Time period depends on the length of the pendulum and the force of gravity.
<h3>On what things time period depends?</h3>
The time period of a simple pendulum does not depend on mass and material of the bob. It depends on the length of the pendulum and the force of gravity because more length of the pendulum leads to more time to complete one cycle.
So we can conclude that time period depends on the length of the pendulum and the force of gravity.

Acceleration is the rate of change of the velocity of a moving object. To determine the speed the object has at a certain time, we need to determine the acceleration first by dividing the speed with the time given. We do as follows:
acceleration = 4.9 m/s / 5.1 s = 0.96 m/s^2
To determine the velocity after 7.1 s, we multiply 7.1 s to the acceleration.
speed or velocity = 0.96 x 7.1 = 6.52 m/s
Answer:
length=2
Explanation:
You simply find the zeros of the quartic polynomial
The factored form is (x+1)(x-5)(x-2)=0
The zeros become -1,5 and 2
Dimension 5 is already given and the question says length>width and 2>-1
Therefore length=2
Answer:
The efficiency of a Stirling engine is 74%
Explanation:
Given:
Temperature of gas when it is cold
K
Temperature of gas when it is hot
K
The efficiency of a stirling engine,




∴ 
Therefore, the efficiency of a Stirling engine is 74%
Answer:
62.5 miles per hour
Explanation:
Speed = Distance travelled / Time taken
Speed = 125/2 = 62.5
You derive the units of the speed...by using the speed formula....,
Speed = Distance/Time
Speed = miles/hour
Hence the units for the speed = miles/hour
