Answer:
In a series circuit, all components are connected end-to-end, forming a single path for current flow. In a parallel circuit, all components are connected across each other, forming exactly two sets of electrically common points.
Explanation:
The experimental procedure would provide evidence that plants need
nitrogen to grow is by
- Identical plants are placed in two air-tight containers with sufficient exposure to sunlight.
- One container has nitrogen gas, and the other has room air. The scientist measures plant growth
It is necessary to use identical plants during the experiment as plants have
different rates of nitrogen absorption from the soil. It should also be done in
air-tight containers called terrariums to prevent loss or contamination of the
gases with other elements/compounds.
The identical plants containing nitrogen and room air should both be
measured for the growth difference between them.

Answer:
1. Protons
2. Electrons
3. Neutrons
4. Protons and neutrons
5. Electrons
Explanation:
The protons are the only positive sub-atomic particles and the have a charge of +1.
The Electrons are the only negative subatomic particles and they have a charge of -1
Neutrons do not have any charge but they have the same mass as the protons
The nucleus of an atom is where most of the atomic masses are concentrated and it houses the neutrons and protons
The electrons reside outside the nucleus and they have a much more lesser mass compared to the neutrons and protons
Answer:
No because a straw is plastic look at it by this was, the energy used to create one metal straw is roughly equivalent to creating 90 plastic straws, and also produces carbon emissions equivalent to 150 plastic straws. This may not seem like a lot, but in order to offset the environmental impact of creating a metal straw, it must be used over 150 times
Explanation:
Hi! Well the formula of kinetic energy is Ke = 0.5 x M x V^2
0.5 x 0.5 x 10^2
0.25 x 20
5 J (joule)
