Answer:
You're answer should be series circuits are simpler than parallel circuits.
Explanation: I found this answer on the internet.
In series circuit, all the components are connected in single path of current flow.
If one part of the circuit breaks, complete circuit would break and all the other parts also would not operate.
The voltage is not same everywhere. It is different across each component.
In series circuit, net resistance is more as resistance of all the components connected in series are added up.
Answer:
26.82m/s
Explanation:
Given
Mass = m= 0.4kg
Initial Velocity = u = 0
Charge = 4.0E-5C
Distance= d = 0.5m
Object Charge = 2E-4C
First, we'll calculate the initial energy (E)
E = Potential Energy
PE = kQq / d
Where k = coulomb constant = 8.99E9Nm²/C²
Energy is then calculated by;
PE = 8.99E9 * 4E-5 * 2E-4 / 0.5
PE = 143.84J
Energy = Potential Energy = Kinetic Energy
K.E = ½mv² = 143.84J
½mv² = ½ * 0.40 * v² = 143.85
0.2v² = 143.85
v² = 143.85/0.2
v² = 719.25
v = √719.25
v = 26.81883666380777
v = 26.82m/s
Hence, the object is 26.82m/s fast when the cart moving is very far (infinity) from the fixed charge
Answer:
h= 43.07 m
Explanation:
<u>Given:</u>
Vi = 15 m/s, Vf= 0m/s, t = 2s, a=g=9.8 m/s²
<u>To Find:</u>
height of the clip h= ?m
<u>Solution:</u>
Since it is thrown horizontally an angle of 0°, so Viy = Viy sin 0° = 0 m/s
and Vix = Vix cos 0° = 15 m/s
<u>For Horizontal </u>
h = 0 m, ax = 0m/s and Vix = 15 m/s
so h = h₀ + Vix t + 1/2 a t²
⇒ h₀ = 30 m (Horizontal distance)
<u>For vertical</u>
Viy = 0m/s, h= ? m, a =g=9.8 m/s²
h = h₀ + Viy t + 1/2 a t²
h = 30m + 0 + 1/2 (9.8 m/s² × 2²)
h = 30 + 16.07
h= 43.07 m
Answer: Solid
Explanation: Most of the outer part of our planet is solid. This solid mantle sits on an outer liquid core and a solid inner core.
