Answer: A. 1.0 gallon of water
Explanation: to calculate the mass of each option, we have to note the unit conversations, and for the purposes of this question we will be using the density of the substance that is not under the condition of temperature or pressure, because we have option B which conditions of pressure and temperature are not stated.
For option A:
1gallon= 3.7854liters
Density= 1.0g/ml= 1000g/liters
mass= volume×Density
Therefore
Mass= 3.7854×1000= 3785gram
For option B:
5lb potatoes 1kg=2.2046lb
Therefore:
(5lb×1kg)/2.2046lb= 2.26798kg
Where 1kg=1000gram
(2.26798kg×1000g)/1kg= 2268grams
For option C:
1gallon=3.7854liters
Density=0.8g/ml= 800g/l
Therefore:
Mass= density×volume
Mass=800×3.7854=3028grams
For option D:
Mass= density×volume
Density= 800g/ml
Volume=3liters
Therefore mass=
800×3=2400grams
THEREFORE FROM THE OPTIONS ABOVE WE CAN SEE THAT OPTION A OF 1 GALLON OF WATER, HAS THE LARGEST MASS, WITH 3785grams
Answer:
His speed was 2 m/s, and his velocity was 0
Explanation:
In physics, speed of an object is defined as the change in position with the change in its time. While velocity may be defined as the change in the position of the body with respect to the time taken.
Speed in a scalar quantity which means it has only magnitude while velocity has both magnitude and direction.
To determine change in velocity both direction as well as magnitude has to be changed.
In the context, Kai was 200 m of the library in the north direction. Now for the round trip to the library and back to his position, Kai took 200 seconds time to cover the distance.
So for the round trip, the speed of Kai would be 2 m/s abut the velocity of Kai is 0 as the displacement of Kai is 0.
For the ones that don’t need numbers, I will put 1, but choose what you personally learnt:
(1), 2, 2, (1), 2
I believe putting 1 would be the best option I have, just incase
Within the visible range of light, red<span> light waves are scattered the least by atmospheric gas molecules. So at sunrise and </span>sunset, when the sunlight travels a long path through the atmosphere to reach our eyes, the blue light has been mostly removed, leaving mostly red<span> and yellow light remaining.</span>
