Answer:

Current increases

Resistance remains same

Explanation:

As you change the value of the battery voltage

We know that the current is dependent on the supply of power , so the current increases but the resistance remains same.

Two point sources are vibrating in phase producing two-dimensional water wave interference. The first antinodal line on either s

Viktor [21]

For all antinodal positions we know that

$\Delta \phi = 2N\pi$

now we also know the relation between phase difference and path difference

$\Delta \phi = \frac{2\pi}{\lambda}\Delta x$

now we will have

$2N\pi = \frac{2\pi}{\lambda}\Delta x$

now from above equation we will have

$\Delta x = N\lambda$

now for the first anti node position

N = 1

$\Delta x = \lambda$

A baseball was hit and reached its maximum height in 3.00s. Find (a) its initial velocity; (b) the height it reaches.[29.4 m/s;

kicyunya [14]

Answer:

u= 29.43 m/s

h=44.14 m

Explanation:

Given that

t= 3 s

We know that acceleration due to gravity ,g = 9.81 m/s² (Downward)

Initial velocity = u

Final velocity ,v= 0 (At maximum height)

We know v = u +a t

v=final velocity

u=initial velocity

a=Acceleration

Now by putting the values in the above equation

0 = u - 9.81 x 3

u= 29.43 m/s

The maximum height h is given as

v² = u ² - 2 g h

0² = 29.43 ² - 2 x 9.81 x h

$h=\dfrac{29.43^2}{2\times 9.81}\ m$

h=44.14 m

A proton enters a uniform magnetic field of strength 1 T at 300 m/s. The magnetic field is oriented perpendicular to the proton’

scZoUnD [109]

A charged particle moving in a magnetic field experiences a force equal to:

$\vec{F}=q\vec{v}\times \vec{B}$

Thus, the magnitude of the force that the proton experiences is given by:

$F=qvBsin\theta$

The magnetic field is perpendicular to the proton's velocity, therefore, we have $\theta=90^\circ$ . Replacing the given values, we obtain:

$F=1.6*10^{-19}C(300\frac{m}{s})(1T)sin(90^\circ)\\F=4.8*10^{-17}N$
