The answer is:
V = d/t d = 86 km t = 1.3 hrs
V = 86 km/ 1.3 hrs
V = 66.15 km/ hrs
I hope this helps!!
Answer: The average speed is 27,24 mph (exactly 1008/37 mph)
Explanation:
This is solved using a three rule: We know the speeds and the distances, what we can obtain from it is the time used. It is done like this:
1h--->18mi
X ---->20 mi, then X=20mi*1h/18mi= 10/9 h=1,111 h
1h--->56mi
X ---->20 mi, then X=20mi*1h/56mi= 5/14 h=0,35714 h
Then the average speed is calculated by taking into account that it was traveled 40mi and the time used was 185/126 h=1,468 h and since speed is distance over time we get the answer. Average speed= 40mi/(185/126 h)=1008/37 mph=27,24 mph.
Answer:
The big rip theory
Explanation:
I believe what you are referring to is the big rip theory, in which the universe expands faster than the speed of light Kurzgesagt refers to it as a "horizon" but in reality it's a little more complicated than that. Eventually the expansion of the universe will accelerate far beyond the speed of light creating space between molecules until eventually all matter is fleeting and the entire universe is an endlessly vast cosmic void with not but the occasion molecule left from a time when things weren't so lonely.
Answer:10 A
Explanation:
According to the KCL (Kirchhoff's current laws)
Answer:
Force=29789.55 N
Explanation:
Given data
dimension=3.5m by 2.1m
P(outside pressure)=0.96 atm
P(inside pressure)=1.00 atm
Force=?
Solution
Area=L×W
A=(3.5)×(2.1)
As we know
F=PA
For P(pressure)
P=P(inside)-P(outside)
P=1.00-0.96
P=0.04 atm
convert atm to pascal (pa) we get
P=4053 pa
F=PA
F=(4053)×(7.35)
F=29789.55 N
