The slope of a speed time indicates

Answers

Answer 1
Answer: The slope of a peed versus time graph indicates acceleration. You can prove this by the fact that slope is Δy/Δx and the units for y are m/s and for x are s which means that the slope has the units (m/s)/s which are the same units used for acceleration.
I hope this helps.  Let me know in the comments if anything is unclear.

In which of these situations is convection most likely the main form of heat transfer?Warm air from a heater on the first floor of a house moves to the upper floors.

The sides of a metal pan become hot when the pan is placed on a stove burner.

A person gets a sunburn from lying on the beach too long.

An ice cube melts when a person holds it in his hand.

Answers

In the first situation: the mechanism of covection is the main form of heat transfer when warm air from a heater moves around and upward.

In the case of the metal pan the mechanism of heat transfer is conduction.

In the case of sunburn the mechanism is radiation.

In the case of an ice cube melting in a hand, conduction is the most important mechanism.

Answer:

An ice cube melts when a person holds it in his hand.

Describe the difference between polar covalent bonds and nonpolar covalent bonds using these two molecules - H2 and HCl. Which molecule contains a polar covalent bond and which molecule contains a nonpolar covalent bond? Explain your reasoning alongside describing the differences between the types of bonds.

Answers

Polar covalent bonds are between atoms with different electronegativities, whereas nonpolar covalent bonds are between atoms with the same electronegativity.

This means that HCl is a polar covalent bond, whereas H2 is a nonpolar covalent bond.

2 ways in which the carbon is stored for a long time

Answers

1) Carbon can be stored as chemical energy in the cells of the plant or the animal. So, the carbon will stay stored as part of the organic material that makes up the plant or animal until it dies. When a plant or animal dies, it either decomposes and the carbon is released back into the environment; or the organic material of the organism is buried and transformed over millions of years into coal, oil, or natural gas. 
2)Another way that carbon is stored for long periods of time is when carbon is used by ocean organisms. Many ocean creatures use calcium carbonate (CaCO3) to make their shells or to make the reef material where coral animals live. When algae die, their organic material becomes part of the ocean sediments, which may stay at the bottom of the ocean for many years. Over millions of years, those same ocean sediments can be forced down into the mantle when oceanic crust is consumed in deep ocean trenches. As the ocean sediments melt and form magma, carbon dioxide is eventually released when volcanoes erupt.

What are a few examples of what energy is?​

Answers

✅Energy exists in many different forms✅

Examples of these are: light energy, heat energy, mechanical energy, gravitational energy, electrical energy, sound energy, chemical energy, nuclear or atomic energy and so on. Each forms can be converted or changed into the other forms.

Prior to the Civil War, the North had 80 percent of the _____ capacity in the United States.A. agricultural
B. political
C. manufacturing
D. military

Answers

Answer:

C. manufacturing

Explanation:

With the Independence of the Thirteen Colonies in 1776, the colonies became independent states, but united in a Federation, with republican and presidential political representation. States in the northern region concentrated on the development of industry and, to that end, needed free and salaried labor to operate the work within the factories. Prior to the secession war, the northern states had 80 percent of manufacturing capacity in the United States. The formation of the working class and the industrial bourgeoisie in the North has also produced a specific way of looking at political activity and civil rights.
The North had 80% of the manufacturing capacity in the U.S. before the Civil War. The North was filled with factories, whereas the South relied on farming and slaves to survive, they produced a lot of cotton and tobacco for example. During the Civil War as you could imagine, the North was making a lot of artillery, so its economy began to expand more to meet the demands of war.
