Answer:
A greater period.
Explanation:
The period of a simple pendulum is represented by the following formula:
Where:
- Length of the pendulum
- Gravity constant
Given that gravity constant in the Moon is less than on Earth, period shall be greater.
Answer:
58.8 Joules work must be done
Explanation:
Equations of motion related distance, velocity and acceleration:
v² - v₀² = 2 x acc x Δdistance
so acc = (0 - 28²)/ (2 x 0.8 m) = -490 m/s² (negative acceleration means deceleration)
Ave force F to decelerate mass 0.15 kg = m x a = 0.15 x 490 = 73.5 Newtons
Work done W = Force x distance = 73.5 N x 0.8 m = 58.8 Nm (i.e. Joules)

There are several starting ingredients that are required for starting the process of photosynthesis. The most important are sunlight, water, carbon dioxide and certain minerals. Sunlight helps in building up the optimum temperature that is required to start the process of photosynthesis. Water is an important raw material that helps to absorb the carbon dioxide from the air. It also directly influences the opening and closing of the stomata. Carbon dioxide on the other hand is one of the most important raw material that helps to make glucose via the process of photosynthesis.</span>
