Answer:
Explanation:
A differential equation that contain a term with di(t)/dt is in a RL circuit. Here we have
where vr is the voltage in the resistance, vi is the voltage in the inductance and vb is the source voltage. But also we have that
where L is the inductance of the circuit, r is the resistance an i is the current. By replacing we have the differential equation
I hope this is useful for you

Answer:
During a chemical reaction, Bromine (Br) would be expected to <u><em>gain 1 valence electron to have a full octet.</em></u>
Explanation:
In the periodic table the elements are ordered so that those with similar chemical properties are located close to each other.
The elements are arranged in horizontal rows, called periods, which coincide with the last electronic layer of the element. That is, an element with five electronic shells will be in the fifth period.
The columns of the table are called groups. The elements that make up each group coincide in their electronic configuration of valence electrons, that is, they have the same number of electrons in their last.
The elements tend to resemble the closest noble gases in terms of their electronic configuration of the last layer, that is, having eight electrons in the last layer to be stable.
Bromine belongs to group 17 (VII A), which indicates that it has 7 electrons in its last shell. So bromine requires more energy to lose all 7 electrons and generate stability, than it does to gain 1 electron and fill in 8 electrons to be stable. So:
<u><em>During a chemical reaction, Bromine (Br) would be expected to gain 1 valence electron to have a full octet.</em></u>
Answer:
Random motion
Explanation:
If the boy throws the basketball forward while at a position on the skateboard, the motion of the ball will be a random motion since we are not told if the ball is moving on a straight line when thrown forward.
In this case, the boy will tend to move in the direction of the ball. Since the ball is moving in a random manner, the motion of the boy will also be a random motion.
A random motion is a motion of a body in a zig zag manner. It is also known as Brownian motion e.g motion of a buzzing mosquito, motion of a smoke coming out of a chimney etc.
Answer:
The choice of building materials and techniques can help them cool down faster, after heating up is explained below in brief details.
Explanation:
Building materials
Buildings that are composed of rock, bricks, or pavement, or inserted into the territory, can seem cooler thanks to the great "thermal mass" of these elements – that is, their capability to assimilate and discharge heat gently, thereby softening temperatures over time, producing daytime cooler and night-time warmer.
Answer:
Furthermore, the AEC said that the Joint Committee has made its position clear that it would no longer authorize any such subsidies. Yet, Mr. Chairman, we find.
