1. which of the following is an example of a material whose atoms strongly hold on to electrons?

a. conductor
b. neutral
c. insulator
d. charging material

2. what does the direction of the magnetic field depend on?

a. the direction of the magnetic field will depend on the poles of the wire
b. the direction of the magnetic field will depend on the direction of the current flow
c. the direction of the magnetic field will depend on the direction of the magnetic domains
d. the direction of the magnetic field will depend on the magnetic

1) C.Insulator

2) B.The direction of the magnetic field will depend on the direction of the current flow

Explanation:

1) C.Insulator

The conductors can conduct current because they have free electrons which can move inside the conductor. The free electrons are the outer most electrons of the atoms of conductors they are not bound to any particular atoms hence the name free electron. But there are no free electrons in the insulator because elections, even the outer most electrons, are tightly bound to their corresponding atoms. This is also the reason why insulators cannot conduct electricity.

2) B.The direction of the magnetic field will depend on the direction of the current flow

The direction of magnetic field around the wire can be estimated by using Ampere's right hand grip rule. According to this, if you extend your right hand thumb in the direction of current and curl your remaining fingers around the wire, the direction pointed by the curled fingers is the direction of the magnetic field

when cloud cover increases then the suns ray's which provides the earth with light and warmth gets covered due to the due to the suns ray's being blocked, the temperature in that region

therefore to conclude i would like to say that,

=more the cloud cover, the lesser the

happy to

pls mark as brainliest.
