Answer:
Generally given that the electric field is negative it mean that its direction is opposite to that of the force
Explanation:
From the question we are told that
The charge on the small object is 
The force is 
Generally the magnitude of the electric field is mathematically represented as
=> 
=>
Generally given that the electric field is negative it mean that its direction is opposite to that of the force
Answer:m1v1 + m2v2 = (m1f + m2f)vf. 3000kg(10.0m/s) + (15000kg)(0.0m/s) = (18000kg)(vf).
Explanation:
Answer:
#Where 
is in meters and 
in seconds.
Explanation:
Given that :
From 
we have:
From 
we have that:
Now,given that the initial value problem is given by:
Hence,the position of u at time t is given by
, in meters, in seconds.
It creates a white crystal salt MgF2
Answer: a) 0.12m; b) 1,6 s; c) 0.625 1/s
Explanation: The simple harmonic movement can be described by a sin or cosine function in time.
This can be in the form:
X(t)= A Sin/Cos (wt+φ) where φ is initial phase o position at t=0
w the angular frequency are related to the frequency (f) as 2Pif
and f=1/T period of oscillating
