assume the east-west direction along the x-axis such that east lies in positive x-direction and west lie in negative Y-direction.
In unit-vector notation , individual displacement can be represented as
A = displacement of car in east direction = 60 i
B = displacement of car in west direction = - 90 i
D = total displacement of the car
Total displacement of the car is given as
D = A + B
inserting the values
D = 60 i + (- 90 i)
D = - 30 i
negative sign indicates the direction in west
hence net displacement is 30 km in west direction
<span>T1 = 20.0 + 273 = 293.0 K
T2 = 8.00 + 273 = 281.0 K
use the combined gas law
p1V1/T1 = p2V2/T2
765 x 580/ 293.0 = 440 V2/ 281-0
V2 = 967 mL</span>
Answer:
dependent: the outcome of the experience
independent variable: everything literaly.
Independent is where you change some variables and see the result
Dependent is literaly the result, or the outcome dependent on the exprience.
Explanation:
I got u.
Answer:
4
Explanation:
Given parameters:
Force input = 30N
Force output = 120N
Unknown:
Mechanical advantage of the lever = ?
Solution:
The mechanical advantage is the quantity that describes how much a simple machine is able to multiply force.
This is expressed as:
Mechanical advantage = Force output / Force input
Mechanical advantage = 
= 4
It would be thrust, so the first one
