STatiana [176]

Answer:

<h3>The answer is 30.43 L</h3>

Explanation:

The new volume can be found by using the formula for Boyle's law which is

$P_1V_1 = P_2V_2$

Since we are finding the new volume

$V_2 = \frac{P_1V_1}{P_2} \\$

From the question we have

$V_2 = \frac{35000 \times 80}{92000} = \frac{2800000}{92000} = \frac{700}{23} \\ = 30.434782...$

We have the final answer as

Hope this helps you

An airplane is flying at a speed of 45 m/s when it drops a 40 kg food package to the Polar exploration team. If the plane drops

Alina [70]

To solve this problem we will apply the concepts related to energy conservation, so the potential energy in the package must be equivalent to its kinetic energy. From there we will find the speed of the package in the vertical component. The horizontal component is given, as it is the same as the one the plane is traveling to. Vectorially we will end up finding its magnitude. So,

$PE = KE$

$mgh = \frac{1}{2}mv^2$

Here,

m = Mass

g = Gravity

h = Height

v = Velocity

Rearranging to find the velocity

$v = \sqrt{2gh}$

Replacing,

$v = \sqrt{2(9.8)(120)}$

$v = 48.49m/s$

Using the vector properties the magnitude of the velocity vector would be given by,

$|V| = \sqrt{v_x^2+v_y^2}$

$|V| = \sqrt{45^2+48.42^2}$

$|V| = 66.2m/s$

Therefore the package is moving to 66.2m/s

If something is hot, does it contain heat or thermal energy?

zysi [14]

I am absolutely sure that if something is hot, it contain thermal energy only because <span>if a given body is heated its electrons start to move very fast which means that thermal energy is being produced. Hope everything is clear! Regards!</span>

How does the electric force between two charged objects on the charges of the objects

Mariulka [41]

Answer:

If one charged object is positive, and the other charged object is negative, then the two objects will attract each other. If both objects are positive, the objects will repeal each other. If both objects are negative, the objects will also repeal each other.
