A 115 kg anvil is 85.0 m above the Coyote. How much gravitational
potential energy does it have?
Answers
Answer:
[tex]\boxed {\boxed {\sf 95,795 \ Joules}}[/tex]
Explanation:
Gravitational potential energy is found using the following formula.
[tex]E_p=m*g*h[/tex]
where m is the mass, g is the gravitational acceleration, and h is the height.
1. Define Variables
We know the anvil's mass is 115 kilograms and it's 85.0 meters above the coyote. Assuming this is on Earth, the acceleration due to gravity is 9.8 m/s²
[tex]m=115 \ kg \\h= 85.0 \ m \\g= 9.8 \ m.s^2[/tex]
2. Calculate Potential Energy
Substitute the values into the formula.
[tex]E_p=(115 \ kg)*(9.8 \ m/s^2)*(85.0 \ m)[/tex]
Multiply the first two numbers together.
[tex]E_p=1127 \ kg*m/s^2*(85.0 \ m)[/tex]
Multiply again.
[tex]E_p=95795 \ kg*m^2/s^2[/tex]
1 kilogram square meter per square second is equal to Joule. Therefore, our answer of 95795 kg*m²/s² is equal to 95795 J[tex]E_p=95795 \ J[/tex]
The anvil has 95,795 Joules of gravitational potential energy.

If I start with an 30 gram sample of Plutonium-244, how many grams would be left of Plutonium-244 after 1 half life
Answers
Answer:
15 g
Explanation:
Given,
Plutonium-244 = 30 g
We have to find the gram of Plutonium-244 left after 1 half-life.
We know that the half-life of a radioactive isotope is constant. The half-life of a Radioactive isotope does not depend on the initial amount of isotope.
Now,
After 1 half-life
Plutonium-244 left = [tex]\dfrac{30}{2}[/tex]
= 15 g
Hence, 15 g of the Plutonium-244 will be left after 1 half-life.

What quantities are needed to describe the position of a water fountain relative to where you are standing?
Answers
Answer:
D. the distance and direction to the water fountain
Explanation:
To describe the position of a water fountain relative to where one is standing, the distance and direction to the water fountain must be known.
This quantity is known as the displacement.
Displacement is a vector quantity with both magnitude and direction. To specify the magnitude of a displacement, we use the length of path and in this case the height or sometimes the distance. The direction attribute distinguishes distance from displacement The perfect quantity to solve this problem is the displacement and it specifies the distance of the path and the direction traveled.In a nuclear station if the temperature of the superheated water starts to decrease what should the engineer in charge of the reactor do?

Juan y Pedro transportan una caja que pesa 120,00 Lb sobre una tabla uniforme de 12 pies de largo y peso de 44,5 Lb. El peso de 120 Lb está a 4,9 pies de Pedro. ¿Cuál es el módulo de la fuerza en Lb que debe ejercer Pedro por el extremo derecho de la tabla horizontal para sostener este peso?
Answers
Answer:
F = 93.25 lb
Explanation:
To solve this problem let's use the rotational equilibrium condition
Σ τ = 0
let's fix a reference system located at the end of the table, the position of Juan and assume the counterclockwise turns as positive
F_jhon 0 - w l / 2 - W (l-4.9) + F l = 0
F = w l / 2 + W (l -4.9) / l
where w is the weight of the table and W the weight of the box
let's calculate
F = (44.5 12/2 + 120 (12- 4.9)) / 12
F = 93.25 lb

In a typical golf swing the club is in contact with the ball for about 0.0010 s. If the .045 kg ball experiences a force of 4000 N, what is the final velocity of the golf ball?
Answers
Answer:
v = 88.89 [m/s]
Explanation:
To solve this problem we must use the principle of conservation of momentum which tells us that the initial momentum of a body plus the momentum added to that body will be equal to the final momentum of the body.
We must make up the following equation:
[tex]F*t = m*v[/tex]
where:
F = force applied = 4000 [N]
t = time = 0.001 [s]
m = mass = 0.045 [kg]
v = velocity [m/s]
[tex]4000*0.001=0.045*v\\v=88.89[m/s][/tex]

What is included in the units of Velocity that make it different from speed?What is included in the units of Velocity that make it different from speed?
Answers
Answer:
Direction
Explanation:
Speed is a measure of the distance covered by a moving object relative to the time it takes. It is a scalar quantity and, hence, measured irrespective of the direction the object is moving.
Velocity, on the other hand, is the speed of a moving object in a particular direction. It is a vector quantity, meaning that the direction of the moving object is important.
Therefore, the difference in the unit of speed and velocity is direction. The direction must be included in the unit of velocity.

