IPC Final Exam Review 2024

Students used rope to model radio waves and microwaves. Compared to the model of radio waves, the model of microwaves has a greater —

• period
• amplitude
• wavelength
• frequency

A student uses a springy metal coil to model a wave, as shown below. Which type of wave is most like the student's model?

• Longitudinal wave
• Standing wave
• Diffraction wave
• Transverse wave

A veterinarian installs a programmable microchip under the skin of a new pet that, when scanned, gives off a signal that indicates the name of the owner and the vaccinations the pet has been given. What type of wave would be the safest and most effective for this microchip to use?

• Light waves
• Microwaves
• Radio waves
• Infrared waves

A submarine sonar transmitter emits a burst of waves while submerged. The waves reflect off an object in the distance and return to the submarine. The time that it takes for the waves to travel to the object and return to the submarine tells the sonar operator —

• the weight of the object
• the contents of the object
• the wavelength of the object
• the distance of the object from the submarine

A student observes a Newton’s cradle as she raises two of the masses as shown in the diagram below. What will most likely occur when the student releases the two masses?

• Masses 1 and 2 will stop when they swing into and hit mass 3.
• Masses 1 and 2 will bounce off of mass 3.
• Masses 4 and 5 will swing out in the opposite direction.
• Mass 5 will swing out in the opposite direction twice as high as 1 and 2 were held up.

A small group of children were observed playing at a local park. One child shared a bag of chocolate candies by pouring a small amount into the hands of her friends. After consuming the candy, the children wiped their chocolate-covered hands on their pants. Which of the following statements correctly explains why the children had chocolate on their hands?

• Thermal energy from the candy was transferred to the child’s hand.
• Thermal energy from the child’s hand was transferred to the candy.
• Chemical energy was transformed into thermal energy.
• The candy melted because it was a clear, sunny day.

The transfer of thermal energy is always ―

• upward
• from cooler to warmer
• downward
• from warmer to cooler

How does heat energy from the Sun reach the Earth?

• Radiation
• Convection
• Sublimation
• Conduction

A teacher asks students to decrease their kinetic energy. What could the students do in order to decrease their kinetic energy the most? TR1.5A

• Jump up and down
• Run to the front of the classroom
• Sit down and stop moving
• Stand up and move their arms

A student wants to place a ball on an inclined plane where it will have the greatest potential energy. Where on the inclined plane will the student place the ball? TR1.5B

• Location A
• Location B
• Location C
• Location D
