HELP! 100 POINTS! A cinder block is pulled 0.50 meters to the right in 3 seconds. What is the block's average speed to the nearest hundredth of a meter per second (m/s)?

Answers

Answer:
The average speed of the blocks are 0.36 m/S.
Explanation:
Average speed is defined as the ratio of distance covered per unit time. So if it is said that blocks are pulled to 0.9 m in the right side. This means the blocks cover a distance of 0.9 m from the origin and that distance is covered in 2.5 s. Thus, the average speed can be calculated from the change in speed
with respect to time. As at time t = 0, the speed is
also zero, and at time t = 2.5 s, the speed will be
Speed =
0.9 = 0.36
2.5
Since, in this case, the speed is equal to the average speed of blocks. So the average speed of the blocks will be 0.36 m/s.

Speed = 0.9 = 0.36
2.5
Since, in this case, the speed is equal to the average speed of blocks. So the average speed of the blocks will be 0.36 m/s.

A student wants to know how the number of geese in a study area affects the number of parts in their songs. She performs an experiment and records the data in a table.
Which two terms describe this type of data?

A.
Quantitative

B.
Empirical

C.
Theoretical

D.
Qualitative

Answers

Theoretical did this question

The two terms that describe this type of data are Quantitative and Qualitative. Therefore, the correct options are A and D.

Data that can be measured and expressed numerically, denoting quantities or amounts, is called quantitative data. In this example, the number of geese is counted and correlated with the number of pieces in their symphony. Instead of being numerical, descriptive and categorical data are called qualitative data. In this example, it is observed and noted how many sections are in the swan songs (descriptive categories).

Therefore, the correct options are A and D.

Describe how minerals form.

Answer : Minerals can form on the surface through evaporation of solutions containing dissolved minerals. Minerals can form beneath the surface when dissolved elements and compounds leave a hot water solution or when materials melted in magma/ lava then cools & hardens.

How does the arrangement of the atoms in a mineral relate to its properties?

The atoms in a mineral are arranged in an organised 'atomic structure'. They connect together to form molecules, and the molecules stack together in a regular pattern to form a crystal. The shape of a crystal depends on the way the molecules are stacked up inside it.

Why do the atoms in a molecule want to be so far apart? (Mention Electron domains/Electrons)

Answers

Answer:

Because like chargee repel, two molecules will resist being brought close together.

Explanation:

The shorter the distance is between them, the more energy it takes to push them to get even closer. If the molecules approach each other with sufficient energy, however, they may exchange atoms or even form a bond( chemical reaction)

Based on the weather map, state the direction of the warm front. Using complete sentences predict the effect of the warm front on any one city shown on the map. Will this prediction always come true? Why or why not? (7 points)

Answers

Answer:

yes and no because it is warm in one spot and cold in the other.

Explanation:

Answer:

The warm front is moving Northeast towards Chicago. It rained in Chicago, the area is humid and when the warm front comes the place will be raining again. Since warm front come slowly, the rain will be there for a few days. After a warm front passes, the weather tends to be warm and humid. This prediction might not always come true because mother nature sometimes is not always predictable.

The data you’ll use is in the first two columns: Year and Anomaly. An anomaly describes a deviation from the standard or long-term average. The anomaly data in the table compares the global land and ocean temperature with the average temperature from 1901 to 2000, which was 13.9°C.

Anomalies more accurately describe climate variability over larger areas than absolute temperatures do, and they give a frame of reference that allows more meaningful comparisons between locations and more accurate calculations of temperature trends.

Why is farming important?

Among the various ways that agriculture has an impact on society are the provision of food, habitat, and employment opportunities; the provision of raw materials for food and other goods; and the development of robust economies through commerce.

Why is farming beneficial to the environment?

A large number of species use pasture and crops as both a habitat and a source of food, making up around 50% of the planet's livable land. Sustainable management of agricultural operations has the potential to safeguard watersheds, restore significant habitats, and improve the quality of the soil and water supply.

When the speed of the bottle is 2 m/s, the KE is kg m2/s2. When the speed of the bottle is 3 m/s, the KE is kg m2/s2. When the speed of the bottle is 4 m/s, the KE is kg m2/s2. When the speed of the bottle is 5 m/s, the KE is kg m2/s2. When the speed of the bottle is 6 m/s, the KE is kg m2/s2.
instructions
In this part of the experiment, you will be changing the speed of the bottle by dropping it from different heights. You will use the same mass, 0.250 kg, for each trial, so record this mass in Table B for each velocity. Then, calculate the expected kinetic energy (KE) at each velocity. Use the formula KE = mv2,
where m is the mass and v is the speed. Record your calculations in Table B of your Student Guide.

Answers

Answer:

Based on the given instructions, you need to calculate the expected kinetic energy (KE) at each velocity using the formula KE = mv^2, where m is the mass and v is the speed. The mass is given as 0.250 kg.

Table B: Calculation of Kinetic Energy (KE)

Speed (m/s)Mass (kg)KE (kg m^2/s^2)20.2500.50030.2500.75040.2501.00050.2501.25060.2501.500

To calculate the kinetic energy at each velocity, multiply the mass (0.250 kg) by the square of the velocity.

For example, when the speed of the bottle is 2 m/s: KE = (0.250 kg) * (2 m/s)^2 = 0.250 kg * 4 m^2/s^2 = 1.000 kg m^2/s^2

Perform similar calculations for the other velocities and record the results in Table B.

Answer:

Explanation:mass of the bottle in each case is M = 0.250 kg

now as per given speeds we can use the formula of kinetic energy to find it

1) when speed is 2 m/s
