Convective cooling cools rocks much more rapidly than heat conduction. hydrothermal circulation represents convective cooling at

Luda [366]

When geophysicists measure the geothermal gradient in areas on the ridges where there is no activity hydrothermally, the gradient is far below than what is predicted theoretically, but when measured near hydrothermal vents it is more than what is predicted. This is because most of the heat is being carried through convection by hydrothermal systems so that the average gradient when measured far from the circulation would be depressed or lower.

A spring scale hung from the ceiling stretches by 6.1 cm when a 2.0 kg mass is hung from it. The 2.0 kg mass is removed and repl

Hunter-Best [27]

The ideal spring equation is

   Stretch = K times Force .

This says that the stretch is directly proportional to the force.
In simple English, that means that if you double the force, then
you double the stretch, and if you multiply the force by π or
any other number, you multiply the stretch by the same number.

So you can always write a proportion for a spring:

   Stretch₁ / Force₁ = Stretch₂ / Force₂ .

Part A:

In Part-A of this question, the force is increased to (2.5 / 2.0) = 1.25 times .

So the stretch is also increased to 1.25 times .

   (1.25) x (6.1 cm) = 7.625 cm .

A 50g ball is released from rest 1.0 above the bottom of thetrack

ludmilkaskok [199]

Answer:

The maximum height of the ball is 2 m.

Explanation:

Given that,

Mass of ball = 50 g

Height = 1.0 m

Angle = 30°

The equation is

$y=\dfrac{1}{4}x^2$

We need to calculate the velocity

Using conservation of energy

$\Delta U_{i}+\Delta K_{i}=\Delta K_{f}+\Delta U_{f}$

Here, ball at rest so initial kinetic energy is zero and at the bottom the potential energy is zero

$\Delta U_{i}=\Delta K_{f}$

Put the value into the formula

$mgh=\dfrac{1}{2}mv^2$

Put the value into the formula

$50\times10^{-3}\times9.8\times1.0=\dfrac{1}{2}\times50\times10^{-3}\times v^2$

$v^2=\dfrac{2\times50\times10^{-3}\times9.8\times1.0}{50\times10^{-3}}$

$v=\sqrt{19.6}$

$v=4.42\ m/s$

We need to calculate the maximum height of the ball

Using again conservation of energy

$\dfrac{1}{2}mv^2=mgh$

Here, h = y highest point

Put the value into the formula

$\dfrac{1}{2}\times50\times10^{-3}\times(4.42)^2=50\times10^{-3}\times9.8\times h$

$y=\dfrac{0.5\times(4.42)^2}{9.8}$

$y=0.996\ m$

Put the value of y in the given equation

$y=\dfrac{1}{4}x^2$

$x^2=4\times0.996$

$x=\sqrt{4\times0.996}$

$x=1.99\ m\ \approx 2 m$

Hence, The maximum height of the ball is 2 m.

A cylindrical solid has a diameter of 1.62cm and a height of 5.04 cm. If the mass of the object is 50.12 g, what is the density

zimovet [89]

Density of cylinder is 4.82 g/cm³.

<h3>What is density of a substance?</h3>

Density is the ratio of the mass and the volume of a substance

Density = mass/volume

The density of the cylinder is:

mass of cylinder = 50.12 g

volume of cylinder = πr²h

r = 1.62/2 = 0.81 cm

h = 5.04 cm

volume of cylinder = 22/7 * 0.81² * 5.04

volume of cylinder = 10.39 cm³

Density of cylinder = 50.12 g/10.39 mL

Density of cylinder = 4.82 g/cm³

In conclusion, density of a substance is the ratio of mass and volume of the substance.
