Multiply the following numbers, using scientific notation and the correct amount of significant digits. 1.003 m⋅3.09 =

Blababa [14]

The correct answer to the question is: 3.10

CALCULATION:

As per the question, the two numbers are given as 1.003 and 3.09.

We are asked to multiply these two numbers.

The multiplication result of the two numbers = 1.003 × 3.09

= 3.09927.

We have to rewrite this result in terms of rule of significant digits.

The total number of significant digits of first number is 4.

The total number of significant digits of second number is 3.

Hence, the minimum number of significant digits is 3.

As per the significant rules for multiplication, the final result will follow the minimum number of significant digits.

Hence, the final answer should contain only three significant digits.

The multiplication result is rounded off after three significant digits.

The fourth significant digit is 9 which is to be rounded off.

As, it is greater than 5, so 1 will be added to the preceding digit.

Hence, the multipled result = 3.10

Hence, the correct answer of this question is 3.10

A speedboat initially at rest accelerates uniformly at 4.0 m/s (squared) for 7.0 s. How fast is the boat moving after 7.0 s?

zaharov [31]

Well if the boat initially at rest accelerates at uniformly at 4.0 m/s (squared) then it would be best to muitlply it so 4.0 squared equals 2 by multiplying that by 7.0 your answer would be 14 s

A student has a mass (including clothes and shoes) of 65.0 kg. She drinks a 12 oz. can of soda, with a nutritional energy conten

Stella [2.4K]

She can climb 0.92 m without losing weight.

<u>Explanation</u>:

Gravitational potential energy is the energy consisting of the product of mass, gravity and height.

1 cal = 4184 J

140 cal = 585760 J

Energy = 585760 J, m = 65.0 kg = 65000 g, Efficiency = 20 %

GPE = mgh

where m represents the mass

g represents the gravity,

h represents the height.

585760 = 65000 $\times$ 9.8 $\times$ h

h = 0.92 m.

Describe the organization of our solar system. What are the different divisions, or categories?

olasank [31]

Hello.

The solor system is organized by the smallest star to the largest and by the 8 planets. it is also organized by how much gas a planet has. But it is also orgainzed becasue of gravity.

The different divisions are <span>planets, moons, asteroids, comets and meteoroids.
