N=3,1=2ml,0ms= +1/2 this is your answer
Answer: 62.7
Explanation:
The specific heat capacity of water is 4.186 J you multiply 4.186 and 15.0 and you will get 62.7
Answer:
0.248 m
Explanation:
The period of a simple pendulum is given by
where
L is the length of the pendulum
g is the acceleration of gravity
The pendulum in the problem passes its lowest point twice every second: this means: this means that it makes one complete oscillation in one second, so its period is 1 second:
T = 1 s
And using
We can rearrange the equation above to find L, the length of the pendulum:
Force = mass x acceleration
113N = 25.2a
a = 4.48 m/s^2
Vf = Vi + at
Vf = 2.33 + 4.48(2) = 11.3 m/s
