Answer:
So average speed of the earth in miles per hour will be equal to
Explanation:
We have given average speed of the earth v = 29783 km/sec
We have to convert this speed into miles per hour
For converting the speed in miles per hour first we have to convert km to miles and sec to hour
As we know that 1 km = 0.6213 miles
And 1 sec = 0.000277 hour
So
So average speed of the earth in miles per hour will be equal to

A concentrated acid is an acid which is in either pure form or has a high concentration. Laboratory type sulfuric acid (about 98% by weight) is a concentrated (and strong) acid.
A dilute acid is that in which the concentration of the water mixed in the acid is higher than the concentration of the acid itself. For instance, 5% sulfuric acid is a dilute acid.
A dilute acid, unlike a concentrated acid, will ionize to a greater degree in their solution (higher percent dissociation with decreasing concentration). However, if an aqueous acid mixture (such as sulfuric acid, mentioned above) is added to water, the resultant pH from adding a dilute one would be higher (lower acidity) than for a concentrated one.
Work depends on the force on the object and the displacement of the object.
