Homeostasis: the ability to keep a system at a constant condition. Hormone: a chemical message released in the body by cells and glands that affects other cells in an organism. Hypothalamus: a part of the brain that controls things like thirst, hunger, body temperature, and the release of many hormones.

A car is moving at a velocity of 25 km/h and increases velocity to 1200 km/h in 2 min. what is the acceleration?

OlgaM077 [116]

Answer:

a = 2.72 [m/s2]

Explanation:

To solve this problem we must use the following kinematics equation:

$v_{f} =v_{o} + a*t$

where:

Vf = final velocity = 1200 [km/h]

Vo = initial velocity = 25 [km/h]

t = time = 2 [min] = 2/60 = 0.0333 [h]

1200 = 25 + (a*0.0333)

a = 35250.35 [km/h2]

if we convert these units to units of meters per second squared

$35250.35[\frac{km}{h^{2} }]*(\frac{1}{3600^{2} })*[\frac{h^{2} }{s^{2} } ]*(\frac{1000}{1} )*[\frac{m}{km} ] = 2.72 [\frac{m}{s^{2} } ]$

Which 90% of your brain would you like to remove while driving a car? Explain/defend your answer.

Hatshy [7]

The human beings use 10 % of the brain and the remaining 90 percent is full of unused potential and undiscovered abilities.

Explanation:

It is stated that every human beings use 10 percent of their brain and the other 90 percent is used only for operating a limited stretch. the average adult human brain can store the 2.5 million gigabytes digital memory.

The human brains contains about 100 billion neurons and around i quadrillion to 1 million connections in the cells. The dendrites provide more information than passive wiring.

The unused part of the brain is not necessary it simply occupies the space. The damaged parts of the brain should be removed.

How did the current change when the circuit was initially closed in Part 2 of this exercise? Explain your answer by referencing

Radda [10]

Answer:

Some current is lost.

Explanation:

Change occur in the current when the circuit was initially closed because in a closed circuit the current moves from the start towards the end of the circuit through various resistors. There is heat produced in the wire when the current flows through the circuit. Due to this heat, some of the current is lost during on his own way. Capacitor is a device used to store an electric charge, having of one or more pairs of conductors separated by an insulator. while on the other hand, electric current is a stream of charged particles, such as electrons moving through conductor or space.

Determine the repeat distance, linear density, and packing fraction for BCC lithium, which has a lattice parameter of 0.35089 nm

NeX [460]

Answer:

The [111] direction is close packed; the linear packing factor is 1.

Explanation:

Lattice parameter = a₀ = 0.35089nm

Directions 100, 110 and 111

r = 3a₀

where r = repeat distance

r = 3(0.35089)

r = 0.1519nm

For [100]; r = a₀ = 0.35089nm

Linear density = 1/a₀ = 2.85points/nm

linear density = 1/a₀ = 2.85 points/nm

linear packing fraction = (2)(0.1519)(2.85) = 0.866

For [110]; r = 2a₀ = 0.496 nm

linear density = 1/a₀ = 2.015 points/nm

linear packing fraction = (2)(0.1519)(2.015) = 0.612

For [111]: r = 3a₀/2 = 0.3039 nm

linear density= 2/3a₀ = 3.291 points/nm

linear packing fraction = (2)(0.1519)(3.291) = 1

Therefore, from the above, [111] direction is close packed; the linear packing factor is 1.

Answer:

The images show two different types of Galapagos tortoises that scientists believe descended from the same species. The first type (left) are found on islands that have high vegetation and few grasses. The second type (right) are found on an island that has large amounts of grasses and low-lying shrubs. What explains the type of turtle found on the islands with high vegetation?
