!!! HELP PLEASE !!!

A group of friends are going bowling. They discuss how ball weight and speed can change the amount of
kinetic energy transferred to the pins.
They can use a 6 pound, 10 pound or 12 pound ball.
They can roll the ball at 10 miles per hour (beginner), 14 miles per hour (intermediate) or 18 miles per hour (professional) speed.

A. Describe a strategy that they could use to transfer the greatest amount of kinetic energy to the pins.

B. Explain the relationship between kinetic energy and strategy that you chose in part A.

C. Draw a model that demonstrates the energy transfers that occurred in the system.

Answer:

Explanation:

Force = Mass*Acceleration

Remember this formula because its one of the most used formula in all of physics.

250N = 80kg*Acceleration

a = 3.125 m/s^2

There would definitely be friction because of the water, but since this says high school physics, you prolly can assume it to be negligible

Answer:

The law which describes the behavior of gases in the Sun is Gay-Lussac's Law

Explanation:

The states that the extremely high pressure of the gases in the Sun produces extremely high temperature;

Therefore, the relationship between the pressure, 'P', of the gas and the temperature, 'T', of the gas is a direct relationship, which can be expressed mathematically as follows;

P ∝ T

The law which best describes the behavior of gases in the Sun is Gay-Lussac's Law, which states that the pressure of a given volume of gas varies directly as the absolute temperature of the gas, as follows;

P = K·T

∴ P/T = K (Constant)

[tex]\therefore \dfrac{P_1}{T_1} = \dfrac{P_2}{T_2}[/tex]

B. 8 I believe that this is the answer

Answer:

Explanation:

Force of friction and air resistance  acts against the external force . Let it be f .

net force = external force - frictional force and air resistance

Putting the given values

200 = 500 - f

f = 500 - 200 = 300 N .

Hence force of friction = 300 N .

Answer:

1) Changing value

2) The velocity is decreasing for upward motion and increasing for downward motion due to gravitational force

Explanation:

1) A trajectory is the motion of an object which is being acted upon by specified forces. The flight path of an object in projectile motion is its trajectory

During the course of a trajectory, the vertical component of the velocity, [tex]v_y[/tex], is a changing value

2) The vertical component of the velocity first decreases, during the upward motion, according to the following equation;

[tex]v_y[/tex] = [tex]u_y[/tex] - g·t

Where;

[tex]v_y[/tex] = The vertical component of the velocity after a given time, t

[tex]u_y[/tex] = The initial vertical velocity

t = The time of motion of the trajectory

g = The acceleration due to gravity ≈ 9.8 m/s²

When the vertical velocity of the object decreases to zero, which is the point at which the object reaches the maximum height of its motion, the direction of the vertical motion of the object reverses, and object begins to accelerate and increase its velocity downwards according to the following equation;

[tex]v_y[/tex] = [tex]u_y[/tex] + g·t

Therefore, the velocity of the object is decreasing on its way up, and then increasing on its way down.

Period, being a time, is measured in units of time such as seconds, hours, days or years. The period of orbit for the Earth around the Sun is approximately 365 days; it takes 365 days for the Earth to complete a cycle

Fluorine is the sample which is shiny but does not conduct heat and electricity through it. The flow of electricity requires the flow of electrons or charged particles. Thus, the correct option is A.

A conductor is a substance, chemical element, or a material which allows electricity and heat to flow through it. In a conductor, the electrical charge carriers which are usually electrons or positive and negative ions, move easily from one atom to another atom when a particular amount of voltage is applied.

Fluorine is a shiny element however it does not conduct heat and electricity through it. It is the most electronegative atom and is very reactive in nature. It only gains electrons and does not lose them. And because of this property of fluorine, it restricts the movement of electrons through it and fails to conduct electricity.

Therefore, the correct option is A.

Answer:

the cost of running the bulbs is 11.25p

Explanation:

Given;

cost of running 1 kwh = 10 p

power of filament bulb, P = 60 W

power of the CFL bulb, P = 15 W

time of power consumption, t = 15 hours

Total Energy consumed;

E = (60W + 15W) x 15 hours

E = (75)(15)

E = 1125 Wh

E = 1.125 kWh

Cost of 1.125 kWh  =   1.125 x 10p

                               = 11.25p

Therefore, the cost of running the bulbs is 11.25p

Exploding planet or astroifd

Answer:

Volcanoes that form away from plate boundaries are created by hotspots. A hotspot is an area in the mantle that is believed to be somewhat hotter than the surrounding material. The rising magma from the hotspot can push its way through the crust and burst out at the surface, forming a volcano.

Explanation:

Volcanoes can form in subduction zones, which are regions where tectonic plates are interacting one and plate is sinking beneath the other.

A volcano is a hill or mountain in the shape of a cone that is erected around a fissure in the surface of the earth thru which heated gases, rock fragments, and lava are released. A conical mass grows around the conduit as the solid fragments gather there, becoming progressively larger until it reaches the size of a gigantic volcanic mountain.

A volcano is an aperture or vent through which magma, tephra (small rocks), or steam are released onto the the planet's surface. Days, weeks, or even years might pass between outbursts of volcanoes.

Answer:

Final velocity, V = 35.5m/s

Explanation:

Given the following data;

Initial velocity = 28m/s

Acceleration = 2.5m/s²

Time = 3 seconds

To find the final velocity, we would use the first equation of motion

V = U + at

Where;

V is the final velocity measured in m/s.

U is the initial velocity measured in m/s.

a is the acceleration measured in m/s².

t is the time measured in seconds.

Substituting into the equation, we have;

V = 28 + 2.5*3

V = 28 + 7.5

Final velocity, V = 35.5m/s

Answer:

0.0000076 grams

Explanation:

We're given the half life of Tritium to be 12.3 years. In order to find out the amount of substabce remaining:

Let's first find how many 'half lives' are in 250 years.

[tex]n = \frac{250}{12.3} = 20.325[/tex]

Now what is half life? It means the time taken for a given quantity of an element to lose half it's mass.

So in 12.3 years we can find that The amount of 250 g of Tritium will be 250/2 = 125 g. In 24.6 years we'll have 125/2 = 62.5 g

So now we can devise a formula:

[tex]m = \frac{original \: amount}{ {2}^{n} } [/tex]

Where m is the remaining amount and n is th number of half lives in the time given.

Using this formula we can calculate:

[tex]m = \frac{10}{ {2}^{20.325} } [/tex]

Doing this calculation we get:

[tex]m = 0.0000076 \: g[/tex]

As we can see a very small value remains.

The Principle Of Conservation Of Mechanical Energy

In the absence of friction, the total mechanical energy is conserved. That means that

Em=U+K is constant, being U the potential energy and K the kinetic energy.

At the top of the path (point Q), Joshua is at rest but his height is at a maximum. Thus his kinetic energy is zero.

At point P, Joshua is at the minimum level (potential energy zero) and his speed is at a maximum.

At point R, Joshua has some height and some speed which means he has both types of energy.
