Bones are the correct answer.
Answer:
Therefore, the number of grams of salt in the tank at time t is 
Explanation:
Given:
Tank A contain
lit
Rate 
Dissolved salt
gm
Salt pumped in one minute is 
Salt pumped out is
of initial amount added salt.
To find 



Solving above equation,




Integrating on both side,

Add
on above equation,

Here given in question,


Put value of constant in above equation, and find the number of grams of salt in the tank at time t.

Therefore, the number of grams of salt in the tank at time t is 
Answer:
31.67 mph
Explanation:
To calculate the average speed of the truck, we must first obtain the total distance travelled by the truck followed by the total time taken for the truck to cover the distance travelled.
The following data were obtained from the question include:
Total distance) = 30 + 45 + 50 + 65 = 190 miles
Total time = 1 + 2 +1 +2 = 6 hours
Average speed =.?
Average speed = Total distance / Total time
Average speed = 190 /6
Average speed = 31.67 mph
Therefore, the average speed of the truck is 31.67 mph
Answer: Employments of friction based electricity incorporate contamination control, Xerox machines, and painting. They utilize the property that inverse electrical charges pull in. There are different utilizations including the properties of aversion and the making of electricity produced via friction flashes
friction based electricity is an awkwardness of electric charges inside or on the outside of a material. The charge stays until it can move away through an electric flow or electrical release.
In view of similar kinds of examinations like the one you performed, researchers had the option to set up three laws of electrical charges: Inverse charges pull in one another. Like charges repulse one another. Charged items pull in nonpartisan articles.
