OC, The Tariff of Abominations caused conflicts between the North and the South regarding their sectional interests.

Explanation:

The Tariff of Abominations did cause conflicts because it widened income inequality since it favored the rich upper class while burdening the lower class. The South was the lower class, and the North was more of the upper class.

The density of a glass is 2.5 g/cm3. if the glass breaks, what is the density of the smaller pieces

sp2606 [1]

Answer:

See the explanation below.

Explanation:

Density will remain the same since density is the relationship between mass and volume. As we can see in the equation below.

$Ro=m/V$

where:

Ro = density = 2.5 [g/cm³]

m = mass [g]

V = volume [cm³]

In such a way that when the glass is broken the small fragments retain the same density ratio. That is, each fragment has a small mass and a small volume. That's why the density remains the same.

It is easier to drive In sharp nails in a piece of wood than the blunt ones why?

murzikaleks [220]

The sharp nail has a less surface area in comparison to a blunt nail and pressure is inversely proportional to area so it is easier to Hamer a sharp nail into a wood rather than having a blunt nail in wood

Weight of a body is 100N, it's weight on the moon is

user100 [1]

We know

$\\ \tt\hookrightarrow W_e=6W_m$

m=moon
e=earth

$\\ \tt\hookrightarrow 100=6W_m$

$\\ \tt\hookrightarrow W_m=100/6$

$\\ \tt\hookrightarrow W_m=16.6N$

if the separation between two masses is doubled, does the gravitational force between them increase or decrease? By what factor?

docker41 [41]

Answer:

increase by a factor of 4.

Explanation:

If the separation distance between two objects is doubled (increased by a factor of 2), then the force of gravitational attraction is decreased by a factor of 4 (2 raised to the second power).

Why is 30% recommended as the minimum Michelson contrast?

forsale [732]

Answer:

Explained

Explanation:

Michelson contrast is used for patterns where the distribution of bright and dark segments is nearly equal.

It is given by:

$m= \frac{I_{max}-I{min}}{I_{max}+I{min} }$

where I_max = maximum illumination and I_min = minimum illumination

we know that

typically, I_min = 54% of I_max (general standard)

or I_min = 0.54 I_max

putting this value in above equation to get m

this approximately corresponds to m = 0.3 or 30%

hence, 30% recommended as the minimum Michelson contrast
