Answer:

The focal length of eyepiece is 3.68 cm.

Explanation:

Given that,

Distance = 19 cm

Focal length = 5.5 mm

Magnification = 200

Object distance = -25 cm

We need to calculate the focal length

Using formula of magnification

m=\dfrac{d}{f_{o}}+\dfrac{-25}{f_{0}f_{e}}

Put the value into the formula

f_{e}=\dfrac{19\times(-25)}{.55(-200-\dfrac{19}{.55})}

f_{e}=3.68\ cm

Hence, The focal length of eyepiece is 3.68 cm.

Rudik [331]

Answer:

τ= F r     into the blade

Explanation:

The moment of a force is defined by

         τ = F x r

where the bold indicates vectors

Let us write in the expression in magnitude

         τ = F r sin θ

in our case the force is tangent to the wheel therefore the angle between F and the radius is 90º, and the sin 90 = 1

       τ= F r

The direction of τ can be used by the rule of the right hand, the fingers curve in the direction of the torque when advancing from the force to the radius and the thumb points in the direction of the torque.

In this case, for a clockwise rotation, the fingers are curved in the direction and the thumb points into the blade, this is the direction of the τ.

A car traveling at 60 mph has how much more energy than a car going at 20 mph? How many times does the kinetic energy of a car i
irinina [24]

K.E. increases by 9 times

Explanation:

The kinetic energy of a car is given by:

KE=\frac{1}{2}mv^2

where

m is the mass of the car

v is its speed

From this definition, we see that the kinetic energy depends on the square of the velocity. Assuming that both cars have same mass, m, the kinetic energy of the first car is:

K_1 = \frac{1}{2}m(60)^2

while the kinetic energy of the second car is

K_2 = \frac{1}{2}m(20)^2

if we calculate the ratio, we get

\frac{K_1}{K_2}=\frac{(60)^2}{(20)^2}=3^2 =9
