What is 1.2 x 10^5 in standard form?
The standard form of the given exponential function is 120000.
By putting the number as a base and the number of repetitions as a little number to its upper right, a representation of repeated multiplications of the same number is known as an exponential form.
It is simpler to write repeated multiplication using base and exponents in the exponential form.
The equation f(x) = aˣ, in which the input variable x appears as an exponent and a as the base, describes an exponential function.
So, the given exponential function is,
1.2 x 10⁵
Here, 10 is the base and 5 is the exponent.
10⁵ = 100000
Therefore, the standard form of the given equation is,
1.2 x 100000 = 120000

Year wise Percentage of Attendance in Senior Secondary Schools of India The given graph shows that the percentage of attendance is recorded with a gap of 5 years. The given table depicts, across time, from the year 2000 to 2015. During the 15 years, there is a steady and healthy increase in the percentage of attendance in ll the four types of schools. The increase in Convent-run schools is much higher compared to the other three types of schools. Initially, the village schools show a noticeably poor percentage of attendance and the General English Medium schools show less percentage of attendance compared to the Convent-run schools. All in all the continuous higher percentage indicates that the relevant authorities are learned about improving the education of the country. The poor attendance in the 2010 in the Government-run village schools shows a big leap in the year 2015, indicating that the Government must have taken an effective measure to improve literacy in the villages. Noteworthy increase in the attendance indicates solid infrastructure and focus towards the healthy growth of the corresponding authorities.

A 14-gauge copper wire of diameter 1.628 mm carries a current of 12.5 What is the potential difference across a 2.00 - m length of the wire? *p=1.47x10^-8
Answer:
[tex]V=1.76\times 10^{-4}\ V[/tex]
Explanation:
Given that,
The diameter of a wire, d = 1.628 mm
Radius, r = 0.814 mm = 0.000814m
Current, I = 12.5 mA
The length of the wire, l = 2m
The resistivity of the wire, [tex]\rho=1.47\times 10^{-8}\ \Omega-m[/tex]
We need to find the potential difference across the wire. We know that the resistance of the wire is given by :
[tex]R=\rho\dfrac{l}{A}[/tex]
Also, V = IR
[tex]\dfrac{V}{I}=\rho\dfrac{l}{A}\\\\V=\dfrac{\rho l I}{A}\\\\V=\dfrac{1.47\times 10^{-8}\times 2\times 12.5\times 10^{-3}}{\pi \times (0.000814)^2}\\\\V=1.76\times 10^{-4}\ V[/tex]
So, the potential difference of the wire is [tex]1.76\times 10^{-4}\ V[/tex].

Answer:

Explanation:
The velocity does not change greatly between Mars and Venus —explained Dong— but Venus's closer proximity to the sun boosts the density by almost a factor of 4.5. This would mean that atmosphere on Mars would be lost even more rapidly than at its current position.

Why is it important for body cell to have twice and many chromosomes as sex cells?
Answer:
Why sex cells only need half the number of chromosomes compared to other cells in the body? As gametes are produced, the number of chromosomes must be reduced by half. Why? The zygote must contain genetic information from the mother and from the father, so the gametes must contain half of the chromosomes found in normal body cells.

How long does it take a 100 kg rocket to increase speed from 10
m/s to 200 m/s with a force of 250N?
Answer:
76 seconds
Explanation:
Using the formula t=vf-vo/a, where t=time, vf= final velocity, v0= initial velocity, and a= acceleration, we can solve for your problem.
Plug in known variables...
t=200-10/a
we can solve for a by using the formula F=ma where f=force, m= mass, and a=acceleration and rearranging it to solve for a.
a=F/m
Plug in known variables...
a=250N/100kg
a=2.5m/s^2
Plug in our newly found acceleration of 2.5 m/s^2 into our first equation and solve....
t=190/2.5
t=76 seconds

Answer:
The most correct option for the magnitude of the velocity of the ship relative to the port is;
33 km/h
Explanation:
The given parameters of the cargo ship are;
The speed of the cargo ship = 25 km/h
The direction of the cargo ship, θ₁ = 20° North of East
The speed of the current = 10 km/h
The direction of the current, θ₂ = 15° North of East relative to the port
Therefore the direction of the ship relative to the port, 'θ', is given as the sum of θ₁ and θ₂ as follows;
θ = θ₁ + θ₂ = 20° + 15° = 35°
The component of the velocities relative to the port are given as follows;
The velocity of the ship, v₁ = 25·cos(35°)·i + 25·sin(35°)·j
The velocity of the current , v₂ = 10·cos(15°)·i + 10·sin(15°)·j
The velocity of the ship relative to the port, v = (25·cos(35°) + 10·cos(15°))·i + (25·sin(35°) + 10·sin(15°))·j
∴ v ≈ 30.14·i + 16.93·j
The magnitude of 'v' is [tex]\left | v \right |[/tex] = √(30.14² + 16.93²) ≈ 34.6
Therefore, the magnitude of the velocity of the ship relative to the port, [tex]\left | v \right |[/tex] ≈ 34.6 km/h.
Therefore, the closest correct option for the velocity of the ship relative to the port is 33 km/h
Answer:
The correct option for the magnitude of the velocity of the ship relative to the port is...
(33 km/h)

The kinetic energy that the plane had is now gone. In keeping with the Law of Conservation of Energy, which of the following is the most likely explaination of what happened to that energy?
The brakes used a coil system to convert the kinetic energy into potential energy stored in the brakes
The kinetic energy of the plane gets pushed into the air in front of it due to drag forces, causing the air to move, thus transferring the kinetic energy from the plane to the air
The brakes create friction, which transformed the kinetic energy to heat energy that was dissipated to the surroundings
The kinetic energy is being converted into sound energy by the loud engines of the plane

Answer:
Your displacement is 15.62m NW
Explanation:
We can use the Phytagorean theorem to determine the displacement:
a^2+b^2=c^2
12^2+10^2=c^2
144+100=c^2
244=c^2
15.62=c

Answer:
The answer to your question should be D.
Explanation:
reactants are on the laft side of arrow and products are on right side of arrow
The option that best represents a chemical reaction is Reactants → products. Thus, the correct option for this question is D.
What is a Chemical reaction?A chemical reaction may be defined as a methodology through which one or more substances that are also called reactants, are significantly transformed into one or more different substances which are known as products.
The involvement of these reactants and products are either chemical elements or compounds. The mass of the chemical reaction remains the same but the state of matter may be altered. Some chemical reactions also involved the utilization of catalysts in order to proceed with the reaction fast by lowering its activation energy.
Therefore, reactants → products is an option that best represents a chemical reaction. Thus, the correct option for this question is D.
