A graph shows distance on the vertical axis and time on the horizontal axis. If the speed is steadily increasing, what will the line representing speed look like on the graph?
can you help me fill in the blank _______ waves are used to penetrate solids and are used in doctors offices and as airports
Imagine two artificial satellites orbiting earth at the same distance. one satellite has a greater mass then the other one which of the following would be true about there motion? 1. the satellite with the greater mass is being pulled toward earth with less of a force than the other satellite 2. the satellite with the greater mass is being pulled toward earth with greater force than the other satellite 3. the two satellites are being pulled with a equal force by the moon 4. the two satellites are being pulled toward earth with equal force
When a speeding truck hits a stationary car, the car is deformed and heat is generated. What can you say about the kinetic energy of the system after the collision?
Calculate the maximum kinetic energy of photoelectrons emitted from this plate when light of wavelength (λ) 520nm is directed at the metal surface. Work function (Ф) of the plate = 1.1 × 10⁻¹⁹ J Planck's constant (h) = 6.63 × 10⁻³⁴ Js Frequency (f) = c ÷ λ c = speed light in vacuum = 3.00 × 10⁸ms⁻¹ Ekmax = hf - Φ Wavelength must be in metres, so it'll be 590×10⁻⁹ I've worked this out and gotten two different answers so I thought I'd check to see which one is right.
