To solve this, we use the Wien's Displacement Law as shown in the attached picture. First, convert the temperature to Kelvin.
C to F:
C = (F - 32)*5/9
C = (325 - 32)*5/9 = 162.78 °C
C to K:
K = C + 273
K = 162.78 + 273 = 435.78 K
λmax = 2898/435.78 =
<em>6</em><em>.65 μm</em>
The number of protons determines the element. Many elements also have many isotopes. Such as carbon-14 Carbon-12 and carbon-10.
Answer:
u have to purchase it via online e-commerce platforms
Answer:
The correct answer is option a.
Explanation:
Conservation of momentum :
Where :
= masses of object collided
= initial velocity before collision
= final velocity after collision
We have :
Two equal-mass carts roll towards each other.
Initial velocity of 
Initial velocity of 
(opposite direction)
Final velocity of 
(same direction )
Final velocity of 
(same direction)
v = 0.5 m/s
rg135
The speed of the carts after their collision is 0.5 m/s.
Venus is the hottest world in the solar system. Although Venus is not the planet closest to the sun, its dense atmosphere traps heat in a runaway version of the greenhouse effect that warms Earth.
