Answer:
Gravity Increases - Mass increases, distance decreases
Gravity Decreaes - Mass decreases, distance increases
The law of superposition in sedimentary and extrusive igneous rocks states that an upper bed of rock is younger than a lower one, provided that earth-movements have not reversed the order. Radioactive dating is the use of radioactive elements to determine the age of different items. The premise of radioactive decay is dependent on the fact that unstable elements break down at a fixed rate into other elements. Hence the age of rocks containing radioactive elements can be determined.
Answer:
34.3Hz
Explanation:
We know that
For a pipe open at one end, fundamental frequency (Fo)
is
Fo = v/4L
Where v= 340m/s
Fo = 340/4 x 2.48 = 34.3Hz
From the law of conservation of momentum, the first egg did not break because it forward momentum is transferred to the cloth while the second egg broke, the block exerts an opposite force equal to the momentum of the egg on the egg.
<h3>Momentum</h3>
Momentum is the product of the mass of an object and its velocity of motion.
The law of conservation of momentum states that the momentum of an isolated system of colliding bodies is conserved.
When an egg is thrown on a large sheet of cloth suspended, the egg does not break because the momentum of the egg is transferred to the cloth as it is depressed.
However, a second egg, thrown with similar force at a suspended concrete block, did break on impact because the block does not move forward, instead it exerts an equal but opposite force on the egg resulting in the egg breaking.
Therefore, from the law of conservation of momentum, the first egg did not break because it forward momentum is transferred to the cloth while the second egg broke, the block exerts an opposite force equal to the momentum of the egg on the egg.
