What is the average velocity of atoms in 1.00 mol of neon (a monatomic gas) at 465 K? For m, use 0.0202 kg.
Answer: 757m/s
Explanation:
Given the following :
Mole of neon gas = 1.00 mol
Temperature = 465k
Mass = 0.0202kg
Using the ideal gas equation. For calculating the average kinetic energy molecule :
0.5(mv^2) = 3/2 nRt
Where ;
M = mass, V = volume. R = gas constant(8.31 jK-1 mol-1, t = temperature in Kelvin, n = number of moles
Plugging our values
0.5(0.0202 × v^2) = 3/2 (1 × 8.31 × 465)
0.0101 v^2 = 5796.225
v^2 = 5796.225 / 0.0101
v^2 = 573883.66
v = √573883.66
v = 757.55109m/s
v = 757m/s

if you crash your car how could you decrease the damage to you or the car using the concept of impulse
Explanation:
Crumple zones are sections in cars that are designed to crumple up when the car encounters a collision. Crumple zones minimize the effect of the force in an automobile collision in two ways. By crumpling, the car is less likely to rebound upon impact, thus minimizing the momentum change and the impulse.
If a (hypothetical) atom with 30 protons and 44 neutrons undergoes alpha decay:
how many protons will be left in the nucleus?
how many neutrons will be left in the nucleus?
Answer:
Protons = 28
Neutrons = 42
Explanation:
Alpha decay is one of radioactive decay in which the atomic nuclei can be illustrated by the emission or loss of helium particles of mass number 4 and proton number of 2
Because mass number is the sum of protons and neutrons, If a (hypothetical) atom with 30 protons and 44 neutrons undergoes alpha decay, 28 protons will be left in the nucleus and 42 neutrons will be left in the nucleus.

Write down the equation that links energy transferred, charge flow, and
potential difference.
Answer:
The description of the given scenario is described in the explanation segment below.
Explanation:
As a charge passes through some kind of potential gap, the electrical task is undertaken as well as energy will be transferred. The Potential difference seems to be an amount of work performed per unit charge and is denoted by "V" as well as a charge is denoted by "Q".The energy transferred could be determined by using the following equation or formula:
⇒ Energy transferred = charge × potential difference
The equation that links energy transferred, charge flow, and potential difference (voltage) is: [tex]E = qV[/tex]
In Science, when a potential difference (voltage) is applied on an object, it gains some potential energy, which is then converted to kinetic energy.
The kinetic energy possessed by the object is responsible for the movement of electrons from one point to another in an electric field.
Hence, the quantity of energy in an electric circuit is directly proportional to the charge and potential difference (voltage) applied on the object.
Mathematically, the energy transferred in an electric field is given by the formula:
[tex]E = qV[/tex]
Where:
E is the energy transferred.q is the charge.V is the potential difference.Read more: https://brainly.com/question/23153766
A mover uses a ramp to load a crate of nails onto a truck. The crate, which must be lifted 1.5 m from the street to the bed of the truck, is pushed along the length of the ramp. If the ramp is 4.5 m long and friction between the ramp and crate can be ignored, what is the mechanical advantage of the ramp?
Answer: M.A = 3
Explanation:
A ramp is an example of an inclined plain. Where the
Height H = 1.5 m
Length L = 4.5 m
Mechanical advantage of a machine is the ratio of the load to effort. While mechanical advantage M.A of an inclined plain is the ratio of the length of the plain to the height of the plain.
M.A = L/H
Substitute the values of L and H into the formula
M.A = 4.5/1.5 = 3
The mechanical advantage of the ramp is 3

Two waves with amplitudes of 52 units and 98 units come together. Their amplitude, which is measured at a specific point and time, is 46 units. What wave behavior explains this value? A. destructive interference B. constructive interference C. refraction D. diffraction E. partial transmission
Answer: A
destructive interference
Explanation: Interference involves coming together of two waves of the same type. E.g sound waves, water waves e.t.c
Whenever two waves of different amplitude interferes with one another and there is increase in amplitude, this is known as constructive interference.
But whenever there is decrease in amplitude as a result of interference of the two waves, this is known as destructive interference.
If Two waves with amplitudes of 52 units and 98 units come together. Their amplitude, which is measured at a specific point and time, is 46 units. The wave behavior that explains this value is destructive interference because of decrease in the units of amplitude.

