Kinetic, potential because, at the top of the ramp it’s going faster. Potential at the bottom of the ramp is potential because, it’s not doing any motion.
Answer:
Net force = 800 – 650
= 150 N
150 = (800 ÷ 9.8) a
a = 1470 ÷ 800
= 1.8375 m/s^2, downwards
Answer: C
14.75g
Explanation:
Given that the half life time = 60.5s
Let No = initial mass = 59g
N = decayed mass
At time t = 0, No = 59g
At time t = 60.5s,
N = No/2 = 59/2
= 29.5g
At time t = 121
N = 29.5/2 = 14.75g
Therefore N = 14.75g
The altimeter reading is 29.17 from the Kollsman window is 29.17 in Hg
<h3>How to determine the
altimeter reading?</h3>
The given parameters are:
- Ground level = 700 ft i.e. the field elevation
- Pressure altitude = 1450 ft
The formula to calculate the pressure altitude is:
Altitude = (29.92 – Altimeter reading) * 1,000 + Ground level
Substitute the known values
1450 = (29.92 - Altimeter reading) * 1000 + 700
Evaluate the like terms
750 = (29.92 - Altimeter reading) * 1000
Divide both sides by 1000
0.75 = 29.92 - Altimeter reading
Evaluate the like terms
Altimeter reading = 29.17
Hence, the altimeter reading is 29.17 from the Kollsman window is 29.17 in Hg
