Answer:
Kinetic energy.
The explanation never existed
During this experiment:
The fan should be switched off to prevent air resistanceThe stopwatch zero error should be noted and corrected
The angle of bob displacement should be small
<h3>
Simple pendulum</h3>
The simple pendulum a system that moves in an oscillatory motion. It consist of a suspended mass on a string with length placed on a fixed support.
The acceleration due to gravity can be measured using a simple pendulum. During this experiment:
- The fan should be switched off to prevent air resistance
- The stopwatch zero error should be noted and corrected
- The angle of bob displacement should be small

Answer:
Answer is 519.3 J
Explanation:
GPE = m x g x h
Object Height is equal to 7.2 x sin42 = 7.2 x 0.669 = 4.817m
GPE = 11 x 9.8 x 4.817 =519.3 J
Most probably m value (11kg) has been used as 7.2 mistakenly.
Answer:
Ionic bonds form when a nonmetal and a metal exchange electrons, while covalent bonds form when electrons are shared between two nonmetals. An ionic bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions
The gravitational acceleration on the board of the Deepsea Challenger when it is in the Mariana Trench, 11 km below the surface of the Pacific Ocean is very large due to the high pressure. That is option B
<h3>What is gravitational acceleration?</h3>
The gravitational acceleration is the acceleration of an object that is under free fall. The acceleration due to gravity is 9.81 m/s2. above the sea level.
One of the factors that affect gravitational acceleration is depth. This is because as the depth increases so will pressure increase.
Increase in pressure leads to increase in gravitational acceleration.
Therefore, the gravitational acceleration on the board of the Deepsea Challenger when it is in the Mariana Trench, 11 km below the surface of the Pacific Ocean is very large due to the high pressure.
