Answer:
the previous correct answer is b
Explanation:
When the circuit is closed in the system, a current is induced that follows the lenz law, which opposes the change that is occurring and therefore the coil increases and the idicidal current in the ring must reach the maximum oppositing is the current of the coil, so quiet force is repulsion
Consequently, the previous correct answer is b
Answer:
Negative
Explanation:
The respiratory plays a remarkable role in the regulation of CO2. It is responsible for gas exchange. The body gets rid of CO2 by breathing out. The goal of respiration is to decrease the CO2 levels.
Kinetic energy=0.5*mass*(velocity^2)
15,000 J=0.5*50*v^2
15,000J=25v^2
600 J=v^2
Velocity= 24.49 ms^-1
Answer:
PLEASE MARK ME AS BRAINLIST
Explanation:
DENSITY = MASS ÷ VOLUME
=31.8÷12.0
=2.65 ml
Answer: frequency = 6.5 Hz
Explanation:
Given that the
Speed V = 65 m/s
Wavelength (λ) = 10m
Wave speed is the product of frequency and wavelength. That is,
V = fλ
Substitute V and (λ) into the formula to get frequency f
65 = 10f
Make f the subject of formula
f = 65/10
f = 6.5 Hz
Therefore, the frequency of this wave is 6.5 Hz?
