<h2>Answer:</h2>
At 30 C, exactly 95 grams of this salt dissolved completely in 100 grams of water. According to the solubility chart, the salt is Sodium niatrate NaNo3
Every single metallic nitrate are inorganic salts of a given metal cation and the nitrate anion. The nitrate anion is a univalent (- 1 charge) poly atomic particle made out of a solitary nitrogen iota ionically bound to three oxygen molecules for an all out equation load of 62.05. Nitrate mixes are commonly solvent in water.
Answer:
Explanation:
given,
velocity of particle 1 = 0.741 c to left
velocity of second particle = 0.543 c to right
relative velocity between the particle = ?
for the relative velocity calculation we have formula
u_x = 0.543 c
v_x = - 0.741 c
Relative velocity of the particle is
The frequency of a wave is just the reciprocal of the period.
For this one . . .
Frequency = 1/(period) = 1/(5 sec) = 0.2 per sec (0.2 Hz) .
There is a missing data in the text of the problem: the current drawn is 0.5 A (found on internet)
Solution:
The power used by the toaster is the product between the voltage V and the current I:
The toaster is used for a time of 2 hours: t=2h, therefore the energy used is equal to
By conducting exhaustive, high-intensity online research for about 15 seconds, I found a source that says the speed of sound in copper is 4600 m/s. (You could easily have completed the same research project in about 1/3 of the time it took you to type and post the question here.)
Time it takes = (distance) / (speed)
Time = (25,000 meters) / (4600 m/s)
Time = (25 / 4.6) km-sec/km
<em>Time = 5.43 seconds </em>
