The velocity of a projectile at launch has a
arlik [135]

Answer:

1. 0 vh g

Explanation:

As air resistance is negligible, horizontal speaking, nothing is affecting the velocity. So the horizontal velocity of the projectile stays the same, vh.

As for vertical velocity, since there's always a constant gravitational acceleration acting downward, namely g, the vertical speed will decrease until it reaches the top where it is 0, it then starting to increase in magnitude, downward, due to its gravitational acceleration g.

The free-body diagram below represents the force of several vehicles driving across a bridge. Assume that the bridge is in stati
krek1111 [17]

In order to calculate the unknown reaction force, we need to know that the sum of forces pointing down is equal the sum of the forces pointing up, so all forces will be in equilibrium.

So we have:

\begin{gathered} 17800+150000+13200=121000+x \\ 181000=121000+x \\ x=181000-121000 \\ x=60000 \end{gathered}

An especially violent lightning bolt has an average current of 1.89 x 103 A lasting 0.133 s. How much charge is delivered to the
Rasek [7]
<h2> Charge = 25.9 Ampsec^{-1}</h2>

Explanation:

Given,

The average current (I) = {1.89} \times {103 A} and

Time period (T) = 0.133 s

The charge is calculated by multiplying the current to the time period.

Hence,

To find, the charge delivered to the ground by the lightning bolt(Q) = ?

By applying the formula of charge that is-

Charge(Q) = Current(I) \times Time(T)

∴ Charge(Q) = {1.89} \times {103 A}\times 0.133 s

= 25.89111 As^{-1}

= 25.9 As^{-}

<h3>Thus, the charge of 25.9 Ampsec^{-1} is delivered to the ground by the lightning bolt.</h3>
