1) 2.17 s

The period of a mass-spring oscillating system is given by

$T=2 \pi \sqrt{\frac{m}{k}}$

where k is the spring constant and m is the mass attached to the spring. In this problem, we have

k = 25.1 N/m

m = 3.0 kg

Substituting into the equation, we find

$T=2 \pi \sqrt{\frac{3.0 kg}{25.1 N/m}}=2.17 s$

2) 0.46 Hz

The frequency of the oscillating system is equal to the reciprocal of the period:

$f=\frac{1}{T}$

Therefore, by substituting T=2.17 s, we find:

$f=\frac{1}{T}=\frac{1}{2.17 s}=0.46 Hz$

3) 0.13 s

As before, the period of a mass-spring oscillating system is given by

$T=2 \pi \sqrt{\frac{m}{k}}$

where k is the spring constant and m is the mass attached to the spring. In this part of the problem, we have

k = 25.1 N/m

m = 11 g = 0.011 kg

Substituting into the equation, we find

$T=2 \pi \sqrt{\frac{0.011 kg}{25.1 N/m}}=0.13 s$

4) 7.69 Hz

The frequency of the oscillating system is equal to the reciprocal of the period:

$f=\frac{1}{T}$

Therefore, by substituting T=0.13 s, we find:

$f=\frac{1}{T}=\frac{1}{0.13 s}=7.69 Hz$

5) 1.59 s

Again, the formula for the period of a mass-spring oscillating system is given by

$T=2 \pi \sqrt{\frac{m}{k}}$

In this part of the problem, we have

k = 25.1 N/m

m = 1.6 kg

Substituting into the equation, we find

$T=2 \pi \sqrt{\frac{1.6 kg}{25.1 N/m}}=1.59 s$

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper.

Answer from: Quest

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm. the wire diameter is d = 0.9 mm. the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2) in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
