Answer:I think its the first one
Explanation:
Yes. Here is my explaination: Peer pressure is a complicated area. On one hand, it can help your child develop the coping skills necessary for adulthood. It can also, however, lead them in bad directions. While teens may feel they have “grown up,” their brains are not finished developing and one of the immature functions is judgment. Peer pressure might encourage teens to become more active in athletics or to avoid risky behaviors. Or it could lead them to try alcohol or drugs, skip school or engage in other negative behaviors.
HOPE THIS HELPS TO ANSWER YOUR QN!
If electrons move away from 'A', then 'A' becomes less negatively (or more positively) charged than it was originally.
If electrons move onto 'B', then 'B' becomes more negatively (or less positively) charged than it was originally.
Answer:
h~=371.26m
Explanation:
when an object falls we use the equations of accelerated motion. There is only one that gives distance.
Since we have no initial velocity (started from rest) we can get rid of the (ut) term
where a we substitute g (gravitational acceleration, constant for given heights and almost 9.81m/s^2).
Given, m1 = 3.50 g
m2 = 5.5 g
r₁=(3i^ + 3j^)t + 2j^ t²
r₂ =3i^ - 2j^t² - 6j^t
t = 2.50 sec.
Now the position of the center of mass is,
The velocity of the center of mass = (m₁r₁+m₂r₂)/(m₁+m₂)
= {3.5[(3i^ + 3j^)t + 2j^ t²]+5.5[3i^ - 2j^t² - 6j^t]}/(3.5+5.5)
= (-2.89i^-1.39j^)cm
So the velocity of the center of mass = (-2.89i^-1.39j^)cm
What is Velocity?
Velocity is the directional speed of an object in motion as an indication of its rate of change in position as observed from a particular frame of reference and as measured by a particular standard of time. Velocity is a fundamental concept in kinematics, the branch of classical mechanics that describes the motion of bodies.
What is the Center of mass?
In physics, the center of mass of distribution in space (sometimes referred to as the balance point) is the unique point where the weighted relative position of the distributed mass sums to zero. This is the point at which a force may be applied to cause a linear acceleration without an angular acceleration.
What is the velocity of a particle?
The velocity of a particle is its speed and the direction in which it's moving. It is also described as the instantaneous rate of change of the particle's distance traveled and the direction in which the distance is changing.
