a cartesian diver is a classic science experiment which demonstrates the principle of buoyancy and the ideal gas law.
It says that the force of a spring is always opposite to the direction in which you stretch it or compress it. (the direction of 'x')
In other words, a spring that's disturbed always tries to put itself back to it's normal length, where x would be zero.
Answer:
there is no change because a physical change only changes the physical appearance of a substance
Explanation:
a chemical change is the only change that can change a substance since it changes the chemical properties of the substance, hence making a new substance
Answer:
h = 36.4 cm
Explanation:
given,
spring constant = 2.5 x 10⁴ N/m
compressed distance = 11.2 cm = 0.112 m
mass of the child = 44 kg
maximum height = ?
by energy of conservation
h = 0.364 m
h = 36.4 cm
In order to completely describe a velocity,
you need a speed and a direction.
