Answer:

Isobars are similar to height lines on a geographical map, and they are drawn so that they can never cross each other. Meteorologists use isobars on weather maps to depict atmospheric pressure changes over an area and to make predictions concerning wind flow.

Consider a particle with unit charge q, and mass m, in a constant magnetic field B directed along the positive z–axis. The parti

max2010maxim [7]

Answer:

it must be helical motion in which the charge particle will move uniformly along z axis and simultaneously it will move in circular path in xy plane.

Explanation:

Magnetic field is along z axis while velocity is in x-z plane

so we will have

$F = q(\vec v \times \vec B)$

so here we can say

$F = q(u\hat i + w\hat k) \times (B \hat k)$

so we will have

$F = quB(-\hat j)$

so here the net force on the charge is perpendicular to its x directional velocity along - Y direction

So due to this component of motion it will move along a circle while other component of the motion will remain uniform always

So here it is combination of two parts

1) Uniform circular motion

2) Uniform motion

So we can say that it must be helical motion in which the charge particle will move uniformly along z axis and simultaneously it will move in circular path in xy plane.

If the total momentum for a system is the same before and after the collision, we say that momentum is conserved. If momentum we

andrew-mc [135]

Answer:

Ratio = 1:1

Explanation:

$P_{i}$ = initial momentum of the system

$P_{f}$ = final momentum of the system

For the momentum to be conserved , final total momentum must be equal to initial total momentum, so we have

$P_{f} = P_{i}$

Dividing both side by $P_{i}$ , we get

$\frac{P_{f}}{P_{i}} = \frac{P_{i}}{P_{i}} \\\frac{P_{f}}{P_{i}} = 1\\$

hence

Ratio = 1

A child jumps on a trampoline. What causes the child to rise in the air

Veseljchak [2.6K]

The trampoline is loaded with multiple springs that counteract the gravitational forces of the mass of the child. If the Forces of the springs are bigger than the gravitational force of the child, the child will rise in the air.
