Objects 1 and 2 attract each other with a electrostatic force of 72.0 units. If the charge of object 1 is doubled AND the charge
lbvjy [14]

Answer:

432 units

Explanation:

Let the charges be q and Q separated by a distance r. The electrostatic force , F = kqQ/r² = 72 units. If q = 2q and Q = 3Q, then the new electrostatic force is

F = k × 2q × 3Q/r² = 6kqQ/r² = 6 × 72 = 432 units

The theory of evolution is
tresset_1 [31]

one of several competing scientific models that all seem equally successful in explaining the nature of life on Earth

Explanation:

  • The theory of evolution is one of the several competing scientific models that all seems to successfully explain the nature of life on earth.
  • A theory is usually drawn from careful observation of scientific investigation.
  • Theories generally provides explanation into a phenomenon that occurs in nature.
  • They are products of careful scientific observations and experiments.
  • The theory of evolution is but one of them.

Approximate the skin friction drag on a 1m long by 60 cm diameter cylinder, located axially in a wind tunnel, when the air speed
TiliK225 [7]

Answer:

The drag force is 1.76\times10^{-2}\ N

Explanation:

Given that,

Diameter = 60 cm

Length = 1 m

Air speed = 4.5 m/s

Temperature = 50°C

We need to calculate the Reynolds number

Using formula of Reynolds number

R_{e}=\dfrac{vl}{\mu}

Put the value into the formula

R_{e}=\dfrac{4.5\times1}{1.900\times10^{-5}}

R_{e}=2.368\times10^{5}

We need to calculate the drag coefficient

Using formula of drag coefficient

C_{d}=\dfrac{2\times0.646}{\sqrt{R_{e}}}

Put the value into the formula

C_{d}=\dfrac{2\times0.646}{\sqrt{2.368\times10^{5}}}

C_{d}=0.002655

We need to calculate the drag force

Using formula of drag force

F_{d}=\dfrac{1}{2}\times C_{d}\times\rho\times A\times v^2

Put the value into the formula

F_{d}=\dfrac{1}{2}\times0.002655\times1.095\times0.6\times1\times(4.5)^2

F_{d}=0.01766\ N

F_{d}=1.76\times10^{-2}\ N

Hence, The drag force is 1.76\times10^{-2}\ N
