Answer:
C) 1 s
Explanation:
The period of a mass-spring system is given by the formula:
where
m is the mass hanging on the spring
k is the spring constant
As we can see from the equation above, the period of the system does NOT depend on the initial amplitude of the oscillation. Therefore, even if the initial amplitude is changed from 5 cm to 10 cm, the period of the system will remain the same, 1 s.
Answer:
135 N
Explanation:
Given that:
In a tug of war, team A pulls the rope with a force of 225 N; &
Team B also pulls with a force of 360 N
The magnitude of the resultant force is the difference between the two forces since they are positioned in the opposite direction.
Thus;
The magnitude = 360 N - 225 N
So, magnitude of resultant force on the rope = 135 N
Ok so this is a kinetic and potential energy problem. KE= 1/2*m*v^2 and PE= mgh so we set them equal to each other and get KE=PE so 1/2mv^2=mgh so mass divers out and left with 1/2v^2 =gh so solving for h or height we get
h=(1/2v^2)/g so h= 1/2*(6.5m/s)^2/9.80m/s^2 = 2.16m in height the ball will reach.
Hope this helps! Any questions please just ask!
Please rate to help me out also! Thank you so much!!!
Answer:
Β. 16 με
Explanation:
Data provided in the question
Number of electrons removed = 10^14
And, the charge on one electron = 
Based on the above information, the charged on the sphere is
Therefore when we remove the electrons
So, the equation would be
= 
Therefore the same amount of the positive charged would be developed
Hence, the correct option is B.
Answer:
Acceleration:
C. Meters per second squared
Velocity:
B. Meters per second
Distance:
A. Meters
Explanation:
We must remember that the international system of measures (SI) takes into account for the length as the main unit the meter, for the mass the kilogram, for the time the second.
The acceleration is calculated using the following expression
a = v/t = (m/s/s) = (m/s^2]
The velocity is calculated using the following expression
v = x/t = (m)/(s) = (m/s)
The distance for the SI system is given in meters
