Answer:
Tangential acceleration is in the direction of velocity - along the circumference of a circle if the object is undergoing circular motion
a = (V2 - V1) / T
Radial acceleration is perpendicular to the direction of motion if the object is not moving in a straight line (perhaps along the circumference of a circle)
a = m V^2 / R = m ω^2 R where R is the radius vector of the velocity - note that the Radius vector is directed from the center of motion to the object and for circular motion would be constant in magnitude but not in direction
Answer:
A pure substance (an element or a compound) is made up of only one type of atom, or molecule.
Examples: water (H2O molecules), oxygen (O2 molecules), argon (Ar atoms).
A mixture is made of up of more than one type of atom or molecule.
Examples: salt water (H2O molecules, Na+ ions, Cl- ions),
air (N2 molecules, O2 molecules, Ar atoms, CO2 molecules)
Note: the composition of a pure substance is fixed, but the composition of a mixture can vary. Two salt water solutions might not have the same concentration of salt. Or, if you prefer, one blueberry muffin might have more blueberries in it than another blueberry muffin.

Answer:
m/s
Explanation:
Assumptions: 0° is true North, and 90° is east (along the x-axis).
To solve this problem we must use the expression:
Where 
is the velocity in the y-direction (East), 
is the total velocity in the direction which the aircraft is travelling, and 
is the direction the aircraft is travelling (angle from the y-axis).
Using the equation above, we obtain the y-component of velocity
m/s which is rounded to 227 m/s (due to the number of significant figures in the question).
Answer:
coronal mass ejection
Explanation:
Solar wind is something that has to do with magnetism,
CME is " is a significant release of plasma and accompanying magnetic field from the solar corona," that often follows solar flares.