A 2.25kg solid sphere has a rotational inertia about its center
• of gravity of 1.52kg.m2. What is the radius of the sphere?
Answers
Answer:
r = 1.3m
Explanation:
The moment of inertia of a solid sphere can be expressed using the formula;
I = ⅖ mr²
Where;
I = moment (kgm²)
m = mass of the sphere (kg)
r = rotational radius of the sphere (m)
Based on the provided information in this question, I = 1.52 kgm², m = 2.25 kg, r = ?
1.52 = ⅖ × 2.25 × r²
1.52 = 0.4 × 2.25 × r²
1.52 = 0.9 × r²
1.52 = 0.9r²
r² = 1.52/0.9
r² = 1.688
r² = 1.69
r = √1.69
r = 1.3m

A cyclist travels 1850 m north and then 1200 m south. Find both the distance it has traveled and the magnitude of its displacement.
Answers
Answer:
The distance it has traveled is 3,050 m and the magnitude of its displacement is 650 m north.
Explanation:
Distance refers to the length between any two points in space, while displacement refers to the distance from a start position to an end position regardless of the path.
In other words, distance refers to how much space an object travels during its movement; is the quantity moved. It is also said to be the sum of the distances traveled. The distance traveled by a mobile is the length of its trajectory and it is a scalar quantity. In this case, the distance is calculated as:
1850 m + 1200 m= 3,050 m
Displacement refers to the distance and direction of the final position from the initial position of an object. The displacement effected is a vector quantity. The vector representing the displacement has its origin in the initial position, its end in the final position, and its module is the distance in a straight line between the initial and final positions. That is, when expressing the displacement it is done in terms of the magnitude with its respective unit of measurement and the direction because the displacement is a vector type quantity. Mathematically, the displacement (Δd) is calculated as:
Δd= df - di
where df is the final position and di is the initial position of the object.
In this case, the displacement is calculated as:
1850 m - 1200 m= 650 m
Since the distance to the north is greater, the direction of travel will be to the north.
The distance it has traveled is 3,050 m and the magnitude of its displacement is 650 m north.
A man walks 2.6 miles east, then turns and walks 6.7 miles north. What is his resultant
vector from start to finish?
Answers
Answer:
Yes cause he walks 6.7 miles
The displacement vector of the man is equal to 17.41 miles in the Northeast direction.
What is displacement?The displacement of an object can be defined as the shortest distance between two points. The displacement can be described as a vector quantity because contains both direction and magnitude. The displacement can be positive (+ve), negative, or zero and can change with time.
The distance is the total path traveled and is a scalar quantity as it has only magnitude, and no direction. The distance is always positive (+ve), it can never be equal to zero.
Given, a man moves 2.6 miles along AB in the East and then 6.7 miles North along BC.
The displacement (AC) of the man can be calculated by using Pythagoras' theorem:
AC² = AB² + BC²
AC² = (2.6)² + (6.7)²
AC² = 6.76 +44.89
AC = 17.41 miles
Therefore, the displacement vector of the man is 17.41 miles.

for most other materials?
Answers
Answer:
i) Hooke's Law works for some materials
ii) Hooke's Law only applies up to a certain force
iii) The force at which Hooke's Law stops working for springs is lower than for most materials
Explanation:
Hooke's Law of elasticity states that the deformation of an elastic material is proportional to the applied for small deformations
The law is applicable to elastic materials whose values of deformation or extension as well as the applied load or stress are expressible by a single real number
Hooke's Law is applicable when the force and the extension of the elastic material are proportional, at larger force, the elastic material is observed to expand more than as expected based on Hooke's Law
The nature of springs is such that its elastic limit is reached by a much lower force than for most materials. Therefore, Hooke's law stops working for springs at a lower force than for most materials.
