Answer:
It's B energy is absorbed by the reaction,hope this helps !:).
Explanation:
Answer:
B) the potential drop is always the same across each resistor
Explanation:
Resistors are said to be in parallel if they are connected in different branches, and the end of each branch corresponds to the end of the other branches: so that, they are connected to points at same voltage. So, resistors in parallel have the same potential drop across them.
Therefore, we can analyze each statement:
A) the largest resistance has the largest current through it. --> FALSE. The current through each resistor is given by Ohm's law:
where V is the potential drop and R the resistance. As we see, since the voltage is constant, the larger the resistance, the less the current.
B) the potential drop is always the same across each resistor. --> TRUE, for what we said above.
C) the same current always runs through each resistor. --> FALSE, for what we said in part A.
D) the power generated in each resistor is the same. --> FALSE. The power dissipated in each resistor is
where V is the voltage and R the resistance; the voltage is the same for all resistors, however the resistance is not, so the power dissipated is not the same.
Answer:
Explanation:
The resultant velocity of the motorboat due to the current perpendicular to the motion of the boat can be calculated by drawing a triangle to represent this motion. The velocity of the motorboat is the base whereas the velocity of the river is the perpendicular of the triangle (picture attached).
The angle is (perpendicular/base);
(5/20)= 14.0;
The triangle can be enlarged such that the perpendicular now represents the width of the river and the perpendicular represents the distance between the dock and landing place.
The distance between dock and landing place is:
a) base*Tan(∅) = 2*Tan(14) = 0.5km
b Time = 2/20= 0.1 hours. This is because the horizontal component of the motion due to velocity of motor boat will be considered for horizontal distance of 2 km.
