Explanation:

Debby and Ben took different routes to travel from Point A to Point E. Debby took the route along A, B, C, D, and E. Ben took the route along A, G, F, and E. Debby and Ben both took 4 hours to complete their walk. Their routes are shown. (3 points)



Which statement is true about Debby and Ben's average speed?
Ben and Debby's average speed was the same.
Debby's average speed was twice Ben's average speed.
Ben's average speed was twice Debby's average speed.
Debby's average speed was three times Ben's average speed.

Answers

Answer:

Ben's average speed was twice Debby's average speed.

Explanation:

Ben covered a total distance of 16 miles (10+4+2) and Debby covered 8 miles (3+2+2+1) which is half of what Ben covered. As they both reached the place in the same amount of time it tells us Ben was faster.

Bens was twice debbys speed.

You sit with friends around a campfire, roasting marshmallows. Which
transfer of thermal energy involved in this system is an example of
conduction?
O A. Thermal energy moves through the air from the flames to the
marshmallow.
B. Thermal energy moves within the air above the flames as warmer
air rises.
C. Thermal energy moves from the marshmallow to your fingers as
you touch the marshmallow.
D. Thermal energy moves through the air and warms your hands and
face.

Answers

The transfer of thermal energy involved in this system which is an example of conduction is "thermal energy moves from the marshmallow to your fingers as  you touch the marshmallow."

Conduction is the movement of thermal energy without the actual movement of the particles of a body. They particles only collide with each other and transfer energy in the process while maintaining their mean positions.

When you touch the marshmallow, you feel the heat by conduction. Hence, the transfer of thermal energy involved in this system which is an example of conduction is "thermal energy moves from the marshmallow to your fingers as  you touch the marshmallow."

With energy, changes in the physical world are possible. These can be a change in speed, a change in direction, a change from cold to hot, and many other kinds of changes.

Question 4 options:
True
False

Answers

true because energy can change its speed because of temperature and also its direction

According to the Law of Conservation of Energy, the energy in a closed system is constant

The correct option for changes in the physical world are possible with energy, is the option;

True

Reason:

According to the Law of Conservation of Energy, energy cannot be created nor destroyed, but can be changed from one form to another

Therefore;

The changes in speed which is the change in kinetic energy is possible

Change in direction which is a change in velocity  vector is change in kinetic energy is possible

Change from cold to hot by the addition of heat energy  and other forms of energy

Therefore, the correct option is; True changes in the physical world are possible

Write a paragraph of five sentences or more explaining how the radio uses the behavior and characteristics of the radio wave to function.

Answers

Answer:

Radio waves have the longest wavelengths in the electromagnetic spectrum.You can tune a radio to a specific wavelength—or frequency—and listen to your favorite music. The radio "receives" these electromagnetic radio waves and converts them to mechanical vibrations in the speaker to create the sound waves you can hear.

Calculate the speed of the object from 5 seconds to 10 seconds. Show your work and don't forget to include the units. (HINT for distance, make sure you are telling me the total distance traveled from 5 seconds to 10 seconds... no it is not 5 meters)

Answers

Answer:

Given

mᴀ = mʙ = mᴄ = 62 kg

Fᴀ = 480N

Fʙ = 240 N

Fᴄ = 600 N

Asked

aᴀ, aʙ, aᴄ = ?

Solution

    Based on the question, we know that the mass of road A, road B and road C are same. And, the formula of acceleration is

           

so, we can calculate the acceleration of road A, road B and road C.

• for road A

aᴀ = 7,7419 m/s²

aᴀ = 7,75 m/s²

• for road B

aʙ = 3,8709 m/s²

aʙ = 3,87 m/s²

• for road C

aᴄ = 9,6774 m/s²

aᴄ = 9,68 m/s²
