Here as we can see that weight on the right side of ruler given as D is applying torque about the fulcrum this is counter balanced by weight on left side given as A
now by torque balance we can say
now we will have
now here as per given setup we can see that
so here we will have
so the weight required to hold D will be more and correct answer will be
<em>The setup increases the amount of force required to lift the block and, therefore, decreases your mechanical advantage.</em>
Answer:
Explanation:
Lateral inversion is a phenomenon where the right seems to be on the left and left seems to be on the right.It occurs due to the direction is reflecting of a direct surface.An example of this is a mirror/window.A mirror is a better example to explain this! Hope this helps lemme know if u dont
The deceleration of the car is observed as 2 m/s^2.
<h3>What is deceleration?</h3>
The term deceleration has to do with the decrease of velocity with time.
Given that;
v = 65 km/h or 18 m/s
u = 126 km/h to or 35 m/s
t = 8.5 s
a = ?
v = u - at
18 - 35 = -8.5a
a = 18 - 35/-8.5
a = 2 m/s^2

Answer:
The magnitude of the average induced emf is 90V
Explanation:
Given;
area of the square coil, A = 0.4 m²
number of turns, N = 15 turns
magnitude of the magnetic field, B = 0.75 T
time of change of magnetic field, t = 0.05 s
The magnitude of the average induced emf is given by;
E = -NAB/t
E = -(15 x 0.4 x 0.75) / 0.05
E = -90 V
|E| = 90 V
Therefore, the magnitude of the average induced emf is 90V
