Two long parallel wires separated by 4.0 mm each carry a current of 24 A. These two currents are in the same direction. What is
lesya [120]

Answer:

Explanation:

Magnetic field at a a point R distance away

B = μ₀ / 4π X 2I / R where I is current

Magnetic field due to one current

=  10⁻⁷ x 2 x 24 / 1 x 10⁻³

48 x 10⁻⁴ T

Magnetic field due to other current

=  10⁻⁷ x 2 x 24 / 3x 10⁻³

16 x 10⁻⁴ T

Total magnetic field , as they act in opposite direction, is

= (48 - 16 ) x 10⁻⁴

32 x 10⁻⁴ T .

Students create a standing wave
kenny6666 [7]

wavelength =wavevelocity

--——————

Frequency

Frequency = 1/T => 1 / 6.73 = 0.1486

Wave velocity = L/T => 3.75 / 6.73 = 0.5572

Therefore, wave length = 0.5572/0.1486 = 3.75m

An unknown mass of each of the following substances, initially at 23.0, absorbs 1910 of heat. The final temperature is recorded
babymother [125]
The data not given here is the specific heat capacity of pyrex glass equal to 0.75(J/g  °C). In this case, heat is equal to mass x specific heat capacity x temperature rise. Temperature difference is then equal to 1910 J / 0.75 J/g  °C / 23 g equal to 110. 75  <span>°C </span>
