Answer:
disease are carried by the blood
Answer:
v = 80.48 km/h.
Explanation:
We have,
Acceleration of a train is 2 km/h/s or 7200 km/h²
Initial velocity of a train is 20 km/h
It is required to find the velocity after 30 seconds or 0.0084 h
Let v is the final speed. Using equation of kinematics as :
So, the final speed of the train is 80.48 km/h.
Answer:
What is velocity?
v = d/t = distance / time you need to know this formula !
= 10 m/ 4 s = 2.5 m/s
Explanation:
The equation used to calculate the weight of an object on a plant is F = ma. "F" is the force measures in Newtons, "m" is the mass measures in grams and "a" is the acceleration that accur due to gravity.
Answer:
A building where the boy is on the 12 floor
Explanation:
The equation of the height or position takes into account the initial conditions.
So the general equation is
x(t) = at+c
When you solve with the initial conditions t=0 you will find the position at the begining, so this is c the constant.
in our initial equation we have 95 as the constant. and this is a equation to find height so the initial height is 95feets.
Now a common building has a distance of 7.5 feet between every floor.
You divide 95 by 7.5 and you will find 12.6
