Angular acceleration and angular velocity are related through the formula a = Δω/Δt, where a is angular acceleration, Δω is the change in angular velocity, and Δt is the change in time. This means that angular acceleration is the rate of change of angular velocity.Po...
The diurnal amplitude of the heat-flux wave (M s ) decreases exponentially with regolith depth and planet’s spin rate according to the formula (Ochsner et al. 2007): MathML (27) where M(z, ω) is the amplitude at depth z and rotational frequency ω, and M s is the heat-wave...

The question asks for his average acceleration in the interval of 2 minutes to 8 minutes. The formula for average acceleration is ∆V/∆t, but the final velocity is already given, so there is no need to calculate it. The correct answer is 0.00694 m/s^2. ...
The analytic solution of the average electron velocity vector W(t) of an electron swarm in gas under ac electric and dc magnetic fields (E(t) and B, respectively) in a constant-collision-frequency model is extended to cover not only the known case of a right crossing angle (E(t)⊥B)...
In the formula of the drag force, the relative velocity difference 𝑣′(𝑡)=𝑣(𝑡)−𝑣0(𝑡)v′(t)=v(t)−v0(t) has to be used, which is the difference between the WEC’s velocity 𝑣(𝑡)v(t) and the vertical velocity of the surrounding water particles 𝑣0(𝑡...
In the formula of the drag force, the relative velocity difference 𝑣′(𝑡)=𝑣(𝑡)−𝑣0(𝑡)v′(t)=v(t)−v0(t) has to be used, which is the difference between the WEC’s velocity 𝑣(𝑡)v(t) and the vertical velocity of the surrounding water particles 𝑣0(𝑡...
Based on the above analysis, 𝑢𝑜𝑝𝑡1uopt1 is first obtained from the value function shown in (8), and under the action of 𝑢𝑜𝑝𝑡1uopt1, the updated formula of EMA is: 𝑆𝐸𝑀𝐴−𝑞(𝑘)=𝛼𝑆𝑞−𝑜𝑝𝑡1(𝑘)+(1−𝛼)𝑆𝐸𝑀𝐴−𝑞...
In the formula of the drag force, the relative velocity difference v (t) = v(t) − v0(t) has to be used, which is the difference between the WEC's velocity v(t) and the vertical velocity of the surrounding water particles v0(t) (see Equation (45)). v0(t) = − Hπ T...
