- The length of a highlighter pen is measured as 115underline ( ). Which of these units should fill the gap? milligrams (mg) millimetres (mm) grams (g) centimetres(cm) kilograms (kg)
- Do wind turbines produce a constant supply of electricity?
- Like all substances, gases are made up of moving particles. The diagrams below show two pure samples of gas in identical closed containers. The colored balls represent the particles in each sample. square complete The mass of each particle is the same The particles in sample B have a lower average speed than the particles in sample A. Which particles have the lower average kinetic energy? the particles in sample A the particles in sample B nelther; the average kinetic energy is the same
- Savanna drew a diagram to show how radio waves are modified for use in the field of broadcasting. Cell Phone Carrier wave Data signal Which best describes Savanna's error? The label at the top of the diagram should be " F Radio," not "Cell Phone." The FM carrier waves should have different frequencies than the carrier waves, not different amplitudes. The carrier wave should be on the right of the modulator, not on the left of the modulator. The modulator should be labeled "Amplitude modulator," not "Enegquency modulator."
- A circuit consists of three resistors wired in series with a battery of constant voltage. The values of the resistors are: R_(1)=20Ohms;R_(2)=40Ohms;R_(3)=60Ohms The current through R_(1) is l_(1), and the current through R_(2) is I_(2) and the current through Ro Which of these options appropriately ranks currents? and the current through R_(3) I_(1)=2I_(2)=3I_(3) We cannot tell because we need the Voltage of the battery. I_(1)=0.5I_(2)=0.33I_(3) I_(1)=I_(2)=I_(3)
