The characteristic of life would be homeostasis. Homeostasis regulates the variables in which internal conditions remain stable and consistent. This type of regulation is the regulation of temperature and the balance between acidity and alkalinity, also known as pH. Hope this helps! :)
Answer:
0.23348 A
Explanation:
B = Magnetic field
v = Velocity of electron =
q = Charge of electron =
= Vacuum permeability =
r = Radius of circle = 0.026 m
N = Number of turns = 103 turns/cm =
I = Current
The magnetic and centripetal force will be balanced
The magnetic field in solenoid is given by
From the first equation
The current in the solenoid is 0.23348 A
Answer: (A) 1.5 m
Explanation:
This situation is due to Refraction, a phenomenon in which a wave (the light in this case) bends or changes its direction when passing through a medium with an index of refraction different from the other medium.
In this context, the index of refraction is a number that describes how fast light propagates through a medium or material.
In addition, we have the following equation that states a relationship between the apparent depth and the actual depth :
(1)
Where:
is the air's index of refraction
water's index of refraction.
is the actual depth of water
Now. when is smaller than the apparent depth is smaller than the actual depth. And, when is greater than the apparent depth is greater than the actual depth.
Let's prove it:
(2)
Finally we find the apparent depth of water, which is smaller than the actual depth:
Answer:
L = 0.44 [m]
Explanation:
Here we can use the Lorentz transformation related to length to solve it:
<u>Where</u>:
L₀ is the length of the moving reference frame (penguin #1)
L is the length of the fixed reference frame (penguin #2)
β is the ratio between v and c
<u>We know that v = 0.9c so we can find β.</u>
Therefore, the length of the meter stick of #1 observed by #2 is 0.44 m.
I hope it helps you!
More work was done in the skateboard that came to a stop because the one that rolled across the room moved on a surface with less friction while the second board used more work to move on a surface with much friction.
