The equivalent resistance of several resistors connected in series is
the sum of their individual values.
Four 75-ohm resistors connected in series are electrically equivalent
to a single resistor of 300 ohms.
The battery voltage doesn't matter. In fact, it doesn't matter whether the
resistors are anywhere near a battery or not. They could just as well still
be in the little Radio Shack envelope on the top shelf of the storage room.
If they're connected in series, then they're still electrically equivalent to a
single 300-ohm resistor.
Answer:
Wave Variables
In the chapter on motion in two dimensions, we defined the following variables to describe harmonic motion:
Amplitude—maximum displacement from the equilibrium position of an object oscillating around such equilibrium position
Frequency—number of events per unit of time
Period—time it takes to complete one oscillation
For waves, these variables have the same basic meaning. However, it is helpful to word the definitions in a more specific way that applies directly to waves:
].
Explanation:
0.9 is less than 1.0 by 0.1
so your answer is true

Hello!
On a cold winters day, if you left a drink setting outside, it could freeze because the heat (related to the kinetic energy) of the atoms in the drink will be transferred to the environment to achieve energy equilibrium.
Heat transfer occurs by various mechanisms, flowing from the hottest body to the coldest, that's why the heat goes from the drink, which has a higher temperature (and kinetic energy) to the environment, which has a lower temperature. This is described by the second law of thermodynamics
Answer:
Distance(h1) = 12 m
Explanation:
Given
:
Height of cliff (h) = 4m
Time (t) = 1s
Intial velocity (u) = 0m/s
Computation:
Distance(h) = 1/2(g)(t)²
4 = 1/2(g)
g = 8m/s
²
Distance(h1) = 1/2(g)[(t1)²-(t)²]
Distance(h1) = 1/2(8)(3)
Distance(h1) = 12 m
