A proton of mass m is at rest when it is suddenly struck head-on by an alpha particle (which consistsof 2 protons and 2 neutrons) moving at speed v. If the collision is perfectly elastic, what speed will the alpha particle have after the collision

Newton's laws of motion describe the behaviour of objects when they are at rest or in motion.

The 5 lbs bag of sugar is at rest in this situation, and you are exerting a 5 lbs upward force on it. The sugar bag will continue to be at rest unless an outside force acts upon it, in accordance with the first law of motion. It is being subjected to an external force that you are applying.

According to the second law of motion, theforce exerted on the bag of sugar will have a direct proportional effect on how fast it accelerates. The mass of the bag of sugar is 5 pounds, and the force you are exerting on it is 5 lbs. Because\(\textsf{$\frac{\textsf{5 lbs (force)}}{\textsf{ 5 lbs (mass)}}$ = 1 (unit of accleration)}\), the bag of sugar will accelerate by 1 (unit of acceleration).

The third law of motion states that there is an equal and opposite reaction to every action. In this case, the sugar bag pushes down on your hand with a 5 lb force when you push up on it with a 1 lb force. The force you are providing to the bag of sugar will have an equal and opposite reaction here.

Therefore, this scenario illustrates all three of Newton's laws of motion

----------------------------------------------------------------------------------------------------------

Yes, this is an example of Newton's Third Law of Motion. Newton's Third Law of Motion states that for every action, there is an equal and opposite reaction. In this example, when you push upwards on the 5 lb bag of sugar with a force of 5 lb, the bag of sugar also pushes downwards on you with a force of 5 lb.In other words, the action is you pushing upwards on the bag of sugar and the reaction is the bag of sugar pushing downwards on you with the same amount of force. So, this is an example of Newton's Third Law of Motion.

Answer:

Explanation:

CO2 is linear whereas NH3 has a trigonal pyramidal shape. NH3 is sp3 hybridized and the lone pairs on nitrogen repel other groups around nitrogen thus the bond angle becomes less than 109.5 (typically around 106.7).

CO2 is also sp hybridized and both O are equally pulling on both sides rendering the molecule to be non polar and linear with a bond angle of 180.

a. the landing ramp should be placed at 276.298 ft horizontally from the launch point.

(b) the angle of the landing ramp is 30°.

(a)

Launch speed = 55.0 mph * (1.467 ft/s)

= 80.685 ft/s

Horizontal distance = Launch speed * Time of flight

Vertical velocity = Launch speed * sin(30.0°)

Time to reach maximum height = Vertical velocity / g

Vertical distance = (1/2) *g * t²

and Time = √(2 * Vertical distance / g)

Total time of flight = 2 * Time to reach maximum height + Time for descent

Horizontal distance = Launch speed * Total time of flight

The Vertical velocity = 80.685 ft/s * sin(30.0°)

= 40.3425 ft/s

Time to reach maximum height = 40.3425 ft/s / 32.2 ft/s²

Time to reach maximum height  = 1.253 s

Time of descent = √(2 * 25.0 ft / 32.2 ft/s²)

Time of descent  = 0.913 s

Total time of flight = 2 * 1.253 s + 0.913 s

Total time of flight = 3.419 s

In conclusion, the horizontal distance = 80.685 ft/s * 3.419 s

horizontal distance = 276.298 ft

b.

Hendry and Cathy will each throw an object, and the time and location at which they will collide can be determined using the laws of motion. Hendry's item had an initial velocity of 26.5 m/s, whereas Cathy's object had an initial velocity of 45 m/s. Hendry's object's equation of motion is given by: s = u*t + 0.5*a*t*2, where s is the displacement, u*t* is the starting velocity, t* is the time, and a*t* is the acceleration brought on by gravity.

The acceleration caused by gravity is negative since the item is being flung upward. The item that Cathy threw has the following equation of motion: s = u * t - 0.5 * a * t2.where s is the distance travelled, u is the starting speed, t is the passage of time, and an is the acceleration brought on by gravity. The acceleration caused by gravity is negative since the item is being flung upward.

These equations allow us to determine the location and timing of the two items' collision. By figuring out the two equations for t, one may determine the moment when the objects will collide. By changing the value of t in either equation, one may determine the distance at which the objects will collide. Therefore, using the equations of motion, it is possible to determine the moment and distance at which the two objects will collide.

The potential energy gained is 4550 J.

The potential energy that a huge item has in relation to another massive object due to gravity is known as gravitational energy or gravitational potential energy. When two objects descend toward one another, potential energy associated with the gravitational field is released.

The potential difference is given as:

U = mgh

Where U is the gravitational energy, m is the mass, g is the acceleration due to gravity, and h is the height.

