Answer:
Option B seems to be the appropriate choice,
Explanation:
The given question is incomplete. Please find the attachment of the complete question.
- From either the principle or law of the Coulombs, there would have been either pressure (force) through attachment or repulsion amongst charges.
- It is evident from the analysis presented that perhaps the bee becomes positively (+) charged and would have been drawn either by negatively (-) charged roots of the plants or stem.
As a consequence, the vegetation is electric current polarized because as activated bee pursued.
Answer:
The correct option is b) By the time they get to be theories, they cannot be disproven. It's not necessary that the theories are always right. They can be proven wrong.
Explanation:
Given: Mass m = 0.50 Kg; Force = Weight = mg F = (0.50 Kg)(9.8 m/s²)
F = 4.9 N
Displacement x = 3.0 cm convert to meter x = 0.03 m
Required: Spring constant k = "
Formula: F = kx
k = F/x
k = 4.9 N/0.03 m
k = 163.33 N/m
Answer: Force
Explanation: Force is defined as a push or pull acting on an object
Answer:
8.77×10⁻⁵ m
Explanation:
ω = angular velocity = 3.49 rad/s = 33 rpm
r = Radius of the groove = 0.1 m
f = Frequency = 3.98 kHz
Tangential Velocity of record
v = ωr
⇒v = 3.49×0.1
⇒v = 0.349 m/s
The velocity of the wave is 0.349 m/s
v = fλ
∴ Wavelength in the groove is 8.77×10⁻⁵ m
