The water molecules would slow down, and as they slow down, the heat created from their movement would cease.

The boiling point of water is 91.30 °C on the

Taya2010 [7]

Answer:

196.34 °F

Explanation:

To convert from degrees celsius to degrees fahrenheit, use this equation:

(°C * 9/5) + 32 = °F

So, using this equation:

(91.30 * 9/5) + 32 = °F

196.34 + 32 = °F

°F = 196.34

Hope this helps!

A common misconception is that an object always moves when a force acts on it. Why is this statement incorrect? Explain the conc

dsp73

Answer:

The statement is incorrect because, a force acting on an object does not necessarily have to produce motion.

People have the misconception that when a force acts on an object it always produces motion

Explanation:

The statement is incorrect because, a force acting on an object does not necessarily have to produce motion. It could be in static equilibrium where the net force is zero and produces not motion. The body could also be in dynamic equilibrium when no net force acts on it moving at a constant velocity. But here we are concerned with static equilibrium since the body does not move at all.

People have the misconception that when a force acts on an object it always produces motion and, we have seen from the above tat its not always true.

Discuss the differences between Seismic Reflection and Seismic Refraction

Maru [420]

Explanation:

Seismic refraction is the bending of the seismic waves as they pass geological layers of the earth due to different densities. This is especially true for Primary waves because they can pass through all the layers of the earth both liquid and solid.

Seismic reflectivity is the bouncing back of seismic waves at a boundary of geological layers due to different densities or subsurface formation. This is especially true for secondary waves that are unable to pass through liquid layers of the earth like the outer core and mantle. When they reach the boundary of these layers they bounce back towards the earth's surface.

These properties of P and S waves are used to ‘auscultate’ the epicenter of an earthquake by triangulation.

You’ve set up a frictionless car racetrack, with a loop of radius 0.5 m. Your toy car of mass 2 kg starts at rest at the top of

Anna007 [38]

Answer

h = 1.12 m

Explanation:

given,

mass of the car = 2 kg

radius = 0.5 m

let h be the height of the ramp

when the car reaches at the top point

gravity = centripetal force

$mg =\dfrac{mv^2}{r}$

$g =\dfrac{v^2}{r}$

$v = \sqrt{gr}$

using conservation of energy

$\PE_i = PE_f + KE_f$

$m g h = m g (2r)+\dfrac{1}{2}mv^2$

$g h =g (2r)+\dfrac{1}{2}(\sqrt{gr})^2$

$g h =2 gr +\dfrac{gr}{2}$

$h =\dfrac{5r}{2}$

$h =\dfrac{5\times 0.5}{2}$

h = 1.12 m

hence, height of the ramp should be greater than 1.12 m so that it can complete the loop.
