Answer:
Explanation:
The force acting on the block along the plane = mg Sin 45 = 0.707 x mg
The normal force acting on the block = mg Cos 45 = 0.707 x mg
Here, both the forces are equal in magnitude and the direction is different.
The net force is acting along the plane and the normal force is acting perpendicular to the plane.
The statement that weather differs from climate in that
weather can change on a daily basis and is not considered a description of
year-to-year conditions of temperature and
precipitation is true. While the
climate pertains to the atmospheric conditions over long periods of time.
Yes, that is the correct answer and work
The answer is A: Core --> Mantle --> Crust.
Core: The earth's core is the center of the earth, which would ultimately be the deepest. The core is made up of alloy, which is a mixture of many medals, such as iron and nickel.
Mantle: The earth's mantle is the layer between the earths crust and core. Often made of silicate rocks.
Crust: The earth's crust is the outer-most of the three options. Usually made of up different types of rocks.
Answer:
The minimum time taken is 3.84 s.
Explanation:
The expression for the equation of motion is as follows;
v= u+at
Here, v is the final speed, u is the initial speed, a is the acceleration and t is the time.
Convert the initial speed from to .
Convert the final speed from to .
It is given in the problem that The brakes on your automobile are capable of creating a deceleration of . The sign of the acceleration is negative here as there is deceleration.
Calculate the minimum time by using equation of motion.
v= u+at
Put , and
21.11= 39.17+(-4.7)t
t= 3.84 s
Therefore, the minimum time taken is 3.84 s.
