A couch is pulled on the left side with 10 N of force and on the right side, it’s pushed with 3 N of force. The net force acting on the couch is:
7 N to the left
13 N to the left
7 N to the right
13 N to the right
A couch is shown with two forces acting on it: 10 N to the left and 3 N to the right.
The couch will not move due to the force being equal or balanced.
The couch will move to the left due to an unbalanced force. The net force will be 13 N.
The couch will move to the left due to an unbalanced force. The net force will be 7 N.
The couch will move to the right due to a balanced force. The net force will be -7.
A smooth card is placed over a drinking glass. A penny is placed in the middle of the card. When the card is hit with the index finger, the card moves away, and the penny drops into the glass. Which statement best explains why the penny does not move in the same direction as the card?
There is an absence of friction between the penny and the card.
The penny has more inertia than the card.
The card exerts too much force on the penny.
There is a little gravity between the card and the penny.
What are electromagnetic waves?
Waves created by vibrating electric charges that can travel through a vacuum or through matter.
The process by which an object is made to vibrate by absorbing energy at natural frequencies.
A point in a standing wave at which the interfering waves always cancel.
A wave pattern that forms when waves of equal wavelength and amplitude, but traveling in opposite directions, continuously interfere with each other.
Microwaves are:
a type of sound wave
a type of electromagnetic wave
a type of mechanical wave
a type of gravitational wave
What are gamma rays?
They have the longest wavelength with the lowest frequency and have the least energy. They carry television, radio, & cell phone signals.
These waves will cook your popcorn in just a few minutes, but they're also used by astronomers to learn about the structure of nearby galaxies.
Used in remote controls to change the channel on your television. All warm bodies give off these waves. Used in night vision goggles. They can be used for seeing people in the dark.
Doctors use these waves to see inside your body. These are the shortest waves with the highest frequency and have the most amount of energy. They are used on some foods to kill bacteria that make food spoil quickly.
