Alright let's start this off with our basic equation!
Accerlation (
a) = ?
Initial velocity (
V1)= 60 mph = 88 ft/s (because we HAVE to convert mph to ft/s to match time)
Final velocity (
V2) = 0 ft/s because the car stops
Time (
t) = 4 seconds
a =
a =
a =
a = -22
Therefore, your acceleration is -22 ft/s² !! Hope this helped and was one of the branliest answers :')
Answer:
intensity is 8.9 x W/m²
power is 11.3 x W
Explanation:
Given data
distance = 20 light year
power output = 4.00 x 10^28
to find out
intensity of the starlight and the power of the starlight
solution
we know the intensity formula that is
intensity = power / area
so here power is 4.00 x 10^28 and area = 4π(20ly)²
intensity = 4.00 x 10^28 / (4π (20×9.46×10^15)²
intensity = 8.9 x
so intensity is 8.9 x W/m²
and
power is Intensity × Area
so power = 8.9 x × (π (6.37 × 10^6)²
power = 11.3 x
so power is 11.3 x W
Uhh it might be D.why are the lightbulbs burning out
Electric Heating systems use electricity as a source of heat.
<u>Explanation:
</u>
Each heater consists of an electric resistor, which the heating element in it. The process involved is Joule Heating. It is the phenomenon in which, passage of electric current produces heat. Heat is generated when the electrons from the current and the positive ions of the conductor start interaction.
The presence of voltage difference makes an electric fields, which in turn accelerates the charges present in the conductors. When they collide with ions of conductor, heat gets generated, and emitted out, which we use for heating purposes.
Answer:
To use them in future projects and saving the community.
Explanation:
An explanation about using them in future projects is that you can, for example, use plastic for a biology project. It's also a proven fact that recycling can help the environment so there will be less pollution due to having certain recyclables in the wrong places such as the ocean.
