Which type of energy refers to the sum of potential and kinetic energies in the particles of a substance?Omotion Ostored O internal O heat

What happens to the pressure in all parts of a confined fluid if the pressure in one part is increased? The pressure in the other parts remains the same.The pressure everywhere increases by different amounts depending on the area of each part.The pressure everywhere increases by the same amount.The pressure everywhere decreases to conserve total pressure.

A ship is traveling at 154 m/s and accelerates at a rate of 1.80 m/s^2 for 1 minute. What will its speed be after that minute? Calculate the answer in both meters per second and kilometers per hour.

The volume control on a stereo is designed so that three clicks of the dial increase the output by 10 dB. How many clicks are required to increase the power output of the loudspeakers by a factor of 100?

A screen is placed 60.0 cm from a single slit, which is illuminated with light of wavelength 690 nm. If the distance between the first and third minima in the diffraction pattern is 3.10 mm, what is the width of the slit?

producers

decomposers

heterotrophs

Answer:

Explanation:

Decomposers is the correct answer

**Answer:**

Decomposers is the right answer

**Explanation:**

Maggots are decomposers because they eat the dead bodys for energy

Answer:

a.) Speed V = 29.3 m/s

b.) K.E = 1931.6 J

Explanation: Please find the attached files for the solution

The wheel's speed at the bottom of the hill can be found through the conservation of energy equation considering both translational and **rotational kinetic energy, **while the total kinetic energy at the bottom of the hill is a sum of translational and rotational kinetic energy.

These two questions address the physics concepts of conservation of energy, kinetic energy, and rotational motion. To answer the first question, (a) How fast is the wheel moving when it reaches the bottom of the hill if it rolled without slipping all the way down?, we need to consider the potential energy the wheel has at the top of the hill is completely converted into kinetic energy at the bottom. This includes both translational and rotational kinetic energy. Solving for the final velocity, vf, which would be the speed of the wheel, we get **vf = sqrt((2*g*h)/(1+I/(m*r^2))), **where g is the acceleration due to gravity, h is the height of the hill, I is the moment of inertia of the wheel, m is the mass of the wheel, and r is the radius of the wheel.

For the second question, (b) How much total kinetic energy does it have when it reaches bottom of the hill?, we use the formula for total kinetic energy at the bottom of the hill,** K= 0.5*m*v^2+0.5*I*(v/r)^2. **Substituting the value of v found in the first part we find the kinetic energy which we can use the formula provided in the reference information.

The **error **in her thinking is that **oxygen **has has **six electrons **and a **negative charge** is acquired by **nitrogen **when it gains **two electrons**.

Oxygen is a member of** group 16.** The elements in group 16 has six valence electrons. This means that they need an extra **two electrons** to complete their **octet**.

If an atom gains two electrons, it will have a charge of** -2 **and not **+2**, a positive charge means that the atom **lost electrons**. **Nonmetals **like **oxygen **do not loose electrons rather they **gain electrons**.

A .all of the above

B. 85% - 95% of your max heart rate

C. 20%-30% of your max heart rate

D. 50%-85% of your max heart rate

**Answer:**

B

**Explanation:**

A normal heart rate is from 85-95% the other heart rate is not normal because your heart is beating more than normal

**Answer:**

av=0.333m/s, U=3.3466J

b.

**Explanation:**

**a. **let be the mass of block A, and be the mass of block B. The initial velocity of A,

-The initial momentum =Final momentum since there's no external net forces.

Relative velocity before and after collision have the same magnitude but opposite direction (for elastic collisions):

-Applying the conservation of momentum. The blocks have the same velocity after collision:

#Total Mechanical energy before and after the elastic collision is equal:

Hence, the maxumim energy stored is **U=3.3466J**, and the v**elocity=0.333m/s**

**b**. Taking the end collision:

From a above,

We plug these values in the equation:

**Answer:**

15 m/s

**Explanation:**

We know that where f = frequency & d = wavelength .

So here.

Wavelength = 5 m

Frequency = 3 s⁻¹

Hence Speed = 5 * 3 = 15 m/s
