Describe the motion of the object in Graph B of figure 11-2.
kupik [55]

Answer : The motion of the object is, non-uniform

Explanation :

Uniform motion : It is defined as the movement of an object along a straight line with constant speed.  It travels equal distances in equal time interval.

The average speed of an object is similar to the actual speed of an object.  The distance-time graph shows a straight line.

Non-uniform motion : It is defined as the movement of an object along a straight line with variable speed.  It travels unequal distances in equal time interval.

The average speed of an object is different to the actual speed of an object.  The distance-time graph shows a curved line.

The given graph B is a non-uniform motion graph.

Hence, the motion of the object is, non-uniform

Daughter element the new element produced along with a decay particle in a nuclear transmutation 2. half-life the substance that
valentinak56 [21]

Answer:

1.  Daughter element : the new element produced along with a decay particle in a nuclear transmutation

2. half life: the time required for the decay of one-half of the atoms in a sample of radioactive material

3. parent element : the substance that decays in a nuclear transmutation

4.  transmutation :  the change of one chemical element into another by nuclear decay or radioactive bombardment

Explanation: Radioactive decay process is a type of process in which a less stable nuclei also called as parent element decomposes to a stable nuclei or a daughter element by releasing some radiations or particles like alpha, beta particles or gamma-radiations and the process by which one element changes to another element is called as transmutation.

_A^Z\textrm{X}\rightarrow _{A-2}^{Z-4}+_2^4\alpha

Half life is the time taken by an element to decay to half of its initial value.

When sugar or another substance is dissolved in water, it disappears from view and forms a homogeneous mixture with the water, a
adoni [48]
You can tell if the sugar is still there by boiling off the water and leaving the sugar behind in the container. Sugar is a solid, and therefore cannot evaporate, so when the water reaches boiling point, it will evaporate at a quicker rate than before (water evaporates at any temperature in liquid form; just not enough to be noticeable) and leave the container to become water vapour

Which type of rock would form from a lava following a volcanic eruption
melisa1 [442]

When lava reaches the surface of the Earth through volcanoes or through great fissures the rocks that are formed from the lava cooling and hardening are called extrusive igneous rocks. Some of the more common types of extrusive igneous rocks are lava rocks, cinders, pumice, obsidian , and volcanic ash and dust.
