<span>A. How could energy become the matter present today? </span>
Answer:
0.5
Explanation:
D = M / V
You divide 300g by 600ml and you get 0.5

Answer:
A) 17.7 m/s
B) 15.98 m
C) Zero
E) 9.8 m/s²
Explanation:
given information
distance, h = - 34 m
time, t = 5 s
A) What is the initial speed of the egg?
h - h₀ = v₀t - 
t², h₀ = 0
- 34 = v₀ 5 - \frac{1}{2} 9.8 5²
- 34 = 5 v₀ - 122.5
v₀ = 122.5 - 34/5
= 17.7 m/s
B) How high does it rise above its starting point?
v² = v₀² - 2gh
v = 0 (highest point)
2gh = v₀²
h = v₀²/2g
= 17.7²/2 (9.8)
= 15.98 m
C) What is the magnitude of its velocity at the highest point?
v = 0 (at highest point)
E) What are the magnitude and direction of its acceleration at the highest point?
g= 9.8 m/s², since the egg is moved vertically, the acceleration is the same as the gravitational acceleration.
In order to create a magnifier in convex lens, you should choose a short focal length that is lesser than 1 meter.
<h3>What is a
convex lens?</h3>
A convex lens is also referred to as converging lens and it can be defined as a type of lens that typically causes parallel rays of light with respect to its principal axis to come to a focus (converge) and form a real image.
In Science, a magnifier refer to an optical instrument that allow us to look at a very near object because its image is generally formed farther away. Thus, the image of the object appears to be much larger.
In this context, you should choose a short focal length that is lesser than 1 meter when you want to create a magnifier in convex lens because the nearer the object is to the lens, the larger would be the image formed.

Answer:
P = 0.6814 MPa
Explanation:
For this exercise we must use the Betuliano relation
P₁ + ½ ρ v₁² + ρ g y₁ = P₂ + ½ rho v₂² + rho g y₂
where we use the subscript 1 for the first pipe and the subscript 2 for the second pipe
indicate that the two pipes are at the same level therefore
y₁ = y₂
P₂ = P₁ + ½ ro (v₁² - v₂²)
let's calculate
P₂ = 13,785 10⁵ + ½ 997 (41,221² - 55,654²)
P₂ = (13.785 - 6.97) 105
P₂ = 6.814 10⁵ Pa
let's reduce to Mpa
P₂ = 6.814 10⁵ Pa (1 MPa / 10⁶ Pa)
P₂ = 6.814 10-1 MPa
P = 0.6814 MPa
