Answer:
18.7842493212 W
Explanation:
T = Tension = 1871 N
= Linear density = 3.9 g/m
y = Amplitude = 3.1 mm
= Angular frequency = 1203 rad/s
Average rate of energy transfer is given by
The average rate at which energy is transported by the wave to the opposite end of the cord is 18.7842493212 W
Answer:
2.16×10⁻⁶ N
Explanation:
Applying,
F = kqq'/r² (coulomb's Law)....................... Equation 1
Where F = electrostatic force, k = coulomb's constant, q = charge on the styrofoam, q' = charge on the grain of salt, r = distance between the charges.
From the question,
Given: q = 0.002 mC = 2.0×10⁻⁶ C, q' = 0.03 nC = 3.0×10⁻¹¹ C, r = 0.5 m
Constant: k = 8.99×10⁹ Nm²/C²
Substitute these values into equation 1
F = (2.0×10⁻⁶)(3.0×10⁻¹¹)(8.99×10⁹)/0.5²
F = 2.16×10⁻⁶ N
Answer:
10°C
Explanation:
To convert °F to °C, we use the formula:
°C = (°F - 32) * ( 5/9)
So, to convert 50°F to the equivalent in °C, we can proceed as follows:
°C = ( 50 - 32 ) * (5/9)
°C = ( 18 ) * (5/9), which is, approximately,
°C = 9.999999999... ≈ 10 (5/9 ≈0.555555...)
So, 50°F is equivalent to 10°C.
The correct answer is granite oceanic. Continental crust is primarily a granite oceanic. Continental crust is the layers of sedimentary, igneous, and metamorphic rocks that form the area of the shallow seabed that is near the shore.
