Which kind of energy is greater? Potential or kinetic energy?

Explanation:

The question has no set meaning. Suppose you take a rock to the top of a building. You put the rock over the edge of the building. You don't drop it yet. The potential energy is greatest for the rock under this condition. The kinetic energy is 0 because the rock is not moving.

Now you let the rock go. As it falls, it looses distance to the ground which means that the Potential energy is nearing 0. The Kinetic energy is picking up because the rock is moving faster.

At the bottom of the rock's journey just before it hits the ground, the KE is at a maximum and the PE is nearly 0.

Answer: it depends potential energy is the build up of kinetic energy like going to the top of a roller coaster. kintic is the use of the potential energy like going down the roller coaster so depends how much energy one another give :)

Hope this helps you out :)

A girl sits on a tire swing and is pushed in a circular motion by her father. Her tangential speed is 2.8 m/s and the girl travels in a circle with a diameter of 4.0 m. What is the girl's centripetal acceleration?

Explanation:

tangential speed of the girl is given as

diameter of the circle is given as

so here the radius of the circle is given as

now we know that centripetal acceleration of the object moving in circle is given as

R = D/2 = 4.0 / 2 = 2 m

a = V² / R = 2,8² / 2 = 7.84 / 2 = 3.92 m/s²

The quantity of charge Q in coulombs (C) that has passed through a point in a wire up to time t (measured in seconds) is given by Q(t) = t3− 2t2 + 4t + 1. [See this example. The unit of current is an ampere 1 A = 1 C/s.] (a) Find the current when t = 0.7 s.

current = 2.67 A

Explanation:

we have given,

Q(t) = t³− 2t² + 4t + 1

to find I at t = 0.7s

we know

so,

current at t= 0.7s

I = 2.67 A

hence, current comes out to be 2.67 A

Which of these help create radio waves? changing electric and magnetic fields applied at right angles

longitudinal waves traveling along the horizontal direction

compressions traveling along the vertical direction

transverse waves traveling at different speeds

The one that help create radio waves is :
Changing electric and magnetic fields applied at right angles

Radio waves are transverse wave, which means  that the oscillations occurring perpendicular to the direction of energy transfer

hope this helps

A. changing electric and magnetic fields applied at right angles

Explanation:

A gas has a pressure of 48atm in a 15.5L container. It was found that at 25∘C the gas occupied a volume of 25L and had a pressure of 22atm. What was the initial temperature in degrees Celsius?

130.165636364°C

Explanation:

P = Pressure

V = Volume

n = Number of moles

R = Gas constant = 0.082 L atm/mol K

From ideal gas law we have

The initial temperature is

Answer: 130 degrees Celsius

Explanation:

P1V1 / T1 = P2V2 / T2

Let the subscript 1 represent the initial 15.5L of gas and the subscript 2 represent the gas at the final volume of 25L. Rewrite the temperature in Kelvin by adding 273.

P1=48atm, V1=15.5L, P2=22atm, V2=25L, T2=298K, and T1 is unknown.

Substitute the known values into the combined gas law equation.

P1V1 / T1=P2V2 / T2 → (48atm)(15.5L) / T1 = (22atm)(25L) / 298K

Solve the equation for T1, simplify, and round to the nearest degree.

T1 = P1V1T2 / P2V2

T1 = (48atm)(15.5L)(298K)(22atm)(25L)

T1 = 403K

To get the temperature in Celsius, subtract 273.

T1 = 130∘C

How can we use scientific knowledge and reasoning to help guide us when making decisions?

Scientific knowledge is the use of proof and evidences when making decisions. The first step in problem solving is of course, identifying the problem. How could you solve the problem if there is no problem in the first place? When one gets to identify the problem, the next step is gathering of information to know more about the problem. One needs to get to know and examine the pros – the benefits – and con – the flaws – of the problem well. After doing all the needed data gathering and possibly, experimentation, when can start looking for the possible solutions of the problem.

What velocity must a 1210 kg car have in order to have the same momentum as a pickup truck of mass 2250 kg and a velocity of 25 m/s?

The velocity of the car must be 46.48 m/s.

Linear Momentum:

The linear momentum of a body is defined as the product of its mass and its velocity, given by

P = mv

According to the question, the momentum of the truck is :

Now, the momentum of the car and the truck must be same, that is:

So the velocity of the car is 46.48 m/s.

brainly.com/question/4126751?referrer=searchResults

Explanation:

Momentum = mass(m) × velocity (v)

momentum of car = momentum of truck

1210 × v = 2250 × 25

v = 46.5 m/s

At what angle should the player aim the ball if it is thrown from a height of 8.5 ftft with a speed of 28 ft/sft/s?

θ = 56.09°

Explanation:

Given that

h = 8.5 ft

speed ,u= 28 ft/s

We know that acceleration due to gravity g

g= 32.2 ft/s²

The maximum height h is given as

Now by putting the values

θ = 56.09°

Therefore the angle will be θ = 56.09°
