Answer:
a. 0.25
Explanation:
The toy is moving across the floor at constant velocity - this means that its acceleration is zero.
According to Newton's second law, this means that the net force acting on the toy is zero:
(1)
because a=0.
The net force, in this case, consists of two forces acting in opposite directions:
- The applied force, F = 2.0 N
- The frictional force,
where is the coefficient of sliding friction and (mg)=8.0 N is the weight of the toy.
Therefore, the equation of the forces (1) becomes:
Answer:
1327 kg
Explanation:
So the net force exerted on the wagon would be the sum of forces from 2 horses subtracted by friction force
This force results in an acceleration of a = 1.3 m/s2. We can use Newton's 2nd law to calculate the mass of the wagon
The new natural frequency would be ω/2.
we know that,
= ω. -> equation 1
now, when capacitance is quadrupled,
. -> equation 2
substituting value of equation 1 in equation 2 , we get,
Hence, the new natural frequency of the circuit is ω/2.
what do you mean by frequency ?
The resonant frequency for a particular circuit is the frequency at which this equality stands true. Where L is the inductance in henries and C is the capacitance in farads, this is the LC circuit's resonant frequency.

Answer:
Force = 125 [N]
Explanation:
In the attached image we can see a sketch of the lever system.
And if we make a sum of moments at the point O equal to zero (0).
In the equation showed in the image, we can determinate the force that we need
