Answer:

1.1 x 10⁵m/s²

Explanation:

Given parameters:

Velocity  = 452m/s

distance  = 0.93m

Unknown:

Acceleration of the bullet  = ?

Solution:

To solve this problem, we use one of the kinematics equation which is given below:

           V² = U²  + 2aS

V is the final velocity

U is the initial velocity  = 0m/s

a is the unknown acceleration

S is the distance traveled  

 So;

          452²   = 0²  + (2 x a x 0.93)

          204304  = 1.86a

               a  = 1.1 x 10⁵m/s²

Answer:

A. The particle model, because only high-energy frequencies of light  can remove electrons .

Explanation:

Each photon of blue light has higher energy than each photon of red light has  . So when each photon strikes each electron , it gets ejected . But the photon of red light has not sufficient energy to eject electron . Once the photon of red light strikes the electron , the energy is wasted off . Energy of photon can not be accumulated . Thus photon behaves like particle .

Explanation:

Electric field, an electric property associated with each point in space when charge is present in any form. The magnitude and direction of the electric field are expressed by the value of E, called electric field strength or electric field intensity or simply the electric field.

Magnetic field are a region around a magnetic material or a moving electric charge within which the force of magnetism acts. Magnetic fields are produced by moving electric charges. Everything is made up of atoms, and each atom has a nucleus made of neutrons and protons with electrons that orbit around the nucleus. Since the orbiting electrons are tiny moving charges, a small magnetic field is created around each atom.

Similarities between magnetic fields and electric fields: Magnetic fields are associated with two magnetic poles, north and south, although they are also produced by charges (but moving charges). Like pole repel unlike poles attract. Electric field points in the direction of the force experienced by a positive charge.

Explanation:

I got it right on Acellus, rounded to 33300 sigfigs

When 0.0135 kg of steam at 100°C is cooled, turns it into water at 50.0°C. Then 33,342.45 J of heat has been removed.

Latent heat is the heat absorbed or released by a substance during a change in its physical state without a corresponding change in temperature. This means that the heat energy is being used to break or form intermolecular bonds between the particles in the substance, rather than raising or lowering the temperature. Examples of processes that involve latent heat include melting, freezing, vaporization, and condensation. The amount of heat required or released during these phase transitions is dependent on the substance and the amount of material undergoing the change.

Here in the question,

To solve this problem, we need to use the formula for the heat required to change the phase of a substance, which is given by:

Q = m * L

where Q is the heat required, m is the mass of the substance, and L is the specific latent heat of the substance.

In this case, we need to find the heat required to change 0.0135 kg of steam at 100°C to water at 100°C, and then cool it down to 50°C.

First, we need to find the heat required to change the phase of the steam to water at 100°C. Using the table given, we can see that the specific latent heat of vaporization for water is 2.26 × 10^6 J/kg. So the heat required to change 0.0135 kg of steam to water at 100°C is:

Q1 = m * L = 0.0135 kg * 2.26 × 10^6 J/kg = 30,510 J

Next, we need to find the heat required to cool the water from 100°C to 50°C. Using the specific heat capacity of water, which is 4186 J/(kg°C), we can calculate the heat required as:

Q2 = m * c * ΔT = 0.0135 kg * 4186 J/(kg°C) * (100°C - 50°C) = 2832.45 J

The total heat removed is the sum of the heat required to change the phase of the steam and the heat required to cool the water:

Q = Q1 + Q2 = 30,510 J + 2832.45 J = 33,342.45 J =33.34245 kJ.

Therefore, 33,342.45 J of heat has been removed.

Answer:

Approximately [tex]2.1\; \rm km[/tex], assuming that [tex]g = -9.8\; \rm m \cdot s^{-2}[/tex].

Explanation:

Let [tex]t[/tex] denote the time required for the package to reach the ground. Let [tex]h(\text{initial})[/tex] and [tex]h(\text{final})[/tex] denote the initial and final height of this package.

[tex]\displaystyle h(\text{final}) = \frac{1}{2}\, g\, t^2 + h(\text{initial})[/tex].

For this package:

Solve for [tex]t[/tex], the time required for the package to reach the ground after being released.

