A. The truck exerts a greater force on the car than the car exerts on the truck.
The answer is hang glider.
<h3>What is the model?</h3>
In high school, I created a project for a similar experiment that was accepted.
It matters what you carry the egg in because it is an egg, so something cushioned.
Use the fabric and cut the paper bag to make the kind of parachute I mentioned before.
When people go sky divining, they use a specific kind of parachute because the design is supposed to slow the fall and give them a chance to make a safe landing.

Answer:
The speed of the stone when it is 4.66 m higher is 236.057 m/s.
Explanation:
Given the initial velocity and vertical distance, we can use the fourth kinematic equation () to find v final, or the v to the left of the equal sign. We know (initial velocity) is 24.7 m/s, y (change in vertical distance) is 4.66 m, and a is another way to write g (acceleration due to gravity), or 9.8 .
From here you could plug in the values and solve for v final, but to make the solving process simpler, we can simplify the given equation, <em>then </em>plug in the known values.
To isolate v final, we can take the square root of and do the same to the right side of the equation. Therefore, we can find v final with: , where v initial is outside of the square root because it squared...
If we plug in the known values to the simplified equation, we get:
The final answer is 236.057 m/s.
Given Information:
Index of refraction of glass = n₂ = 1.42
Angle of reflection = θ₁
Angle of refraction in terms of angle of reflection = θ₂ = 0.5θ₁
Required Information:
Angle of refraction = θ₂ = ?
Answer:
Angle of refraction = θ₂ = 44.76°
Explanation:
We know from the Snell's law that
n₁sinθ₁ = n₂sinθ₂
Where n₁ is index of refraction of air and n₂ is index of refraction of glass, θ₁ is the angle of reflection and θ₂ is the angle of refraction.
Assuming n₁ = 1
1*sinθ₁ = 1.42*sinθ₂
since θ₂ = 0.5θ₁
1*sinθ₁ = 1.42*sin0.5θ₁
1/1.42 = sin0.5θ₁/sinθ₁
sin⁻¹(1/1.42) = sin⁻¹(sin0.5θ₁/sinθ₁)
44.76° = 0.5θ₁
θ₁ = 44.76°/0.5
θ₁ = 89.52°
So the angle of refraction is
θ₂ = 0.5(89.52°)
θ₂ = 44.76°
1. The property of a conductor by virtue of which it posses the flow of electric current through it is called resistance.
2. The resistance of a conductor depends on the cross sectional area of the conductor and it's resistivity.
3.This id due to the fact that the resistance of a wire is inversely proportional to the square of its diameter.
4.Due to at high temperatures , the alloy donot oxidize. Alloy doesn't melt readily and get deformed.
