\sf Force = mass \times acceleration\\\\12~N = 8~kg \times acceleration\\\\ acceleration =  \frac{12~N}{8~kg} \\\\\boxed {\sf a = 1.5~ \frac{m}{s^2} }

Capacitor C1 is initially charged to V1 and capacitor C2 is initially charged to V2. The capacitors are then connected to each o
disa [49]

Answer:

ΔV = 20.1 V

Explanation:

As the positive plates are connected to each other, the capacitors are connected in parallel, so the total system load is the sum of the charges on each capacitor.

               Q = Q₁ + Q₂

                 

The charge on each capacitor is

            Q₁ = C₁ ΔV₁

            Q₁ = 24 10⁻⁶ 25

            Q₁ = 6.00 10⁻⁴ C

            Q₂ = C₂ ΔV₂

            Q₂ = 13 10⁻⁶ 11

            Q₂ = 1.43 10⁻⁴ C

The total set charge is

            Q = (6 + 1.43) 10⁻⁴

            Q = 7.43 10⁻⁴ C

The equivalent capacitance is

           C_eq = C₁ + C₂

           C_eq = (24 + 13) 10⁻⁶

           C_eq = 37 10⁻⁶ F

Let's use the relationship to find the voltage

          Q = C_eq ΔV

          ΔV = Q / C_eq

          ΔV = 7.43 10⁻⁴ / 37 10⁻⁶

          ΔV = 2.008 10¹

          ΔV = 20.1 V

This voltage is constant in the combination so it is also the voltage in capacitor C1

The support at the left end of the beam will fail if the moment about A of the 15-kN force F exceeds 18 kN-m. Based on this crit
Serga [27]

Answer:

2.4 m

Explanation:

We are given that

Maximum moment about A=18 kN m

Force=15 KN

\theta=30^{\circ}

We have to find the largest allowable length of the beam

Let larges length of beam=L

Moment about A

M=LFsin 30=L(15)sin 30=7.5 LkN m

According to question

M=M_{max}

7.5 L=18

L=\frac{18}{7.5}=2.4 m

Hence, the largest length of the beam=2.4 m

Plssss help quick <br>Why does a fast moving person feel heavier than normal? ​
vovangra [49]

Answer:

So, if you move faster, and as you move faster, you generate more Electromagnetic Energy, then as you move faster, you push more Dark Energy away from yourself! And Dark Energy pushes harder against you, so you get heavier! So, if you move FAST, your time slows down!
