In the early 1900s many scientists thought that an atom consisted of a positive substance with negative charges scattered throughout the substance. Then Ernest Rutherford made a discovery that led to the understanding that an atom consists mostly of empty space with- * 20 points A. protons orbiting a dense nucleus made of electrons and neutrons B. Neutrons and protons orbiting a cloud of electrons C. Electrons and protons orbiting a cloud of neutrons D. Electrons orbiting a dense nucleus made of protons and neutrons
Answer:

Explanation:
3. A recent flood in the area has caused many short-term changes to
the ecosystem. Which is a long-term change?
A. Standing water in the streets and sewers
B. Temporary displacement of organisms
C. Permanent change in the landscape
D. Poor water quality in rivers and streams
Answer:
c
Explanation:
While standing water in the streets and sewers (option A) and poor water quality in rivers and streams (option D) may persist for some time after the flood, they are generally considered short-term changes as they can eventually be remedied through clean-up efforts and restoration programs.
Temporary displacement of organisms (option B) can also be considered a short-term change, as organisms will eventually return to their original habitats once conditions improve.
However, a permanent change in the landscape (option C) such as altered river channels, new water bodies, or changes in topography, can have lasting effects on the ecosystem and its inhabitants. These changes may alter habitat suitability, nutrient cycling, and water availability, which can impact the ecosystem for years or even decades to come.
Answer: C
Explanation:
The landscape could be flooded. Houses and buildings may be restricted.

Which criteria do scientists consider when they classify soil? Check all that apply.
soil profile
climate
soil composition
bedrock
soil horizon
Answer:climate soil composition
Explanation:
Soil composition, scientists consider when they classify soil. Therefore, the correct option is option C.
What is soil?The bioactive, porous media that has grown in the top layer of the Earth's crust is known as soil. Being a source of water as well as nutrients, a filter for harmful wastes, a site for their breakdown, and a participant inside the cycle of carbon as well as other substances through the planet's ecosystem, soil constitutes one of the main substrates of life on Earth.
It has changed as a result of weathering processes influenced by geographical, geologic, biological, and climatic factors. Soil composition, scientists consider when they classify soil.
Therefore, the correct option is option C.

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.
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)
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
kinetic energy is given as
2) when speed is 3 m/s
kinetic energy is given as
3) when speed is 4 m/s
kinetic energy is given as
4) when speed is 5 m/s
kinetic energy is given as
5) when speed is 6 m/s
kinetic energy is given as

Many systems and technologies have been designed to communicate over long distances. They all send information that has been encoded into a signal. What must a receiver be able to do to understand a signal that is being sent to them?
The diagram above shows the repeating groups of atoms that make up two samples. Both samples are solids at room temperature. Will the other properties of the two samples likely be the same or different? (Examples of properties are smell, color, and the temperature at which a substance melts.)
{It's not 'C' according to my teacher}
Answer:Based on the diagram, the repeating groups of atoms in the two samples appear to be different. Therefore, it is likely that the other properties of the two samples will also be different. This is because the properties of a substance are determined by its chemical composition and molecular structure. Since the two samples have different repeating groups of atoms, their chemical compositions and molecular structures are likely to be different, leading to differences in their properties such as smell, color, and melting point.

What's one major difference between the earth's greenhouse effect and an actual greenhouse?
Heat escapes from a greenhouse more easily than it does from Earth's atmosphere
The glass in a greenhouse traps heat, while greenhouse gases in the atmosphere absorb and recycle heat
Actual greenhouses are cold in winter, while the
greenhouse effect has led to warm winters across the
earth
There is no significant difference; both work pretty much the same way

1. Using D10W and a vial of NaCl 4 mEq/mL, how many mL of NaCl are needed to prepare 250 mL of a
D10/NS solution?
a. 4.8mL
b. 9.6ml
c. 19.6mL
d. 154mL
To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.
