Answer:
0.9 N
Explanation:
The electric force acting on a charge is given by:

where
q is the magnitude of the charge
E is the strength of the electric field
In this problem, we have
is the charge
is the strength of the electric field
Substituting into the equation, we find

Answer:if i know ill tell u
Explanation:
Isn't velocity Distance over time? if the degree isn't adding resistance it should be 4000 ÷ 20 which gives you 200mps ("per second") which is the velocity without resistance.
Answer:

Explanation:
First of all, we need to calculate the total energy supplied to the calorimeter.
We know that:
V = 3.6 V is the voltage applied
I = 2.6 A is the current
So, the power delivered is

Then, this power is delivered for a time of
t = 350 s
Therefore, the energy supplied is

Finally, the change in temperature of an object is related to the energy supplied by

where in this problem:
E = 3276 J is the energy supplied
C is the heat capacity of the object
is the change in temperature
Solving for C, we find:
