write, explaining how you find the volume of a regular shaped object and an irregular shaped object.
Answer: For the volume of a regular shaped object, multiply the width and the length and then multiply the result by the height. As for the volume of an irregular shaped object, first break the object down into more regular shaped objects. Then calculate the volumes of the small regular shaped objects, and add all the volumes to get your answer.
Jack, a student, travels to school 10 miles every morning. The speed limit is 25 miles/hour. How long it takes Jack to get to his school?
Answer:
0.4 hour or 24 minutes
Explanation:
Speed =displacement /time
25miles/hour=10/time
10/25=time
0.4hour=time
Answer:
24 minutes
Explanation:
• If the speed limit is 25miles/hour, it takes 2.4 minutes to travel 1 mile.
60mins/25miles
= 2.4 minutes
• Therefore to travel 10 miles;
2.4 minutes × 10
= 24 minutes

How do density, pressure, and temperature change as the depth of Earth increases? Question 5 options: Density, pressure, and temperature all increase as you go deeper into the Earth. Density, pressure, and temperature all decrease as you go deeper into the Earth. Density decreases, and pressure and temperature increase as you go deeper into the Earth. Density and pressure decrease, and temperature decreases as you go deeper into the Earth.
Answer: Density, pressure, and temperature all increase as you go deeper into the Earth.
Explanation: Explanation: As you go deeper in depth, pressure increases. Density = mass/volume. The layers beneath us due to pressure get packed to the point of being very dense.

Which lists types of materials from most conductive to least conductive?
insulator, semiconductor, conductor, superconductor
superconductor, conductor, semiconductor, insulator
conductor, insulator, semiconductor, superconductor
semiconductor, conductor, superconductor, insulator
Answer:
superconductor conductor semiconductor insulator
Explanation:
Edge
The list's type of materials from most conductive to the least conductive will be superconductor,conductor,semiconductor and insulator.
What are semiconductors?Semiconductors are materials with conductivity intermediate between conductors and nonconductors or insulators. Semiconductors may be either compound like gallium arsenide.
The ideas, characteristics, and mathematical techniques that control semiconductors are explained in physics.
Silicon is employed in the manufacturing of electrical circuits, whereas gallium arsenide is used in solar cells, laser diodes, and other applications.
The types of materials from most conductive to least conductive will be superconductor,conductor,semiconductor and insulator.
Hence, option B is correct.
