A hot-air balloonist, rising vertically with a constant speed of 5.00 m/s releases a sandbag at the instant the balloon is 40.0

m above the ground. After it is released, the sandbag encounters no appreciable air drag. Compute the position of the sandbag at 0.250 s after its release.

Answer:

Y = 40.94m

Explanation:

The initial speed of the sandbag is the same as the balloon and so is its position, so:

$Y = Yo + Vo*t-\frac{g*t^2}{2}$

Replacing these values:

Yo = 40m Vo = 5m/s g = 9.81m/s^2 t = 0.25s

We get the position of the sandbag:

$Y = 40+5*(0.25)-\frac{9.81*(0.25)^2}{2}$

Y = 40.94m

You attach a meter stick to an oak tree, such that the top of the meter stick is 1.87 meters above the ground. Later, an acorn f

Verdich [7]

To solve this problem we will apply the concepts related to the kinematic equations of linear motion. We will calculate the initial velocity of the object, and from it, we will calculate the final position. With the considerations made in the statement we will obtain the total height. Initial velocity of the acorn,

$u = 0m/s$

Also, it is given that the acorn takes 0.201s to pass the length of the meter stick.

$s = ut+\frac{1}{2} at^2$

Replacing,

$1 = u(0.141)+ \frac{1}{2} (9.8)(0.141)^2$

$u =6.4013m/s$

The height of the acorn above the meter stick can be calculated as,

$v^2 = u^2 +2gh$

$h = \frac{v^2-u^2}{2g}$

$h = \frac{6.4013^2-0^2}{2(9.8)}$

$h = 2.0906m$

Also the top of the meter stick is 1.87m above the ground hence the height of the acorn above the ground is

$h = 2.0906+1.87$

$h = 3.9606m$

When power and current are known use R = P/I^2 to calculate the resistance.

inna [77]

<h2> $\bf{ \underline{Given:- }}$ </h2>

$\sf• \: Power \:( P) = 300 \: watts$

$\sf• \: Current \: (I) = 30 \: amps$

$\\$

<h2> $\bf{ \underline{To \: Find:- }}$ </h2>

$\sf• \: The \: Resistance$

$\\$

$\huge\bf{ \underline{Solution :-:- }}$

$\bf \red {\bigstar{ Formula \: of \: Power \: (P) = \frac{ {I}^{2} }{R}}}$

$\sf \rightarrow 300= \frac{ {30}^{2} }{ R}$

$\sf \rightarrow 300 = \frac{900}{ R}$

$\rightarrow \sf R = \frac{300}{900}$

$\rightarrow \sf R = \frac{1}{3}$

$\rightarrow \sf R = 0.33$

What defines "the time of full wave"

eimsori [14]

Answer:

A) Periodic time

Explanation:

Wavelength is the distance from a point on a wave to the same point on an adjacent wave

Wave speed is the speed the wave is travelling at

Wave frequency is how many waves pass a fixed point in a given time period
