Answer: if the mass is doubled, the force of gravity is doubled, meaning it decreases. If the distance is doubled, the force of gravity is 1/4 as strong as before
Explanation:
Neuroscientist mostly agreed that there is no agreed-on benchmark, that a brain is fully developed. However, it is safe to say that brain is continuing to developed well past at the age of "18". Brain development happen in different stages and all in varying times. Brain consist of gray matter and white matter. Gray matter grows as we learn, as puberty sets in, our brain starts to prune back some of the gray matter, and produces more white matter, to share information better and faster. Overall most neuroscientist agree that, there is no magic age at which the brain reaches adulthood, but about age 22 or 23, the brain is pretty much done developing.
Answer:
A voltage-controlled resistor (VCR) is a three-terminal active device with one input port and two output ports. The input-port voltage controls the value of the resistor between the output ports. VCRs are most often built with field-effect transistors (FETs). Two types of FETs are often used: the JFET and the MOSFET.

hope this helps :D
Answer:
0.51 m
Explanation:
Using the principle of conservation of energy, change in potential energy equals to the change in kinetic energy of the spring.
Kinetic energy, KE=½kx²
Where k is spring constant and x is the compression of spring
Potential energy, PE=mgh
Where g is acceleration due to gravity, h is height and m is mass
Equating KE=PE
mgh=½kx²
Making x the subject of formula
Substituting 9.81 m/s² for g, 1300 kg for m, 10m for h and 1000000 for k then
Answer:
Coccus is suitable for dry environment and a rod is better adapted for moist environment.
Explanation:
The probability of Coccus would be better suitable for a environment which is dry. A sphere posses less surface area for the volume, as such, moisture which is lost through osmosis is less in dry environment conditions.
During a moist environment, the ratio of the surface area to volume of a rod shaped bacterium is high, which allow higher efficiency to transfer water and solutes into and outside of the cell, and to make possible for a cell which is in rod shaped, have a metabolic rate higher.
