A. Translucent because it’s shows a little light on the inside and looks dark on the outside
Answer:
Ek= 35.392 kJ or 35.392 10³ J
Explanation:
Formula for Kinetic energy:
Ek= × m ×
since m= 65kg and v= 33m/s
Ek= × 65×
Ek= 35.392 kJ or 35.392 10³ J
Answer:
d) a = 4.1 m/s²
Explanation:
m = 92 Kg
∅ = 40º
μ = 0.293
a = ?
We can obtain the forces in the direction x' (of motion)
Wx' = W*Sin ∅ = m*g*Sin ∅
Ffriction = μ*N = μ*m*g*Cos ∅
then we use Newton's 2nd Law as follows:
Wx' - Ffriction = m*a
m*g*Sin ∅ - μ*m*g*Cos ∅ = m*a
⇒ a = g*(Sin ∅ - μ*Cos ∅)
⇒ a = (9.81 m/s²)*(Sin 40º - 0.293*Cos 40º)
⇒ a = 4.1038 m/s²
Answer:
1. The change from a liquid state to a gaseous state: boiling (evaporation)
2. The change from a gaseous state to a liquid state: condensation
3. The change from a solid state to a liquid state: melting
4. The change from a liquid state to a solid: freezing
5. The change from a solid state to a gaseous state: sublimation
6. The change from a gaseous state to so solid: deposition
7. A change of state: phase change
Explanation:
<em>A change of state is a physical change a substance suffers, it changes it physically but not chemically. In the image I added you can observe how these changes occur between the solid, liquid and gaseous states.</em>
