Explanation:
If the fourth pupil has a mass of x, and the fifth pupil has a mass of x+5, then the mean mass is:
51 = (49 + 53 + 52 + x + x+5) / 5
255 = 159 + 2x
x = 48
x + 5 = 53
The fourth pupil has a mass of 48 kg.
The fifth pupil has a mass of 53 kg.
Answer:
1.1mg/min
Explanation:
We are given that
Volume of solution=250 ml
Mass of amiodarone=1 g
Infusion rate=17 ml/hr
We know that
1 g= 1000 mg
Ratio of 1000g:250 ml=
The concentration of solution=4mg/ml
Amiodarone infusing (mg/min)=
Because 1 hr= 60 minute
Amiodarone infusing=1.1mg/m
Hence, 1.1 mg/min of amiodarone is infusing.
Answer:
Action and reaction are equal but act in opposite directions
Answer:
Explanation:
Acceleration of gravity on the surface of
Neptune is given
g' = G M/R^2,
where M is the planet's mass.
M g' will be the apparent weight registed at the poles.
G is the universal constant of gravity
The "apparent weight" at the equator will be
reduced from M g' by the centripetal force M
R w^2, where w is the rotational angular
velocity in radians/s), which you can deduce
from the 16 hour length of a day.
Answer:29.4m/s
Explanation: Vf=Vi +at= 0 initial velocity +(9.8)(3)= 29.4 m/s
