Answer:
25.13 cm
Explanation:
Mrs. Lynn's art class is making pencil holders out of soup cans
These soup cans are definitely in cylindrical forms.
Each student is first covering a can with felt.
A felt is a type of material that is used for covering other objects. Here a felt is used to cover soup cans.
So if the diameter of the bottom of the can is 8 cm (i.e d = 8cm)
What will the circumference of the piece of felt need to be in order to cover the bottom of the can?
The felt will also take the circumference of a cylinder; and which is given by the expression
C = 2 πr
since diameter (d) = 8 cm
radius (r) = 
r = 
r = 4 cm
C = 2 × π × 4 cm
C = 2 × 3.142 × 4 cm
C = 25.13 cm
∴ the circumference of the piece of felt need to be 25.13 cm in order to cover the bottom of the can.
Answer:
1.2826 x 10^-13 m
Explanation:
Here, k be the kinetic energy and m be the mass
K = 50 KeV = 50 x 1.6 x 10^-16 J = 80 x 10^-16 J
m = 1.67 x 10^-27 kg
λ = 1.2826 x 10^-13 m
Answer:
agricultural production of food
Explanation:
Answer:
C) True. S increases with time, v₁ = gt and v₂ = g (t-t₀) we see that for the same t v₁> v₂
Explanation:
You have several statements and we must select which ones are correct. The best way to do this is to raise the problem.
Let's use the vertical launch equation. The positive sign because they indicate that the felt downward is taken as an opponent.
Stone 1
y₁ = v₀₁ t + ½ g t²
y₁ = 0 + ½ g t²
Rock2
It comes out a little later, let's say a second later, we can use the same stopwatch
t ’= (t-t₀)
y₂ = v₀₂ t ’+ ½ g t’²
y₂ = 0 + ½ g (t-t₀)²
y₂ = + ½ g (t-t₀)²
Let's calculate the distance between the two rocks, it should be clear that this equation is valid only for t> = to
S = y₁ -y₂
S = ½ g t²– ½ g (t-t₀)²
S = ½ g [t² - (t²- 2 t to + to²)]
S = ½ g (2 t t₀ - t₀²)
S = ½ g t₀ (2 t -t₀)
This is the separation of the two bodies as time passes, the amount outside the Parentheses is constant.
For t <to. The rock y has not left and the distance increases
For t> = to. the ratio (2t/to-1)> 1 therefore the distance increases as time
passes
Now we can analyze the different statements
A) false. The difference in height increases over time
B) False S increases
C) Certain s increases with time, v₁ = gt and V₂ = g (t-t₀) we see that for the same t v₁> v₂
