If you put a penny in each light spot the penny that the light is shining on will recive the most energy.
Use the eq. of Young modulus Y=(F/A)/(∆l/lo)
dimana ∆l is the elongation of wire, lo is its initial length.
So ∆l = (F/A)lo/Y.
∆l = (1000N/(6.5 × 10^-7 m^2))×(2.5m)/(2.0 × 10^-11 N/m^2)
Use calculator to finish it.
Answer:
The speed of the vehicle was 21 m/s
Explanation:
Momentum can be defined as mass in motion
Momentum depends on the variables mass and velocity
The momentum of an object is equal to the mass of the object times the
velocity of the object
The given is:
→ A Jeep Rubicon has a mass of 2,630 kg
→ With a momentum of 55,200 kg m/s
We need to find the speed of the vehicle
→ The momentum = mass × speed
Substitute the values above in the rule
→ 55,200 = 2,630 × speed
Divide both sides by 2,630
→ speed = 20.99 ≅ 21 m/s
<em>The speed of the vehicle was 21 m/s</em>
The correct answer is:
<span>B) orange, yellow, green, blue
the energy of the photons of light is directly proportional to the frequency of the light. This means that the lower the frequency, the lower the energy, and the higher the frequency, the greater the energy.
Therefore, the order in increasing energy is exactly the same as the order in increasing frequency, which is:

orange, yellow, green, blue </span>
