Complete question is;
A bicycle and a car start their journey at the same time the cyclist reaches it's top speed of 10m/s in 15 s, the car reaches a speed of 15 m/s in 55 s. which has the greater acceleration the car or the bicycle.
Answer:
The bicycle has the greater acceleration.
Explanation:
Cyclist reaches a top speed of 10m/s in 15 s.
Formula for acceleration here is;
a = v/t
a = 10/15
a = 0.67 m/s²
Car reaches a speed of 15 m/s in 55 s.
Thus;
a = 15/55
a = 0.27 m/s²
From the 2 acceleration values gotten, we can say that;
The bicycle has the greater acceleration.
Answer:
A. Using
Pgauge= Pmanometer
And we know that
Pgauge= deta(hpg)
So deta h = Pgauge/density x g
So
= 7.5(6894.76/1psig)/ 13.6*10^3*9.8m/s²)
= 387.9mm
So to find height of pipe connected to the pipe we say
= h -deta h
= 900-387.97mm
=512.02mm
B. We use manometry principle
Pgas+density xg(25*10^3)-PX density{h-(H-0.25)=0
So
Finally Pgas= 6.54psig
The answer is The Law of Conservation of Energy, hope this helps.

Answer:
<h3>The answer is 10 m/s</h3>
Explanation:
The velocity of the object can be found by using the formula

p is the momentum
m is the mass
From the question we have

We have the final answer as
<h3>10 m/s</h3>
Hope this helps you
The correct answers should be<span> the hares will multiply indiscriminately and destroy the ecosystem and </span><span>the native herbivores will experience increased competition for resources.
Since the hares wouldn't have predators, and they are famous for rapid breeding, they would overpopulate the ecosystem. On the other hand, the native animals would have to compete with this population of hares for food and would have less for for themselves.</span>
