Answer:
Yellow, green, polka dot and white jerseys
Explanation:
Tour de France is the biggest bicycle race in the world held at France over a period of 23 days. At the end of each day of racing they give to the certain riders FOUR different colored jerseys:
- The yellow jersey is given to the overall winner at each stage, this shows the rider who was the best in the previous stage.
- The green jersey is given to the best sprinter of each stage,
- The polka dot jersey is given to the rider who first reach the crest of designated hills and mountains at each stage.
- The white jersey is given to the fastest rider at each stage under 25 years at the beginning of the racing year.
At the end of the competition, the total points are counted and the different jerseys are given to the overall winners.
Answer:
The correct option is;
B. Subtract vectors A from C; 
= 12 N
Explanation:
The given parameters are;
The weight of the dresser = 250 N
The force applied by the man = 20 N = C
The frictional force provided by the carpet = 8 N = The component of the weight resisting motion = A
Therefore, the net force tending to put the dresser in motion, , is given as follows;
= The force applied by the man, C - The frictional force provided by the carpet which is the component of the weight resisting motion, A
= C - A = 20 N - 8 N = 12 N
= 12 N
The resulting net force, = 12 N.
Complete question is;
Selena drew a diagram to show how current moves in a loop of wire that is placed between two magnets. At top left a piece of magnet labeled N and at top right a piece labeled S. Between these a square coil of wire with green arrows at its ends away from the magnets pointing away from the magnets. Red arrows point from N to S. Which best explains how Selena can correct her error?
A) She can change the magnets so like poles are facing each other.
B) She can change the arrows so they show current traveling in opposite directions on the sides of the loop.
C) She can change the arrows so they show the magnetic field reversing direction between the magnets.
D) She can change the magnetic poles so they are both on one side of the loop.
Answer:
B) She can change the arrows so they show current traveling in opposite directions on the sides of the loop.
Explanation:
Since the direction of the arrows point north and south whereas the magnets are east and west, it means the arrows are not pointing in the correct direction. To correct it she will have to make sure the arrows are pointing in opposite directions of the magnet via the sides of the loop.
C. in a covalent bond, they are shared by two atoms, while in an ionic bond, they are transferred
