A man pushed the box with a force of 20 N. The mass of the box doubled, but he still pushed with a force of 20 N.
Which option describes how the acceleration of the box after the mass was doubled?
a) The acceleration is 2x the original acceleration
b) Acceleration is 4x the original acceleration
c) Acceleration is 1/2x the original acceleration
d) Acceleration is 1/4x the original acceleration
Answer:
Option (c) Acceleration is 1/2x the original acceleration
Explanation:
To know the the correct answer to the question, we shall determine the acceleration of the box in each case.
Case 1:
Mass (m) = m
Force (F) = 20 N
Acceleration 1 (a₁) =?
F = ma₁
20 = m × a₁
Divide both side by m
a₁ = 20 / m
Case 2:
Mass (m) = 2m
Force (F) = 20 N
Acceleration 2 (a₂) =?
F = ma₂
20 = 2m × a₂
Divide both side by 2m
a₂ = 20 / 2m
a₂ = 10 / m
Finally, we shall determine the acceleration of the box after the mass was doubled. This can be obtained as illustrated below:
Acceleration 1 (a₁) = 20 / m
Acceleration 2 (a₂) = 10 / m
a₂ : a₁ = 10 / m : 20 / m
a₂ / a₁ = 10 / m ÷ 20 / m
a₂ / a₁ = (10 / m) × (m / 20)
a₂ / a₁ = ½
Cross multiply
a₂ = ½a₁
Thus, the acceleration of the box after the mass was doubled is ½ times the original acceleration.

Reflection of light (and other forms of electromagnetic radiation) occurs when the waves encounter a surface or other boundary that does not absorb the energy of the radiation and bounces the waves away from the surface. The simplest example of visible light reflection is the surface of a smooth pool of water, where incident light is reflected in an orderly manner to produce a clear image of the scenery surrounding the pool. Throw a rock into the pool (see Figure 1), and the water is perturbed to form waves, which disrupt the reflection by scattering the reflected light rays in all directions.
Some of the earliest accounts of light reflection originate from the ancient Greek mathematician Euclid, who conducted a series of experiments around 300 BC, and appears to have had a good understanding of how light is reflected. However, it wasn't until a millennium and a half later that the Arab scientist Alhazen proposed a law describing exactly what happens to a light ray when it strikes a smooth surface and then bounces off into space.
In this activity you will be working as an engineer that is working to modify different kinds of digital cameras and to study the effect of changing incident angle on the reflected angle.

Which statement accurately describes viscosity?
A. A liquid with larger molecules resists movement more than a liquid with smaller molecules does.
B. A material slows or completely blocks the flow of electrons through it.
C. A material with relatively weak bonds between its particles can be shaped into a thin sheet.
D. Attractive forces between molecules at the surface cause a liquid to resist spreading out.
The statement that accurately describes viscosity is option D: Attractive forces between molecules at the surface cause a liquid to resist spreading out. Option D
Viscosity is a measure of a fluid's resistance to flow. It quantifies how easily a fluid can be deformed or how readily it flows. In liquids, viscosity arises from the cohesive forces between molecules.
When molecules in a liquid are attracted to each other, they tend to stick together and resist movement. At the surface of the liquid, there is a greater degree of attractive forces between the molecules since they have fewer neighboring molecules to interact with.
This surface tension creates a resistance to the spreading out of the liquid and causes it to exhibit a more rounded or droplet-like shape.
The attractive forces between molecules at the surface of a liquid contribute to the cohesive forces within the liquid as a whole, resulting in a higher viscosity.
The stronger the attractive forces between the molecules, the higher the viscosity of the liquid. For example, honey has a higher viscosity compared to water because the molecules in honey have stronger attractive forces, making it flow more slowly.
Option A is not an accurate description of viscosity. Viscosity is not solely determined by the size of the molecules in a liquid but rather by the strength of the attractive forces between the molecules.
Option B describes electrical conductivity, not viscosity. It refers to a material's ability to slow down or impede the flow of electrons.
Option C describes the property of malleability, not viscosity. It refers to a material's ability to be shaped into a thin sheet without breaking.
Therefore, option D accurately describes viscosity by highlighting the role of attractive forces between molecules at the surface of a liquid in resisting the spreading out of the liquid

To what temperature will a 50.0 g piece of glass raise if it absorbs 5275 joules of heat and its specific heat capacity is 0.50 J/g°C? The initial temperature of the glass is 20.0°C.
Answer:
Final temperature, T2 = 131895°C
Explanation:
Given the following data;
Mass = 50g
Initial temperature = 20°C
Quantity of heat = 5275J
Specific heat capacity = 0.50 J/g°C
To find the final temperature;
Heat capacity is given by the formula;
[tex] Q = mcdt[/tex]
Where;
Q represents the heat capacity or quantity of heat.
m represents the mass of an object.
c represents the specific heat capacity of water.
dt represents the change in temperature.
Making dt the subject of formula, we have;
[tex] dt = \frac {Q}{mc} [/tex]
Substituting into the equation, we have;
[tex] dt = \frac {5275}{50*0.50} [/tex]
[tex] dt = \frac {5275}{25} [/tex]
dt = 131875°C
Now, the final temperature T2 is;
But, dt = T2 - T1
T2 = dt + T1
T2 = 131875 + 20
T2 = 131895°C
The final temperature when a glass piece absorbs heat 5275 joules will be T2= 231 C
What is heat capacity?
The heat capacity is defined as the amount of heat any material can absorb when the temperature is changed to unit quantity.
Given the following data;
Mass = 50g
Initial temperature = 20°C
Quantity of heat = 5275J
Specific heat capacity = 0.50 J/g°C
To find the final temperature;
Heat capacity is given by the formula;
[tex]Q= mc(T_2-T_1)[/tex]
Where;
Q = represents the heat capacity or quantity of heat.
M= represents the mass of an object.
C= represents the specific heat capacity
T1= initial temperature
T2 = Final temperature
Substituting into the equation, we have;
[tex]Q=mc(T_2-T_1)[/tex]
[tex](T_2-T_1)=\dfrac{Q}{mc}[/tex]
[tex](T_2-T_1)=\dfrac{5275}{50\times 0.50}[/tex]
[tex]T_2=211+T_1[/tex]
[tex]T_2=211+20=231 ^oc[/tex]
Thus the final temperature when a glass piece absorbs heat 5275 joules will be T2= 231 C
