In a food web the energy is originated from the SUN.
Gamma rays are the highest energy EM radiation and typically have energies greater than 100 keV, frequencies greater than 1019 Hz, and wavelengths less than 10 picometers.
The 24-toothed gear will turn 4 times.
hope this helped!
Yeah I’m guessing because I need help also
Answer:
A) = 0.63 m
B)This is approximately 0.21
Explanation:
Part A)
Now if spring is connected to the block then again we can use energy conservation
so we will have
so we will have
so total distance moved upwards is
Part B
Now the incline has a coefficient of kinetic friction μk. If the block, attached to the spring, is observed to stop just as it reaches the spring's equilibrium position, what is the coefficient of friction μk
KE = 8.75 – 10.78 * sin 41
This is approximately 1.678 J. This is the kinetic energy at the equilibrium position. For the block to stop moving at this position, this must be equal to the work that is done by the friction force.
Ff = μ * 10.78 * cos 41
Work = 0.5 * μ * 10.71 * cos 41
μ * 10.78 * cos 41 = 8.75 – 10.78 * sin 41
μ = (10 – 8.82 * sin 41) ÷ 8.82 * cos 41
μ = 1.678/8.136
μ = 0.206
This is approximately 0.21
