Answer:
Planets were like gods.
Explanation:
To the people of many ancient civilizations, the planets were thought to be deities. Our names for the planets are the Roman names for these deities. For example, Mars was the god of war and Venus the goddess of love.
I = pressure amplitude given = 0.2 W/m²
dB = decibel reading
decibel reading from the pressure amplitude is given as
dB = 10 log₁₀ (I/10⁻¹²)
inserting the values in the above equation
dB = 10 log₁₀ (0.2/10⁻¹²)
dB = 10 log₁₀ (2 x 10⁻¹/10⁻¹²)
dB = 10 log₁₀ (2 x 10⁻¹.10¹²)
dB = 10 log₁₀ (2 x 10¹²⁻¹)
dB = 10 log₁₀ (2 x 10¹¹)
dB = 113.01 db
hence the decibel reading comes out to be 113.01 db
the answer is C.
if the cost of it is too high, then the producer makes no product, resulting in an unsuccessful business
Answer:0.642
Explanation:
Given
initially car is at rest i.e u=0
When car hits the truck it's velocity is 4.5 m/s
it hits the truck after 7 sec
Now average acceleration of car is =
average acceleration of car =
average acceleration of car=
average acceleration of car=
Taking Down hill as positive x axis
average acceleration of car=
Static electricity works when there is an imbalance of positive and negative charges, and thus causes a little spark.
