The north and west components of this displacement are 9.19 km and -7.71 km respectively.
<h3>
North component of the displacement</h3>
The north component of the displacement is calculated as follows;
Dy = D sinθ
Dy = 12 km x sin50
Dy = 9.19 km
<h3>West component of the displacement</h3>
Dx = D x cosθ
Dx = - 12 km x cos(50)
Dx = -7.71 km

You can find them in a chart but the atomic mass unit (amu) is defined as the proton mass. Proton = 1amu, neutron =1 amu, electron = 0.005amu
charge on P is +1, charge on N is 0, and charge on electron is -1
Answer:
Explanation:
Energy stored in spring = 1/2 k x²
80 = 1/2 x k .2²
k = 4000 N /m
Required force = k x
= 4000 x .2
=800 N
b )
Additional work done
= difference in stored elastic energy
= 1/2 k ( x₂² - x₁² )
= .5 x 4000 ( .4² - .2² )
= 240 J
Answer:
3.26mph
Explanation:
To calculate speed, use the formula distance/time. In this case, just divide 14.7 by 4.5.
