<span>Is the following sentence true or false? Newton's first law does object's mass concentration and its axis of rotation increases, its rotational inertia The bicycle wheels at rest have no angular momentum, and the bicycle will fall over easily.</span><span>

Explanation:
everything can be found in the picture
Add the KE increase and the work done against friction.
The final velocity is twice the average, or 3.0 m/s
The final KE is (1/2)*25*3^2 = 112.5 J
The friction work done is 6*3.8 = 22.8 J
hope this is correct
Correct me if I’m wrong but I think it’s A
Explanation:
Runner A has already reached about 50m in around 5s.
Answer:
211 mmHg
Explanation:
Absolute Pressure = Gauge Pressure + Atmospheric pressure
128 = Gauge Pressure + 100
Gauge Pressure = 28 KPa = 28 × 10³ Pa
Also Gauge Pressure = ρgh
ρ = density = 13550 kg/m³
g = acceleration due to gravity = 9.8 m/s²
h = pressure head = ?
28 × 10³ = 13550 × 9.8 × h
h = 28000/(13550 × 9.8)
h = 0.211 m = 211 mm
