Kinetic energy = 1/2 mv²
so, you will have to do it for every single one of them if you want steps.
Kinetic Energy = For A, 202500J
For B, 90000J
For C, 168750J
For D, 75000J
From the above we an say that kinetic energy is highest in option A.
In case, there are no steps needed, just by the values we are able to understand the answer as in Option A, eventhough the mass is the same, higher the velocity or speed, higher the kinetic energy
An influence upon an oscillatory system that has the effect of reducing/restriction or preventing its oscillations. Damping is produced by processes that dissipate the energy stored in the oscillation.
Answer:
1. Count the atoms of each element in the reactants and the products.
2. Use coefficients; place them in front of the compounds as needed.
Explanation:
Answer:
A. 59.4
Explanation:
The refractive index of the glass, n₁ = 1.50
The angle of incidence of the light, θ₁ = 35°
The refractive index of air, n₂ = 1.0
Snell's law states that n₁·sin(θ₁) = n₂·sin(θ₂)
Where;
θ₂ = The angle of refraction of the light, which is the angle the light will have when it passes from the glass into the air
Therefore;
θ₂ = arcsin(n₁·sin(θ₁)/n₂)
Plugging in the values of n₁, n₂ and θ₁ gives;
θ₂ = arcsin(1.50 × sin(35°)/1.0) ≈ 59.357551° ≈ 59.4°
The angle the light will have when it passes from the glass into the air, θ₂ ≈ 59.4°.
The answer is option A.
Centripetal force is always directed towards the centre and does not change the speed of the body,but there is a change in the direction.
