0.00000231 in scientific notation is

Answers

Answer:

2.31×10-⁶ is scientic notaion of 0.00000231

Final answer:

The number 0.00000231 is written as 2.31 x 10^-6 in scientific notation. Scientific notation represents numbers as a mantissa (between 1 and 10) multiplied by 10 raised to an exponent.

Explanation:

The number 0.00000231 in scientific notation is written as 2.31 x 10-6. In scientific notation, a number is represented as a number between 1 and 10 (known as the mantissa) multiplied by 10 raised to a power (the exponent). In this case, 2.31 is your mantissa and -6 is your exponent. The negative exponent indicates that the original number was less than 1, and the 6 indicates how many places the decimal was moved to the right to obtain the mantissa.

A model rocket rises from rest with constant acceleration of 106m/s2.what is the rocket speed at a height of 3.2m

Answers

At a height of 3.2 meters, the final speed of the model rocket is 26.05 m/s.

Given the following data:

Initial speed = 0 m/s (since the model rocket accelerated from rest).

Acceleration = 106 $m/s^2$

Distance (height) = 3.2 meters.

To find the final speed of the model rocket, we would use the third equation of motion;

$V^2 = U^2 + 2aS$

Where:

V is the final speed.

U is the initial speed.

a is the acceleration.

S is the displacement or distance covered.

Substituting the given parameters into the formula, we have;

$V^2 = 0^2 + 2(106)(3.2)\n\nV^2 = 0 + 678.4\n\nV = √(678.4)$

Final velocity, V = 26.05 m/s

Answers

45 kg * 9.8 m/s^2 = 441 N.

Answer:

The force of a mass's weight is defined as its mass * acceleration due to gravity.

On Earth, g is about 9.8 m/s^2. This will be the acceleration due to gravity.

Then, 45 kg * 9.8 m/s^2 = 441 N.

Explain how geographic features can cause local winds?

Answers

If there is a dip in the land the wind goes into there then the wind is trapped in the bowl shaped transformed so the wind is stronger inside the bowl shaped area than the area outside of the creator.

Answer:

All wind is caused by the uneven heating of Earth's surface, which sets convection currents in motion. Convection currents on a large scale cause global winds; convection currents on a small scale cause local winds.

Two cars start from rest at a red stop light. When the light turns green, both cars accelerate forward. The blue car accelerates uniformly at a rate of 5.8 m/s2 for 3.3 seconds. It then continues at a constant speed for 9.8 seconds, before applying the brakes such that the car’s speed decreases uniformly coming to rest 255.79 meters from where it started. The yellow car accelerates uniformly for the entire distance, finally catching the blue car just as the blue car comes to a stop.3)How far does the blue car travel before its brakes are applied to slow down?
