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

$W_aL_a = W_bL_b$

now we will have

$W_a = W_b\times \frac{L_b}{L_a}$

now here as per given setup we can see that

$L_b > L_a$

so here we will have

$W_a > W_b$

so the weight required to hold D will be more and correct answer will be

The setup increases the amount of force required to lift the block and, therefore, decreases your mechanical advantage.

Fill in the blank. When the northern hemisphere experiences autumn, the southern hemisphere experiences __________.

Helga [31]

Answer:

When the northern hemisphere experiences autumn, the southern hemisphere experiences spring

Explanation:

When the northern hemisphere experiences autumn, the southern hemisphere experiences spring

This is due to the equinoxes. An equinox is an event that occurs twice a year. During these seasons all areas of the Earth's surface experience an equal amount of daylight and darkness. The sun is on the equator line, so the day and night in both hemispheres have the same duration. At that time the part of the Earth closest to the Sun is the equator.

The shape of the Earth means that while the spring equinox is experienced in the northern hemisphere, the autumn equinox is entered in the southern hemisphere.

A baseball is thrown horizontally from a cliff at 30 m/s and lands 7 seconds after the baseball was thrown. Calculate the horizo

ASHA 777 [7]

Answer:

The horizontal and vertical distances are x = 210 m and y = -240.35 m, respectively.

Explanation:

Using the equation of the displacement in the x-direction, we have:

(let's recall we have a constant velocity in this direction)

$x=v_{ix}t$

Where:

v(ix) is the initil velocity in the x direction (v(ix) = 30 m/s)
t is the time (t = 7 s)

$x=30(7)$

$x=210\: m$

Now, we need to use the equation of the displacement in the y-direction to find the vertical distance. Here we have an acceleration (g)

$y=v_{iy}t-\frac{1}{2}gt^2$

Where:

v(iy) is the initial velocity at the y-direction. In this case, it will be 0
t is the time
g is the acceleration of gravity (g=9.81 m/s²)

Then, the vertical position at 7 s is:

$y=-\frac{1}{2}(9.81)(7)^2$

$y=-240.35\: m$

Therefore, the horizontal and vertical distances are x = 210 m and y = -240.35 m, respectively. The minus sign means the negative value in the y-direction.

I hope it helps you!
