A telephone signal uses radio waves which travel at the speed of light.
Traditional communication between people was a Herculean task before the advent of technology. It was quite difficult to pass messages from one point to another.
However, when you call a person on phone, the signal travels across miles speedily because telephone communication makes use of radio waves which are electromagnetic waves and travel at the speed of light.

Nick wanted to see how high an ice cube would float in different temperatures of water. Identify the dependent variable.
A. amount of water
B. height of ice cube
C. size of ice cube
D. temperature of water
E. temperature the ice cube was at its' highest height
Answer:
B. height of ice cube
Explanation:
The height of the ice cube depends on the fifferent emperatures tof the water. You just need to remember that the dependent variable is dependent on the independent variable.

Identify two characteristics shared among transverse waves, longitudinal waves, and surface waves.
Answer: For transverse waves, the waves move in perpendicular direction to the source of vibration.
For longitudinal waves, the waves move in parallel direction to the source of vibration .
They are similar within the sense that energy is transferred within the kind of waves.
Explanation:
The shared characteristics between traverse, longitudinal and surface waves include :
Traverse, longitudinal and surface waves are all mechanical waves They only transport energy without transporting matter.Mechanical waves are simply waves which requires a material medium to propagate. They include longitudinal, surface and traverse waves.
Also, all three waves transfer energy through a medium without the transfer of materials or matter in the medium.
Therefore, all three waves are mechanical waves and do not transfer matter.

2. Calculate the following net forces.
a. Two people push a couch across a room. One pushes with 30 N. The other pushes with 50 N.
b. An uncle plays tug-of-war with his niece and nephew. The uncle pulls one side of the rope with a force of 95 N. The niece and nephew pull the other side of the rope with a force of 40 N and 45 N.
c. Two friends push their friend on a swing with a combined force of 15 N and 20 N.
Text to speech
Answer:
A. The net force is 80 N.
B. The net force is 10 N going more towards the Uncle than the children.
C. The net force is 35 N.
Explanation:
Net force is the sum of the amount of force on either one side (addition) or two sides (subtraction).
Force is an external agent which is responsible for changing a body's state of rest or motion. It is the push or pull on an object. The net forces acting on the body are 80 N, 10 N and 35 N.
What is a net force?The sum of all the forces acting on an object is defined as the net force. The net force is able to accelerate a mass. The net force is known as a term which is used in a system when there is a significant number of forces.
When we apply a force on a body, apart from the applied force, there are many other forces acting like gravitational force, frictional force and the normal force.
The net force acting on a body is given as:
Fnet = F₁ + F₂ + F₃ + .....Fₙ
a. Fnet = 50 + 30 = 80 N
b. Fnet = 95 - (40 + 45) = 10 N
c. Fnet = 20 + 15 = 35 N

Tiffany was investing how fast it took Hayden to react to different sounds. Identify the independent variable.
A. how fast Hayden reacted
B. different sounds
C. playing the trumpet over and over
D. how much time it took Hayden to react
E. Hayden
Answer:
B. Different sounds
Explanation:
The independent variable is the variable that changes. So B is the independent variable because the sounds are what change.
Different sounds are the independent variable. Hence, option B is correct.
What is the independent variable?It is a variable that stands alone and isn't changed by the other variables you are trying to measure.
The independent variable is the variable that changes.
So B is the independent variable because the sounds are what change.

Explanation:
Are the forces on an object in motion balanced? Why or why not?
Answer:
An object's motion can be changed by unbalanced forces. Balanced forces do not change the motion of an object. The motion of an object will not change if the forces pushing or pulling the object are balanced. An object that is sitting still will stay still if the forces acting on it are balanced.
