Marco is conducting an experiment. He knows the wave that he is working with has a wavelength of 32.4 cm. If he
measures the frequency as 3 hertz, which statement about the wave is accurate?
O The wave has traveled 32.4 cm in 3 seconds.
The wave has traveled 32.4 cm in 9 seconds.
O The wave has traveled 97.2 cm in 3 seconds.
O The wave has traveled 97.2 cm in 1 second.

Answers

Answer 1

Answer:

By using the wave speed formula, v=fλ

v = 3(32.4)

= 97.2 cm/s

The wave has travelled 97.2 cm in 1 second.

Answer 2

Answer:

Speed = 32.4 * 3

Speed = 97.2 m/s

so, the wave has traveled 97.2 cm in 1 second.

1. Momentum = mass x velocity

2. Based off the answer to the first question, by hitting the ping pong ball, momentum is transferred from the boy to the ball. Causing the ball to have more velocity/speed and gain more momentum.

3. Momentum before = momentum after
Every time the ball hits the table, some momentum transfers from the ball to the table. Every time the player hits the ball, some momentum transfers from the player to the ball. This allows the player to continue playing ping pong as the ball always has momentum.

What happens to the atoms that make up hydrogen fuel as it burns?

Answers

Answer:

When hydrogen fuel burns, its atoms combine with oxygen atoms in the air, which creates a chemical reaction that releases energy in the form of heat and light. The hydrogen atoms lose their outermost electrons, becoming positively charged ions (protons). These ions combine with the oxygen atoms to form water molecules (H2O), which evaporate into the air as steam. Therefore, the atoms that make up hydrogen fuel ultimately become part of water molecules during the process of combustion.

Explanation:

When hydrogen fuel burns, its atoms combine with oxygen atoms to form water molecules. So the atoms that make up hydrogen fuel become part of the water molecules.

What's a chemical change

Answers

Answer:

the appearance of a new substance,

irreversible change has occurred

the absorption or release of energy.

Explanation:

Chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. These processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. Some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. Understanding chemical changes is a major part of the science of chemistry.

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.

Morse code was invented and first used before the invention of the telephone. Explain how using electronic pulses to send messages in Morse code would have been an advantage over using your voice.

Answers

Answer:

Using electronic pulses to send messages in morse code would be an advantage over using your voice because not everyone could understand morse code. If you wanted to send a message and didn't want someone to overhear you say it you could use morse code to send the message quietly. Seeing that everyone doesn't know morse code you could send almost secret messages using it.

Explanation:

ANSWER-

Using electronic pulses to send messages in Morse code was an advantage over using voice because it allowed for long-distance communication without the need for a physical connection, such as a telephone line. The signals could be sent over telegraph wires or even through air, making communication faster and more efficient. Additionally, Morse code could be sent silently, making it ideal for covert communication.

What type of person studies and collects data on the weather?

Answers

The answer would be a Meteorologist

Meteorologist is a person who studies and collects data

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
