The magnetic flux through a loop:
dexar [7]

Answer:

The magnetic flux through a loop is zero when the B field is perpendicular to the plane of the loop.

Explanation:

Magnetic flux are also known as the magnetic line of force surrounding a bar magnetic in a magnetic field.

It is expressed mathematically as

Φ = B A cos(θ) where

Φ is the magnetic flux

B is the magnetic field strength

A is the area

θ is the angle that the magnetic field make with the plane of the loop

If B is acting perpendicular to the plane of the loop, this means that θ = 90°

Magnetic flux Φ = BA cos90°

Since cos90° = 0

Φ = BA ×0

Φ = 0

This shows that the magnetic flux is zero when the magnetic field strength B is perpendicular to the plane of the loop.

Decide whether each statement describes mass or weight.
vova2212 [387]

<u>Mass</u>

  • Mass is measured in kilograms.
  • Mass does not change when gravity changes.
  • Mass is the amount of matter in something.

<u>Weight</u>

  • Before I answer, we have to know weight formula. Weight = mass × acceleration due to gravity.
  • Therefore, weight is measured in Newtons.
  • Weight changes when gravity changes. This is because weight is dependent on acceleration due to gravity.
  • Weight is a gravitational force.

Hope you could understand.

If you have any query, feel free to ask.

Fantom [35]

Answer:

b. Increasing the mass of the arrow.

Explanation:

The formula is K=1/2mv^2. Increasing the mass also increases the kinetic energy.

two pendulums of lengths 100cm and 110.25cm start oscillating in phase. after how many oscillations will they again be in same p
goldfiish [28.3K]

Angular frequency of pendulum is given by

\omega = \sqrt{\frac{g}{l}}

for both pendulum we have

\omega_1 = \sqrt{\frac{9.81}{1.00}}

\omega_1 = 3.13 rad/s

For other pendulum

\omega_2 = \sqrt{\frac{9.81}{1.1025}}

\omega_2 = 2.98 rad/s

now we have relate angular frequency given as

[tex\omega_1 - \omega_2 = 3.13 - 2.98 = 0.15 rad/s[/tex]

now time taken to become in phase again is given as

t = \frac{2\pi}{\omega_1 - \omega_2}

t = \frac{2\pi}{0.15} = 41.88 s

now number of oscillations complete in above time

N = \frac{t}{\frac{2\pi}{\omega_1}}

N = \frac{41.88}{\frac{2\pi}{3.13}}

N = 21 oscillation
