V = f x wavelength
V = 5 x 10
V = 50m/s
Answer:
0.325 N
Explanation:
From the question,
T = 4π²rm/t²............................ Equation 1
Where T = Tension, r = radius or length of the string, m = mass of the string, t = time.
Given: r = 2.4 m, m = 15 g = 0.015 kg, t = 2.09 s.
Constant: π = 3.14
Substitute these values into equation 1
T = 4(3.14²)(2.4)(0.015)/2.09²
T = 1.4198/4.3681
T = 0.325 N
THIS IS NOT THE EXACT ANSWER BUT IT MIGHT HELP
The cover slips serves two purposes: (1) it protects the microscope's objective lens from contacting the specimen, and (2) it creates an even thickness (in wet mounts) for viewing.
Answer:
B: Decreased attention span is the answer.
Explanation:
Just took the test on e d g e n u i t y.
The latent heat of vaporization for water is
2257 KJ per Kg . I'm pretty sure that's exactly
the same as 2257 joules per gram. So ...
When 1 gm of STEAM at 100 C condenses to
1 gm of liquid water at 100 C, it releases
2257 joules of heat energy to its environment.
