A very long thin wire carries a uniformly distributed charge, which creates an electric field. The electric field is (2300 N/C , toward the wire) 4.10 cm from the wire Consider a 1.00-cm-long segment of the wire. How much charge (in nC) is on this segment ?

Apositive charge moves in the direction of an electric field. which of the following statements are true? check all that apply. check all that apply. 1.the potential energy associated with the charge decreases. 2. the electric field does positive work on the charge. 3. the electric field does negative work on the charge. 4. the potential energy associated with the charge increases. 5. the electric field does not do any work on the charge. 6. the amount of work done on the charge cannot be determined without additional information.

Explain why you think this diagram shows what happened to the carbon in the biodome.

Patients with brain tumors may elect to have a procedure known as gamma knife. in a typical gamma knife procedure gamma rays are directed toward a tumor with contact to surrounding tissues. limiting contact between gamma rays and healthy tissue is important because
