Their science is just chem and physics don’t know man
Answer:
Velocity is defined as a vector measurement of the rate and direction of motion. Put simply, velocity is the speed at which something moves in one direction. The speed of a car traveling north on a major freeway and the speed a rocket launching into space can both be measured using velocity.
AND
Examples:
Revolution of Earth around the sun.
Revolution of moon around the earth.
Velocity of a satellite around the earth.
Velocity of a car while driving.
Velocity of a ball when hitted with a bat.
Velocity of water coming from a tap.
Velocity of the train .
Characteristic velocity or , or C-star is a measure of the combustion performance of a rocket engine independent of nozzle performance, and is used to compare different propellants and propulsion systems.. Formula = ˙ is the characteristic velocity (e.g. m/s, ft/s) is the chamber pressure (e.g. Pa, psi)
Answer and Explanation:
Given equation C = $600 billion +0.9Y
Where c = total consumer spending
$600 billion = consumer autonomous spendinf
0.9= marginal propensity to consume(mpc)
Y= income of consumers
A. Marginal propensity to consume(MPC)= 0.9 from equation given
B. Autonomous spending which is spending that is constant =$600 billion from equation given
C. Using equation of consumer spending above, C= $600 billion+0.9Y
With $4200 billion in income, consumers spending =$600 billion+0.9*$4200 billion
=$4380 billion
D. Savings= consumers income-consumers spending= $4200 billion-$4380 billion= -$180 billion
Therefore there was a deficit not saving
