It would cost $0.69 to operate the monitor for a day.
Recall this kinematic equation:
a =
This equation gives the acceleration of the object assuming it IS constant (the velocity changes at a uniform rate).
a is the acceleration.
Vi is the initial velocity.
Vf is the final velocity.
Δt is the amount of elapsed time.
Given values:
Vi = 0 m/s (the car starts at rest).
Vf = 25 m/s.
Δt = 10 s
Substitute the terms in the equation with the given values and solve for a:
a =
<h3>a = 2.5 m/s²</h3>
Answer:
I need to be still. 450 miles an hour. That was stupid of him lol.
Explanation:
Answer:
v = 4 m / s
Explanation:
In this exercise we are asked to find the speed of the wave, which is described by the expression
v = λ f
in this case the wave has 4 nodes and 3 antinodes, in a length of 12 m
for a standing wave it is satisfied that we have a full wavelength and a half of another
L = λ + ½ λ
L = λ
λ = ⅔ L
Cambien indicates that it has a frequency of
f = 0.5 Hz
we substitute
v = ⅔ L f
let's calculate
v = 12 0.5
v = 4 m / s
Answer:
If the collector of the cell is covered, the voltage is higher
Explanation:
The collector of the a passive, active, or photovoltaic (PV) solar cell is the device that takes the Sun's energy by the absorption of the Sun's radiation which is then transformed into electricity and heat. The ability to absorb the Sun's energy is given by the material type and the coating of solar collector
Therefore, the device requires access to energy from Sunlight to get the energy which can be stored in a rechargeable cell and well the collector's cell is covered, access to Sunlight is denied and therefore energy is not supplied to the cells and current is not generated and there is no flow of electricity and the voltage in the circuit is lower or there is no voltage in the circuit
The statement which is wrong about the solar cell is therefore, that <em>if the collector of the cell is covered, the voltage is higher</em>
