Answer:
The waves are refracted as they travel through the Earth due to a change in density of the medium. This causes the waves to travel in curved paths. When the waves cross the boundary between two different layers, there is a sudden change in direction due to refraction
Answer:6amperes
Explanation:
1/R=1/40 + 1/40
1/R=2/40
Cross multiplying we get
2R=40
Divide both sides by 2
2R/2 =40/2
R=20ohms
Current=voltage ➗ resistance
Current=120 ➗ 20
Current =6amperes
The purpose of nucleophilic substitution reactions of alkyl halides experiment is to demonstrate in the laboratory setting Nucleophilic substitution reactions of alkyl halides.
In this it is been aimed to observe nucleophilic substitution reactions, SN1 and SN2 will by the addition of a solvent to mixtures of alkyl halides. In order to make this experiment effective a standard procedure is being used and noted observations while each reaction occurred.
Nucleophilic substitution reactions are an important class of reactions that allow the interconversion of functional groups. For alcohols, the range of substitution reactions possible can be increased by utilizing the tosylates (R-OTs), an alternative method of converting the -OH to a better leaving group.

Yes, it possible to orient a current loop in a uniform magnetic field such that the loop will not tend to rotate.
The forces on opposing sides of the loop would be equal in magnitude and opposite in direction if the magnetic field is pointed perpendicular to the plane of the loop; yet, there will be no net torque produced on the loop. In a constant magnetic field, there is no torque experienced by a current loop. A current carrying loop in a homogeneous magnetic field will never exert any net magnetic force. In a constant magnetic field, there is no torque experienced by a current loop. Due to the zero torque on the loop in this position, the plane of the loop is parallel to the direction of the magnetic field.
