Inertia is determined by the mass of the object. greater the mass an object has, greater will be its inertia. smaller the mass an object has, smaller will be its inertia. Greater mass enables an object to resist change in its state of motion or rest while on the other hand smaller mass object can be easily made to change its state of motion or rest.
c. controlling
b. manipulated
d. dependent
Answer:
The presence of minerals in a country can significantly impact its prosperity in various ways. Minerals, such as precious metals, rare earth elements, and energy resources like coal and oil, can play a pivotal role in a nation's economic development. First, mineral extraction and exportation can generate substantial revenue, contributing to the country's gross domestic product (GDP) and foreign exchange earnings. Additionally, the mining industry often creates job opportunities, fostering employment and income growth. However, the dependence on mineral resources can also lead to economic volatility and resource depletion if not managed sustainably. Moreover, the equitable distribution of wealth generated from mineral resources and effective governance are crucial factors in ensuring that the prosperity derived from these minerals benefits the entire population rather than a select few. Ultimately, the presence of minerals can be a double-edged sword, offering economic opportunities while demanding careful management to achieve lasting prosperity.
Explanation:
h2 would be very large?
2) Without using equations, explain why making h2 very small would cause d to be small, even though
h1 would be large
B) Derive an equation for d in terms of h1, h2, m, and physical constants as appropriate.
(A)
(1) The reason for making very small is due to smaller value of horizontal component of launch velocity.
(2) The reason for making very small is due to smaller value of time of flight.
(B) The distance (d) covered by the block is .
Given data:
The mass of block is, m.
The height of table from the top of slide is, .
The height of table at the end of slide is, .
The height of room is, H.
(A)
(1)
If the launch velocity of the block is v, then its horizontal component is very small, due to which adjusting the height to be very small will cause the d to be small.
(2)
The height is dependent on the time of flight, and since the time of flight taken by the block to get to the floor is very less, therefore the block will not get sufficient time to accomplish its horizontal motion. That is why making very small will cause d to be smaller.
(B)
The expression for the distance covered by the block is,
..............................(1)
Here, v is the launch speed of block and t is the time of flight.
The launch speed is,
And the time of flight is,
Substituting the values in equation (1) as,
Thus, the distance (d) covered by the block is .
Learn more about the time of flight here:
A1) The reason why making h₁ very small would cause d to be small is; Because the horizontal component of the launch velocity would be very small.
A2) The reason why making h₂very small would cause d to be small is;
Because the time of flight it will take the object to get to the floor would be very small and as a result, the object would not possess enough time to move horizontally before the vertical motion.
B) The equation for d in terms of h₁ and h₂ is;
d = 2√(h₁ × h₂)
A) 1) The reason why making h₁ very small would cause d to be small is because the horizontal component of the launch velocity would be very small.
A) 2) The reason why making h₂ very small would cause d to be small is because the time of flight it will take the object to get to the floor would be very small and as a result, the object would not possess enough time to move horizontally before the vertical motion.
B) Formula for Launch Velocity is;
V = √(2gh₁)
h₁ was used because the top of the slide from where the student released the block has a height of h₁.
Also, the time it takes to fall which is time of flight is given by the formula;
t = √(2h₂/g)
h₂ was used because the height of the table the object is on before falling is h₂.
Now, we know that d is distance from edge of the table and formula for distance with respect to speed and time is;
distance = speed × time
Thus;
d = √(2gh₁) × √(2h₂/g)
g will cancel out and this simplifies to give;
d = 2√(h₁ × h₂)

b. Use equilibrium conditions to determine the magnitude of F⃗ LonK.
c. Use equilibrium conditions to determine the angle θ that describes the direction of F⃗ LonK. Use positive values if the force is directed above the positive x-axis and negative values if it is directed below the positive x-axis.
d. Construct a force diagram for the knot.
Answer:
Part a)
Part b)
Magnitude of the force is given as
Part c)
As we know that Y component of the force is negative so here the force is directed below the X axis
Explanation:
Part a)
Adrienne apply the force of 20 N along +X direction and Jim apply force of 40 N at 53 degree above negative X axis
so we will have
now let say the force exerted by Luis is F such that sum of all forces must be zero
now we have
so we have
Part b)
Magnitude of the force is given as
Part c)
As we know that Y component of the force is negative so here the force is directed below the X axis
So here we have
