Answer:
Rate of change of water will be -6 gallon/minute
Explanation:
We have given water in the tank as the function of time as
We have to find the rate of change of water in the tank at t = 3 minute
For rate of change we have to differentiate both side
So
At t = 3 minute
Answer:
temperature on left side is 1.48 times the temperature on right
Explanation:
GIVEN DATA:
T1 = 525 K
T2 = 275 K
We know that
n and v remain same at both side. so we have
..............1
let final pressure is P and temp
..................2
similarly
.............3
divide 2 equation by 3rd equation
thus, temperature on left side is 1.48 times the temperature on right
Explanation:
(a) Displacement of an object is the shortest path covered by it.
In this problem, a student is biking to school. She travels 0.7 km north, then realizes something has fallen out of her bag. She travels 0.3 km south to retrieve her item. She then travels 0.4 mi north to arrive at school.
0.4 miles = 0.64 km
displacement = 0.7-0.3+0.64 = 1.04 km
(b) Average velocity = total displacement/total time
t = 15 min = 0.25 hour
Hence, this is the required solution.
