Answer:
It will take 2.68 minutes for them to reach each other.
Explanation:
We use the two following kinematic equations, making the final position the same (for the moment they meet each other):
locomotive 1 --> 
locomotive 2 --> 
we make the two xf equal, and solve for the time (t) using v = 95 km/h:
converting the hours into minutes by multiplying this value times 60;
t = 2.68 minutes
Carnivores like lions, wolves, cheetahs and leopards are also found in temperate grasslands. Other animals of this region include deer, prairie dogs, mice, jack rabbits, skunks, coyotes, snakes, foxes, owls, badgers, blackbirds, grasshoppers, meadowlarks, sparrows, quails, hawks and hyenas.
Answer: #.37 times greater
Explanation: Volume of a sphere is: V = 
·π·r³
Since it is given the diameter of the basketball and the softball, their ratios are r₁ = 3in and r₂ = 2in, in which index 1 represents the basketball and index 2, the softball.
Calculating the volume of basketball:
V₁ = . 3.14 . 3³
V₁ = 113.04 in³
Calculating the volume of softball:
V₂ = . 3.14 . 2³
V₂ = 33.5 in³
Comparing one volume with the other:
= 
= 3.37
We have that V₁ = 3.37V₂
This means the volume of a basketball is 3.37 times greater than the volume of a softball.
Answer with Explanations:
Given:
Mass of object, m = 100 lb
height fallen, h = 600 ft
initial velocity, u = 50 ft/s
acceleration due to gravity, g = 31.5 ft/s^2
Find final velocity when it touches ground.
Solution:
Use standard kinematics equation, in the absence of air resistance and variation of g with height,
v^2 - u^2 = 2aS
where
v = final velocity
u = initial velocity
a = acceleration due to gravity
S = distance travelled
Substitute values
v^2 = u^2 + 2aS
= 50^2 + 2*31.5*600
= 40300 ft^2/s^2
Final velocity,
v = sqrt(40300) ft/s
= 200.75 ft/s
= 201 ft/s to the nearest foot.
Mechanical weathering is the process of breaking big rocks into little ones. This process usually happens near the surface of the planet. Temperature also affects the land. The cool nights and hot days always cause things to expand and contract. That movement can cause rocks to crack and break apart.
Chemical weathering occurs when chemical reactions weaken and decompose rocks, often acting alongside the physical breakdown of rock, aka mechanical weathering. This process involves a chemical change, which actually alters the rock's or mineral's chemical composition.
