<h2>
The acceleration of gravity at the location is 9.64 m/s²</h2>
Explanation:
Length of pendulum = 2.5 m
Time taken for 5 swings = 16 seconds
Time taken for 1 swing = 3.2 seconds
Period of pendulum = 3.2 seconds.
We have equation for period of simple pendulum as
Where l is the length of pendulum and g is acceleration due to gravity.
Substituting
The acceleration of gravity at the location is 9.64 m/s²
Answer:
the faster an object moves the more kinetic it has. the more mass an object has, the more kinetic energy it has.
Answer:
877
Explanation:
P1 = 150 atm
V1 = 0.12 m^3
P2 = 1.2 atm
V2 = ?
radius of each balloon, r = 0.16 m
Volume of each balloon,
V2 = 0.0171 m^3
Let the number of balloons be N.
So,
P1 x V1 = N x P2 x V2
150 x 0.12 = N x 1.2 x 0.0171
N = 877.19
So, the number of balloons be 877.
