Your shadow follows you everywhere. How is it formed? Is it always the same size or shape? Do you always have one shadow?
Yanka [14]
Formed from an object blocking the light to a certain area.

Is not always the same size or shape, it varies depending on the position of the light.

You can have more than one shadow of you have more than one light source.

With what magnitude of force does a ball of mass 0.75 kilograms need to be hit so that it accelerates at the rate of 25 meters/s
SSSSS [86.1K]

Answer:

Assume that the ball undergoes motion along a straight line. ... F = m A Force = (mass) x (acceleration) The question tells you the mass and the acceleration. All YOU have to do is take the numbers and pluggum into Newton's 2nd law. F = m A = (0.75 kg) (25 m/s²) = (0.75 x 25) kg-m/s² = 18.75 Newtons .

A circular loop of flexible iron wire has an initial circumference of 167 cm, but its circumference is decreasing at a constant
Kisachek [45]

Answer:

Part a)

EMF = 5.6 \times 10^{-3} V

Part b)

Since the radius is decreasing so induced current will increase the flux through the coil

So it would be clockwise in direction

Explanation:

As we know that magnetic flux linked with the coil is given as

\phi = \pi r^2 B

now the rate of change in flux is given as

\frac{d\phi}{dt} = 2\pi r \frac{dr}{dt} B

now we know that circumference is decreasing at rate of 15 cm/s

so here we know the length of circumference as

C = 2\pi r

So rate of change in circumference is

\frac{dC}{dt} = 2\pi \frac{dr}{dt}

\frac{1}{2\pi}(15 cm) = \frac{dr}{dt}

final length of circumference at t = 8 s

C = 167 - (15)(8) = 47

Part a)

Now the induced EMF is given as

EMF = (2\pi r)(\frac{1}{2\pi})(0.15)(0.5)

EMF = (0.47)(\frac{1}{2\pi})(0.15)(0.5)

EMF = 5.6 \times 10^{-3} V

Part b)

Since the radius is decreasing so induced current will increase the flux through the coil

So it would be clockwise in direction
