Answer:
TOTAL ENERGY = 0.74 j
Explanation:
Given data:
spring constant is 350 N/m
m = 0.24 kg
b = 0.41 kg/s
A = 0.075 M
after one full cycle, mass will be at extreme point, hence K,E = 0
But total energy remain same
y after one full cycle is\
y = 0.06517 m
y = 6.517 cm
total energy 
Explanation:
Below is an attachment containing the solution.
Optical squares are simple sighting instruments used to set out right angles. They can be provided either with mirrors or with one or two prisms. Because of practical difficulties in using squares with mirrors, they have been replaced by squares with prisms: "prismatic squares".
1 liter = .264 gallon
1 km = .621 mile
this means that 58.3km/L is equal to 137.13mpg
so
500/137.13 = 3.65 gallons of gas
3.65 x 3.5 = $12.78
Answer:
b. spark plugs
Explanation:
Diesel engines are characterized in that the mechanism that activates the explosion of fuel is high pressures, so when the piston reaches the top of the cylinder, the pressure of the air-diessel mixture is so high that it causes the explosion, this It is what generates the power in a diesel engine.
