Average speed equals distance divided by time. on a journey to the

Tanzania [10]

The average speed will be 2.38×10⁶ m/sec.The average speed of an object indicates the pace at which it will traverse a distance. The metric unit of speed is the meter per second.

<h3>What is the average speed?</h3>

The total distance traveled by an object divided by the total time taken is the average speed.

The speed calculated at any particular instant of time is known as the instantaneous speed.

Given data;

Distance travelled = 4.12x10¹⁶ meter

Time period= 1.73x10¹⁰ sec

The average speed is found as

$\rm V_{avg}= \frac{d}{t} \\\\\ \rm V_{avg}= \frac{4.12 \times 10^{16}}{1.73 \times 10^{10} } \\\\\ V_{avg}=2.38 \times 10^6 \ m/sec$

Hence, the average speed will be 2.38×10⁶ m/sec.

The compressor on an air conditioner draws 66.1 a when it starts up. the start-up time is about 0.388 s. how much charge passes

Ierofanga [76]

The current intensity is defined as the amount of charge flowing through a certain point of a wire divided by the time interval:
$I= \frac{Q}{\Delta t}$
where Q is the charge and $\Delta t$ is the time. Re-arranging the formula, we have
$Q=I \Delta t$

for the compressor in our problem, the intensity of current is I=66.1 A, while the time is $\Delta t= 0.388 s$ , so the amount of charge that crosses a certain point of the circuit during this time is
$Q=I \Delta t=(66.1 A)(0.388 s)=25.65 C$

Suppose the price elasticity of supply for gasoline in the short run is estimated to be 0.4. Due to an unexpected surge in the d

netineya [11]

Answer:

increase by 8 percent

Explanation:

<em>Price elasticity of supply of a product is the degree of responsiveness of supply of that product to a change in price.</em> Simply put:

Price Elasticity of supply = change in quantity supply/ change in price.

In this case, price elasticity of supply of gasoline = 0.4

Percentage price increase = 20 percent.

Hence,
