A policeman investigating an accident measures the skid marks left by a car on the horizontal road. He determines that the dista
sleet_krkn [62]
<h2>The velocity of car was m m/s </h2>

Explanation:

When the car skids , its centripetal force is provided by frictional force .

Here centripetal force F = \frac{mv^2}{r}

here v is the velocity of car and r is the radius of the curve .

The frictional force f = μ R

here μ is the coefficient of kinetic friction and R is normal reaction

Thus f =  m g

On horizontal road R = mg

Thus F = f  at the time of skid .

Thus v = \sqrt{\mu rg}

= \sqrt{0.29x23.74x10} = 9 m/s

A particular solid is an excellent conductor of thermal energy. Is it more likely to be a metal or a non-metal?
tensa zangetsu [6.8K]
It is more likely to be a metal. This is because metals are good heat conductors whereas non metals tend to be poor heat conductors.

Why is thermal energy from the Sun transferred to Earth through electromagnetic waves instead of any other type of thermal energ
Pachacha [2.7K]

Answer:

Electromagnetic waves can travel through empty space.

Explanation:

Electromagnetic waves are defined as the waves that are created due to the vibrations between a magnetic field and an electric field.

Earth atmosphere is made up of several gases and spaces between them. Thermal energy from the sun require to pass through space by electromagnetic radiation. Electromagnetic waves can travel through empty space and that is why other type of waves are unable to transfer thermal energy.

Hence, the correct answer is "Electromagnetic waves can travel through empty space".
