Beverly and Carl are in a race. Their graphs show the data Which best describes the race?A. Even though for a majority of the race they accelerated at the same rate, Carl won because his initial acceleration was greater than Beverly’s
B. Even though for a majority of the race they accelerated at the same rate, Beverly won because her initial acceleration was greater than Carl’s.
C.Beverly accelerated at a greater rate for the entire race.
D. Carl accelerated at a greater rate for the entire race
Answers
The correct option is B.
Acceleration is defined as the rate of velocity of a body per unit time; that is, acceleration is given by the ratio of velocity and time. Looking at the graph given above, it can be seen that, the two runners started with different initial velocity; Beverly started with the initial velocity of 15 m/s while Carl started with the initial velocity of 10 m/s. For the rest of the race, the two runners maintains similar acceleration but Beverly won because her initial velocity was higher.

Ok; first of all, you must correct the Molecular Formula; FeSO4•7H20
So, work out the Molar Mass;,
(4x18)O+ 55.? Iron + 32 Sulphur, PLUS
(7x 18) H2O = 1 molar mass.
Now, take that times 5.24, show your work & check the Mol. Weights, I am going by memory.

As the astronaut moved away from Earth, the gravitational force between Earth and the astronaut will decrease.
What is the gravitational force?
The gravitational force can be described as a force that attracts any two objects having mass. The gravitational force is an attractive force because it always tries to pull masses together, it never pushes objects apart.
In the universe, each object with mass attracts every other object with a certain force, and that attraction force is directly proportional to the product of the masses of those objects.
The objects that are far apart from each other, don't pull on each other but the force is there and we can calculate it from the Gravitational Force Formula,
F = Gm₁m₂/r²
Where F is the gravitational force between two objects, m₁ is the mass of the first object, m₂ is the mass of the second object and 'r' is the distance between the centers of two objects.
The earth pulls everything towards itself because of the gravitational force. As the astronaut moved away from the earth the influence gravitational force of the earth or gravity will decrease.