Light travels approximately 982,080,000 ft/s, and one year has approximately 32,000,000 seconds. A light year is the distance light travels in one year.
Calculate the distance of one light year in feet.
Answer: 3.142656 × 10^16 feet
Explanation: Given that the
Speed = 982,080,000 ft/s, and
Time = 32,000,000 seconds
The formula for speed is:
Speed = distance/ time
Make distance the subject of formula
Since the time is second in one year and speed is ft/s, substitute both into the formula
Distance = speed × time
distance = 982,080,000 × 32,000,000
Distance = 3.142656 × 10^16 feet.
The distance of one light year in feet is 3.142656 × 10^16

a car travels 60 km in 2 hours 84 km the next 1 hour and then 68 km in 8.9 hours before reaching its destination what was the cars average speed in km / h
Answer:
17.8 km/hr
Explanation:
Average speed = distance / time
The total distance traveled is 60 km + 84 km + 68 km = 212 km.
The total time is 2 hr + 1 hr + 8.9 hr = 11.9 hr.
The average speed is 212 km / 11.9 hr = 17.8 km/hr

How is work related to force and displacement?
Answer:
Displacement is the distance and direction an object is moved. Force and work are directly proportional to each other, while force and displacement are indirectly propotional. The equation showing the relationship is W= Fd. OR Work is a scalar. The rate at which work is done or at which energy is transferred. Work is equal to the force parallel to the displacement.
Explanation:
Work is related to force and displacement as the work is the product of the displacement and the force.
What is work done?The total amount of energy transferred when a force is applied to move an object through some distance
The work done is the multiplication of applied force with displacement.
The SI unit of work done by an object is Joules.
IJ is the work done when a force of 1 N displaces an object by 1 m .
work is the product of displacement and force.
Work Done = Force * Displacement
For example, let us suppose a force of 100 N is used to displace an object by a displacement of 50 m then the work done on the object can be calculated by the above-mentioned formula
work done = 100 N ×50 m
=5000 N m
Thus, we can say the work done on an object depend on the force as well as the displacement, as the work is the product of the force and the displacement

A washing machine heats 10kg of water in each wash cycle. How much energy is saved by washing at 30'c instead of 50'c if the starting temperature of the cold water is 16'c? The specific heat capacity of water is 4200 J/Kg'c
The two equations you can use is in the picture.
8.4 × 10⁵ Joules of heat energy can be saved assuming that there is no heat exchange between the washing machine and the environment.
What is Heat energy?Heat energy is the result of movement of tiny particles called as atoms, molecules, or ions in solids, liquids and gas substances. Heat energy can be transferred from one object to another object.
Let m denote the mass of water and the specific heat capacity of water. The energy required to raise the temperature of that much water by would be:
Q = m × c × ΔT
Washing at 30°C would require a temperature change of
ΔT = 30°C - 16°C = 14°C
Washing at 50°C would require a temperature change of
ΔT = 50°C - 16°C = 34°C
In both situations, c = 4.2 × 10³J.kg/ °C while m = 10kg.
Calculate the energy required in either of the situations as:
Washing at 30°C:
Q(30°C) = c × m × ΔT
Q = 4.2 × 10³J.kg/ °C × 10kg × 14°C
Q = 588000 Joules
Washing at 50°C :
Q (50°C) = c × m × ΔT
Q = 4.2 × 10³J.kg/ °C × 10kg × 34°C
Q = 1428000 Joules
1428000 Joules - 588000 Joules = 8.4 × 10⁵ Joules
