The digit with the least amount of confidence can be seen in the second part which is 7.
The number of significant figures in the measurement of the stopwatch is 4.
An elapsed time is the difference between the time prior to the commencement of an event and the time at which the event has ended.
From the stopwatch, the elapsed time is given as:
0hour : 13 minutes : 37 seconds
The digit with the least amount of confidence can be seen in the seconds part is 7.

Answer:
Given that refractive index of the material is √2. i.e. n = √2. Hence, critical angle for the material is 45°
At constant temperature and volume the pressure of a gas is directly proportional to the number of moles of the gas. PV =n RT, where R is the universal gas constant. A change in pressure depends with the number of moles of the gas, such that if the number of moles increases then there are many vibrations and collision of the gas molecules with the walls of a container thus increasing the pressure and vice versa.
Answer:
100 J
Explanation:
Given:
Force acting on the crate is, 
Displacement of the crate is, 
Angle between the direction of force and displacement is, 
Now, work done by a force 'F' causing a displacement 'S' such that the angle between the force and displacement is 
is given as:
Now, plug in 100 N for 'F', 2 m for 'S', and 60° for . This gives,
Therefore, the work done by the force is 100 J.
Each station has a circle made of possible epicenters. When you have atleast 3 epicenters you can narrow it down to 1 epicenter and there's that final point. Each station can detect how far away the epicenter was (by transverve body waves). When you only have one seismic station it's impossible to locate an earthquake epicenter.
