On a highway curve with a radius of 46 meters, the maximum force of static friction that can act on a 1,200 kg car going around

Mekhanik [1.2K]

Answer:

$v\approx 16.956\,\frac{m}{s}$

Explanation:

The motion of the vehicule on a highway curve can be modelled by the following equation of equilibrium:

$\Sigma F = f = m\cdot \frac{v^{2}}{R}$

The maximum speed is:

$v = \sqrt{\frac{f\cdot R}{m} }$

$v = \sqrt{\frac{(7500\,N)\cdot (46\,m)}{1200\,kg} }$

$v\approx 16.956\,\frac{m}{s}$

Conduction transfers Thermal energy by

Vesnalui [34]

Answer:

Conduction is the transfer of heat between substances that are in direct contact with each other. The better the conductor, the more rapidly heat will be transferred. Metal is a good conduction of heat. Conduction occurs when a substance is heated, particles will gain more energy, and vibrate more.

Liquid can flow but solid cannot give reason

Airida [17]

Answer:

well..

Explanation:

Liquid can flow but solid cannot because of differences in their properties

property of liquid which lets it flow:

inter-particular space is large
inter-particular attraction is small these properties tend to make the molecules of liquid free to flow

property of solid which tends to obstruct flow:

inter-particular space is small and so it's compact
inter-molecular attraction is strong hence no tendency to flow

Hope this helps!
