True because all switches use contacts to start or stop the flow of electrons in a circuit
Answer:
Explanation:
We can use kinematics equation .
What we're given:
- of 100.0 m/s
- of 12 s
- of -8.0
Solving for :
Answer:
The direction should be in the positive x direction.
Explanation:
Given that
Electric filed E= 410 V/m (In Negative y direction)
V= 9.1 x 10 ⁵ m/s
As we know that
F= E q + q.V x B
Given that protons is moving constant speed so ,F=0
F= E q +q. V x B
0= E + V x B
E = -V x B
- 410 j = - ( 9.1 x 10 ⁵ k x B i)
The direction should be in the positive x direction.
If I'm correct if you pluck the center of the string creating a pulse off both directions and would be reflected off the ends of the string my calculations would be 10.37sec
Answer:
1J
Explanation:
Work done = force × distance
1 × 1 = 1
Work done = 1J
J = Joules
