temperature of 27°C. Which statement explains why the bar of aluminum has
a lower temperature?
Answer:the particles that make up the aluminum bar are moving more slowly
Explanation:just did it on
A bar of gold has a temperature of 31°C, and a bar of aluminum has a
temperature of 27°C. Because the particles that make up the aluminum bar are moving more slowly.
What is Temperature ?Temperature is a physical quantity which measures hotness and coldness of a body. Temperature measures the degree of vibration of molecule in a body. Temperature is measured in centigrade (°C), Fahrenheit (°F) and Kelvin (K) in which Kelvin (K) is a SI unit of temperature.
Absolute scale of temperature means Kelvin scale of temperature. relation between Kelvin(K) and centigrade (°C), °C= K - 273.15 from equation, 273.15 K means 0 °C, which is freezing point of water (ice). when we give temperature to the body, its molecule or atom absorbs thermal energy and vibrate about their mean position.
Amplitude of vibration get increases as we go on increasing temperature and for higher temperature force of attraction between molecules gets weaker. Hence for higher temperature, due to weaken the force of attraction between molecule, solid goes into liquid state. and further increase in temperature liquid goes into gaseous state.

Answer:
The horizontal and vertical displacement is 128.02 m and 68.07 m respectively.
Explanation:
Displacement, d = 145 m
The top of a building at an angle of 28 degrees below the horizontal
We need to find the horizontal and vertical displacement.
For horizontal displacement,
[tex]D_x=d\cos\theta\\\\D_x=145\times \cos(28)\\\\D_x=128.02\ m[/tex]
For vertical displacement,
[tex]D_y=d\sin\theta\\\\D_y=145\times \sin(28)\\\\D_y=68.07\ m[/tex]
So, the horizontal and vertical displacement is 128.02 m and 68.07 m respectively.

7. A mass m1 of 250 g is on a table connected to a massless pulley, as shown. The coefficient of friction between m1 and the table is 0.228. What is the maximum value of m2 before m1 starts sliding across the table?
Answer:
The minimum mass of m2 before m1 starts sliding across the table is 57 grams
Explanation:
The given mass on the table, m1 = 250 g
The coefficient of friction between the table and the mass, m1, μ = 0.228
Therefore, the friction force, F[tex]_F[/tex] between the mass m1 and the table is given as follows;
F[tex]_F[/tex] = W₁ × μ
Where;
W₁ = The weight of m1 = Mass of m1 × Acceleration due to gravity
W₁ = 250 g × 9.81 m/s² = 0.25 kg × 9.81 m/s² = 2.4525 N
W₁ = 2.4525 N
Which gives;
F[tex]_F[/tex] = 2.4525 N × 0.228 = 0.55917 N
F[tex]_F[/tex] = 0.55917 N
By equilibrium of forces, the weight, W₂, of the mass m2 at which the mass m1 starts sliding is equal to the frictional force F[tex]_F[/tex] of m1 or 0.55917 N
Therefore, for slipping to occur, we have;
W₂ = 0.55917 N
However, W₂ = Mass of m2 × Acceleration due to gravity
∴ W₂ = 0.55917 N = m2 × 9.81 m/s²
0.55917 N = m2 × 9.81 m/s²
m2 = 0.55917 N/(9.81 m/s²) = 0.057 kg = 57 grams
The minimum mass of m2 before m1 starts sliding across the table is 57 grams.

They prevent objects from moving in a circular motion.
Answer:
A: They change the motion of objects
Explanation:
Gravity force that attracts a body toward the center of the earth, or toward any other physical body having mass.
Inertia: is a property of matter by which it continues in its existing uniform motion in a straight line, unless that state is changed by an external force.
They change the motion of objects. This statement explains how gravity and inertia work together, Hence option A is correct.
What is Gravity ?Gravity is a basic interaction in physics that produces mutual attraction between all objects having mass or energy. By far the weakest of the four fundamental interactions, gravity is approximately 1038 times weaker than the strong interaction, 1036 times weaker than the electromagnetic force, and 1029 times weaker than the weak interaction. As a result, it has no effect at the level of subatomic particles. Gravity, on the other hand, is the most significant interaction between things on the macroscopic scale, determining the motion of planets, stars, galaxies, and even light.
Hence option A is correct.

which of these is a logical hypothesis regarding mass and period
Answer:
An increase in the mass on the string will cause an increase in the period.
Explanation:
We'll begin by writing an expression showing the relationship between the period and mass. This is shown below:
T = 2π√(m/K)
Where:
T is the period of oscillation.
m is the mass of the object.
K is the spring constant.
T = 2π√(m/K)
From the above formula:
The period (T) is directly proportional to the square root of mass (m) and inversely proportional to the square root of the spring constant (K). This implies that an increase in the mass of the object on the spring will result in an increase in the period of oscillation and a decrease in the mass of the object will also decrease the period of oscillation.
