Answer:
less than
Explanation:
Given;
mass of the person, m = 100 kg
acceleration due to gravity, g = 9.8 m/s²
The reading on the scale is determined by applying Newton's second law of motion;
R = mg - ma
R = m(g-a)
at constant velocity, the acceleration is zero
a = 0
R = m(g-0)
R = mg
R = 100 x 9.8
R = 980 N
Thus, the scale reading is equal to the weight of the person but less than 1000 N
-- The two 8-ohm resistors in parallel are equivalent to
a single 4-ohm resistor.
-- The current in the circuit is
(voltage) / (resistance) = (9v) / (4ohms) = 2.25 Amperes
-- If another resistor is added in parallel, then no matter how large
or small it is, the current in the circuit increases.
(When another lane is added to a road, the traffic capacity of the
road increases.)
The circuit is now equivalent to a 12.5-ohm resistor in parallel
with 4-ohms. That's ...
(12.5 x 4) / (12.5 + 4) = 50/16.5 = 3.03 ohms .
-- The new current is (9v) / (3.03 ohms) = 2.97 Amperes
Answer:
3 class lever .
Explanation:
Third class lever: In the third class lever, the effort is located in between fulcrum and load. Here, effort arm is shorter than the load arm. It cannot lift the heavy load but increases the speed of doing work. ............. can you me as brainlist pls
Answer is in the photo. I can't attach it here, but I uploaded it to a file hosting. link below! Good Luck!
