Answer:
k = 39.2 N / m
Explanation:
The 200 g block is accelerated by the force of friction between the blocks. Let's use Newton's second law
N- W = 0
N = W
fr = ma
μ N = ma
μ mg = ma
a=μ g
Let's look for the acceleration of the largest block that has oscillatory movement
x = A cos (w t)
A = 0.05 m
The maximum acceleration is cos wt = ±1
a = A w2
a = A k / m
We substitute and calculate
μ g = A k / M
k = μ g M / A
The mass that performs the oscillation is the mass of the two bodies
M = m1 + m2
k = 0.2 9.8 (0.800+ 0.200) /0.05
k = 39.2 N / m
The ratio of the number of turns in the primary and the secondary coil of a step-up transformer is 1 : 200.
The formula for calculating the secondary voltage in a transformer is: N = V = Where No and N are the primary and secondary coils' respective turn counts; V and V are the RMS voltages across the primary and secondary coils, and I and Is are the primary and secondary currents.
Calculation: Due to this:
The coil's N2 to Ns turn ratio is 1/20.
We understand that N=1/20 = 4/LP: Is = 20:1.
The transformer uses the following principles: A wire's magnetic field moves as a result of a changing current flowing through it. A wire exposed to a moving magnetic field will create a changing current.One of the coils produces a magnetic field that grows and contracts in response to the changing voltage of the AC when an AC source is connected to it.
In other words, the coil generates a growing magnetic field as the voltage across it rises. The magnetic field generated around the capacitor increases when the voltage reaches its maximum and starts to decline.

Answer: Newtons second law of motion: the acceleration of an object is directly related to the net force and inversely related to its mass. ... So, the force/mass ratio (from the equation acceleration = force/mass) is the same for each. Therefore, the acceleration is the same and they reach the ground at the same time.
