Effort force
Explanation:
When the potion of fulcrum and weight is changed, the mechanical advantage changes.Increasing the distance between the fulcrum and the effort, there is a proportion increase in effort required to lift a load.The ration of the distance from the fulcrum to the position of input and output application gives the mechanical advantage in levers when losses due to friction are not considered.

Answer:
7.15/2 = 3.575m
1.78cos(45.4) = 1.25m
radius = 3.575 + 1.25 = 4.825 m
mg of seat = 10 x 9.8 = 98 N
98/sin(45.4) = 137.64 N
Horizontal force = 137.64cos(45.4) = 96.64 N
Centripetal force = 96.64 N
96.64/10 = 9.6644 = ca
9.6644 x 4.825 = v^2 = 46.63, sq-root = v = 6.83 m/s
(10 + 28.3) x 9.8 = mg = 375.34 N
375.34/sin(45.4) = 527.14 N
Explanation:
Answer: time is the same
Explanation: the distance(H) is the same in each case .
we drop the balls , no drag force using basic kimnematics
y =gt*t/2 , yo=0 , vo=0 , y=H , so : t= sqrt(2H/g)
comment: if distance H starts to grow....we could begin to note a difference because of gravity g is smaller as we go up

Explanation:
The circuits in the house uses an alternating voltage, For example the United States uses 120V 60 Hz AC. The circuits in the house use electrical components that are large such as switches, Contactors and circuit breakers, distribution board, Gear switches, lampholders, etc.
The circuits on a microchip in a computer uses a direct current supply. The voltage requirement is usually low (between 5V and 12V). In addition, micro electronic components, such transistors, resistors, low resistance wires, capacitors (in microFarad) are used.
Typically, the Home circuit is an electrical circuit while the circuit on the computer microchip is an electronic circuit with low voltage and current requirement and low power consumption.
Answer:
The impulse is 90Ns.
Explanation:
Given that the formula for impulse is F×t, where F represents force and t is time (in seconds) :
Impulse = F × t
Impulse = 30 × 3 = 90Ns
