Answer:

Two types of technology and the energy transformation that occurs within those types of technology that make them work is described below in detail.

Explanation:

A drone, in technological courses, is an unmanned aircraft. ... Typically, a drone is a hovering automaton that can be remotely commanded or cruise autonomously through software-managed flight systems in their installed systems, working in combination with onboard sensors and GPS.

Laptops consolidate all the input/output parts and abilities of a desktop processor, including the presentation screen, tiny speakers, a keyboard, a data storehouse device, sometimes an optical disc drive, aiming devices, with a running system, a processor, and memory into a particular unit.

1. A gas has a volume of 45 L at a pressure of 140 kPa. What is the volume when

pishuonlain [190]

Answer:

The new volume of the gas is 21 L.

Explanation:

Volume of a gas is inversely proportional to its pressure at constant temperature such that,

$V\propto \dfrac{1}{P}$

$P_1V_1=P_2V_2$

We have,

$V_1=45\ L\\\\P_1=140\ kPa \\\\P_2=300\ kPa$

It is required to find V₂. Using above law or Boyle's law such that :

$V_2=\dfrac{P_1V_1}{P_2}\\\\V_2=\dfrac{140\times 45}{300}\\\\V_2=21\ L$

So, the new volume of the gas is 21 L.

At constant temperature and pressure, 5.0 L of SO2 is

Ne4ueva [31]

I've done this a few times and keep coming up with 5.0 L . I used the mole ratio, and SO 2 as the LR. That would make 2 moles of SO3 5.0 L but its not one of your choices. the temp and pressure are constant, so according to n/v = p/rt the volume is the same as the moles. hope this helps

When a plant is entering the Calvin cycle of photosynthesis_____.

Andrei [34K]

B). light energy is not required to proceed

Explanation:

In the Calvin cycle of photosynthesis, light energy is not required. The Calvin cycle is light independent and it is made up of a series of redox reactions.

During photosynthesis reactions, green plants manufacture their food using carbon dioxide, sunlight and water.
During the Calvin cycle aspect, light energy is not required for chemical reactions to take place. The light energy helps to move electrons.
The cycle is also known as dark reactions.
It is at this stage that carbon dioxide combines with water to form glucose.
The reaction is initiated with light energy which produces NADPH and ATP.
The Calvin cycle follows by using the NADPH and ATP to produce glucose in the dark phase.
