Answer:
As the roller coaster goes higher, more potential energy is increased in the roller coaster. Caused by gravity and the roller coaster's position, the potential energy is stored in the roller coaster. For example, this ball is at the top of a hill, where potential energy is at it's highest. Potential energy can be calculated by Potential Energy=Mass X Acceleration X Height.
Explanation:
The factor that impact the amount of potential and kinetic energy should be explained below.
Factor impact the amount of energy:Since the roller coaster should be high which there should be more potential energy and the same should be increased.
Due to the gravity and the position of the roller coaster the potential energy should be stored in the rolar coaster.
Just like when the ball is in the top of the hill when there is high potential energy so in this way it should be impacted.

Hardin electronic corporation is designing a new cell phone, they need a solid material that will insulate the phone and product their users from electric shock. Which material would best fit the needs of Hardin engineers A. A non-metal B. A metalloid C. A metal D. A semiconductor
Answer:
A
Explanation:
The material that would best suit Hardin electronic corporation's need would be a non-metal.
Non-metals are naturally occurring substances or materials that lack the properties of metals. In other words, non-metals are poor conductors of heat and electricity, unlike metals.
Solid non-metals are, therefore, used as insulators in the design of materials. Hence, the best material for Hardin electronic corporation to use that will insulate the phone and protect their users from electric shock would be a non-metal.

A 0.56 kg model rocket produces 53 newtons of upward thrust as it shoots upward off the launch pad. With what acceleration meters per second-squared does the rocket launch?
resultant force = thrust – weight
acceleration = resultant force (newtons, N) divided by mass (kilograms, kg).
Acceleration = resultant force divided by mass
53N/0.56
=94.64 approximately 95
= 95m/s^2
This means that, every second, the speed of the rocket increases by 95m/s2
the S.I unit of Acceleration is meter per second square.
The acceleration in meters per second squared that the rocket launch is 94.64m/s²
According to Newton's second law, the formula for calculating the force acting on a body is expressed as;
F = ma
F is the applied force
m is the mass of the rocket
a is the acceleration of the rocket
Given the following parameters
Mass = 0.56kg
Force = 53N
Substitute the given parameters into the formula as shown:
F = ma
a = F/m
a = 53/0.56
a = 94.64m/s²
Hence the acceleration in meters per second-squared that the rocket launch is 94.64m/s²

Which best illustrates projectile motion
A pictorial diagram of a person hopping sideways at 5 different positions. The start and end positions are on the ground. The correct option is D.
What is projectile motion?Projectile motion is the motion of an artifact thrown or projected into the air that is only affected by gravity's acceleration. The object is known as a projectile, and its path is known as its trajectory.
Any object that is cast, fired, flung, heaved, hurled, pitched, tossed, or thrown is considered a projectile.
Throwing a ball straight up, kicking a ball at an angle to the horizontal, or simply dropping things and letting them fall are all examples of projectile motion.
The pictorial diagram of a person hopping sideways in five different positions best illustrates projectile motion. The starting and ending points are on the ground.
Thus, the correct option is D.

The first three positions of the rocket are shown with equal spacing between them.A pictorial diagram with a person swimming and position shown in equal time intervals and equally spaced.A pictorial diagram of a person hopping sideways at 5 different positions. The start and end positions are on the ground."Heat engines and heat pumps are similar in that they both operate on the principle that heat flows naturally from a hot substance to a colder one and, in the process, can be made to do work. However, there is an importance difference between them."
Answer:
The answer is below
Explanation:
The difference between a heat engine and a heat pump is that a heat engine is a device that converts Thermal energy into Mechanical Energy while a heat pump is a system that extracts heat from a cold body and delivers it to a hot body.
A Heat Engine generates mechanical energy (work) from the temperature difference between two thermal reservoirs while a Heat pump extract heat from a low temperature reservoir and delivers the heat energy to a high temperature reservoir.

Once started, why can nuclear fission continue to occur on its own?
a) The thermal energy released can cause the products to join.
b) The neutron formed by the reaction can cause more nuclei to combine.
c) The thermal energy released can cause the products to split.
d) A neutron begins the reaction, and more neutrons are formed in it.
Answer:
C. The thermal energy released can cause the products to split.
Explanation:
Because this is fission its bleeding off the atom.
A neutron begins the reaction and more neutrons are formed in it ( D )
When a nuclear fission is started it will continue to occur on its own because Nuclear fission is a form of reaction that starts with the splitting of the neutron of an atom into smaller nuclei which will continue to split into much smaller nuclei infinitely ( i.e. Chain reaction )
Hence we can say that once a Nuclear fission is started it can continue to occur on its own because A neutron begins the reaction and more neutrons are formed in it ( i.e. chain reaction )

10.00
120.0 V
20.0 2.
www
30.02
The voltage drop across the 20 Ohm resistor is 40V.
To determine the answer, we need to know about the current flowing through the resistor.
What is the total resistance of the circuit?As the three resistors are connected in series, so the resultant resistance is
10 Ohmv+ 20 Ohm + 30 Ohm = 60 Ohm
What is the current flowing through the resistors?As these resistors are connected in series, so the amount of current flowing through each resistor is equal.According to Ohm's law, current = voltage/resistanceCurrent= 120/60 = 2 A
What is the voltage across the 20 Ohm resistor?According to Ohm's law, voltage across the 20 Ohm resistor
= current×resistance
= 2×20
= 40volt
Thus, we can conclude that the voltage across the 20 Ohm resistor is 40V.

Janet jumps horizontally off a high diving platform with a velocity of 2.76 m/s and lands in the water 2.3 s later. How high is the platform? The acceleration of gravity is 9.8 m/s. Answer in units of m.
How far from the base of the platform does she land? Answer and units of m.
Answer:
(a) Let the height of the platform is h meter,
=>By s = ut + 1/2gt^2
=>h = 0 + 1/2 x 9.8 x (2.3)^2
=>h = 25.92 m
(b) By R = [Ux] x t
=>R = 2.47 x 2.3
=>R = 5.68 m
Explanation:
Explanation:
From the exercise we know the initial horizontal velocity and the time that Janet takes to land in the water
a) Knowing the formula for free falling objects, we can calculate how high is the platform
At t=2.3m the position of Janet is y=0m
So, the platform is 26m tall
b) According to dynamics the displacement of an object can be analyze using the following formula:
So, Janet lands 6 m far from the base of the platform
