Answer:
I think its 12 cm itself. Because in the question it is said that the length is same in all temperature
Answer:
to the left the first answer can be "Consumer" and under it can go "plant"
to the right the first answer on the top can be "Carnivore" under it can go "Herbivore" and under it can go "Producer"
I just had this question and its right
mass and velocity
Explanation:
Momentum depends on two important factors which are the mass and velocity of a body.
Momentum = mass x velocity
- Momentum can be defined as the product of mass and velocity.
- It is a vector quantity that has both magnitude and directions.
- Momentum is a very important quantity in physics as it shows the impact of a force on another.
- The unit is Kgm/s²
- It is the same as impulse.

Answer: When you speak into the can, your voice creates air vibrations that travel into the can, vibrate the bottom of the can, which in turn vibrates the string all the way over to the other can, in turn vibrating the other can's bottom, then the air again.

Explanation:What is centripetal acceleration?
Can an object accelerate if it's moving with constant speed? Yup! Many people find this counter-intuitive at first because they forget that changes in the direction of motion of an object—even if the object is maintaining a constant speed—still count as acceleration.
Acceleration is a change in velocity, either in its magnitude—i.e., speed—or in its direction, or both. In uniform circular motion, the direction of the velocity changes constantly, so there is always an associated acceleration, even though the speed might be constant. You experience this acceleration yourself when you turn a corner in your car—if you hold the wheel steady during a turn and move at constant speed, you are in uniform circular motion. What you notice is a sideways acceleration because you and the car are changing direction. The sharper the curve and the greater your speed, the more noticeable this acceleration will become. In this section we'll examine the direction and magnitude of that acceleration.
The figure below shows an object moving in a circular path at constant speed. The direction of the instantaneous velocity is shown at two points along the path. Acceleration is in the direction of the change in velocity, which points directly toward the center of rotation—the center of the circular path. This direction is shown with the vector diagram in the figure. We call the acceleration of an object moving in uniform circular motion—resulting from a net external force—the centripetal acceleration
