Answer:
A. The car is traveling at a constant speed
Explanation:
When the car was moving north, it was moving 40 miles in 40 minutes. The rate is the same for when the car was traveling west, therefore, the car was traveling at a constant speed.

Which of the following best describes an example of torque?
torque happens when force is applied with a lever in a rotational direction, like twisting a door knob or using a wrench
torque is a non contact force and takes place only through electromagnetism
torque only happens when applied in a vertical direction, like jumping or throwing something up in the air
torque is a force that resists motion, it occurs when two objects make contact
Answer:
Direction of force: these applied forces result in no torque on the wrench because the applied force is parallel to the lever arm.
Answer:
torque happens when force is applied with a lever in a rotational direction, like twisting a door knob or using a wrench.
Explanation:
what is the torque in uniformly rotating fan having blade of length 0.5m?
Answer:
The torque is 0.
Explanation:
The torque for a uniform rotational motion is 0 therefore a fan rotating with a uniform circular motion will have 0 torque.
Two blocks of platinum have a temperature of 200°C. One block has a mass of 10 g, the other block has a mass of 100 g. Do the blocks have the same amount of thermal energy? Explain
Answer:
(Sorry if this sounds too basic)No, it takes more energy to heat up a larger object than a smaller object.
It also takes more energy to vibrate a large amount of atoms than a small amount of atoms.(vibrating something makes something hotter.)
The platinum block with mass 100 g has more thermal energy than the block with mass 10 g and the blocks do not have the same amount of thermal energy.
What is thermal energy?The thermal energy is the energy which is present in a system internally. This energy of the system is present in the state of thermodynamic equilibrium due to its temperature.
Solar energy is an example of thermal energy. The main factor on which the thermal energy depends on-
Mass-The more the mass of an object, results in more the thermal energy it has.Temperature- The more the temperature of an object, more the thermal energy it has.Given that the two blocks of platinum have equal temperature of 200°C. Here, one block has a mass of 10 g, the other block has a mass of 100 g.
As it is known that the thermal energy depends on the mass of the object, and more the mass of an object, results in more the thermal energy it has. Therefore, the block with mass 100 g has more thermal energy.
Hence, the platinum block with mass 100 g has more thermal energy than the block with mass 10 g and the blocks do not have the same amount of thermal energy.

#1 Agriculture inspires people
Farmers have shaped and maintained the unique look of rural areas for millennia. Farms create wonderful variety of landscapes, ranging from beautiful blossoming orchards and vineyards to fields of golden wheat.
And it is not only the 45.7% of people worldwide that live in the countryside [2] that enjoy it, but the rest of population living in urban areas enjoy agricultural landscapes as a place to reconnect with nature.

Explanation:
how can magnets produce electricity?
Answer:
Magnetic fields can be used to make electricity
Explanation:
Moving a magnet around a coil of wire, or moving a coil of wire around a magnet, pushes the electrons in the wire and creates an electrical current. Electricity generators essentially convert kinetic energy
Explanation:
If a magnet is moved back and forth through a coil of wire current can be made to flow through the wire. This is the idea behind electric generators and transformers.
Pls mark me brainliest Hope my answer helps you ❣️Assume that a wave has an amplitude of 1 unit and transports 2 units of energy.
How much energy will the wave transport if its amplitude increases to 4 units?
HELP ME PLEASE!
Answer: 8 units
Explanation: 1 unit = 2 units. That means that a wave transports double the amount of units.
4 units = 8 units because 4 x 2 = 8

This experiment is to see if water flows faster out of a smaller can or a larger can.
You will need:
• two cans (one quite small like a soup can and the other large, like a juice, can.)
Follow these steps:
A. Remove the top of each can. Punch a hole in the side of each can, very close to the bottom, making sure the holes are equal in size. Cover each hole with a piece of tape, and place the cans next to the sink.
B. Put water in both cans, making sure the water is at the same level - different amounts, but the same level. Turn the cans so the holes are facing into the sink, and remove the tape at the same time. Answer these questions: Do the streams of water shoot out at the same distance? Why or why not?
C. Try the same experiment, but this time put one cup of water in each can. What happens to the streams of water now?
D. Try the same experiment, but this time fill both cans to the top. What happens to the streams of water?
ANSWER A B C AND D CORRECTLY!!!
the water flows faster out of a smaller can than it does a larger can.
Answer:
A&B: The stem of the water does not shoot out the same distance because one can have less water and the other can have more water and the can with less water have more pressure that making the can shoot out further than the can with more water.
C: Less water will come out of the two cans because they are compressed together so all of the water is trying to come out all at the same time.
D:All of the water in the can started coming out all in one small stream.

2. How can iron fillings provide evidence that can be used to explain how two magnets exert forces on each other even though the magnets are not in contact with each other?
Answer: When the magnet was placed on the glass it attracted the iron filings
Explanation: iron is a negitive n a postive
Answer: k12 unit test
Iron filings can provide evidence that can be used to explain how two magnets exert forces on each other because each of the magnets can attract iron filings. Another thing is that the patterns of the iron fillings show lines of force that make the magnet's magnetic field. For example, when a magnet is placed in a container and you place iron fillings over the lid it makes a pattern showing the lines of forces making the magnetic field
