Answer:
Recall, The magnetic field on a electron in a wire, Bₓ = (µ₀ I)/(2πr)
Note: Magnetic force direction is at right angles to electron motion.
Magnetic force, F = q * v * Bₓ
Substituting Bₓ into F, we have
F = q * v * Bₓ = (q * v * µ₀* I)/(2π r) = (1.6 x 10⁻¹⁹ x 1.0 x 10⁷ x 4π x 10⁻⁷ x 50)/( 2π x 5 x 10⁻²) = 3.2 x 10⁻¹⁶ N
a) Hence, the magnitude of the magnetic force on the electron if the electron velocity is directed (a) toward the wire is 3.2 x 10⁻¹⁶ N and opposite the current
b) Hence, the magnitude of the magnetic force on the electron if the electron velocity is directed (b) parallel to the wire in the direction of the current is 3.2 x 10⁻¹⁶ N and away from the wire.
c) Hence, the magnitude of the magnetic forces on the electrons if the electron velocity is perpendicular to the two directions defined by (a) and (b) is 3.2 x 10⁻¹⁶ N and (a) direction - opposite the current, (b) same direction as current.
The answer is c. the degree of wetness of the paper towels.
If a pizza is round like a ball it will roll off a cliff.If it’s just flat and round it won’t.
Answer:
In the table, 1=46.7 °C, 1=165 J, 2=819 J, 3=1510 J, and 4=2830 J.
Other experiments determine that the material has a temperature of fusion of
fusion =235 °C and a temperature of vaporization of vapor=481 °C.
If the sample of material has a mass of =8.60 g, calculate the specific heat when this material is a solid, and when it is liquid, l
Computer simulation is useful because it helps in the prediction of what will likely happen in the future using data from past events.
<h3>What is computer simulation?</h3>
- This is the use of computer models to represents a hypothetical scenarios that are likely to be obtained in the real world.
Computer simulations are useful in studying phenomena in the universe because they help us to achieve the followings;
- It helps in the prediction of what will likely happen in the future using data from past events.
- It saves cost and time of carrying out actual experiments.
- It can help prevent a disaster that may occur in the future.
