A road that rises 1 ft for every 100 ft traveled

Physics
1 answer:
Lana71 [14]3 years ago
6 0

Explanation:

6% grade

=> Rises 6 feet for every 100 feet traveled

This would mean that tanx = 6/100.

=> x = tan^-1(6/100) = 3.4°. (1d.p.)

Hence the road is inclined at an angle of 3.4° above the horizontal.

An aluminum bar has a mass of 9 kg in the air. Calculate its volume. Now imagine that you submerge the aluminum bar in water han
yan [13]

Answer:

55.7 N

Explanation:

The density of aluminum is 2710 kg/m³.  So its volume is:

V = (9 kg) / (2710 kg/m³)

V = 0.00332 m³

The apparent weight is the actual weight minus the buoyant force.

N = mg − B

N = mg − ρVg

N = g (m − ρV)

N = (9.8 m/s²) (9 kg − (1000 kg/m³) (0.0332 m³))

N = 55.7 N

Lemon trees receiving the most water produced the most lemons. What is the independent variable, the dependent variable, and the
Veseljchak [2.6K]
The lemon trees will always be the same so they are the constants. The independent variable is the water amount because it is changing. The dependent variable is the amount of lemons because it is the variable being tested. (If we change the amount of water how many lemons will be produced?)

Arada [10]

Elements and compounds

Explanation:

  • All pure substances are distinct substances.
  • All their parts are the same throughout i.e they are homogeneous.
  • They have a definite composition.
  • They cannot be easily separated or broken down into simpler substances by physical means.
  • They have a unique set of physical properties.

Elements are distinct substances that cannot be split up into simpler ones.

Compounds are substances composed of two or more kinds of atoms joined together in a definite grouping.

a student standing in an elevator at rest notices that her pendulum has a frequency of oscillation of 0.5 Hz. a. what is the len
EastWind [94]

Answer:

L = 0.99 m = 99 cm

Explanation:

The period is the reciprocal of the frequency.

T = 1/0.5 = 2.0 s

T = 2π√(L/g)

L = g(T/2π)²

L = 9.8(2.0/2π)² = 0.99 m

If the system accelerates upward, it will cause the apparent gravity to increase. This will require a longer pendulum to keep the same period, or shorten the period if the length remains the same. This shows up in the equation where the product of gravity and the square of the period must remain constant for the length to remain constant.

alexandr402 [8]

Answer:

6.5646\times 10^{16}~ \text{Hz}

Explanation:

\text{Frequency,}~ f= \dfrac{c}{\lambda} = \dfrac{3\times 10^8 }{4.57 \times 10^{-9}} = 6.5646\times 10^{16}~ \text{Hz}
