In a power station 900 MJ of thermal energy were released by burning natural gas. Only 405 MJ was generated. Calculate the efficiency of this energy transfer.

this is a good question! i'll do some research and come back when i have the answer!

c) up is the direction the magnetic force is acting on the charge.

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
