This is true
In the winter they just fall off
The object with the greater mass should be attached to the spring with the smaller spring constant, so that the resulting spring-object system has the greatest possible period of oscillation.
Answer: Option D
<u>Explanation:
</u>
According to the simple harmonic motions, from physics, it gives a relation between deformation force and the deflection. The more deflection results in more time period of oscillation.
F = - k x
where ‘k’ is the spring constant, and ‘F’ is the deformation force.
So, deflection is directly proportionate to forces, and inversely proportionate to its spring constant. Hence, we can derive that the force must be maximum, and hence weight must be maximum, with the spring constant lesser. Then, the deflection will be high. So, time period increases.
Answer:
P₂ = 2541.24 kPa
Explanation:
The pressure can be find using the law of gases and fluids of the thermodynamic so:
Δ P = ¹/₂ * γ / g * ( V₂² - V₁² )
V² = u² + v²
Solving using the equation
φ = 2 x² * y - ²/₃ * y ³
At the point (1.1)
u = 4 * x *y ⇒ u₁ = 4 * 1 * 1 = 4 m/s
v₁ = 2x² - 2y² ⇒ v₁ = 2 * 1² - 2 * 1² = 0
V₁² = 4² + 0² = 16 m² / s²
At the point (1,7 . 1,7)
u = 4 * x *y ⇒ u₁ = 4 * 1.7 * 1.7 = 11.56 m/s
v₂ = 2x² - 2y² ⇒ v₂ = 2 * 1.7² - 2 * 1.7² = 0
V₂² = 11.56² + 0² = 133.6336 m² / s²
Replacing
Δ P = ¹/₂ * γ / g * ( V₂² - V₁² ) ⇒ P₁ - P₂ = ¹/₂ * γ / g * ( V₂² - V₁² )
P₂ = P₁ + 0.5 * γ / g * ( V₂² - V₁² ) ⇒ P₂ = 2600 kPa + 0.5 * 9.8 x 10³ / 9.8 m/s₂ * ( 16 - 133.6336 )
P₂ = 2541.24 x 10³ Pa
P₂ = 2541.24 kPa
It is called <em>refraction</em> and is caused the the clear surface bending the light to make it appear different colors or look like it is bent.
