The statement that is true of thermometers is; The temperature reported by a thermometer is never precisely the same as its surroundings.
What is the function of thermometer in an experiment?In the experiment to determine the specific heat of a material, the theory will be one which explains that when a heat interchange takes place between two bodies that were having different temperatures at the beginning, the quantity of heat the warmer body looses is equal to that gained by the cooler body to reach the equilibrium temperature. This is true only if no heat is lost or gained from the surrounding.
Now, If heat is gained or lost from the surrounding environment, the temperature readings by the thermometer will be incorrect. The experimenter should therefore have in mind that for accurate results, the temperature recorded by the thermometer is similar to that of the surrounding at the beginning of the experiment and if it differs then note that heat is either gained or lost to the environment.

The horizontal part of a step is called the tread. the vertical part is called the riser. the recommended riser-to-tread ratio is 7 inches : 11 inches. a. find the value of x for stairs built using the recommended riser-to-tread ratio. round your answer to the nearest tenth.
The value of x for these stairs built by using the recommended riser-to-tread ratio is 32.5°.
Given the following data:
Length of riser = 7 inches.Length of tread = 11 inches.Ratio = 7:11.How to determine the value of x.In Mathematics, a tread refers to the horizontal part of a step while a riser is the vertical part of a step.
Note: Let the angle of inclination be x.
In Geometry, two (2) lines that are parallel have the same alternate interior angles. Thus, the angle of inclination between the riser and tread is given by:
[tex]Tan x = \frac{rise}{tread} \\\\Tan x = \frac{7}{11} \\\\Tan x = 0.6364\\\\x=tan^{-1}0.6364[/tex]
x = 32.5°.

Hugo plans to buy packs of baseball cards until he gets the card of his favorite player, but he only has enough money to buy at most 444 packs. suppose that each pack has probability 0.20.20, point, 2 of containing the card hugo is hoping for. let the random variable xxx be the number of packs of cards hugo buys. here is the probability distribution for xxx:
Considering the given discrete probability distribution, it is found that there is a 0.36 = 36% probability that Hugo buys fewer than 3 packs.
What is the discrete probability distribution?Researching on the internet, it is found that the discrete probability distribution for the number of packs that Hugo buys is given by:
P(X = 1) = 0.2.P(X = 2) = 0.16.P(X = 3) = 0.128.P(X = 4) = 0.512.The probability that he buys fewer than 3 packs is given by:
P(X < 3) = P(X = 1) + P(X = 2).
Hence:
P(X < 3) = P(X = 1) + P(X = 2) = 0.2 + 0.16 = 0.36.
There is a 0.36 = 36% probability that Hugo buys fewer than 3 packs.

Twelve identical point charges q are equally spaced around the circumference of a circle of radius r. the circle is centered at the origin. one of the twelve charges, which happens to be on the positive x axis, is now moved to the center of the circle.
There is only one net force acting on the charge at the center of the circle that will only be subjected to a repulsive force from the charge is extant on the negative axis of x.
What is a line charge?A line charge refers to the charge that is allocated along a curve that is one dimensional in nature such as a circle.
In physics experiments, line charges are used in wire chambers. Wire chambers are used for high-energy physics experiments.
In summary, the charges are put at equal distances around the circumference of the circle in the example.
Because the charges at the opposing ends of the circle are similar, they exert an equal-magnitude repelling force in the opposite direction on the charge at the center of the circle, thus balancing out the forces.
This is why there is only one net force acting on the charge at the center of the circle that will only be subjected to a repulsive force from the charge is extant on the negative axis of x.

The kinetic energy will be "0.5 J". To understand the calculation, check below.
Kinetic EnergyAccording to the question,
Mass or object, m = 10 N or,

Speed, v = 1 m/s
We know the formula,
→ Kinetic energy, K.E = [tex]\frac{1}{2}[/tex] mv²
By substituting the values, we get
= [tex]\frac{1}{2}[/tex] × 1 × (1)²
= [tex]\frac{1}{2}[/tex] × 1 × 1
= [tex]\frac{1}{2}[/tex]
