Attribution theory is concerned with how ordinary people explain the causes of behavior and events. ... “Attribution theory deals with how the social perceiver uses the information to arrive at causal explanations for events. It examines what information is gathered and how it is combined to form a causal judgment”. Therefore it is like cause and effect, but just with our feelings and actions.

A mass on a spring oscillates with a frequency of 0.1 Hz. The mass is 10 kg. What is the spring constant of the spring?
Answer:
3.94784176044N/m
Explanation:
The period of a spring is found using the formula T=2π[tex]\sqrt{\frac{m}{k} }[/tex], where m is the mass and k is the spring constant.
The period can also be found using the formula T=[tex]\frac{1}{f}[/tex], where f is the frequency.
T=T
∴2π[tex]\sqrt{\frac{m}{k} }[/tex]=[tex]\frac{1}{f}[/tex]
2π[tex]\sqrt{10/k}[/tex]=1/0.1
[tex]\sqrt{10/k}[/tex]=10/2π
10/k=1.59154943092²
10/2.53302959106=k
k=3.94784176044N/m

20. If 4 X 1016 J of energy is released in a nuclear
reaction. Calculate the mass defect, Am (2 mark)
(A) 0.22kg (B) 0.44kg (C) 0.66kg (D) 0.88kg
I found this formula in an old book.
E = m · c²
It may be useful.
c = 3 x 10⁸ m/s
c² = 9 x 10¹⁶ m²/s²
4 x 10¹⁶ J = m · (9 x 10¹⁶ m²/s² )
m = (4 x 10¹⁶ J) / (9 x 10¹⁶ m²/s²)
m = 0.44 kg (choice-B)
Objects 1 and 2 attract each other with a electrostatic force of 36.0 units. If the charge of Object 1 is doubled, then the new electrostatic force will be units.
If the charge on the object is doubled then the new electrostatic force is 72 units.
What does the term "electrostatic force" mean?Non-contact forces, such as electrostatic forces, pull or push on objects without actually making contact with them. When certain materials are rubbed together, a phenomenon known as "charge" can be transferred from one surface to another. Uncharged items are pulled by charged objects, which in turn may push or pull against other charged ones.
Let q and Q represent the charges on objects 1 and 2, respectively.
Charge Q is separated from charge q by a distance r, and their electrostatic attraction is given by:
F = kqQ/r²
where k is Coulomb's constant
According to the question:
F = 36 units
⇒ kqQ/r² = 36 units
Now, the charge on object 2 is doubled, so it now acquires a 2Q charge.
So the new electrostatic force will be:
F' = kq(2Q)/r²
F' = 2kqQ/r²
F' = 2F = 2×36
F' = 72 units

Light from the Sun reflecting off the moon then reflects off particles in Earth’s atmosphere and scatters.
Answer:
Light from the Sun reflecting off the moon bends around particles in Earth's atmosphere and then spreads out.
Explanation:
edg 2021
The diffraction causes "Light from the Sun reflecting off the moon bends around particles in Earth’s atmosphere and then spreads out."
What is diffraction ?Diffraction is a phenomena in which light bends around the corners of obstacle in its path. This happens when the size of the obstacle is comparable to the wavelength of the light.
What is light?Light, often known as visible light, is electromagnetic radiation that falls within the region of the electromagnetic spectrum which the human eye can perceive.
What is moon?Moon can be considered as natural satellite. Moon does not have its own light. It reflects the sun-light which is received by us. The light after reflection from the surface of the moon passes through the atmosphere of Earth wherein it gets scattered by the molecules of the gases present in the earths atmosphere. This gives a fuzzy glow around a full moon.

The equation for centripetal force can be derived by substituting the equation for centripetal acceleration into Newton’s second law.
Please select the best answer from the choices provided
T
F
Answer:
True.
Explanation:
Newton's Second Law of Motion states that the acceleration of a physical object is directly proportional to the net force acting on the physical object and inversely proportional to its mass.
Mathematically, it is given by the formula;
Force = mass * acceleration
[tex] F = ma[/tex]
Centripetal acceleration is given by the formula;
[tex] Acceleration, a = \frac {v^{2}}{r}[/tex]
Where;
v is the velocity.
r is the radius.
The equation for centripetal force can be derived by substituting the equation for centripetal acceleration into Newton’s second law.
Let centripetal force be Fc
Fc = ma
Substituting the value of "a" into the above formula;
[tex] Fc = m \frac {v^{2}}{r} [/tex]
[tex] Fc = \frac {mv^{2}}{r} [/tex]

Explanation:
Fgrav = m • g = 14.7 N (g is 9.8 m/s/s)
a = v2 / R = (4 • Fgrav)/1 = 16 m/s/s
Fnet = m • a = 1.5 kg •16 m/s/s = 24 N, down
Fnet = Fgrav + Ftens, so
Ftens = Fnet - Fgrav
Ftens = 24 N - 14.7 N = 9.3 N

Which term describes the transfer of energy from a hot object to a cooler
one?
A. Pressure
B. Density
C. Temperature
D. Heat
Answer:
D
Explanation:
heat is an energy that transfers from a hot body to cold body
D. Heat
What is heat?Heat is the transfer of kinetic energy from one medium or object to another, or from an energy source to a medium or object.
Such energy transfer can occur in three ways: radiation, conduction, and convection.
As heat is a form of energy, and therefore the SI unit of heat is also joules (J) which are defined as the amount of energy needed to raise the temperature of a given mass by one degree.
Heat is the transfer of energy from a warmer object to a cooler object.
For example, a lighted match (higher temperature object) will transfer heat to a large pan filled with lukewarm water (lower temperature object).
Therefore,
The term describes the transfer of energy from a hot object to a cooler one is Heat.
