Answer:
107 kJ
Explanation:
12.00 kg * 913 J /kg-C * (118-20)°C ( I corrected spec heat units)
( a C degree change is the same as a kelvin change)
= 1 073 688 J = 107 kJ ( three sig digits)
Answer:
Obviously Lengthen... or
Explanation:
As we can observe from the equation, time period of a simple pendulum depends upon the length directly. When the gravitational acceleration increases the time period of the pendulum decreases and vice versa. So, by increasing the length, the time period can be adjusted...
A reference point would be something not on the ship which could be used to calculate distance traveled.
Answer: C.) A lighthouse on a nearby Island
Answer:
Angular momentum,
Explanation:
It is given that,
Radius of the axle,
Tension acting on the top, T = 3.15 N
Time taken by the string to unwind, t = 0.32 s
We know that the rate of change of angular momentum is equal to the torque acting on the torque. The relation is given by :
Torque acting on the top is given by :
Here, F is the tension acting on it. Torque acting on the top is given by :
So, the angular momentum acquired by the top is . Hence, this is the required solution.
