Answer:
I. 90%
II. 60 MW
Explanation:
From the question given above, the following data were obtained:
Power input = 600 MW
Power output = 540 MW
I. Determination of the efficiency.
Power input = 600 MW
Power output = 540 MW
Efficiency =?
Efficiency = output / input × 100
Efficiency = 540 / 600 × 100
Efficiency = 90%
II. Determination of the power wasted by the pump.
Power input = 600 MW
Power output = 540 MW
Power wasted =?
Power wasted = Power input – Power output
Power wasted = 600 – 540
Power wasted = 60 MW
When water waves meet, they can combine to form new waves. In constructive waves, a ________ amplitude wave is formed. In destructive waves, a wave with a __________ amplitude is formed. A) greater, smaller B) smaller, greater C) smaller, smaller D) greater, greater
Answer:
In constructive waves, a greater amplitude wave is formed. In destructive waves, a wave with a smaller amplitude is formed. (option A)
Explanation:
Interference is called the superposition or sum of two or more waves. Depending mainly on the wavelengths, amplitudes and the relative distance between them, there are two types of interference: constructive or destructive.
Constructive interference occurs when there are two waves of identical or similar frequency (both have motions equal to an even number of similar wavelengths) and overlap the peak of one with the peak of the other. These effects add together and make a wave of greater amplitude. All of this is possible because the waves were in the same phase in the beginning (in the same position).
Destructive interference occurs in the opposite case to constructive. When the crest of one wave overlaps the valley of the other, they cancel out since they are in different phases when they overlap (they were in different positions). That is, as in the case of constructive waves they were added, in the case of destructive waves they cancel out (subtract).
So, In constructive waves, a greater amplitude wave is formed. In destructive waves, a wave with a smaller amplitude is formed.

Se usa una bombona de He para inflar globos, de volumen 15L con una presión de 200 atm. Si los globos tienen un volumen de 1.5L y presión de 770mmHg. ¿Cuántos globos se pueden llenar?
Answer:
La cantidad de globos llenos es de aproximadamente 1.974 globos
Explanation:
Los parámetros dados son;
El gas utilizado para inflar el globo = Él
El volumen del gas He, V₁ = 15 L
La presión del gas He, P₁ = 200 atm = 20,265,000 Pa
El volumen de cada globo = 1,5 L
La presión del He dentro del globo, P₂ = 770 mmHg = 102,641 Pa
Sea 'V₂', que represente el volumen total que el gas ocupa en todos los globos, y 'x', que represente el número de globos;
Por lo tanto, tenemos;
1,5 · x = V₂
Según la ley de Boyle, tenemos;
P₁ · V₁ = P₂ · V₂
∴ V₂ = P₁ · V₁ / (P₂)
Al introducir los valores conocidos, obtenemos;
V₂ = 20,265,000 Pa × 15 L / (102,641 Pa) = 2,961.53548 L
1,5 L × x = V₂
∴ 1,5 L × x = 2,961,53548 L
x = 2,961.53548 L / (1.5 L) = 1,974.35699 redondeamos hacia abajo para obtener un número entero de globos de la siguiente manera;
El número de globos, x ≈ 1,974 globos.

in what way is Speed related to Kinetic Energy?
Answer:
Explanation:
In order to find kinetic energy, you need information about the velocity. Speed is the magnitude of the velocity.
Kinetic energy is 1/2mv^2
m being mass
v being velocity
The kinetic energy of an object is directly proportional to the speed of the object. If we double the speed of the object then the kinetic energy of the object will increase by a factor of four or four times.
What is Kinetic energy?Kinetic energy is the energy which is present in an object which has because of its motion. If we want to accelerate an object, then we must apply the force of some magnitude. Applying a force, requires us to do some work. After the work has been done, then the energy has been transferred to the object, and the object will be moving with a new constant speed.
Kinetic energy is directly proportional to the mass of the object and to the square of its speed or velocity:
K.E. = 1/2 m × v²
If the mass has the units of kilograms and the velocity of meters per second, then the kinetic energy has units of kilograms-meters squared per second squared.

3. A 6 kg block moving to the right at 4 m/s collides with and sticks to a stationary block of unknown mass. If the two blocks move off to the right at 3 m/s, what was the mass of the stationary block?
Answer: 2kg
Explanation:
This problem is a textbook conservation of momentum problem. The intial momentum is equal to the final momentum. For the initial state of each block, only the first one was moving. Then they both combine to move together.
Pi = Pf
with p = mv
(6kg)*(4m/s) = (6kg+xkg)(3m/s)
Let x equal the unknown mass of block 2
24 = 18 + 3x
6 = 3x
x = 2kg

Define potential energy (PE)
Answer:
Potential energy is the energy that exists by virtue of the relative positions (configurations) of the objects within a physical system.
This form of energy has the potential to change the state of other objects around it, for example, the configuration or motion.
Various forms of energy can be grouped as potential energy.
Each of these forms is associated with a particular kind of force acting in conjunction with some physical property of matter (such as mass, charge, elasticity, temperature etc).
For example, gravitational potential energy is associated with the gravitational force acting on object's mass; elastic potential energy with the elastic force (ultimately electromagnetic force) acting on the elasticity of a deformed object; electrical potential energy with the coulombic force; strong nuclear force or weak nuclear force acting on the electric charge on the object; chemical potential energy, with the chemical potential of a particular atomic or molecular configuration acting on the atomic/molecular structure of the chemical substance that constitutes the object; thermal potential energy with the electromagnetic force in conjunction with the temperature of the object.
For an example of gravitational potential energy, consider a book placed on top of a table.
To raise the book from the floor to the table, work must be done, and energy supplied. (If the book is lifted by a person then this is provided by the chemical energy obtained from that person's food and then stored in the chemicals of the body.) Assuming perfect efficiency (no energy losses), the energy supplied to lift the book is exactly the same as the increase in the book's gravitational potential energy.
The book's potential energy can be released by knocking it off the table.
As the book falls, its potential energy is converted to kinetic energy.
When the book hits the floor this kinetic energy is converted into heat and sound by the impact.
Explanation:
Answer:
potential energy is basically stored energy
