sertanlavr [38]

Initial launch velocity, u = 0
Acceleration, a = 300 m/s²
Duration, t = 8.0 s

The distance traveled is
h = ut + (1/2)*a*t²
= (0 m/s)*(8 s) + 0.5*(300 m/s²)*(8 s)²
= 9600 m

Answer: 9600 m

Plzzzzzzzz helppppp plzzzzzz

Answer:

As the sun warms the land, the air above the land warms too. The warmer, lighter air rises, and the cooler heavier air above the water moves in and replace the rising warm air

Explanation:

In convection current, during a hot sunny day, the land is heated up and the air above the land becomes warm and rises upward because of their low density. The cool breeze from the sea with higher density moves downward to replace the risen warm air. This process is known sea breeze which happens in the day time.

Based on the given options, we can choose the first option.

"As the sun warms the land, the air above the land warms too. The warmer, lighter air rises, and the cooler heavier air above the water moves in and replace the rising warm air".

What is the equivalent resistance of the

BigorU [14]

Answer:

Approximately $111\; {\rm \Omega}$ .

Explanation:

It is given that $R_{1} = 200\; {\Omega}$ and $R_{2} = 250\; {\Omega}$ are connected in a circuit in parallel.

Assume that this circuit is powered with a direct current power supply of voltage $V$ .

Since $R_{1}$ and $R_{2}$ are connected in parallel, the voltage across the two resistors would both be $V$ . Thus, the current going through the two resistors would be $(V / R_{1})$ and $(V / R_{2})$ , respectively.

Also because the two resistors are connected in parallel, the total current in this circuit would be the sum of the current in each resistor: $I = (V / R_{1}) + (V / R_{2})$ .

In other words, if the voltage across this circuit is $V$ , the total current in this circuit would be $I = (V / R_{1}) + (V / R_{2})$ . The (equivalent) resistance $R$ of this circuit would be:

$\begin{aligned} R &= \frac{V}{I} \\ &= \frac{V}{(V / R_{1}) + (V / R_{2})} \\ &= \frac{1}{(1/R_{1}) + (1 / R_{2})}\end{aligned}$ .

Given that $R_{1} = 200\; {\Omega}$ and $R_{2} = 250\; {\Omega}$ :

$\begin{aligned} R &= \frac{1}{(1/R_{1}) + (1 / R_{2})} \\ &= \frac{1}{(1/(200\: {\rm \Omega})) + (1/(250\; {\rm \Omega}))} \\ &\approx 111\; {\rm \Omega}\end{aligned}$ .

Why are understandings of patterns so important to human development?

andrew11 [14]

Patterns provide a sense of order in what might otherwise appear chaotic. Researchers have found that understanding and being able to identify recurring patterns allow us to make educated guesses, assumptions, and hypothesis; it helps us develop important skills of critical thinking and logic

A power plant uses 365 GJ/hr of energy from a boiler and extracts 18 GJ/hr as work from a turbine and rejects the remaining ener

ziro4ka [17]

Answer:

The rate of heat rejection will be 347 GJ/hr

Explanation:

We have given that power plant uses energy of 365 GJ/hr

So energy uses $Q_B=365GJ/hr$
