Answer:

  bust

Explanation:

At the same speed, kinetic energy is proportional to mass. The more massive object (the large bust) will have more kinetic energy.

Answer:

Bust

Explanation:

the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. The same amount of work is done by the body when decelerating from its current speed to a state of rest.

Explanation:

A P E X

The best explanation that compass needle points in the direction it

does is that the north pole of one magnet attracts the south pole of another magnet. Hence, option C is correct.

Anything that creates a magnetic field is considered to be a magnet. The most noteworthy characteristic of a magnet—a force that drags on other magnetic elements like iron, steel, etc.—is caused by this invisible magnetic field, which also attracts or repulses other magnets.

A piece of equipment built from a substance that has been magnetized and produces a consistent magnetic field is called a permanent magnet. A typical illustration is a fridge magnet used to keep notes on the door of the refrigerator. The term "ferromagnetic" refers to substances that can be attracted and are also powerfully drawn to a magnet.

These comprise several naturally occurring minerals, some alloys including rare-earth metals, and the elements iron, nickel, and cobalt and their alloys.

It is the property of the magnet that opposite poles attract each other, while the same poles repel each other.

Answer:

V = 1280 [V]

Explanation:

To solve this problem we must use ohm's law which tells us that the voltage is equal to the product of the resistance by the current.

Therefore we have:

V = I*R

where:

V =  voltage [V] (Units of volts)

I = current = 4 [amp]

R = resistance = 320 [ohms]

V = 4*320

V = 1280 [V]

A cannonball is shot from the top of a 47.8 m high hill at a speed of 53.7 m/s. The height then is 61.81 m/s.

The motion of an object with constant acceleration is described by a set of equations known as kinematic equations. Integrals, derivatives, and rates of change must all be understood in order to solve kinematics equations.

Velocity is the rate and direction of an object's movement, whereas speed is the time rate at which an object is moving along a path. In other words, velocity is a vector, whereas speed is a scalar value.

The kinematic equation is:

v² = u² + 2gs (a = g)

Where u is the initial velocity, a is the acceleration, and v is the velocity after the time period t.

(53.7)² + 2 x 9.8 x 47.8 m

Therefore, the height is 61.81 m/s.

it’s 144.2 I have it in my notes from when I was in school!!!!

Answer:

See the explanation below.

Explanation:

This is because the vacuum chamber removes all the air contained and for this reason, there is no force that opposes the movement of the feather when falling. We must remember that the free fall equation of kinematics is not a function of the mass of an object.

[tex]v_{f} =v_{o} +g*t[/tex]

where:

Vf = final velocity [m/s]

Vo = initial velocity [m/s]

g = gravity acceleration [m/s²]

t = time [s]

As we can see the mass of the object is not included in the equation.

Answer:

t = 2.38 [s]

Explanation:

To solve this problem we must use the following equation of kinematics. We must clarify that both the acceleration and the initial velocity were taken as positive, since the velocity of the movement coincides with the direction of the acceleration.

[tex]x =x_{o} +v_{o} *t+(\frac{1}{2} )*a*t^{2}[/tex]

where:

x - Xo = distance = 47 [m]

Vo = initial velocity = 8 [m/s]

a = gravity acceleration = 9.81 [m/s²]

t = time [s]

Now replacing these values in the equation:

47 = 8*t + 0.5*9.81*t²

47 = 8t + 4.905t²

47 = 4.905*t(1.63 + t)

9.58 = t*(1.63 + t) solving this equation (cuadratic)

we found that t = 2.38 [s]

Explanation:

This question is incomplete because of the absence of the average velocity at which the supplies are travelling in air. The formula to be used here if the completed question is obtained is

Average velocity (in m/s) =  distance (m) ÷ time (s)

Since we are looking for the time, then time should be made the subject of the formula

Schizophrenia is a persistent, severe mental illness that has an impact on a person's relationships with others as well as their thinking, acting, and emotional expression. Despite not being as prevalent as other severe mental illnesses, schizophrenia can be the most persistent and incapacitating.

Schizophrenia patients frequently struggle to function well in relationships, the workplace, and academic settings. They can appear to have lost their sense of reality, feel afraid and withdraw. This chronic illness cannot be cured, but it can be managed with the right care.

The average speed of the swimmer is equal to 1 m/s.

The average speed can be defined as the total distance traveled by the object in a specific time interval. The average speed can be defined as a scalar quantity as it possesses only the magnitude and does not have any direction.

The average speed can be determined from the ratio of the total distance the object covers to the time taken to travel that distance.

The equation for average speed can be written as follows:

Average speed =  Total distance/Total time taken

Given, the distance covered by the swimmer = 50 m

The total time taken by the swimmer = 50 sec

The average speed of the train = 50/50 = 1 m/s

Therefore, the average speed of the swimmer is equal to 1 m/s.

Answer:

Create

Broken

Explanation:

Bond formation or creation requires the use of energy. Energy is used during bond formation between chemical species. The energy is required for the reaction to occur.

Answer:

a. 2 kg*m/s

b. [tex]p_{T_{f}} = 0.5v_{f} = 2 kg*m/s[/tex]

c. 4 m/s

Explanation:

a. The momentum of the system ([tex]p_{Ti}[/tex]) before the blob of clay strikes the cart is:

[tex] p_{Ti} = p_{b} + p_{c} [/tex]

Where:

[tex]p_{b}[/tex] is the momentum of the blob clay

[tex]p_{c}[/tex] is the momentum of the car      

[tex] p_{Ti} = m_{b}v_{b} + m_{c}v_{c} [/tex]

Since the car is initially at rest, [tex]v_{c}[/tex] = 0

[tex] p_{Ti} = 200 g*\frac{1 kg}{1000 g}*10 m/s + 0 = 2 kg*m/s [/tex]

b. The momentum of the system after they come together:

[tex]p_{T_{f}} = m_{b}v_{b} + m_{c}v_{c}[/tex]

Since they come together, [tex]v_{b}[/tex] =

[tex]p_{T_{f}} = v_{f}(m_{b} + m_{c}) = v_{f}(0.2 kg + 0.3 kg) = 0.5v_{f}[/tex]   (1)

Because we do not have the final speed we can not calculate the final momentum.

c. We can find the speed of the clay and car by conservation of the momentum:

[tex] p_{i} = p_{f} [/tex]

The initial momentum of the system was founded in part "a" (p = 2 kg*m/s), so we have:

[tex] 2 kg*m/s = m_{b}v_{b_{f}} + m_{c}v_{c_{f}} [/tex]

Again, when they come together, the final speed is the same:

[tex] 2 kg*m/s = v_{f}(m_{b} + m_{c}) [/tex]                

[tex] v_{f} = \frac{2 kg*m/s}{0.2 kg + 0.3 kg} = 4 m/s [/tex]

Now, since we found the final speed we can calculate the momentum of the system after they come together (equation 1):        

[tex] p_{T} = 0.5v_{f} = 0.5 kg*4m/s = 2 kg*m/s [/tex]
