Ik Im Not Right.. Or Am I?

Answers

Answer 1

Answer:

C

Explanation:
Average Speed = total distance covered / total time taken

the distance she covered didnt change because the race track stayed 5km.
However, she did take a longer time to complete the race because she stopped in the middle to tie her shoes
Therefore, C is the answer.

2. it is a cold current in the pacific ocean
3. it carries warm water from the americans to western europe
4. it moderates the climate of western europe
5. it makes westerns europes climate more harsh

Answers

1. It is a warm current in the Atlantic Ocean 3. It Carrie’s warm water from the Americans to Western Europe 4. It moderates the climate of Western Europe. Those are the three answers

The three correct options are:

1. It is a warm current in the Atlantic Ocean.

3. It carries warm water from the Americas to Western Europe.

4. It moderates the climate of Western Europe.

The Gulf Stream is a warm and swift ocean current in the Atlantic Ocean, originating in the Gulf of Mexico and flowing northeastward along the eastern coast of the United States and Canada. It carries warm waters from the tropics towards the North Atlantic region, including Western Europe.

As it moves across the ocean, it helps to moderate the climate of Western Europe by releasing heat, thereby making the winters milder and the overall climate more temperate. The Gulf Stream plays a crucial role in influencing the weather patterns and maintaining a relatively mild climate in Western Europe compared to other regions at similar latitudes.

Do you think a moving skateboard has energy? Why or why not?
PLEASEEEEEE HURRY

Answers

Answer:

"Yes," a moving skateboard has energy.

When the skater seems to be in motion or throughout a movement, the potential energy converts itself into the kinetic form of energy, and then it becomes potential energy again.

Furthermore, somewhere after every movement, the same skateboarder was around a similar height, — in other words thus every time it is equally powerful.

The response is thus the right one.

Explanation:

Yes, every object in motion has energy.

What happens to air pressure and amount of oxygen as the altitude increases in Earth's atmosphere? 1. Air pressure decreases, while the amount of oxygen increases. 2. Both air pressure and the amount of oxygen increase. 3. Air pressure increases, while the oxygen decreases. 4. Both air and oxygen decrease.

Answers

Answer:

As altitude increases in Earth's atmosphere, both air pressure and the amount of oxygen decrease.

At sea level, the air pressure is about 1013.25 millibars (mb) and the concentration of oxygen is about 21%. As you go higher in the atmosphere, the air becomes thinner and less dense, so the air pressure decreases. At the same time, the concentration of oxygen also decreases because there is less air overall to contain oxygen molecules.

This is why it is harder to breathe at high altitudes, such as on a mountain. The air is less dense, so there are fewer oxygen molecules per breath and the body has to work harder to get enough oxygen.

Answer:4: Both Air and Oxygen decrease.

Explanation:This is in accordance with Henry's law. As pressure decreases solubility of gases decreases. Air pressure decreases as we altitude increases and the decrease in oxygen level is the consequence ,

A voltaic cell, also known as a galvanic cell or an electrochemical cell, is an electrochemical device that generates electrical energy through a spontaneous chemical reaction. It consists of two half-cells connected by an external circuit and a salt bridge or porous barrier that allows the flow of ions between the two half-cells.

Answer: Clothes purely made of synthetic fibers are not comfortable in a hot and humid environment as they don't have the property to absorb water or sweat quickly so their water-resistant property makes them unsuitable for hot humid environment .

Explanation:

Mixing of synthetic fiber and natural fibers enhances the properties such as strength, elasticity, and ease of ironing and washing. Generally in hot environments it is preferred to wear a mixture of synthetic and natural fiber than wearing only clothes made from synthetic fiber .

Moreover, mixing synthetic fibres with natural fibres enhances their properties, such as strength, elasticity and ease of washing and ironing. Hence, these days clothes made out of a mixture of synthetic fibres and natural fibres are more popular than those made purely out of synthetic fibres.

The statement "The variety of species on earth today is greater than before" is false. Therefore, option D is the false statement.

Fossils have shown that there were trees and other plants in areas of the earth, and plants were of great size in comparison to today. Records also show that there were large animals, like mammoths and dinosaurs, that lived on Earth before the flood.

However, there is no scientific evidence to support the claim that the variety of species on Earth today is greater than before the flood.

In fact, the fossil record suggests that there were many species of plants and animals that existed in the past that are now extinct, meaning that the overall variety of life on Earth may have been greater in the past.

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)

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
