timama [110]

The answer should be 11,460 because the first half-life leaves 50 percent left and the next half-life would leave 25 percent which dates the bones at 11,460 years old.

A 24.0 cm long screwdriver is used as a lever to open a can of paint. If the fulcrum is 0.500 cm away from the end of the screwd

ELEN [110]

The ideal mechanical advantage of the screwdriver is 47

Explanation:

In this problem, the screwdriver acts as a lever.

The Ideal Mechanical Advantage (IMA) of a lever is given by:

$IMA=\frac{d_i}{d_o}$

where:

$d_i$ is the distance of the point of application of the input force from the fulcrum

$d_o$ is the distance of the output force from the fulcrum

In this problem, we have:

$d_o = 0.500 cm$ , since the fulcrum is 0.500 cm from the end

$d_i = 24.0 cm - 0.500 cm = 23.5 cm$ (the distance between the fulcrum and the point where are we holding the screwdriver)

Substutiting,

$IMA=\frac{23.50 cm}{0.50 cm}=47$

1. A beam of charged particles enters a magnetic field and travels in a helical or spiral path What does the shape of the path i

Makovka662 [10]

B. The initial velocity has components both parallel and perpendicular to the magnetic field.

Explanation:

When a charged particle moves in a magnetic field, it experiences a force which is given by

$F=qvB sin \theta$

where

q is the charge

v is the velocity of the particle

B is the strength of the magnetic field

$\theta$ is the angle between the directions of v and B

From this formula, it is clear that the force has only a component in the direction perpendicular to direction of the the motion of the particle. Therefore:

if the initial velocity is perpendicular to the magnetic field, then the particle will follow a perfectly circular path
If the initial velocity is parallel to the magnetic field, then the particle will continue moving straight, since it will experience no force
If the initial velocity has components both parallel and perpendicular to the magnetic field, then it will move in a helical or spiral path, which is a composition of the two motions above (straight motion + circular motion)
