Answer:
a) net force = 110N to the right.
b) acceleration = 5.5 m/s/s
Explanation:
a) 150N - 40N = 110N
b) F = ma
110N = 20kg x acceleration
acceleration = 110/20 = 5.5
You must know the masses of both objects and the gravitational constant used to calculate the gravitational force between the 2 objects.
Answer:
<u>So the correct answer is letter e)</u>
Explanation:
The electric field of an infinite yz-plane with a uniform surface charge density (σ) is given by:
Where ε₀ is the electric permitivity.
<u>As we see, this electric field does not depend on distance, so the correct answer is letter e)</u>
I hope it helps you!
Answer:
Explanation:
If one assume that each turn is like a strand of electromagnet, which can then be added up. Therefore, increase in the number of turns will yield to increase in the magnetic strength. Also if the current increases, then there will be increase in the magnetic field strength.
From Ohm's law
V = IR
I = V/R
That is a direct increase in voltage will lead to increase in current.
Increase the voltage of the battery and increases the number of turns of the coil. Will suit the situation
A, a spark because if you touch something after rubbing your hand on carpet or something you get a spark
