Mariam's mother had an ultrasound to see the baby growing inside of her. Which Mariam's mother had an ultrasound to see the baby growing inside of her. Which statement explains how ultrasound works? A special cream is heated and placed on her mother's stomach area, which produces an image on a computer. A fluorescent light is used to transmit light waves into her mother's body, which produce an image on a computer. Sound waves are sent into her mother's body, which reflect off of the baby and produce an image on a computer. A type of medicine is injected into her mother, which causes an image of the baby to be produced on a computer -----How do microwaves cook food? by using electromagnetic waves and the process of radiation by using forced hot air currents through the process of convection by using the movement of charged particles through the process of induction by using direct contact of moving particles through the process of conduction Energy and Its Transformation S 8 P 2. Students will be familiar with the forms and transformations of energy. d. Describe how heat can be transferred through matter by the collisions of atoms (conduction) or through space (radiation). In a liquid or gas, currents will facilitate the transfer of heat (convection).

In the simple act of lighting a match, chemical energy stored in the match In the simple act of lighting a match, chemical energy stored in the match head is transformed into heat and light. What is true about this energy transformation? Most of the energy is lost when the match is struck. New energy in the form of light and heat is created when the match is struck. All of the potential chemical energy is transformed into heat and light energy. Some of the chemical energy is transformed into heat and light and the rest is converted into matter.

For a snack, Bill and Mary heated milk in a pot on the stove For a snack, Bill and Mary heated milk in a pot on the stove for hot chocolate and popped some popcorn in the microwave oven. How did they transfer heat energy to make these snacks? heating milk by radiation; popping popcorn by radiation heating milk by radiation; popping popcorn by convection heating milk by conduction; popping popcorn by radiation heating milk by convection; popping popcorn by conduction

Joe put a cheeseburger sealed in a plastic bag into the microwave, without much Joe put a cheeseburger sealed in a plastic bag into the microwave, without much air in the bag. After it cooked, the bag was full of air. Where did the air come from?

Which of the following is an example of heat transfer by convection? A hot Which of the following is an example of heat transfer by convection? A hot wood stove heats an entire room. The handle of a pot that is being heated becomes warm. A teaspoon in a glass of hot tea becomes warm. The coils of a toaster become red.

A moving bumper car (car 1) collides with a bumper car at rest (car A moving bumper car (car 1) collides with a bumper car at rest (car 2). After the collision, both cars move. If momentum is conserved, which statement is correct? The momentum of car 1 increases and the momentum of car 2 decreases. The momentum of car 1 decreases and the momentum of car 2 increases. The total momentum of both cars decreases.

The ratio of an object’s mass to its volume is its Area Density Perimeter The ratio of an object’s mass to its volume is its Area Density Perimeter Torque

Diving into the ocean, as you go deeper, the water gets colder because the Diving into the ocean, as you go deeper, the water gets colder because the saltiest water is always coldest and sinks to the bottom. there are no waves or wind to mix the hot and cold water. warm water is less dense than cold water, so it stays on top. there are fewer fish and other animals to warm the deep water.

Jupiter has more mass than Earth. Which of these statements would be true about Jupiter has more mass than Earth. Which of these statements would be true about the force of gravity on Rubin, if he were able to visit Jupiter ? It would be Zero on Jupiter It would be smaller, but not zero, on Jupiter It would be the same on Jupiter It would be larger in Jupiter
