Answer:
Ф,
Ф
Explanation:
Now find the components NxNxN_x and NyNyN_y of N⃗ N→N_vec in the tilted coordinate system of Part B. Express your answer in terms of the length of the vector NNN and the angle θθtheta, with the components separated by a comma.
Vectors are quantities that have both magnitude and direction while scalar quantities have only magnitude but no direction.
This a vector quantity
from the diagram the horizontal component of the length of the vector will be
Ф
the vertical component will be
Ф
this is in the opposite direction because the x can be extrapolated to the negative axis
Appproximately 10% of those who suffer from anorexia nervosa literally starve themselves to death.
Solution:
In this question we have given,
initial velocity,u = 0
final velocity, v = 1m/s
displacement =.5mm (Because 1mm=.001m)
We have to find
1.acceleration
2. Time
1. we know third equation of motion is given as,
............(1)
Put values of v,u and s in equation (1)
![[tex]s=1^{2} = 0^{2} +2X.0005Xa\\1= .001a\\therefore, a = 1/.001\\ a= 1000m/s^{2}](https://tex.z-dn.net/?f=%5Btex%5Ds%3D1%5E%7B2%7D%20%3D%200%5E%7B2%7D%20%2B2X.0005Xa%5C%5C1%3D%20.001a%5C%5Ctherefore%2C%20a%20%3D%201%2F.001%5C%5C%20a%3D%201000m%2Fs%5E%7B2%7D)
2. We know First equation of motion is given as
......................(2)
put values of v, u and a in equation(2)
Answer:
K = U ( b )
Explanation:
The expression that describes the kinetic and potential energies at the point mid-way between to the highest and lowest points is K = U
this is because at the midpoint between the highest point and the lowest point the height is expressed as( h/2) therefore potential energy at that point is expressed as m*g*h/2 therefore the remaining energy at this point will be considered the kinetic energy which will be = m*g*h/2 as well hence at midpoint Kinetic energy = potential energy
D. Substances that atoms make up.
