The data must be reproducible: it means that the data will be reliable and representative and not that this data would lead to one conclusion and another data would lead to another.

Data being varied, unique or surprising does not have anything to do with acceptability of the conclusion.

Yosemite Sam was sailing his ship at a speed of 67 m/s when suddenly a storm accelerated his boat at a rate of 5.4 m/s^2 over a

Afina-wow [57]

Answer: vf= 364 m/s

Explanation: Use the formula for acceleration:

a= vf - vi / t

Derive for vf:

vf =( at )+ vi

= 5.4 m/s² ( 55s) + 67 m/s

= 364 m/s

Which of the following accurately describe some aspect of gravitational waves? Select all that apply. (A) Gravitational waves co

crimeas [40]

Explanation :

The points regarding the gravitational waves are as follows :

(1) Gravitational waves are predicted to travel through space at the speed of light. So, the speed of gravitational waves is also equals $c=3\times 10^8\ m/s$ .

(2) The first direct detection of gravitational waves came in 2015. It is detected using a advanced LIGO detectors.

(3) The existence of gravitational waves is predicted by Einstein's general theory of relativity.

Hence, the correct options are (B), (D) and (E).

A cement factory emits 900 kilograms of CO2 to produce 1,000 kilograms of cement. A fully grown tree removes six kilograms of CO

Ierofanga [76]

Since the factory will be producing 100,000 kilograms of cement, using the relation 1000 kg of cement = 900 kg of CO2, then the factory will be emitting 90,000 kg of CO2 at the same time. To counteract the emission, a tree can remove 6 kg of CO2 per day. Dividing 90,000 kg by 6 kg to know the number of trees, we need 15000 trees to counter the emission. Since 1 acre of land holds 200 trees, we need 75 acres of land to hold the 15000 trees.
