Answer:
I = 4 A
Explanation:
When the batteries are connected in parallel, the voltage is the same as the voltage of each battery, but the internal resistance is less, in general we can assume that the internal resistance is also in parallel.
1 / = 1 / r₁ + 1 / r₂ = 2 / r = 2/1
r_{eq} = 0.5 ohm
The current in the resistor is
V = I R + I r_{eq}
I = V / R + r_{eq}
I = 18 / (4 +0.5)
I = 4 A
The area on an entrance ramp where you increase speed to that of expressway traffic is the <u>acceleration lane.</u>
<u></u>
So the correct option is (D) that is acceleration lane.
A section or lane of adjustment for speed that has extra flooring on the borders of the lanes of traffic to let vehicles to accelerate until they merge with the flow of traffic.
Drivers must reach the posted speed limit before entering the acceleration lane, signal, locate a gap in traffic, and then merge.
Drivers can accelerate or decelerate in an area not being used by high-speed through traffic by using acceleration/deceleration lanes, also known as speed-change lanes or auxiliary lanes. The abrupt change in pace can result in stop-and-go traffic, crashes, and other problems on freeways and some major streets. These issues can be reduced by including acceleration/deceleration lanes in the roadway design.

Answer:
The magnitude of the centripetal force that acts on him
Explanation:
Given that,
Mass = 80.0 kg
Distance = 6.10 m
Speed = 6.80 m/s
We need to calculate the magnitude of the centripetal force that acts on him
Using formula of the centripetal force
Where, F = force
m = mass
v = speed
r = distance
Put the value into the formula
Hence, The magnitude of the centripetal force that acts on him
The balanced chemical equation is 2 AlI₃ + 3 HgCl₂ 2 AlCl₃ + 3 HgI₂ for the given chemical reaction.
<h3>What is chemical equation?</h3>
Chemical equation is a symbolic representation of a chemical reaction which is written in the form of symbols and chemical formulas.The reactants are present on the left hand side while the products are present on the right hand side.
A plus sign is present between reactants and products if they are more than one in any case and an arrow is present pointing towards the product side which indicates the direction of the reaction .There are coefficients present next to the chemical symbols and formulas .
The first chemical equation was put forth by Jean Beguin in 1615.By making use of chemical equations the direction of reaction ,state of reactants and products can be stated. In the chemical equations even the temperature to be maintained and catalyst can be mentioned.
