<span>Standard deviation is a calculation. It I used in statistical analysis of a easier job. hoped this helps u </span>
Answer:
No - It is connected in parallel instead of series
Explanation:
Answer:
Explanation:
The vehicle is experiencing a large force created by the concrete wall.
Equation
vf^2 = vi^2 + 2*a * d
Givens
vf = 0 The car eventually does stop.
vi = 72 km/hr * [ 1000 m/ km] * [1 hour / 3600 seconds]
vi = 20 meters / second
a = ?
m = 850 kg
Solution
vf^2 = vi^2 + 2a*d
0 = 20 m/s + 2* 2 *a
-20 m/s = 4a
-20/4 = a
a = - 5 m/s^2 The minus sign tells you the vehicle is slowing down. It sure should be.
Force = m * a
F = - 850 * (-5)
F = - 4250 N
The car provides a 4250 N force on it going east to west and a 4250 N force going from west to east provided by the concrete wall.
Answer:
b. less than
Explanation:
Moment of inertia decreases as angular velocity increases. Therefore, since the minute hand is faster than the hour hand, it is safe to say that the moment of inertia of the minute hand is less than the moment of inertia of the hour hand?
The answer is B because it literally says it right there, and I don't wanna make it impossibly confusing for a middle school student, lol.
