on a newly discovered planet, the period of a pendulum with a length of 2 m is found to be 5 seconds. what is the acceleration due to gravity on this new planet?
T = 5s
L = 2m
Since T = 2.pai √L/g
=) (T/2π )^2 = L/g
=) g = L ( 2π/T)^2 = 2×4×3.143×3.143/25 = 3. 16m/s^2
=) g = 3.16m/s^2
Plz give a thumb up. Thank you.

The period of a simple pendulum in a grandfather clock on another planet is 1.80 s. What is the acceleration due to gravity on this planet if the length of the pendulum is 1.00 m.
If a fixed length simple pendulum is found to have three times the period on an unknown planet’s surface (compared to Earth), what is the acceleration due to gravity on that planet? Show your work.
13.11 A pendulum has a length of 4.8 m. a) At a location where the acceleration due to gravity is 9.80 m/s, what is the period of the pendulum? b) If the period of a pendulum is twice as much the value found in part a, what is the length?
You are preparing some apparatus for a visit to a newly discovered planet Caasi having oceans of glycerine and a surface acceleration due to gravity of 4.80 m/s2. If your apparatus floats in the oceans on earth with 47.0% of its volume submerged, what percentage will be submerged in the glycerine oceans of Caasi? ____ %
A pendulum consists of a mass of 2 kg hanging from a massless string of length 1.1 m. It is being used on another planet. If the period of the pendulum is 1 s, what is the acceleration due to gravity on that planet, in units of m/s-2? Select one: a. 43 b. 87 c. 1.1 d. 11 e. 0.023
When a pendulum with a period of 2.00000 s is moved to a new location from one where the acceleration due to gravity was 9.80 m/s2, its new period becomes 1.99900 s. By how much does the acceleration due to gravity differ at its new location? Incorrect: Your answer is incorrect. How is the period of the pendulum related to the length of the pendulum and the acceleration due to gravity at the location of the pendulum? What happens to...

What is the period and frequency of the pendulum’s motion? (Time on the graph which is on the x axis is in seconds) b. At what times will the pendulum be at its equilibrium point? c. What is the acceleration due to gravity on the surface of the...
1. If placed at the surface of Earth, a physical pendulum has a period of 1.8 seconds. What will be the period of the same pendulum at the surface of the Moon (gMoon = 1.62 m/s2)? The period at the Moon's surface, T = Units in s 2. The same pendulum is placed at the surface of an unknown planet X. What is the free fall acceleration at the surface of this planet if the pendulum has a period of 1.17...
What is the acceleration due to gravity on a planet where a 1.5 m long pendulum oscillates with the same period as a 0.8 kg mass vibrates on an 80 N/m spring?
Calculus question please help <3 . (ignore the working) 4. The period of a pendulum is given by T = 2 π l-where l is the length of the pendulum and g is the acceleration due to gravity. Suppose I = 5 feet feet with a maximum error of 0.01 feet .01 feet and T = 2 seconds with a maximum error of 0. 05 seconds Use differentials to estimate the maximum error of g Hint: solve for g first....
