Answer:

Friction does not depend on the amount of surface area in contact between the moving bodies or (within certain limits) on the relative speed of the bodies. It does, however, depend on the magnitude of the forces holding the bodies together.

Mathematically, the Mofo dam has a depth of 60 feet of water, and Fus-Ro-Dah Dam has a depth of 50 feet of water.

Hence, the Mofo dam is constructed to be the strongest.

Question Parameters:

The Mofo Dam holds back a depth of 60 feet of water

The Fus-Ro-Dah Dam holds back a depth of 50 feet of water,

the lake behind the dam is 2 miles wide.

Generally, The main independent factor to be considered is the depth of a dam, as its the depth of water that applies the most pressure on dams, So the only effective factor is depth.

In conclusion, the Mofo dam because it holds back a depth of 60 feet of water, While the Fus-Ro-Dah Dam holds back a depth of 50 feet of water,

Answer:

The smooth surface of the CD causes wavelengths of light to scatter. The CD at this point acts somewhat like a prism splitting white light into the colors of the rainbow. This is called the visible spectrum of light and is composed of the colors red, orange, yellow, green, blue, indigo and violet.

Explanation:

Answer: The reflected wave has less energy

Explanation:

The incident wave would be the light wave before it comes in contact with the CD. Once the incident wave hits the CD, there is a reflected wave which will have some portion of energy from the incident wave. The reflected wave is a different color from the incident wave due to the reflected wave having less energy. Less energy means a different wavelength of visible light

Answer:

500kJ

Explanation:

Common equation;

GPE = mgh

m = mass - in kg

g = gravitational field strength - in N/kg

h = height lifted/lowered - in meters

GPE = 10kg × 10N/kg × 5000m

GPE = 500000Nm

GPE = 500000J

GPE = 500kJ

Answer:9,750,000,000

Explanation:

975kg can be recovered so 975x10,000,000

The total mass of magnetic metals that could be recovered from scrapped cars each year will be equal to 9750,000,000.

The four basic mathematical operations are the addition, subtraction, multiplication, and division of two or even more integers. Among them is the examination of integers, particularly the order of actions, which is crucial for all other mathematical topics, including algebra, data organization, and geometry.

As per the provided given data in the question,

Ten million cars are scrapped each year, then the total mass of magnetic material that could be recovered,

975kg can be recovered so,

= 975 × 10,000,000

= 9750,000,000

Therefore, it is concluded that the metal that could be recovered from scrapped cars each year will be equal to 9750,000,000.

The new frequency of oscillation when the car bounces on its springs is 0.447 Hz

The frequency of oscillation of the spring is given by f = (1/2π)√(k/m) where

Now since k is constant, and f ∝ 1/√m.

So, we have f₂/f₁ = √(m₁/m₂) where

So, making f₂ subject of the formula, we have

f₂ = [√(m₁/m₂)]f₁

Substituting the values of the variables into the equation, we have

f₂ = [√(m₁/m₂)]f₁

f₂ = [√(m₁/5m₁)]1.0 Hz

f₂ = [√(1/5)]1.0 Hz

f₂ = 1.0 Hz/√5

f₂ = 1.0 Hz/2.236

f₂ = 0.447 Hz

So, the new frequency of oscillation when the car bounces on its springs is 0.447 Hz

(a) The energy lost to friction by the skateboarder is -699.6 J.

(b) The maximum height above the bottom of the ramp is 1.3 m.

The energy lost to friction by the skateboarder is calculated from the change in kinetic energy of the skateboarder.

ΔK.E = K.Ef - K.Ei

ΔK.E = ¹/₂m(vi² - vf²)

ΔK.E = 0.5 x 55 (4.1² - 6.5²)

ΔK.E = -699.6 J

The maximum height above the bottom of the ramp is determined from conservation of energy.

mghi + ¹/₂mvi² = ¹/₂mvf² + mghf

55 x 9.8 x hi  +  (0.5 x 55 x 6.5²) = (0.5 x 55 x 4.1²) + (55 x 9.8 x 0)

539hi + 1161.88 = 462.28

539hi =  -699.6

hi = -699.6/539

hi = -1.3 m

Thus, the maximum height above the bottom of the ramp is 1.3 m.
