Answer:
The towers height is 322m
Explanation:
We can assume that a simple pendulum hangs from the top of the tower.
In this case, the length of the pendulum will be the same as the height of the tower.
We will use the next expression then:
Where T is the period, L is the pendulum length and g is the gravity 
From the previous expression we will have then that the length will be:
Replacing:
The towers height will be then: 322m
A person suffering from hyponatremia has too little sodium in the bloodstream. This condition appears when their is more amount of water as compared to solute. it is commonly caused by diarrhea, heart failure and liver disease. Person suffering from this condition must reduce the intake of water.
So the correct choice is

Answer:
Explanation:
The acceleration of the train is given by:
where:
u = 5 m/s is the initial velocity of the train
v = 45 m/s is the final velocity of the train
t = 8 s is the time taken for the train to increase the velocity
Substituting numbers into the formula, we find
Answer:
To save the unnecessary bills and carbon emissions.
Explanation:
Energy efficiency is important to society in the following ways:
1. It saves the unnecessary bills as buildings who are using energy efficiently have less demands.
2. Saving energy for the future generations as we know low demand would save the sources.
3. Energy efficiency is also important to society in environmental ways at efficient energy means low carbon emissions.
