Freefall is when you don't have any control over your body, you have gravity pulling you down to the center of the earth, while weightlessness you have the ability to float, go down, move side to side. In weightlessness you have zero gravity, but while your freefalling you are in gravity.
Hope I was able to help!
The answer would be conformity. This is a kind
of social influence concerning a change in belief or conduct so one can fit in
with a group. This alteration is in reply to real (physical occurrence of
others) or fictional (pressure of social norms / prospects) group pressure.
The weight of a 73 kg person is
(73 kg)*(9.8 m/s²) = 715.4 N
When the plane accelerates upward, the inertial force acting on the person
(170 N) makes the person feel heavier.
Therefore the airplanes upward acceleration, a, is given by
(73 kg)*(a m/s²) = 170 N
a = 2.3288 m/s²
Answer: 2.329 m/s², upward.
Answer:
Explanation:
The kinetic energy of an object is , where is the mass of the object and is the velocity of the object.
The toy car's initial kinetic energy is .
After the child applies a 5N force on it in the same direction, its velocity will increase but its mass will stay the same.
To find the final velocity of the toy car, we can use kinematic equation
We are given and .
To find acceleration:
.
Now substitute into to get .
Using this, we can find the final kinetic energy of the toy car is .
Thus, the change in kinetic energy is (one significant figure).
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.
