Newton's second law of motion. F = m a .
B. Tolerating a bully or dictator leads to further abuse
Answer:
Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position
Explanation:
change it up a bit if you're worried about it being copy/pasted
Answer:
r = 1.07 m
Explanation:
The maximum radius of the propeller that can be allowed is given by the following formula:

where,
r = maximum possible radius of the propeller = ?
v = maximum possible linear speed of the propeller = 270 m/s
ω = angular speed of the propeller = (2400 rpm)(2π rad/1 rev)(1 min/60 s)
ω = 251.33 rad/s
Therefore,

<u>r = 1.07 m</u>
Density = Mass/Volume
2.5 g/ml = 5g/Volume
Volume = 5g/(2.5 g/ml)
= 2 ml
