(6) Given that,
Force in east direction = 67 N
Force in west direction = 82 N
Solution,
According to the given figure,
Two forces are acting in opposite direction. Maximum force is acting in west direction. It means the net force is acting in west direction.
Net force = 82-67
= 15 N (Due west)
The forces are unbalanced. It is because the magnitude of force in west is more than in east.
Net force = 15 N, Direction of motion = West and the forces are unbalanced.
The brightness of the lamp is proportional to the current flowing through the lamp: the larger the current, the brighter the lamp.
The current flowing through the lamp is given by Ohm's law:

where
V is the potential difference across the lamp, which is equal to the emf of the battery, and R is the resistance of the lamp.
The problem says that the battery is replaced with one with lower emf. Looking at the formula, this means that V decreases: if we want to keep the same brightness, we need to keep I constant, therefore we need to decrease R, the resistance of the lamp.
A.gold is the answer. As it's density is 19.32 grams per cubic centimeter which is lot more than the other substances.
Currently, the magnetic south pole lies about ten degrees distant from the geographic north pole, and sits in the Arctic Ocean north of Alaska. The north end on a compass therefore currently points roughly towards Alaska and not exactly towards geographic north.
Answer:
3.08 Nm
Explanation:
N = 200, diameter = 6 cm, radius = 3 cm, I = 7 A, B = 0.90 T, Angle = 30 degree
The angle made with the normal of the coil, theta = 90 - 30 = 60 degree
Torque = N I A B Sin Theta
Torque = 200 x 7 x 3.14 x 0.03 x 0.03 x 0.90 x Sin 60
Torque = 3.08 Nm
