Abigail, Charlotte, and Sophia are on a space adventure! They learn that the electromagnetic spectrum includes radio waves, infrared waves, ultraviolet waves, and X rays. They wonder, which property remains constant in a vacuum for all parts of this spectrum?
frequency
wavelength
period
speed
Mia, Grace, and Lily are in a science competition. They are given a challenge to calculate the velocity of a wave. The wave has a frequency of 1,000,000 hertz and a wavelength of 10,000 meters. Can you help them solve this?
(1,000,000Hz) ÷ (10,000m)
(1,000,000Hz−10,000m)
(1,000,000Hz+10,000m)
(10,000m) × (1,000,000Hz)
Zoe, Avery, and Arjun are having a science experiment competition! They each chose a different liquid sample and are going to add 1000J of heat to see which one's temperature will rise the most. The masses and specific heats of their chosen liquids are shown in the table below. Can you guess whose liquid's temperature will rise the most?
Zoe's water
Avery's glycerin
Arjun's methanol
cooking oil (not chosen by anyone)
Imagine this! Our friend Ethan is in a science lab and he touches a cool metal sink with his finger. He notices that his finger feels cold. Nora and Abigail are curious about this. Which of the following statements do you think explains Ethan's observation?
Ethan's finger was originally at a lower temperature than the sink.
Ethan's finger was originally at the same temperature as the sink.
Heat energy flows from the metal sink to Ethan's finger.
Heat energy flows from Ethan's finger to the metal sink.
Isla, Maya, and Abigail are having a heated debate about the wave nature of light. They all agree on most points, but there's one thing they can't agree on. Can you help them out? Which of the following CANNOT be explained by the wave nature of light?
Isla thinks it's reflection
Maya argues it's diffraction
Abigail is sure it's the photoelectric effect
Or is it interference patterns?
Imagine Sophia, Maya, and Avery are at a rock concert. The band on stage is moving further away while playing their instruments. How would the sound waves received by Sophia, Maya, and Avery compare with those emitted by the band?
They would hear the music as having a greater velocity.
They would hear the music as having a higher frequency.
They would hear the music as having a lower frequency.
They would hear the music as having a smaller wavelength.
It's a sunny but cool day. Mia, Kai, and Priya are planning to go out for a picnic. They all have T-shirts in four different colors: Black, Pink, White, Yellow. Mia suggests that they all wear black T-shirts. She explains that black will absorb more of the sun's light than the other colors, helping them stay warm. Which property of light is Mia referring to?
Absorption
Brightness
Reflection
Refraction
Identify which letter in the diagram represents each of the following: radiation, conduction, and convection. Answer on a separate sheet.
Aiden, Abigail, and Oliver are having a fun science discussion. They are comparing the masses and velocities of several moving things. They are trying to figure out which of the things listed has a momentum closest to that of a 0.145 kg baseball moving at a velocity of 45 m/s. Can you help them out?
Aiden's pet dog
Oliver's toy truck
Abigail's steel pellet
A toy car in their classroom
A 1000 kg car accelerates from rest to 6.0m/s. What is the magnitude of the car's final momentum?
In your description, be sure to include; the identity of each numbered area in the diagram, how a change in frequency would affect the relationship between numbered areas 1 and 3. Write your answer on a separate sheet.
As Jane approaches a stop sign, she applies a braking force of 10,000 N. Her car has a mass of 2,000 kg and is moving with a velocity of +20 m/s. What is the impulse imparted to bring the car to a stop?
Suppose that an astronaut gave the 2kg wrench a speed of 10m/s rather than 5m/s. What effect would this have on her own recoil speed?
Two 1kg balls, traveling at +1m/s and −1m/s, respectively, collide with each other and stick together after impact. What is their velocity after the collision?
Imagine Nora, Sophia, and Maya are on a thrilling adventure to uncover the secrets of waves. They stumble upon a peculiar wave property that remains constant, regardless of distance, damping, or even when the wave travels through different materials. Can you guess what this property is?
frequency
wavelength
amplitude
velocity
A water wave has a frequency of 2 Hz and a wavelength of 1.5 m. What is the speed at which this wave travels?
Liam, Emma, and Avery are experimenting with a closed loop of wire. They are curious to know under which set of conditions will they be able to produce an electric current in it. Can you help them?
By decreasing the distance between the ink particles and the drum
By increasing the distance between the ink particles and the drum
By changing the charge of the ink particles to positive
By changing the charge of the drum to negative
Maya, Zoe, and Aiden are having a debate. Maya thinks a battery converts nuclear energy to electrical energy, Zoe thinks it's thermal energy, and Aiden believes it's mechanical energy. However, one of them is correct. Can you guess who?
Maya - Nuclear Energy
Zoe - Chemical Energy
Aiden - Thermal Energy
None of them
