Here's a question from ~ [ AIEEE 2002 ]
lyudmila [28]
  • r=150m
  • coefficient of friction=\mu=0.6

As car is avoid skidding

\\ \sf\hookrightarrow \dfrac{mv^2}{r}=\mu mg

  • Cancel m

\\ \sf\hookrightarrow \dfrac{v^2}{r}=\mu g

\\ \sf\hookrightarrow v^2=\mu rg

\\ \sf\hookrightarrow v^2=0.6(10)(150)

\\ \sf\hookrightarrow v^2=60(150)

\\ \sf\hookrightarrow v^2=900

\\ \sf\hookrightarrow v=30ms^{-1}

Done

According to current scientific thinking how did the solar system that contains earth form
KiRa [710]
Scientists think the solar system formed around 4.6 billion years ago from a cloud of dust and gas known as a solar nebula. Gravity collapsed the material on itself as it began to spin. This formed the sun in the middle. The planets formed when rock joined together in clumps and became bigger and bigger. And thus, our solar system was formed. Hope this helped

You have a stopped pipe of adjustable length close to a taut 62.0-cm, 7.25-g wire under a tension of 3910 N . You want to adjust
Ber [7]

Answer:

L = 6 cm

Explanation:

Second overtone of the wire is same as third harmonic

so its frequency is given as

f = \frac{3}{2L}\sqrt{\frac{T}{\mu}}

here we know that

\mu = \frac{M}{L}

\mu = \frac{7.25 \times 10^{-3}}{0.62}

\mu = 0.0117 kg/m

now we have

f = \frac{3}{2\times 0.62}\sqrt{\frac{3910}{0.0117}}

f = 1398.6 Hz

Now fundamental frequency of sound in a pipe is given as

f = \frac{v}{4L}

1398.6 = \frac{340}{4L}

L = 0.06 m

L = 6 cm

What are scientific theories?
Goryan [66]

A scientific theory is an explanation of an aspect of the natural world that can be repeatedly tested and verified in accordance with the scientific method, using accepted protocols of observation, measurement, and evaluation of results. Where possible, theories are tested under controlled conditions in an experiment.
