Explanation:

The combination of two waves is "mechanical waves". The correct option is A.
What is a mechanical wave?A mechanical wave is a type of wave that requires a medium to travel through. In a mechanical wave, energy is transferred through the motion of particles in the medium, rather than the transfer of matter. Examples of mechanical waves include sound waves, water waves, and seismic waves.
In a mechanical wave, energy is initially added to a small region of the medium, which creates a disturbance that propagates outward as a wave. As the wave travels, particles in the medium oscillate back and forth around their equilibrium positions, transferring energy to neighboring particles. The wave continues to travel until it encounters a boundary, where it may be absorbed, transmitted, or reflected.
Mechanical waves can be classified as transverse waves or longitudinal waves, depending on the direction of particle motion relative to the direction of wave propagation. In a transverse wave, particle motion is perpendicular to the direction of wave propagation, while in a longitudinal wave, particle motion is parallel to the direction of wave propagation.
Mechanical waves are an important aspect of many natural phenomena and technological applications. They play a crucial role in fields such as acoustics, optics, and seismology, and have applications ranging from medical imaging to telecommunications.
Here in the Question,
A combination of two waves can be any type of wave, but it is most commonly a type of mechanical wave. Mechanical waves are waves that require a medium to travel through, such as sound waves or water waves.
The other three types of waves mentioned - longitudinal waves, surface waves, and transverse waves - are all specific types of mechanical waves.
Longitudinal waves are waves in which the particles of the medium vibrate back and forth parallel to the direction of wave propagation. Examples include sound waves and seismic waves.
Transverse waves are waves in which the particles of the medium vibrate perpendicular to the direction of wave propagation. Examples include light waves and electromagnetic waves.
Surface waves are waves that occur at the interface between two different media, such as the interface between air and water. Examples include ocean waves and seismic waves.
Therefore, the most appropriate answer to the question would be "mechanical waves".

A student adds a tablespoon of sugar to a glass containing
tea and ice cubes. The mixture is then stirred until all the
sugar dissolves.
Which observation is a clue that the student's final mixture is heterogeneous?
A. Some ice cubes are floating in the tea.
B. Some water droplets form on the outside of the glass.
C. The mixture looks the same throughout.
D. The sugar crystals are no longer visible in the tea.
Answer:
[tex]\huge\boxed{\sf Option \ A}[/tex]
Explanation:
When we stir the solution such that it forms a mixture and the sugar is completely dissolved, we still find some ice cubes floating in the tea which shows that it is a heterogeneous mixture.

An airplane accelerates with a constant rate of 3.0 m/s2 starting at a velocity of 21 m/s. If the distance traveled during this acceleration was 535 m, what is the final velocity?
Answer:
60.42 m/s.
Explanation:
This problem can be solved using equation of motion
[tex]V^2 = u^2 + 2as[/tex]
where v is the final velocity
u is the initial velocity
a is the acceleration
s is the distance moved by the body to reach final velocity v from initial velocity u.
___________________________________________________
given
u = 21m/s
a = 3.0 m/s2
s = 535 m
v, the final velocity we have to find
using the equation of motion
[tex]V^2 = u^2 + 2as\\V^2 = 21^2 + 2*3*535\\V^2 = 441 + 3210 = 3651\\\sqrt{v^2} = \sqrt{3651} \\v = 60.42[/tex]
Thus, the final velocity of airplane is 60.42 m/s.
The final velocity is 60.42 m/s
The parameters given in the question are;
initial velocity(u)= 21 m/s
acceleration(a)= 3.0 m/s²
distance(s)= 535 meters
final velocity(v)= ?
The final velocity can be calculated as follows
v²= u² +2as
v²= 21² + 2(3)(535)
v²= 441 + 3210
v²= 3651
v= √3651
v= 60.42
Hence the final velocity is 60.42 m/s

The bicep muscle has an attachment point at the shoulder and one in the upper forearm. Look at these images of the bones of the arm. Imagine that the point of the arrow is where the force of the biceps muscle is applied to the bone. 4 images of the bones of the arm are shown. In image A, the bicep pulls the forearm upwards. In image B, the forearm pushes the bicep upwards. In image c, the forearm pulls to the right. In image D, the forearm pushes to the left. Which image would result in the biceps muscle contracting and the forearm being lifted? A B C D.
Option A is correct. The biceps is the muscle that runs down the front of the upper arm. The biceps consists of a single muscle with a "short head" and a "long head'.
What is a bicep muscle?
The biceps is the muscle that runs down the front of the upper arm. The biceps consists of a single muscle with a "short head" and a "long head."
Tough connective fibers called tendons link the biceps to the arm bones. Because the insertion of the bicep muscle is in the forearm, when it contracts, it raises the forearm.
Hence Option A is correct.
