Answer:

Solstice usually refers to the condition when there occurs the longest duration of day and night and during this time the north pole of the earth is tilted at the farthest distance from the location of the sun. There are two types of the solstice, namely the summer and the winter solstice.

In the case of the northern hemisphere or the upper half of the equator, the summer solstice usually occurs in June 21st and the winter solstice occurs in December 21st.

The locations on earth where the sunlight is directly incident during the time of summer solstice are the regions lying in the tropic of cancer namely, India, Mexico, the southern portion of China and the Bahamas.

so i did this thing and idk how it happened but basically i put foil inside the tip of my computer charger while it was charging

just olya [345]

Answer:

It was most likely static electricity

Explanation:

Static electricity comes down to the interactive force between electrical charges.

So because your computer charger has electricity the foil is a conductor so the sparks were most likely static electricity

A spring stores potential energy U0 when it is compressed a distance x0 from its uncompressed length.

beks73 [17]

Answer:

Explanation:

Using Hooke's law

Elastic potential energy = 1/2 K x²

K is elastic constant of the spring

x is the extension of the spring

a) The elastic potential energy when the spring is compressed twice as much Uel = 1/2 k (2x₀) ² = 4 (1/2 kx₀²)= 4 U₀

b) when is compressed half as much Uel = 1/2 k $\frac{x0}{4} ^{2}$ = $\frac{1}{4}$ ( U₀)

c) make x₀ subject of the formula in the equation for elastic potential

x₀ = $\sqrt{\frac{2U0}{K} }$

x, the amount it will compressed to tore twice as much energy = $\sqrt{\frac{2 (2U0)}{K} }$

x = √2 x₀

d) x₁, the new length it must be compressed to store half as much energy = $\sqrt{\frac{2 (\frac{1}{2})U0 }{K} }$

x₁ = $\sqrt{\frac{1}{2} }$ x₀

Consider a car engine running at constantspeed. That is, the crankshaft of the en-gine rotates at constant angular velocity whil

Irina-Kira [14]

Answer:

The value is $|v| = 7.39 \ m/s$

Explanation:

From the question we are told that

The angular speed is $w = 2030 \ rpm = \frac{2030 * 2 * \pi }{ 60} = 212.61 \ rad/s$

The distance between the minimum and maximum external position is $d = 6.95 \ cm = 0.0695 \ m$

Generally the amplitude of the crank shaft is mathematically represented as

$A = \frac{d}{2}$

=> $A = \frac{0.0695}{2}$

=> $A = 0.03475 \ m$

Generally the maximum speed of the piston is mathematically represented as

$|v| = A * w$

=> $|v| = 0.03475 * 212.61$

=> $|v| = 7.39 \ m/s$
