The element Nitrogen is
usually present in almost all proteins, and it also forms strong bonds due to
its ability to form a triple bond with its self, also to other elements.
<span>The nitrides use a variety
of different oxidation and almost all the oxides forms gasses are at 25 degrees
Celsius. The oxide of nitrogen are acidic, thus, easily attaching protons.</span>
Answer:
Low-temperature blackbody
Explanation:
There are 3 types of blackbody temperatures.
Low-temperature blackbody
High temperature extended area blackbody
High-temperature cavity blackbody
A Low-temperature blackbody is a type of black body radiation that has the range of -40° C to 175° C, typically between 233 K and 448 K. A perfect fit for the temperature range mentioned in the question, "a few hundred Kelvin". Therefore, it's the kind of blackbody temperature that the object would emit.
The period of a mass-spring system is:
T = 2π
T = period, m = mass, k = spring constant
Given values:
T = 8π s
k = 2 N/m
Plug in and solve for m:
8π = 2π
= 4
m/2 = 16
m = 32 kg
Choice A
To solve this problem we use kinematics formulas.
to. What was the acceleration of the rocket during the first 16-s?
Where
= speed after 16 s
= initial velocity = 0
= acceleration during 16 s
Now we use the formula for the position:
Where:
= position after 16 s
= initial position = 0
= 16 s
Then, we know that the altitude of the rocket after 20 s is 5100 meters.
Then we will raise the equation of the position of the rocket from the instant to
where:
Now we clear .
The aceleration is
So:
What is the speed of the rocket when it passes through a cloud at 5100 m above the ground?
The speed is 392.32 m/s
