Answer:
i = 5.28 A
Explanation:
The magnetic force is given by the expression
F = i l x B
the bold letters indicate vectors, let's write the modulus of that expression, where the direction between the conductor and the magnetic field is 90º, therefore the sine 90 = 1
F = i l B
i = F / l B
let's reduce the length to the SI system
l = 10 cm (1m / 100 cm) = 0.10 m
let's calculate
i = 12.9 / 0.1 3.6
i = 5.28 A
Snowshoes enable a person to walk on depp snow because the snowshoes increase the area over which the person´s wight is distributed.
b.increase the area over which the person´s wight is distributed.
Answer:
Reorder the steps so that step 4 appears before step 3
Explanation:
In a nuclear power plant, we have;
1) Nuclear reaction between the radio active species and the particles takes place to generate energy in the nucleus of atoms
2) The nuclear energy in the atom is converted into radiant energy, which is the energy found in light, and thermal (heat) energy
3) The produced radiant and thermal energy is released as heat and light
4) With the produced heat, steam is generated
5) The generated steam turns the steam turbines and produced mechanical energy
6) The produced mechanical energy is then converted into electrical energy in the electrical generator of the power plant
To correct Savion's error, Step 4) the light and heat should be released before step 3) the released heat can be used to generate steam, we therefore reorder the steps so that step 4 appears before step 3.
Answer:
The most common type of descriptive research is the case study, which provides an in-depth analysis of a specific person, group, or phenomenon.
