Answer:
A
Explanation:
The slope of the graph has the units of vertical axis divided by horizontal axis. This means that the slope of a distance vs time graph is distance/time, or velocity.
Slope is calculated by "rise over run" so C is incorrect.
Since the slope represents velocity, a constant slope equates to a constant velocity, hence B is incorrect. Same reasoning for D being incorrect: if the slope is zero, the object is not moving.
Answer:
The initial current in the circuit is 0.1873 mA
Explanation:
Given;
capacitance is given as 3.67 x 10⁻⁶ F
resistance is given as 8010 Ω
voltage across the circuit is 1.5 V
Since the capacitor is initially uncharged, the capacitive reactance is zero.
From ohms law;
Voltage across the circuit is directly proportional to the opposition to the flow of current.
V = IR
I = V/R
I = 1.5/8010
I = 0.0001873 A = 0.1873 mA
Therefore, the initial current in the circuit is 0.1873 mA
Answer:
11.85m
Explanation:
For the development of this problem we must resort to the concepts of the basic kinematic equations that define the distance of a body, such as speed for a certain time, that is,
From the information provided we say that the distance between the cretas is 0.6m,
In our information we have also that the length between the first and latest wave is in time terms of 2.2s. They are 4 waves in 3 intervals then
Then the distance from the shore is given by the speed of the waves for the total time. That is
Answer:
D. Nuclear fusion
Explanation:
Nuclear fusion is a nuclear reaction where nuclei of atoms( one of low atomic number and another with a higher atomic number) join together to form a much bigger nucleus and release a lot of energy.In the sun, which is a star of course, where light is released,hydrogen is converted to helium and the process releases massive energy into space in form of heat and light.
energy moves through the sun in two main way, Radiation and Convection.
Explanation:
as the energy moves outward from the sun's core, 1st enters rhe radiation zone. the radiation zone is a region of highly compressed gas. here the energy is transferred by the absorption and irradiation of electromagnetic waves
