Answer:
The atoms of the system with higher temperature will gain the heat energy and the vibration of these atoms will increase. The atoms or molecules on the system with lower temperature have lower temperature and are not vibrating. ... So, we can say that heat always flows from higher temperature to a lower temperature.
Answer:
The angular momentum of the solid sphere is 0.667 kgm²/s
Explanation:
Given;
radius of the solid sphere, r = 0.15 m
mass of the sphere, m = 13 kg
angular speed of the sphere, ω = 5.70 rad/s
The angular momentum of the solid sphere is given;
L = Iω
Where;
I is the moment of inertia of the solid sphere
ω is the angular speed of the solid sphere
The moment of inertia of solid sphere is given by;
I = ²/₅mr²
I = ²/₅ x (13 x 0.15²)
I = 0.117 kg.m²
The angular momentum of the solid sphere is calculated as;
L = Iω
L = 0.117 x 5.7
L = 0.667 kgm²/s
Therefore, the angular momentum of the solid sphere is 0.667 kgm²/s

Concept being tested: Waves and types of waves
To answer the question we need to define both electromagnetic waves and mechanical waves.
- Waves can be classified as either electromagnetic waves and mechanical waves based on whether they require a material medium for transmission or not.
- Electromagnetic waves do not require a material medium for transmission and can travel through a vacuum.
- Mechanical waves, on the other hand, are waves that require a material medium for transmission.
What are examples of electromagnetic waves and mechanical waves?
- Examples of electromagnetic waves include gamma rays, radio waves, visible light, etc.
- Examples of mechanical waves include sound waves and water waves.
Therefore, the answer to our question is;
- Electromagnetic waves are not mechanical waves, which means they can travel in a vacuum.
Answer:
The statement is not correct.
Reason:
If two objects have the same mass, their respective densities determine their volumes.
By definition,
density = mass/volume.
or volume = mass/density.
Therefore if two objects have the same mass, the mode dense object (with higher density) will occupy less volume than the other object.
