The lever is a movable bar that pivots on a fulcrum attached to or positioned on or across a fixed point. The lever operates by applying forces at different distances from the fulcrum, or pivot.
A lever amplifies an input force to provide a greater output force, which is said to provide leverage. The ratio of the output force to the input force is the mechanical advantage of the lever.
The mechanical advantage of the lever is increased by moving the fulcrum closer to the load i.e., by shifting the fulcrum towards the right. Moving the fulcrum away from the load has mechanical disadvantage as the distance between the load and the fulcrum increases, the input force becomes greater than the output force.
Answer:
Probably because the Bernoulli effect (lift) is insufficient in thinner air to keep the plane aloft - increasing the angle of attack will increase the lift on the airplane
Answer:
26500 W/m²
Explanation:
Given that:
The diameter of the dish d = 1.2 m
Assuming the Solar power P capture by the dish = 1300 W
The surface area of the pot is calculated by using the formula:
where; the diameter = 25 cm
Area =
Area = 
Area = 0.049 m²
The intensity is calculated by using the formula
I = power/area
I = 1300/0.049
I = 26530.6 W/m²
I ≅ 26500 W/m²
' D ' is the only correct statement on the list.
Electromagnetic waves are capable of traveling through
many substances, and they're also capable of traveling
through vacuum. Mechanical waves can't travel in vacuum.
