Answer:
.000828 j
Explanation:
Work = F * d
.0069 N * .12 m = .000828 j
F = ma
We have mass = 0.2kg
and acceleration = 20 m/s^2
So..
F = (0.2)(20)
F = 4 N
Answer:
v = K √(E / ρ)
Explanation:
Modulus of elasticity has units of N/m², or kg/m/s².
Density has units of kg/m³.
Velocity has units of m/s.
If we divide modulus of elasticity by density, we can eliminate kg:
E / ρ = [kg/m/s²] / [kg/m³]
E / ρ = [m²/s²]
Taking the square root gets us units of velocity:
√(E / ρ) = [m/s]
Multiply by the constant K:
v = K √(E / ρ)
Answer:
1) Are always conservative
Explanation:
Elastic forces are always conservative.
Hope it helps you.
please mark as the brainliest answer.
the answer is d because energy cannot be created nor destroyed, only changed
