Answer:
2.31×10-⁶ is scientic notaion of 0.00000231
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.
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.

At a height of 3.2 meters, the final speed of the model rocket is 26.05 m/s.
Given the following data:
To find the final speed of the model rocket, we would use the third equation of motion;
Where:
Substituting the given parameters into the formula, we have;
Final velocity, V = 26.05 m/s

We can solve the problem by using the following equation:
where
vf is the final speed of the rocket
vi=0 is the initial speed of the rocket (it starts from rest)
is the rocket's acceleration
S=3.2 m is the distance covered by the rocket
Re-arranging the equation, we find the velocity of the rocket after 3.2 m:
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.
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.
