15)c)increase in temperature
It is correct
HEY FRIENDHERE IS UR ANSWER
Shape is the answer
HOPE IT HELPSPLS MARK IT AS BRAINLIEST!!!
Option C is Correct.
Because it don't have definite shape and it assume the shape of the vessels.
Fluid gets the shape of the container
hope it helps
no it's not true
basis city of an acid is a number of hydroxide ions can be produced by one molecule of an acid when diluted with water .
if sally breaks through the chain of arms, she's also demonstrated several key aspects to the space concept of escape velocity. escape velocity (or a rousing game of red rover) requires an object to propel itself with enough speed and thrust to break through a barrier. sally's reward is the cheers of her teammates. a spacecraft's reward is a journey into space or orbit.
escape velocity is the speed at an object must travel to break free of a planet or moon's gravitational force and enter orbit. a spacecraft leaving the surface of earth, for example, needs to be going about 11 kilometers (7 miles) per second, or over 40,000 kilometers per hour (25,000 miles per hour), to enter orbit.
an endless cycle
saturn v rocket being prepared for launch escape velocity is one of the biggest challenges facing space travel. the requires an enormous amount of fuel to break through earth's gravitational pull. all that fuel adds significant weight to the spacecraft, and when an object is heavier, it takes more thrust to lift it. to create more thrust, you need more fuel. it's a cycle that scientists are hoping to resolve by creating lighter , more efficient fuels and new methods of propulsion that don't require the same ingredients to attain great speeds.
