Labels that belong in the marked ares X, Y & Z include;

X: Curves outward

Y: Image may be smaller than object

Z: Image is always virtual

Since the rays never meet, the images formed by convex mirrors are always virtual and smaller than the object, and since they are smaller, the images appear to be further than they actually are.

When beryllium-7 ions (m = 11.65 × 10-27 kg) pass through a mass spectrometer, a uniform magnetic field of 0.205 T curves their

AysviL [449]

Answer:

ratio =0.3075 T

Explanation:

The magnetic field B creates a force on a moving charge such that

$F = qvB$

Now this causes a centripetal acceleration

$F = = mv^2/r$

$qvB = mv^2/r$ ...........(i)

$B = mv/(rq)$ ...............(ii)

If accelerating potential V is same and then kinetic energy equals the potential energy difference

$\frac{1}{2} mv^2 = Vq$

$v = \sqrt{(2Vq/m)}$ put these value in equation (ii)

$B = m\frac{\sqrt{(2Vq/m)} }{rq}$

simplifying we get

$B =m \frac{(\sqrt{ 2Vm/q})}{r}$

for same location r will be same in both case

$B_{7} = \frac{ \sqrt{(m_{7})(2V/q) }}{r}$ ..............(iii)

$B_{10} = \frac{ \sqrt{(m_{10})(2V/q) }}{r}$ ..........(iv)

dividing (iv) and (iii) equation we get

$\frac{B_{10}}{B_{7}} = \sqrt{\frac{m_{10}}{{m_7}} }$

${B_{10}} = B_{7} \sqrt{\frac{m_{10}}{{m_7}} }$

$B_{10} = 0.2574T\sqrt{\frac{ (1.663x10^-26}{(1.165x10^-26)}$

so on solving we get

=0.3075 T

Why there's a rainbow after the rain?

Diano4ka-milaya [45]

Answer:

Rainbow is formed due to dispersion of sunlight by tiny water droplets suspended in the atmosphere after a rain shower .....After rain shower the sun is visible to us again and the rain water droplets are suspended in the atmosphere therefore they disappear sunlight and and rainbow is formed....

What has more inertia, bowling ball and tennis ball

Leona [35]

-- Inertia varies exactly as mass . . . more mass = more inertia.

-- If both objects are on the same planet, then
the heavier one is the one that has more mass.

-- So the bowling ball has more inertia than the tennis ball.
