration of the car will be 1 m/s²
A small sculpture made of gold ( rho gold =19320 kg/m^ 3 ) is believed to have a secret central cavity. The weight of the sculpture in air is 11.29 N. When it is submerged in water, the weight is 9.190 N. What is the volume of the secret cavity?
Answer:
1.1 x 10⁻⁵m³
Explanation:
Given parameters:
Weight in air = 11.29N
Weight in water = 9.190N
Density of gold = 19320kg/m³
Unknown:
Volume of the secret cavity = ?
Solution:
To solve this problem, we need to find the mass of the secret cavity.
Weight of the cavity = Weight of sculpture in air - Weight of sculpture in water
Weight of cavity = 11.29N - 9.190N = 2.1N
Weight = mass x acceleration due to gravity
Mass =[tex]\frac{2.1}{9.8}[/tex] = 0.2kg
So;
Volume of substance can be determined from the density.
Density = [tex]\frac{mass}{volume}[/tex]
Volume = [tex]\frac{mass}{density}[/tex]
Now insert the parameters and solve;
Volume = [tex]\frac{0.2}{19320}[/tex] = 1.1 x 10⁻⁵m³
On a given microscope, the numerical apertures of the condenser and low-power objective lenses are 1.25 and 0.25. You are supplied with a filter that selects a wavelength of 520nm.
Required:
a. What is the limit of resolution on this microscope?
b. Will you be able to distinguish 2 points that are 300nm apart as being separate, or will they blur into one?
Answer:
- colony: mass of single-type cells formed from single cell/small chain; pair or small cluster of cells; visible to naked eye
- colony forming unit: not visible to eye, original single cell or small chain/pair or small cluster of cells FROM WHICH colony forms
- Streaking plate: producing isolated colonies upon incubation using streak plate methods in agar
- Quadrant streak: used when sample is of high density
- Zigzag pattern: used when sample is of low density
a. The limit of resolution on this microscope is approximately 1254nm.
b. Two points that are 300nm apart will blur into one and cannot be distinguished as separate using this microscope.
The formula for the limit of resolution (d) is given by:
d = (0.61 × λ) / NA
where λ is the wavelength of light and NA is the numerical aperture.
a. To find the limit of resolution:
Given:
Wavelength of light (λ) = 520nm
Numerical aperture of the low-power objective lens (NA) = 0.25
Substituting these values into the formula, we have:
d = (0.61 × 520) / 0.25
d = 1254nm
Therefore, the limit of resolution on this microscope is approximately 1254nm.
b. To determine if two points 300nm apart can be distinguished:
Given:
Separation between the points (d) = 300nm
Since the separation between the points (300nm) is smaller than the limit of resolution (1254nm), the two points will blur into one and will not be distinguishable as separate entities.
In conclusion:
a. The limit of resolution on this microscope is approximately 1254nm.
b. Two points that are 300nm apart will blur into one and cannot be distinguished as separate using this microscope.

The acceleration due to gravity on Earth is 9.81 m/s² [down]. A hockey puck was launched from the ice with a velocity of 50.0 m/s [up]. Assuming no friction, determine the velocity of the puck at its maximum height.
Answer:
0 m/s.
Explanation:
When an object is shot up into the air the only force acting on it is gravity while neglecting wind. As the gravity is acting on the object it keeps decelerating till its velocity becomes 0 after which it can go no further. The maximum height of the object is at this point.
So, at its maximum height the velocity of the puck will be zero.

Answer:
19.62 m/s
34.335 m/s
1.75 m
Explanation:
v = Final velocity
u = Initial velocity = 0
a = g = Acceleration due to gravity = [tex]9.81\ \text{m/s}^2[/tex]
t = Time taken = 2 s
From the equations of linear motion we have
[tex]v=u+at\\\Rightarrow v=0+9.81\times 2\\\Rightarrow v=19.62\ \text{m/s}[/tex]
The speed of the object after 2 seconds is 19.62 m/s
t = 3.5 s
[tex]v=u+at\\\Rightarrow v=0+9.81\times 3.5\\\Rightarrow v=34.335\ \text{m/s}[/tex]
The velocity of the object when it strikes the ground is 34.335 m/s.
[tex]v^2-u^2=2as\\\Rightarrow s=\dfrac{v^2-u^2}{2a}\\\Rightarrow s=\dfrac{34.335-0}{2\times 9.81}\\\Rightarrow s=1.75\ \text{m}[/tex]
THe height from which the object was dropped is 1.75 m.

What is relative velocity?Velocity is a relative physical quantity that depends on the chosen frame of reference.
What is the mathematical formulation of relative velocity?Relative velocity=Vi-V'Where Vi is the velocity in inertial frame and V' is velocity with respect to the moving frame. Here, relative velocity=9 m/s and Vi = 7m/sSo, V'= Vi - relative velocity= 7m/s - 9 m/s = -2m/sThus, we can conclude that the robot fires the ball backward with a speed of 2 m/s.

Components of a Vector
A vector can be expressed in several forms, including the rectangular and the polar form.
The rectangular form uses the x-y coordinates of the vector, being the right and up directions considered as positive.
The polar form uses the magnitude r and the angle it forms with the positive x-direction.
Given the polar form (r,θ), we can calculate the rectangular coordinates as follows:
[tex]x=r\cos\theta\\[/tex]
[tex]y=r\sin\theta[/tex]
The soccer ball is kicked with an initial speed of v=12 m/s and an angle of 30 degrees. Thus the horizontal and vertical components are:
[tex]x=12~m/s\cos 30^\circ[/tex]
[tex]x=12~m/s\cdot 0.866[/tex]
x = 10.39 m/s
[tex]y=12~m/s\sin 30^\circ[/tex]
