Only particles that possesses enough energy to overcome the activation energy and orientated correctly will collide and form products. How about those particles which do not possesses enough kinetic energy to overcome the activation barrier? Does it mean that for a particular chemical reaction...

I'm confused about in phase and definite phase relationships. Please correct me if I am wrong. 1. Two waves of 360 degree phase difference are in phase. 2. Two waves that are 180 degree out of phase are classified as having definite phase relationships.

Homework Statement When there is a changing magnetic flux, emf is induced in the solenoid. The solenoid is made up of circular loops of wire. My first question is, since emd is induced in the solenoid, is there a site of higher voltage and another site of lower voltage? My second question is...

I understand now. Thank you so much :smile:

Homework Statement Does hall voltage disappear after the electric force on charge carriers balance the magnetic force? Homework Equations qE=qvB The Attempt at a Solution My understanding: By placing a current-carrying conductor in a uniform magnetic field, magnetic force is exerted on the...

If I throw a ball straight up, the direction of initial velocity will be upwards. Since the ball is slowing down, it's a deceleration and negative acceleration, so it's downwards. Thank you very much :D I now understood why the direction of acceleration is opposite to that of the initial...

I still got s= 3.56 x10^-4m. May I know why s is positive as I have already taken downward direction as positive? In the sketch that I posted, the electric field is directed from positive to negative, that is downwards. Electron is directed towards the positive plate. Hence acceleration is in...

This is my observation. The electric field is directed from positive to negative. The electron will accelerate towards to positive side. But I don't get why the direction of initial velocity can be opposite to that of the acceleration,

Homework Statement An electron has an initial velocity of 5.00 x 10^6 m/s in a uniform 2.00 x 10^5 N/C strength electric field. The field accelerates the electron in the direction opposite to its initial velocity. (a) What is the direction of the electric field? (b) How far does the electron...

Alright. Thank you very much[emoji5]️

So if the object is moving in opposite direction but it is slowing down, hence it has positive acceleration?

Homework Statement What is the acceleration of a body which is moving in opposite direction(assuming negative velocity) and is speeding up? Homework Equations acceleration=the rate of which an object changes its velocity The Attempt at a Solution In my opinion, an object moves with a negative...

1. The problem statement, all variables and given/known Spring constant of trampoline and cradle Homework Equations k=F/x The Attempt at a Solution I think a trampoline should have a low spring constant so that the extension is bigger. Is this correct? For cradle, in my opinion, it should have...

Thanks a lot to stockzahn, andrevdh and BvU for helping![emoji16][emoji5]️
