a 6.00-kg ornament is held at rest by two light wires that form 30° angles with the vertical, as shown in the figure. an external force of magnitude f acts vertically downward on the ornament. the tension exerted by each of the two wires is denoted by t. a free-body diagram, showing the four forces that act on the box, is shown in the figure. if the magnitude of force f is 410 n, what is the magnitude of the tension t?
Answers
The equilibrium condition allows finding the result for the tension of the cable that supports the block is:
The tension is: T₁ = 270.66 N
Newton's second law gives a relationship between force, mass and the acceleration of bodies, when the acceleration is zero it is called the equilibrium condition.
A free-body diagram of the forces is shown in the attachment.
Let's write the equilibrium equation for the vertical axis.
2 [tex]T_1_y[/tex] - f - W = 0
2 [tex]T_1_y[/tex] = W + f
Let's use trigonometry to find the tension, as the angle indicates that it is relative to the vertical.
cos 30 = [tex]\frac{T_1_y}{T_1}[/tex]
[tex]T_1_y[/tex] = T1 cos 30
We substitute.
2T₁ cos 30 = W + f
T₁ = m g + f / 2 cos 30
T₁ = [tex]\frac{6 \ 9.8 + 410}{2 \ cos 30}[/tex]
T₁ = 270.66 N
In conclusion using the equilibrium condition we can find the result for the tension of the cable that supports en bloc is:
The tension is: 270.66 N

3. Explain what forces the Egyptians had to overcome when building the pyramids
Answers
Answer:
(Hope this helps can I pls have brainlist (crown)☺️)
Explanation:
But how did the Egyptians overcome the extreme friction of dragging such massive things through the sandy desert, some of which weighed more than 9,000 pounds? Researchers at the University of Amsterdam have come up with a very simple solution to the friction problem: they utilised water.
The pyramids were not built by slaves, contrary to common perception. Archaeologists discovered the ruins of a purpose-built town for the hundreds of labourers who constructed the renowned Giza pyramids about 4,500 years ago.
The Egyptians had to overcome the force of friction while dragging the big blocks of stone and the force of gravity while uplifting the large stone structure to a greater height when building the pyramids.
What is friction?Friction is a type of force that resists or prevents the relative motion of two physical objects when their surfaces come in contact.
The friction force prevents any two surfaces of objects from easily sliding over each other or slipping across one another. It depends upon the force applied to the object.
Thus, while constructing the pyramids, the Egyptians had to fight against the forces of gravity and friction as they lifted the massive stone edifice to a greater height.

which of the following is an example of the law of multiple proportions?
Answers
The answer option which is an example of the law of multiple proportions is: B) Two different compounds formed from carbon and oxygen have the following mass ratios: 1.33 g O: 1 g C and 2.66 g O: 1 g C.
The Law of Multiple Proportions is also referred to as Dalton's Law and it states that when two chemical elements combine to form more than one chemical compound, the masses (weights) of one chemical element that combine with a fixed mass (weight) of the other chemical element will always be in a ratio of small whole numbers.
According to the Law of Multiple Proportions, when two chemical elements combine to form two different chemical compound, the masses (weights) of one chemical element that combine with 1 gram of the other chemical element can be expressed as a ratio of small whole numbers.
For example, carbon and oxygen react to form either carbon monoxide and carbon dioxide.
Carbon monoxide (CO):
12 grams of C = 16 grams of O.
1 gram of C = 1.33 gram of O.
Carbon dioxide ([tex]CO_2[/tex]):
12 gram of C = 32 grams of O.
1 gram of C = 2.66 gram of O.
Ratio of oxygen (O) = 16:32 = 1:2 (Law of Multiple Proportions).

A ball is thrown upward with an initial velocity of 22.0 m/s. If
the gravitational acceleration is –9.81 meters per second
squared, what is the maximum height the ball will reach?
Select one:
2.24 m.
24.7 m.
4.48 m.
49.4 m.
Answers
The maximum height reached by the ball during the upward motion is 24.7 m.
The given parameters;
initial velocity of the ball, u = 22 m/sThe maximum height reached by the ball is determined using the third kinematic equation as shown below;
v² = u² - 2gh
where;
v is the final velocity of the ball at the maximum height = 0h is the maximum height attained by the ball0 = u² - 2gh
2gh = u²
[tex]h = \frac{u^2}{2g} \\\\h = \frac{22^2}{2(9.8)} \\\\h = 24.7 \ m[/tex]
Thus, the maximum height reached by the ball during the upward motion is 24.7 m.
