Answer:
1. Periods; that are what horizontal rows on a periodic table are called.
2. Each period represents the number of levels
Explanation:
Power in physics is the rate of energy transferred per unit time. It can be calculated by dividing the amount of energy transferred by the time required for the transfer.
In Physics, power is defined as the rate of transferring energy or the amount of energy per unit time. If you want to calculate the power, you take the amount of energy transferred and divide it by the time it takes for that transfer to occur. For example, if a light bulb transfers 100 joules of energy over 10 seconds, the power would be 100 joules divided by 10 seconds, which equals to 10 watts.

spring
B.
summer
C.
fall
D.
winter
(this is science)
Answer: B. summer
Explanation:
Seasons occur due to tilt of the Earth. Earth's axis is tilted 23.5° from the vertical. As the Earth revolves around the Sun, sometimes the Northern hemisphere points towards the Sun and sometimes away.
When the northern hemisphere points towards the Sun, Summer occurs and in the Southern hemisphere, winter occurs. In Summers, the Sun is highest in the sky and the sun rays fall directly. The duration of day time is greatest in summers. In winters, the Sun is lowest in the sky and sun rays fall obliquely.
current in the flashlight?
Answer:
3 A
Explanation:
The relationship between voltage, current and resistance in a conductor is expressed by Ohm's law, which states that:
where:
V is the potential difference across the conductor
R is the resistance of the conductor
I is the current flowing through it
In this problem, for this flashlight we have:
V = 90 V is the potential difference
is the resistance of the flashlight
Solving for I, we find the current:
Elementary knowledge is essential and specialised. This level teaches fundamental concepts in numerous subjects.
"Elementary" or "fundamental" knowledge contains the most particular notions. This understanding creates the foundation for more complicated thoughts and numerous fields of study.
Elementary knowledge in science, mathematics, and other fields includes foundational ideas, definitions, and concepts needed to understand more complex topics. Such as:
Elementary mathematics includes basic arithmetic, number characteristics, and geometric shapes.
Elementary physics contains Newton's laws and thermodynamics.
Grammar, sentence structure, and vocabulary are elementary in language and literature.
Programming and data structures are computer science basics.
Elementary biology covers cell structure and function.
This foundational information is essential for understanding and interpreting more sophisticated ideas and theories in numerous topics. It supports field-specific learning and exploration. As a person masters basic knowledge, they can go on to more complex topics in their field.
