Ehh, Earth rotates around its axis and Earth revolves around the sun as it travels through space.
Answer: Option (d) is the correct answer.
Explanation:
Physical change is defined as a change in which no new product is formed, that is, there is no change in chemical composition of a substance.
For example, when ice melt then solid state of water changes into liquid state.
That is, arrangement of atoms changes and bond between the atoms do no break during a physical change.
Thus, we can conclude that the property bonds between atoms do not break; it is only the arrangement that changes explains why matter is conserved in a physical change.
The crystal of potassium chloride has a definite shape because it consists of particles that are held in fixed positions.
Ionic solids are crystalline in nature. This means that the ions that compose them are arranged in an orderly manner to form a crystal lattice.
This crystal lattice is composed of a regular repeating pattern called the unit cell. The ions in these unit cells are held together by strong electrostatic forces.
Hence, the crystal of potassium chloride has a definite shape because it consists of particles that are held in fixed positions.

Answer:
RT = 17 ohms
Explanation:
For two parallel resistances in a circuit the combined resistance is given by:

R1 = 25 ohms
R2 = 50 ohms
You replace the values of R1 and R2 in the formula for RT:

hence, the combined resitances is 17 ohms
The genotype<span> is the set of genes in our DNA which is responsible for a particular trait. The </span>phenotype<span> is the physical expression, or characteristics, of that trait. For example, two organisms that have even the minutest difference in their genes are said to have different </span>genotypes<span>.</span>
