Answer:
The force is of the weight <u>862,4 Newtons.</u>
<u></u>
Explanation:
We have the formula:
w = m * g
Data:
w = weight = ¿?
m = mass = 88 kg
g = gravity = 9,8 m/s
Replacing according formula:
w = 88 kg * 9,8 m/s
Resolving:
w = 862,4 N
Multiply by the fraction (1 kg/1000 gm).
Answer:
T = 3.475 s
Time period is independent from mass
Explanation:
- To reduce the human error in taking any measurements we take multiple N number of readings. Then sum up all the readings and divide by N to find an average. The error between each individual reading and the actual reading is reduced by repetition.
- We use the plot of T^2 against L to form a linear relationship between two variables. We square the entire the equation for linearize the equation.
- Given, L = 3 m . The time period is approximated by a pendulum expression given as:
T = 2*pi*sqrt ( L / g )
Where, g is the gravitational acceleration 9.81 m/s^2
- Then we have:
T = 2*pi*sqrt ( 3 / 9.81 )
T = 3.475 s
- From above expression we see that time period is independent from the mass at the end of the string but a function of pendulum geometry and kinetics.
The change in internal energy that accompanies the transfer of heat, q, or work, w, into or out of a system can be calculated using the following equation: Note the value of heat and work as they are transferred into or out of a system.
Deceleration = 29250 / 6500 = 4.5 m/s^2
