Answer:
operates om the principle of temperature-induced resistance.
Explanation:
In physical quantities, the resistance of an electrical conductor can be correlated directly with the temperature of the material. The property for the change in the resistance with temperature is called the temperature coefficient of resistance. Mathematically, the resistance of a material is given as follows:
![R = R_{ref} [ 1 + \alpha (T - T_{ref})]](https://tex.z-dn.net/?f=R%20%3D%20R_%7Bref%7D%20%5B%201%20%2B%20%5Calpha%20%28T%20-%20T_%7Bref%7D%29%5D)
where R = conductor resistance at the temperature T.
Rreff = the conductor resistance at the reference temperature,
= temperature coefficient of resistance
T = Conductor temperature
Treff = reference temperature of the material.
From the equation, it can be seen that a positive coefficient for a material means an increase in the resistance of the material.
Answer:
4
Explanation:
According to Mendel's law of purity of gametes, each gamete contains single allele for a gene. The alleles of a gene segregate during gamete formation and each gamete has one allele for a gene irrespective of the total number of alleles for a gene.
If the gene for skin color in a fish species has four alleles, an individuals fish would have only two alleles which in turn would segregate during gamete formation.
Since there are four different alleles of the gene (let's assume a,b,c, and d), total possible gametes produced by this organism will be = 4. A gamete can have one of the total 4 alleles making total 4 types of the gametes each with a or b or c or d allele.
This is potential energy because while he was aiming at a bull's eye target, he is storing energy
Answer:
Explanation:
The test tube that first stops in bubbling or the production of a gas is the tube that contains the catalyst since the reaction ended faster than the others. A catalyst is known to speed up a reaction so it must the situation aforementioned is the answer.
