The mass of the piece of copper, to the nearest whole number is 121 grams.
Given the following data:
Specific heat capacity of copper = 0.385 J/g°CInitial temperature = 150.0°CFinal temperature = 225.0°CQuantity of heat = 3,500 JoulesTo calculate the mass of the piece of copper, to the nearest whole number:
Mathematically, quantity of heat is given by the formula;
[tex]Q = mc\theta[/tex]
Where:
Q represents the quantity of heat.m represents the mass of an object.c represents the specific heat capacity.[tex]\theta[/tex] represents the change in temperature.Making "m" the subject of formula, we have:
[tex]m = \frac{Q}{c\theta}[/tex]
Substituting the given parameters into the formula, we have;
[tex]m = \frac{3500}{0.385(225-150)}\\\\m = \frac{3500}{0.385 \times 75} \\\\m = \frac{3500}{28.875}[/tex]
Mass, m = 121.21 ≈ 121 grams

Explanation:
An extranet is a private network that uses internet access to share part of its business information or operations with customers, distributors, and so on. It grants access to customers, distributors, vendors, and so on to the network without granting them access to the entire organization's network. So data such as invoices, orders made by third parties can be done on the organization's network without giving them full access to the entire network with the help of an extranet.

The angle between the dock and the line connecting Michael and the ship is 48°, and the angle between the other dock and the line connecting Jacob and the ship is 37°. A triangle with points labeled Ship, Jacob, and Michael is shown. The length between Michael and Jacob is 20 miles. The angle between the ship, Michael, and Jacob is 48 degrees. The angle between the ship, Jacob, and Michael is 37 degrees. If the ship can travel to either dock, which dock would be closest? Explain your answer. Michael’s dock would be closer because the angle opposite is smaller. Jacob’s dock would be closer because the angle opposite is smaller. Michael’s dock would be closer because the docks are 20 miles apart. Jacob’s dock would be closer because the docks are 20 miles apart.

What are triangle inequalities?The triangle inequality theorem explains the connection between a triangle's three sides. This theorem states that for any triangle, the sum of the lengths of the first two sides is always greater than the length of the third side.
The vertices must be colinear, which means that the three sides form a line segment rather than a triangle if the length of one side equals the total of lengths of the other two sides. The triangle inequality is what we refer to here. Any triangle side must be shorter than the sum of the other two sides.
Therefore, the correct option is A.) Michael’s dock would be closed because the angle opposite is smaller.

a rock falls for 1.43 seconds. how far did it fall?
The Answer is 10.03 m
Explanation:
Given,
time =1.43 s
distance =?
acceleration= 9.81
Now by the formula
s=ut + 1/2 gt^2
s= 0× 1.43 +1/2 (9.81)×(1.43)^2
s= 10.03 m
therefore distance = 10.03 m
The rock fell approximately 10.02 meters in 1.43 seconds in a vacuum with an acceleration of [tex]\( 9.80 \, \text{m/s}^2 \)[/tex]
To find the distance the rock fell, we can use the formula for distance traveled by an object in free fall:
[tex]\rm \[ \text{Distance} = \text{initial velocity} \times \text{time} + \frac{1}{2} \times \text{acceleration} \times \text{time}^2 \][/tex]
Given that the rock is falling from rest, the initial velocity u is 0 m/s. The acceleration due to gravity g is [tex]\rm \( 9.80 \, \text{m/s}^2 \)[/tex], and the time the rock falls t is 1.43 seconds. Plugging these values into the formula:
[tex]\[ \text{Distance} = 0 \times 1.43 + \frac{1}{2} \times 9.80 \times (1.43)^2 \]\[ \text{Distance} = 0 + \frac{1}{2} \times 9.80 \times 2.0449 \]\[ \text{Distance} = 0 + 10.0191 \]\[ \text{Distance} = 10.02 \, \text{meters} \][/tex]
So, the rock fell approximately 10.02 meters in 1.43 seconds in a vacuum with an acceleration of [tex]\( 9.80 \, \text{m/s}^2 \)[/tex]. The correct answer is indeed 10.02 meters.

Explanation:
a 15.0 kg block is attached to a very light horizontal spring of force constant 575 n/m and is resting on a smooth horizontal table (figure 1). suddenly it is struck by a 3.00 kg stone traveling horizontally at 8.00 m/s to the right, whereupon the stone rebounds at 2.00 m/s horizontally to the left.
The instantaneous velocity of the 15 kg. mass just after collision can be found by the principle of linear momentum.
a) The speed of the 15 kg. just after collision is 2 m/s.
b) The type of collision is inelastic collision
c) The compression of the spring is approximately 0.323 m.
Reasons:
The given parameters are;
Mass of the block attached to the spring, m₁ = 15.0 kg
Force constant of the spring, K = 575 N/m
Mass of the stone that strikes the block, m₂ = 3.00 kg
Speed of the stone, v₂ = 8.00 m/s
Speed with which the stone rebounds, v₃ = 2.00 m/s
a) The total initial momentum = 3 kg. × 8 m/s = 24 kg·m/s
The final momentum, just after collision = 3 × (-2) kg·m/s + 15 kg ×v₁
By conservation of momentum, we have;
24 kg·m/s = 3 × (-2) kg·m/s + 15 kg ×v₁
[tex]v_1 = \dfrac{24 \, kg \cdot m/s + 6 \, kg \cdot m/s}{15 \, kg} = 2 \, m/s[/tex]
The speed of the 15 kg. just after collision, v₁ = 2 m/s.
b) A collision is elastic when the kinetic energy of the collision is conserved
The initial kinetic energy, K.E.₁ = 0.5 × 3 kg. ×(8 m/s)² = 96 J
The sum of the final kinetic energy are;
0.5 × 3 kg. × (2 m/s)² + 0.5 × 15 kg × (2 m/s)² = 36 J
The initial kinetic energy ≠ The final kinetic energy
Therefore, the collision is not elastic
(c) The kinetic energy given by the block = The elastic potential energy gained by the spring
Kinetic energy of the block, K.E. = 0.5 × 15 kg × (2 m/s)² = 30 J
Elastic energy gained by the block = 0.5 × K × x² = 0.5 × 575 N/m × x²
Therefore;
0.5 × 575 N/m × x² = 30 J
[tex]x^2 = \dfrac{30 \, J}{0.5 \times 575 \, N/m} = \dfrac{12}{115} \, m^2[/tex]
[tex]x = 2 \cdot \sqrt{\dfrac{3}{115} } \approx 0.323[/tex]
The compression of the spring, x ≈ 0.323 m.
