Answer:
A. the wave speed v and Wavelength
Explanation:
Given that
Mass density per unit length=μ
Frequency = f
The velocity V given as
T=Tension
V=Velocity
V= f λ
λ=Wavelength
Therefore to find the tension ,only wavelength and speed is required.
The answer is A.
Lets make the original number of nuclides at the start is 100.
If 7/8 of 100 is decayed, that means 87.5 decayed.
And there is 1/8 left of the number of nuclide 100. Which is 12.5
How many Half lifes passed for 100 to become 12.5 is 3 Half-Lives.
Each Half-Life is 80 seconds so there is 240 seconds
The answer is that it takes 240 seconds.
Answer:
Explanation:
As we know that heat released is given as
here we know that
Q = 2000 J
m = 0.6 kg
s = 4186 J/kg C
now from above equation we have
Answer:
8.02×10⁵ m
Explanation:
Equation for centripetal force:
F = mv²/r
Solving for r:
r = mv²/F
Given:
F = 8955 N
m = 1160 kg
v = 7446 m/s
r = (1160 kg) (7446 m/s)² / 8955 N
r = 7.182×10⁶ m
The height above the surface is:
h = 7.182×10⁶ m − 6.38×10⁶ m
h = 0.802×10⁶ m
h = 8.02×10⁵ m
The two principal parts of an AC induction motor are the stator and the rotator.
Hope this helped! (:
