Answer:
The answer to the question is
Suki is 1.12 m close to the end of the steel beam before the beam begins to tip
Explanation:
To solve the question we list out the known variables first
Length of steel beam, L = 7.00 m
Weight of steal beam W = 326 N
Distance between supports = 3.00 m
Weight of Suki = 555 N
By moments theory, the sum of moments about a point = 0
and assuming the steal beam is uniform, the weight of the beam will act at the center of the beam
As described the supports are 2.00 m from each end of the beam thus
taking moments about one of the support with Suki between the end of the beam and the support we have
Distance from center of beam to support = 1.5 m
Distance of Suki to the nearest support = x m
therefore 555 × x + 326 × 1.5 = 0
or x = -0.881 m on the other side of the support
Therefore Suki is (2 - 0.881) m or 1.12 m close to the end before the beam begins to tip
Answer:
Assume that the sack was initially close to the sea level. Its weight will increase even though its mass stays the same.
Explanation:
The weight of an object typically refers to the size of the planet's gravitational attraction (a force) on this object. That's not the same as the mass of the object. The weight of an object at a position depends on the size of the gravitational field there; on the other hand, the mass of the object is supposed to be same regardless of the location- as long as the object stays intact.
Let 
denote the strength of the gravitational field at a certain point. If the mass of an object is 
, its weight at that point will be 
.
Indeed, 
on many places of the earth. However, this value is accurate only near the sea level. The equation for universal gravitation is a more general way for finding the strength of the gravitational field at an arbitrary height. Let 
denote the constant of universal gravitation, and let 
denote the mass of the earth. At a distance 
from the center of the earth (where
.
The elevation of many places in Bhutan are significantly higher than that of many places in India. Therefore, a sack of potato in Bhutan will likely be further away from the center of the earth (larger ) compared to a sack of potato in India.
Note, that in the approximation, the value of is (approximately, because the earth isn't perfectly spherical) inversely proportional to the distance from the center of the planet. The gravitational field strength
On the other hand, the weight of an object of fixed mass is proportional to the gravitational field strength. Therefore, the same bag of potatoes will have a smaller weight at most places in Bhutan compared to most places in India.

Answer:
A. predation.
Explanation:
Predation is a type of ecological interaction in which one organism which is known as predator feeds upon another organism thereby killing it. The organism which is killed by predator is known as prey. In such interaction one organism is benefited while another one is harmed.
Brown bears of Alaska feed upon salmon. In order to so they have developed many ways which include waiting at the bottom of falls from where salmons pass by or standing at the bottom of the falls.
Answer:
The molar mass of the organic solid is 120.16 g/mol.
The molecular formula of an organic solid is 
Explanation:
Let the molecular mass of an organic solid be 
where,
=Elevation in boiling point = 
Mass of organic solid= 0.561 g
Mass of diphenyl = 24.9 g = 0.0249 kg (1 kg = 1000 g)
= boiling point constant = 8.00 °C/m
m = molality
Now put all the given values in this formula, we get
Percentage of carbon in an organic solid = 40.0%
x = 4.0
Percentage of hydrogen in an organic solid = 6.7%
y = 8.0
Percentage of hydrogen in an organic solid = 6.7%
y = 4.0
The molecular formula of an organic solid is
