Answer and explanation;

-The cause of convention currents in a hot spring is rainwater and melted snow is cool and denser and sinks to the bottom of the hot spring where it is heated by a shallow magma chamber. The heated water expands and is less dense and rises to the top.

Explanation;

-Convention Current is the movement of fluid caused by the differences in temperature. Transference of heat from one part of a fluid to another.

-Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth. In the atmosphere, as air warms it rises, allowing cooler air to flow in underneath.

Why does Gravity have a lesser than grater effect on higher altitudes?

IrinaVladis [17]

The strength of the gravitational force between two objects depends on the distance between their centers.

At higher altitude, the center of the Earth is farther from the center of YOU, so the strength of the gravitational force between those two objects is less.

Newton’s second law relates an object’s acceleration to its mass and the net force acting on it. Does newton’s second law apply

alexgriva [62]

No, newton’s second law does not apply to a situation in which there is no net force.

<h3>What is force?</h3>

A force is a push or pull upon an object which stops or tends to stop the object and move or tends to move an object.

No, newton’s second law apply to a situation in which there is no net force because force compels the object to move in the direction in which force is applied so we can conclude that force is compulsory to move an object.

||||| A ball on a porch rolls 60 cm to the porch’s edge, drops 40 cm, continues rolling on the grass, and eventually stops 80 cm

3241004551 [841]

Answer:

$d = 145.6 cm$

Explanation:

first ball rolls on the porch by total distance

$x_1 = 60 cm$

Then again it will move on horizontal floor

$x_2 = 80 cm$

also in vertical direction it will drop down

$y = 40 cm$

so we have

$x = 60 + 80$

$x = 140 cm$

$y = 40 cm$

so magnitude of net displacement of the ball is given as

$d = \sqrt{140^2 + 40^2}$

$d = 145.6 cm$

scientific endeavor should only be pursued after known tradeoffs associated with the research have been considered. True or Fals

AfilCa [17]

This is false. There were many times in history when people discovered something that they didn't even know was possible or didn't even plan to discover it. Knowing tradeoffs doesn't mean that something won't surprise you or that all will go according to plan.
