Kaya collects the data shown in the table. What is the resistance in the circuit? 0.05 1.8 5.7 20
Answers
Kaya collects the data where the voltage is 6 V also the current is 0.3 A then the resistance in the circuit will be 20 ohms. Hence, option D is correct.
What is Electrical energy?
When put in an electromagnetic field, charged matter experiences a force due to the fundamental property of electric charge. Positive or negative electrical ions are possible. When two charges are in opposition to one another, they repel one another.
The term "neutral" refers to an object that has no net charge. The early understanding of the way charged particles interact is now referred to as classical electrodynamics, and it is still true for issues that do not demand taking into account quant phenomena.
As per the given information in the question,
Voltage, V = 6 V
Current, I = 0.3 A
Use the equation of ohm's law,
V = RI
6 V = R(0.3)
R = 6/0.3
R = 20 Ω.

Answer: The acceleration is 145.54 m/s^2
Explanation: The second Newton's law says that:
F = m*a
This says that the Force applied on an object is equal to the mass of the object times the acceleration of the object.
We know that the mass of the ball is 0.426kg and the force is 62N, so we have
62N = 0.426kg*a
a=62N/0.426kg= 145.54 m/s^2
62/.426=a
154.54= acceleration

Explanation:
As we know that there is no wind resistance on the skydiver
so when he jumps out of the helicopter then in that case the net force on the diver will be due to gravity only
so his equation for force is given by
now from the Newton's law of motion we will have
from the given options we will have
so the acceleration is
Initially, like any falling object, a skydiver's downward acceleration is 9.8 meters/seconds^2, or about 28-35 feet per second squared. This acceleration reduces over a few seconds and approaches zero as the skydiver reaches terminal velocity.

The phase is frequently used to describe transitions between the three fundamental states of matter. Condensation is the phase change in the atmosphere forms clouds.
What is phase transition?
The physical process of changing a medium's state from one to another is known as a phase transition in the domains of chemistry, thermodynamics, as well as other related sciences. The phase is frequently used to describe transitions between the fundamental states of matter.
The physical characteristics of a phase of such a thermodynamic system as well as the states of matter are constant. Some properties of a particular medium change throughout a phase transition as a result of a change in the environment, including such temperature or pressure. Condensation is the phase change in the atmosphere forms clouds.
Therefore, condensation is the phase change in the atmosphere forms clouds.

It was one of the earliest times the concept of crustal motion had been presented to the scientific world, and it lay the foundation for the creation of current plate tectonics, even if Wegener's "continental drift" hypothesis was eventually refuted.
What is Plate tectonics theory?
In order to comprehend mountain-building processes, volcanic eruptions, earthquakes, the evolution of the Earth's surface, and rebuild the continents and oceans that once covered it, plate tectonics, a theory about the dynamics of the lithosphere, revolutionized Earth sciences.
In the 1960s, the theory of tectonics was developed. The lithosphere, which really is typically 100 km thick and sits on top of the asthenosphere, a plastic layer, is said to be Earth's outermost, unyielding layer.
The lithosphere is divided into several small plates, six to eight medium-sized local plates, and seven extremely massive continental and oceanic plates.

b. one-half the original density.
c. two times the original density.
d. one-fourth the original density.
Answers
Answer:
a. the same as the original density.
Explanation:
The density of a material depends only on the properties of the material, so if a block of steel is cut in a half, it is still made of the same material (steel), so it still has the same density.
We can verify it by doing some calculations. In fact, the initial density of the block of steel is given by the ratio between its mass (75 g) and its volume (10 cm^3):
When the block is cut in a half, its mass becomes half:
and its volume also becomes half:
So the new density is
So, the density has not changed.
