_______________
h=7,5 m
g=10 m/s²
ρ=1000 kg/m³
_______________
p - ?
_______________
p=ρgh=1000 kg/m³ · 10 m/s² · 7,5 m = 75000 Pa = 75 kPa
The digestive system digests and makes nutrients out of food while the circulatory system distributes and circulates the nutrients i believe?
Answer:
Average speed, v = 25 m/s
Explanation:
It is given that,
Distance travelled by the object, d = 50 meters
Time taken, t = 2 seconds
Average speed is defined as the total distance divided by total time taken i.e.
v = 25 m/s
So, the sped of the object is 25 m/s. Hence, this is the required solution.
The scalar operates only on the magnitude of the vector.
So the length of the vector may change ... becoming longer
or shorter ... but its direction doesn't change.
Okay. I'm willing to do that. But first you'll have to tell me something about the sample in question 3.
