Answer:
Heat required = mass× latent heat Q = 0.15 × 871 ×
Answer:
tan is 15 for that triangle
Acceleration x time = velocity
Since you're given acceleration and time, just plug the values into the equation.
3

x 1.1 s = ?
Solve that equation, and remember your velocity should be in m/s.
R1 + R4 = 1430 + 1350 = 2780 = R14 series combination of R1 & R4
R2 + R5 = 1350 + 1150 = 2500 = R25
The circuit has been reduced to 3 resistors in parallel
R314 = 2780 * 1100 / (2780 + 1100) = 788 this is the resistance of the parallel combination of R14 and R3
R31425 = 2500 * 788 / (2500 + 788) = 599 which is the equivalent of the circuit - you can also use the formula for 3 resistors in parallel but this seems simpler
