The force required is
(15 kg) x (the acceleration, in m/s²) newtons.
All these resistors are in series so we can take the sum of them by:
Rtotal = R1 + R2 + R3......
So...
Rtotal = 2 + 3 + 4 + 6
Rtotal = 15
So now the total resistance in the circuit is 15 ohms and the potential difference applied to the circuit is 45 volts
Now we can use:
V = IR
Isolate for I
V/R = I
45/15 = I
I = 3 amps (A)
If the object is at equalibirium, then the force is balanced. '<em>Balanced</em>' is the key word that is used to describe equilibrium situations. If the object has a zero net force, the acceleration is 0 m/s/s. Objects at equilibrium should have an acceleration of 0 m/s/s.
<h2>
Answer:1.636</h2>
Explanation:
Let be the mass of sled and children before impact.
Let be the mass of sled,children and their father.
Let be the velocity before impact.
Let be the velocity after impact.
The momentum can be conserved because there are no external forces that can affect the momentum.
This is a inelastic collision.
Given,
So,
Answer:
14.36 N
Explanation:
= Tension in string 1
= Tension in string 2
= mass of the bar = 2.7 kg
= weight of the bar
weight of the bar is given as
N
= mass of the bar = 1.35 kg