[tex]\displaystyle t^{2} = \frac{2\, (h(\text{final}) - h(\text{initial}))}{g}[/tex].

[tex]\begin{aligned} t &= \sqrt{\frac{2\, (h(\text{final}) - h(\text{initial}))}{g} \\ &\approx \sqrt{\frac{2\times (0\; \rm m - 2500\; \rm m)}{(-9.8\; \rm m \cdot s^{-2})}} \approx 22.588\; \rm s\end{aligned}[/tex].

Assume that the air resistance on this package is negligible. The horizontal ("forward") velocity of this package would be constant (supposedly at [tex]95\; \rm m \cdot s^{-1}[/tex].) From calculations above, the package would travel forward at that speed for about [tex]22.588\; \rm s[/tex]. That corresponds to approximately:[tex]95\; \rm m \cdot s^{-1} \times 22.588\; \rm s \approx 2.1 \times 10^{3}\; \rm m = 2.1\; \rm km[/tex].

Hence, the package would land approximately [tex]2.1\; \rm km[/tex] in front of where the plane released the package.

If you add 2 miles from west then 2 miles east then it would 4 miles all together.

Answer:

If there is a system of magnets being held in place, there is potential energy. When you let go, the potential energy converts to kinetic energy and the magnets move. Putting the system of magnets close together which creates an opposing force.

Explanation:

Magnets cause objects to have kinetic energy by the magnetic force present in the magnet.

Magnets is a material which has a strong magnetic field which attracts ferromagnetic substances such as nickle, iron etc.

When a ferromagnetic objects put near the magnet, the magnet attracts the object and causes the movement towards its direction.

Therefore, magnets cause objects to have kinetic energy by the magnetic force present in the magnet.

Answer:

It is not correct.

The correct conversion is:

1030 KJ = 246.18 KCal.

Explanation:

To know if 1030 KJ is equivalent to 245 KCal, we shall convert 1030 kJ to kcal. This can be obtained as follow:

4.184 KJ = 1 KCal

Therefore,

1030 KJ = 1030 KJ × 1 KCal / 4.184 KJ

1030 KJ = 246.18 KCal.

Thus, 1030 KJ is equivalent to 246.18 KCal.

From the above calculation, we can see that:

1030 KJ ≠ 245 KCal

Rather,

1030 KJ = 246.18 KCal.

Answer:

The work done on the system can be accounted for by;

Both [tex]E_g[/tex] and [tex]E_{int}[/tex]

Explanation:

The speed of the crate = Constant

Therefore, the acceleration of the crate = 0 m/s²

The net force applied to the crate, [tex]F_{NET}[/tex] = 0

Therefore, the force of with which the crate is pulled = The force resisting the upward motion of the crate

However, we have;

The force resisting the upward motion of the crate = The weight of the crate + The frictional resistance of the ramp due to the surface contact between the ramp and the crate

The work done on the system = The energy to balance the resisting force = The weight of the crate × The height the crate is raised + The heat generated as internal energy to the system

The weight of the crate × The height the crate is raised = Gravitational Potential Energy = [tex]E_g[/tex]

The heat generated as internal energy to the system = [tex]E_{int}[/tex]

Therefore;

The work done on the system = [tex]E_g[/tex] + [tex]E_{int}[/tex].

Solution :

Using the Gauss law, the electric field intensity of a sphere is given by :

[tex]$E. 4 \pi r^2 = \frac{Q_{enc}}{\epsilon_0}$[/tex]

[tex]$E = \frac{Q_{enc}}{4 \pi r^2 \epsilon_0}$[/tex]

Now the enclosed charge inside the sphere (r<a) is

[tex]$Q_{enc}= \rho V$[/tex]

[tex]$Q_{enc}= \rho \left( \frac{4}{3} \pi r^3 \right)$[/tex]

Hence, the electric field intensity becomes as follows :

[tex]$E= \frac{\rho \left(\frac{4}{3} \pi r^3\right)}{4 \pi \epsilon_0 r^2}$[/tex]

[tex]$E =\frac{\rho r}{3 \epsilon_0}$[/tex]

Thus, the electric field inside the sphere is given by :

[tex]$\vec {E} = \frac{\rho \vec{r}}{3 \epsilon_0}$[/tex]