Now, we have

Leopard's mass, m = 65kg

The height of the tree, h = 7 m

Acceleration due to gravity, g = 10N/kg

Therefore,

U = mgh

U = 65 × 7 × 10

U = 65 × 70

U = 4550 J

Thus, the leopard will need 4550 J of gravitational potential energy to climb 7 meters.

Answer:

0.228 nm

Explanation:

Atomic mass number of copper = 64

but an atomic mass unit = 1.66 x 10^-27 kg

therefore, the mass of the copper atom m = 64 x 1.66 x 10^-27 kg = 1.06 x 10^-25 kg

The number of atoms in this mass n = ρ/m

where ρ is the density of copper = 8.96 x 10^3 kg/m^3

==> n = (8.96 x 10^3)/(1.06 x 10^-25) = 8.45 x 10^28 atoms/m^3

We know that the volume occupied by this amount of atoms n = \(a^{3}\)

where a is the lattice constant

equating, we have

8.45 x 10^28 = \(a^{3}\)

a = 4.389 x 10^9

we also know that

d =  1/a

where d is the smallest distance between the two copper atom.

d = 1/(4.389 x 10^9) = 2.28 x 10^-10 m

==> 0.228 nm

Answer:

The person standing in front of the wood stove feels warmer a lot quicker than the person standing the same distance from the fire pit because of the way heat is being transferred from the fire to the person.

In the wood stove, thermal energy from the burning wood is transferred to the surrounding air, which is then forced out of the stove by convection. This convection creates a steady flow of hot air that heats up the surrounding space, including the person standing in front of the stove. This is a very efficient method of heating because the hot air is forced to circulate and distribute the heat throughout the space.

In contrast, in the fire pit, the thermal energy from the burning wood is transferred primarily by radiation. This means that the heat from the fire travels through the air in straight lines until it comes into contact with an object, like the person standing in front of the fire pit. While radiation is an effective way of transferring heat, it is not as efficient as convection because it doesn't circulate the hot air throughout the space as efficiently.

Furthermore, the wood stove is enclosed and designed to contain the heat within the stove. This means that less heat is lost to the surrounding environment and more heat is directed towards the person in front of the stove. In contrast, the fire pit is open and exposed, which means that much of the heat is lost to the surrounding environment and less heat is directed towards the person standing in front of the fire pit.

Therefore, the wood stove is a more efficient and effective method of heating because it uses convection to circulate the hot air and contains the heat within the stove, resulting in a faster and more intense warming effect on the person standing in front of it.

The total displacement as it travels between Emily and Luisa if Emily passes a soccer ball 5 m directly across the field to Ara, who then kicks the ball 12.5 m directly down the field to Luisa, is 17.5 meters.

All locations in a body that are moved from one state to another are assigned displacement vectors. The difference between a trajectory point's final and starting positions is known as displacement (for instance, the center of mass of a moving object). The precise route taken to arrive at the destination is not important.

An object's position changes if it moves in relation to a reference frame, such as when a passenger moves to the back of an airplane or a lecturer moves to the right in relation to a whiteboard. Displacement describes this shift in location.

The displacement is the total distance from one place to another, so, when Emily passes a soccer ball 5 m directly to the era and then the total displacement is equal to the total distance traveled by the football.

The total distance traveled by the ball = 5 + 12.5 = 17.5 meters.

Current cannot flow uphill in any of the listed options: a light bulb, a battery, a flowing water conduit, or a resistor. Hence option E) is the correct answer.

Current cannot flow uphill in any of the listed options: a light bulb, a battery, a flowing water conduit, or a resistor. In an electrical circuit, current is the flow of electric charge carried by electrons. Current flows in a closed loop, typically from the positive terminal of a power source (such as a battery) through the circuit components and back to the negative terminal. A light bulb, battery, flowing water conduit, and resistor all have specific roles within a circuit, but none of them allow current to flow uphill. In a circuit, current always flows from a higher electric potential to a lower electric potential. This is known as the direction of conventional current flow. In the case of flowing water, water flows downhill due to gravity, following the path of least resistance. Similarly, in an electrical circuit, current flows along the path of least resistance, from higher voltage (electric potential) to lower voltage. Therefore, option E) is the correct answer current does not flow uphill in any of the mentioned options.

The acceleration due to gravity on the planet Fergie is 0.0123 m/s^2.

Explanation:

We want to find the acceleration due to gravity on the planet Fregie. Let it be g m/s^2.

Now, the acceleration due to gravity is defined through the following equation:

\(mg = GMm/R^2\)

where m is the mass of an object on the surface of the planet, M is the mass of the planet, R is the radius of the planet, and G is the universal Gravitational constant.

Subsituting values for M = 6.23*10^23, R = 5.79*10^7, G = 6.67*10^(-11), we get

g = 0.0123 m/s^2.

Thus the acceleration due to gravity on the planet Fergie is 0.0123 m/s^2.
