Answer:75 percent
Explanation:so in order tro fin d thge efficiency i used the forumla ,efficency=useful output energy/input energyx100%,in order to use this formula i needed the output,which i found by subtracting the input energy with wasted energy,that gave me the output,and after founding the output,i put that into the formula,
output energy=input energy - wasted energy
output energy=6000j-1500j
output energy=4500
put that into the formula
efficiency =output energy/input enrgy x100%
efficiency=4500/6000 multiplied by 100%
efficiency=0.75x100%
efficiency=75%
The wavelength is the spatial period of a periodic wave—the distance over which the wave's shape repeats.
The basic monomer of a lipid is a triglyceride. It breaks down into one glycerol molecule and 3 fatty acid tails.
Answer:
Explanation:
We shall apply the formula of Doppler effect here
F( APPARENT) = F( REAL ) X V/(V + Vs) [ v is velocity of sound and Vs is velocity of source.
415 = 440 X 343/343+Vs
142345 + 415Vs = 150920
415 V₀ = 8575
V₀ = 20.66 m/s.
Answer:
Newtons First Law (The Law of Inertia)- If an object is at rest it will stay at rest until a net force acts on it. If an object is in motion it will stay in motion until a net force acts on it.
Newtons Second Law (F=ma)- Force equals the mass of an object times it's acceleration.
Newton's Third Law- For every action there is an equal and opposite reaction.
hope this helps!
