The reaction of reduction always undergoes with the cathode, the positive ion will migrate towards the cathode with the negative charge whilst the anode always has oxidation reaction. These two types of reaction does not change.

Answer:

the cathode, which is negatively charged

Explanation:

In an electrolytic cell, there are two electrodes; the anode and the cathode. The anode is positively charged while the cathode is negatively charged.

Oxidation occurs at the anode as the positive ions loose electrons. The electrons lost at the anode travels via a conductor to the cathode. Positive ions migrate to the cathode, accept these electrons and become reduced.

If the Hubble Space Telescope is 598 m above the surface of the Earth and is traveling at 7.56 x 103 m/s, how long does it take
viva [34]

Answer:

5069.04 seconds

Explanation:

The parameter we are looking for is called the Orbital period of the Hubble Space Telescope.

It is given as:

T = \sqrt{\frac{4\pi^2r^3 }{GM} }

where r = radius of orbit of Hubble Space Telescope

G = gravitational constant = 6.67408 * 10^{-11} m^3 kg^{-1} s^{-2}

M = Mass of earth

We are given that:

r = radius of the earth + distance of HST from earth

r = 6.38 * 10^6 + 598 = 6380598 m

M = 5.98 * 10^{24} kg

Therefore, T will be:

T = \sqrt{\frac{4*\pi^2 * 6380598^3 }{6.67408 * 10^{-11} * 5.98 * 10^{24}}}

T = 5069.04 secs

The orbital period of the Hubble Space Telescope is 5069.04 seconds.

An airplane is flying through the air at a speed of 150 mph at a heading of 60 degrees. if the wind is blowing at 20 mph from th
Crazy boy [7]

Answer:

Explanation:

Given

speed of plane 150 mph

heading 60^{\circ}

wind is blowing at 20 mph from south-east

velocity of plane w.r.t. wind

v_{pw}=150(\cos 60\hat{i}+\sin 60\hat{j})

v_{w}=20(\cos 45\hat{i}-\sin 45\hat{j})

v_{p}=v_{pw}+v_{w}

v_{p}=(150\cos 60+20\cos 45)\hat{i}+(150\sin 60-20\sin 45 )\hat{j}

v_{p}=89.14\hat{i}+115.76\hat{j}

|v_{p}|=146.103 m/s

(b)after 30 minutes

Plane traveled in  x direction =89.14\times 0.5=44.57 miles

Plane in Y direction =115.76\times 0.5=57.88 miles

Total distance=\sqrt{x^2+y^2}=73.05 miles

direction tan\theta =\frac{115.76}{89.14}=1.298

\theta =52.38^{\circ} w.r.t east

An automobile tire having a temperature of −1.6 ◦C (a cold tire on a cold day) is filled to a gauge pressure of 22 lb/in2 . What
r-ruslan [8.4K]

Answer:

25.8 lb/in²

Explanation:

Gay-Lussac's law tells us that given an ideal gas of a certain mass has a constant volume, the pressure exerted on the sides of its container is directly proportional to its absolute temperature.

\frac{P_{1} }{T_{1} } = \frac{P_{2} }{T_{2} } \\\\\frac{22}{-1.6+273.15} =\frac{P_{2} }{45+273.15} \\\\P_{2} = \frac{22*318.15}{271.55} = 25.8lb/in^{2}
