A student wraps the same beaker in two different insulating materials and measures the time for temperature to fall. If Material X takes 450 s and Material Y takes 745 s for the same drop, which statement is correct?
Which energy transfer occurs inside an incandescent lamp (filament) when it is switched on?
An ice block of mass 0.25 kg melts when 50 000 J are transferred to it. What is the specific latent heat of fusion inferred from this experiment?
Which equation gives the change in gravitational potential energy when an object of mass m is raised by height h in a gravitational field g?
Which formula links power (P), potential difference (V) and current (I) in an electrical circuit?
A 2.0 kg mass is raised 5.0 m in g = 9.8 N/kg. What is the increase in its gravitational potential energy?
A 0.50 kg block of metal is heated and its temperature rises by 20 °C. If c = 420 J/kg°C, how much energy is required?
A 60 kg person climbs stairs of height 1.75 m in 1.40 s. (g = 9.8 N/kg). What is their mechanical power output (rounded)?
A device takes 1000 J in and delivers 700 J of useful energy. What is its efficiency?
Why do well-insulated homes reduce overall energy consumption?
Which equation gives the electrical energy transferred E when a charge Q moves through a potential difference V?
