Ignition safety switch
The ignition safety switch, often known as the engine cut-off switch, is the most critical piece of equipment for preventing propeller strike injuries. The purpose of this device is to turn off the boat engine immediately so the propeller will be halted and an accident can be avoided.
Bread is considered to be a heterogeneous mixture. It is a heterogeneous mixture because all of the components that are used to make the bread are physically separate.
W = F x d/x = (m x Ag) x h, therefore, mass (2kg x 9.8) x 2.5m = 49J
Answer:
196J
Explanation:
Given parameters:
Mass of skateboard = 1kg
Height off the ground = 20m
Unknown:
Potential energy = ?
Solution:
The potential energy is the energy due to the position of a body above the ground.
It is mathematically expressed as:
Potential energy = mass x acceleration due gravity x height
Potential energy = 1 x 9.8 x 20 = 196J
The top of the trajectory is the point where it changes from rising to falling. At that exact instant, its vertical speed is zero.
