Answer:
0.3 A
Explanation:
Build the circuit attached. Make sure the switch is turned off as you build the circuit. Set the Selected battery voltage to 10 volts.
A. Based on the number on the fuse, what do you think is the maximum current allowed in this circuit?
Solution:
A fuse is a safety device which is used in circuits for preventing very high currents which can cause overloading or start a fire. A fuse is made up of a low resistance thin piece of metal such that the flow of high current can cause the metal to melt leading to an open circuit. A fuse lets current flow up to a maximum value before it melts and the circuit will be broken.
From the image attached, since the maximum rating of the fuse is 0.3 A, hence the maximum current that can flow through the circuit is 0.3 A.
Answer:
solar energy warms most of the earths surface
Answer:
It is the force that is present because of the mass of our planet. it's what keeps us stuck on the surface of Earth rather than floating off into space.
Answer:
9 kg
Explanation:
According to Newton's second law:
Given:
f = 18 N
a = 2 m/s^2
Substitute the given values in the formula.
Answer:
In order to determine or find out about the age of archaeological finds such as fossils, rocks, etc., archaeologists use radioactive isotopes in a process called radioactive dating.
In agriculture, radioactive isotopes have a lot of uses. These comprise of but are not limited to the following:
- Improvement of food crops
- preservation of food,
- Establish and estimate the presence and volume of water in the soil for farms;
- Hormonal analysis for animals (livestock) etc
Explanation:
C-14 and Phosphorus - 32 are examples of Radioactive isotopes. Because they decay over time, they are easy to use when it comes to radioactive dating.
When an isotope carried an unstable amount or number of atoms, neutrons, and protons, they are said to be Radioactive. It also means that they have too unstable or excess energy in their nucleus. This condition causes them to decay faster than their stable relatives.
In archaeology, dating the artifacts that are discovered is important because it helps to establish the correct relationship between one find or artifact and another. Because humans can't go back in time, one of the ways to know what humans did or didn't do, or what events occurred in a place by other living things is the items/evidence they left behind. Categorizing these times/artifacts by date helps to give a clearer picture of what happened in a particular block of time and this is exactly what dating is all about.
In agriculture, one of the radioactive isotopes used is Phosphorus - 32.
When the plant's uptake of fertilizer from the roots to the leaves needs to be established, Phosphorus-32 is utilized. A fertilizer that has already been mixed with the above radioactive isotope is administered to the plant using a hydroponic system or via the traditional means (water in the soil). The phosphorus 32 emits beta radiation which is then tracked and mapped accordingly.
