Answer:

Answer:

Earth has one moon, and there are more than 200 moons in our solar system. Most of the major planets – all except Mercury and Venus – have moons. Pluto and some other dwarf planets, as well as many asteroids, also have small moons.

Answer: 4.6 minutes

Explanation:

(254 mi/hr) x (1hr/60min)= 4.23 mi/min

(19.5mi) x (1min/4.23mi)= 4.6 minutes

When the fastest and longest skydive fell an amazing 19.5 miles. His average speed while falling was 254 mi/hr, then the dive lasted for 276.377 seconds

The total distance covered by any object per unit of time is known as speed. It depends only on the magnitude of the moving object. The unit of speed is meter/second. The generally considered unit for speed is a meter per second.

The mathematical expression for speed is given by

speed = total distance /Total time

As given in the problem The fastest and longest skydive fell an amazing 19.5 miles. His average speed while falling was 254 mi/hr

Total distance = 19.5 miles

Total time =?

average speed

By substituting respective values in the formula of speed

254 mi/hr = 19.5 miles/time

time = 19.5/254 hr

time = 0.0767716 hr

As we know 1 hr = 3600 seconds

0.0767716 hr = 0.0767716 ×3600 seconds

                       =276.377 seconds

Thus, the dive lasted for 276.377 seconds

Explanation:

T = 1/f = .01

Answer:

what do this even say

Explanation:

The absolute zero temperature is the smallest thermodynamic thermal limit, which is considered as a zero kelvin when the enthalpy, as well as the entropy of a cooled ideal gas, are of minimal value.

It is expressed by using the formula:

[tex]\mathbf{T_{abs} = T_N + k}[/tex]

where;

[tex]\mathbf{T_{abs } = absoulte \ temperature}[/tex]

[tex]\mathbf{T_N = temperature \ at \Neptune \ Scale}[/tex]

k = factor to convert temperature from absolute scale to Neptunian scale

N:B: An absolute temperature = zero (0) kelvin

From the information given, Using Ideal gas since it is used in Neptune:

PV = nRT

where;

From the question, provided that the gas is the same and no new mass is added;

Then, we can equate the moles of gas in the given conditions as;

[tex]\mathbf{\dfrac{P_1V_1}{T_1}=\dfrac{P_2V_2}{T_2}....\dfrac{P_nV_n}{T_n}}[/tex]

Using:

[tex]\mathbf{\dfrac{P_1V_1}{T_1}=\dfrac{P_2V_2}{T_2}}[/tex]

where the value of;

P₁V₁ = 28 dm³ atm

T₁ = 0⁰ N

P₂V₂ = 40dm³ atm

T₂ =  100⁰ N

∴

[tex]\mathbf{\dfrac{28}{(0+K)}=\dfrac{40}{(K+100)}}[/tex]

By cross multiply;

28(K+100) = 40(0+K)

28K + 2800  = 0 + 40K

40K - 28K = 2800

12 K = 2800

K = 2800/12

K = 233.33° N

Recall that:

[tex]\mathbf{T_{abs} = T_N + k}[/tex]

[tex]\mathbf{0= T_N+ 233.33 ^0 N}[/tex]

[tex]\mathbf{ T_N= - 233.33 ^0 N}[/tex]

Therefore, we can conclude that the value of the absolute zero of temperature on their temperature scale is -233.33° N

The car’s average velocity is mathematically given as

V=4m/s

Average velocity is simply the mean rate of change of position of a car over a period of different times and this can be used to attain velocity of a car that has been in different velocity states

Generally, the equation for the Velocity   is mathematically given as

V=(AI/OI)

Therefore

V=24/1

V=4m/s

Answer:

Through the testing of hypotheses.

[tex]\\ \rm\longmapsto I=\dfrac{Q}{t}[/tex]

[tex]\\ \rm\longmapsto Q=It[/tex]

[tex]\\ \rm\longmapsto Q=2.72\times 9.88[/tex]

[tex]\\ \rm\longmapsto Q=26.87C[/tex]

The amount of charge that flows past a point in the wire during that time is approximately 26.8976 Coulombs.

Electric charge is quantized, meaning it exists in discrete amounts and is measured in coulombs (C). The elementary charge, represented by the symbol "e," is the charge of a single proton or electron, approximately equal to 1.602 x 10^-19 coulombs. Protons carry a positive charge, while electrons carry an equal but opposite negative charge.

When electric charges are stationary, they create an electric field around them. When charges are in motion, they produce a magnetic field in addition to the electric field, leading to electromagnetic effects.

Charge is a fundamental property of matter that determines its interaction with electric and magnetic fields and is crucial to understanding and explaining various electrical and electromagnetic phenomena in the natural world.

To calculate the amount of charge that flows past a point in the wire use the equation:

Q = I * t

Where:

Q is the charge (in Coulombs)

I is the current (in Amperes)

t is the time (in seconds)

Given:

Current (I) = 2.72 A

Time (t) = 9.88 s

Substitute these values into the equation to find the charge:

Q = I t

Q = 2.72 A * 9.88 s

Calculating the product:

Q = 26.8976 C

Therefore, the amount of charge that flows past a point in the wire during that time is approximately 26.8976 Coulombs.
