The force is a noncontact force that is created by the movement of an electrical charge. a. centrifugal b. electromagnetic c. resistance d. gravitational

the answer for your question is B. Electromagnetic. because electric charge is the physical property that causes it to experience force when it is placed in a electromagnetic field the electric charge is carried by subatomic particles which causes the movement of the magnetic force

It’s (B) as Electromagnetic force.

Non-contact forces are those which act on an object without any physical contact with that object. The electromagnetic force is responsible for the interaction between electrically charged particles. So when electric charges move they produce the electromagnetic field in their surroundings. These fields act as the electromagnetic force for the other charged particles or object present within its sphere.

here are some of the ways in which chemical and nuclear reactions differ.

explanation:

answer: semi-infinite solid initially at a uniform temperature of 400 ◦c is cooled at its surface by convection. the cooling fluid at a constant temperature of 200 ◦c has a convective coefficient (ha) of 250 w/m2.k. the physical properties of the solid: k = 20 w/m.k and α = 4 * 10-5  m2/s. using δx = 0.04 m and δt = 10 s. write the finite difference equations describing the transient heat transfer of the first five δx and the temperature profile after 30 s.
