A crooked casino creates a 6-sided die with unequal probabilities. the probability of rolling a one is twice that of rolling any other number. a) what is the probability of rolling a 1?
Answers
The probability of rolling a one is twice that of rolling any other number.
Then the probability of rolling a 1 is 1/6.
What is probability ?The probability of something is how likely it is to happen. When we don't know how an event will turn out, we can talk about the probabilities of several outcomes—how likely they are. Examining events with a probability component is known as statistics.
Probability is a mathematical concept used to determine the likelihood of an event. It is challenging to make an accurate prediction for many events. We can only predict an event's likelihood, or how probable it is to occur, by using it.

Answers
To tighten the bolt to 35 Nm, a force of 2.03 N must be exerted with a lever arm of 21.65 cm. The required torque is 44.03 Ncm in the clockwise direction.
Given that the torque required to tighten the bolt is 35 Nm, the length of the wrench is 25 cm and the angle between the handle and the wrench is 60 degrees. We need to find the lever arm, the force to be exerted, the torque needed to be applied, and its direction. We will use the following formulas to solve the problem.Lever Arm: L = r sin θwhere L is the lever arm, r is the length of the wrench and θ is the angle between the wrench and the handle.L = 25 sin 60° = 21.65 cmForce: F = T/r sin θ, where F is the force, T is the torque, and r and θ are defined as earlier. F = (35 Nm) / (25 cm sin 60°) = 2.03 N. Required Torque: T = F x L, where T is the required torque and F and L are defined as earlier.T = (2.03 N) (21.65 cm) = 44.03 N cmThe direction of the torque needed to be applied on the bolt to keep it in equilibrium is clockwise since the wrench is rotated in a clockwise direction. Therefore, to tighten the bolt to 35 Nm, a force of 2.03 N must be exerted on the wrench, which has a lever arm of 21.65 cm. A torque of 44.03 Ncm must be applied in the clockwise direction.For more questions on torque

Part B
What is the maximum force per unit length that could be achieved by reorienting the wire in this field? in (N/m)
Express your answer using two significant figures.
Answers
The magnetic field strength is 10.4 mT.
The maximum force per unit length that could be achieved by reorienting the wire in this field is 0.187 N/m
Find magnetic field strength and force?The magnetic force per unit length of wire is given by the formula:F = BILsinθ
where:
B = magnetic field strength
I = current
L = length of wire
θ = angle between the wire and magnetic field
Substituting the given values, we get:
0.35 N/m = B x 18 A x L x sin(24°)
Since we are asked to find the magnetic field strength, we can rearrange the equation as follows:
B = 0.35 N/m / (18 A x L x sin(24°))
We don't have the value of L, but we can assume it to be 1 meter since it doesn't affect the magnetic field strength. Substituting this value and solving for B, we get:
B = 0.35 N/m / (18 A x 1 m x sin(24°))
B = 10.4 mT (rounded to two significant figures)
Therefore, the magnetic field strength is 10.4 mT.
The maximum force per unit length can be achieved when the wire is perpendicular to the magnetic field, i.e., when θ = 90°. In this case, the magnetic force per unit length can be calculated as follows:F = BILsin90°
F = BIL
Substituting the given values, we get:
F = 10.4 mT x 18 A x 1 m
F = 187.2 μN/m
Converting this to newtons per meter, we get:
F = 187.2 μN/m x 10^-6 N/μN
F = 0.187 N/m (rounded to two significant figures)
Therefore, the maximum force per unit length that could be achieved by reorienting the wire in this field is 0.187 N/m.

Hope this helps have a awesome night/day❤️✨
Explanation:
Nothing, until those two objects physically touch each other; contact aligns polarity among the now single shared mass.
(Your question never states if both objects are unique or similar polar charges, so I just assumed they were both neutral objects existing within an electric field.)
So a better question would then be, what is gravity’s relationship with an electric field?
You could solve this with the following: confine the electric field’s volume to a set variable (never increasing nor decreasing in size or shape); density is variable and easily definable. This creates the limit to build upon. This density has to be fluid and has electron mass (full of electrons at rest mass, so with substance but no movement). Within, create a closed system (the hard part in this equation; outside interference like ambient light will eschew results) where each variable of kinetic energy then is accounted for or measurable (including heat and light, and the physical movement of the two objects)
Determine the mass for both objects, calculate gravity for both and each body’s inertia on the other as a sum over distance. record results. Polarity is shared across the masses until there is no longer inertia (one mass or contact).

Answer:
Option 3. The tennis ball began from rest and rolls at a rate of 14.7 m/s safer 1.5 seconds.
Explanation:
To know the the correct answer to the question, it is important that we know the definition of acceleration.
Acceleration can simply be defined as the rate of change of velocity with time. Mathematically, it is expressed as:
a = (v – u) /t
Where
a => acceleration
v => final velocity
u => Initial velocity
t => time
With the above information in mind, let us consider the options given in the question above to know which conform to the difinition of acceleration.
For Option 1,
We were told that the tennis ball has the following:
Distance = 4 m
Time = 1.5 s
This talks about the speed and not the acceleration.
Speed = distance / time
For Option 2,
We were only told about the average speed and nothing else.
For Option 3,
We were told that the tennis ball have the following:
Initial velocity (u) = 0 m/s
Final velocity (v) = 14.7 m/s
Time = 1.5 s
This talks about the acceleration.
a = (v – u) /t
For Option 4,
We were only told that the tennis rolls to the right at an average speed. This talks about the average velocity. We need more information like time to justify the acceleration.
From the above illustrations, option 3 gives the correct answer to the question.
Si observamos un incremento de temperatura en un termómetro de 24 oC, ¿a cuántos grados Fahrenheit corresponde dicho incremento? ¿Y si el incremento de temperatura fuese de 24 K?
Answers
Responder:
24 ° C = 75.2 ° F 24K = -416.47 ° FExplicación:
La fórmula se utiliza para convertir grados Celsius (° C) en grados Fahrenheit (° F).
x ° C = (y ° F - 32) × 5/9.
Convertir 24 ° C a Fahrenheit
24 = (y ° F - 32) × 5/9.
24 * 9 = 5 (y ° F-32)
216 = 5 años ° F-160
5 ° F = 216 + 160
5 ° F = 376
y ° F = 376/5
y ° F = 75.2
24 ° C = 75.2 ° F
Para convertir Kelvin a Fahrenheit, usaremos la expresión;
(K - 273.15) × 9/5 + 32
Dado K = 24kelvin
24K a ° F = (24− 273.15) × 9/5 + 32
= -249.15 (9/5) + 32
