0.318 cm. What is the ideal mechanical advantage?
vodomira [7]

The ideal mechanical advantage will be 8.017. The ideal mechanical advantage value may be grater than the actual value of mechanical advantage.

<h3>What is mechanical advantage ?</h3>

Mechanical advantage is a measure of the ratio of output force to input force in a system, it is used to obtained efficiency of  forces in levers and pulley.

The ideal mechanical advantage is found as;

\rm IMA = \frac{d \pi}{l} \\\\ \rm IMA = \frac{0.812 \times  \pi}{0.318} \\\\ IMA=8.017

The ideal mechanical advantage will be 8.017.

A laser shines violet light with a frequency of 703 thz onto the metal with a threshold frequency of 295 thz, what is the kineti
hram777 [196]

The kinetic energy of the ejected electrons will be 2782.5 ×10⁻²² eV.

<h3>What is threshold frequency?</h3>

The threshold frequency of incoming radiation is the lowest frequency at which photoelectric emission or electron emission is impossible.

The threshold frequency is the light frequency that causes an electron to dislodge and emit from the metal's surface.

From the photoelectric effect, the equation obtained as;

\rm  hv=hv_0+KE\\\\ KE=h(v-v_0)\\\\ KE=6.625 \times 10^{-34}(702-282)Hz \\\\ KE= 6.625 \times 10^{-34}\times 420 \times 10^{12} \ Hz \\\\ KE=2782 .5 \times 10^{-22} \ eV

Hence,the kinetic energy of the ejected electrons will be 2782.5 ×10⁻²² eV.

Two coils have the same number of circular turns and carry the same current. Each rotates in a magnetic field acting perpendicul
ANEK [815]

Answer:

4.14 cm.

Explanation:

Given,

For Coil 1

radius of coil, r₁ = 5.6 cm

Magnetic field, B₁ = 0.24 T

For Coil 2

radius of coil, r₂ = ?

Magnetic field, B₂ = 0.44 T

Using formula of maximum torque

\tau_{max}= NIAB

Since both the coil experience same maximum torques

now,

NIA_1B_1 = NIA_2B_2

A_1B_1 = A_2B_2

r_1^2 B_1 = r_2^2 B_2

5.6^2\times 0.24= r_2^2\times 0.44

r_2 = 4.14\ cm

Radius of the coil 2 is equal to 4.14 cm.

How much work w is done by the electrostatic force on the moving point charge?
V125BC [204]

As we know that electrostatic force is a conservative force

so we can say by the condition of conservative force

F_c = -\frac{dU}{dr}

here we can rearrange the above equation as

dU = - F_c.dr

now integrate both sides

\int dU = - \int F_c . dr

Now we know by the definition of work done by a force is given by

W = \int F.dr

now work done by conservative force is given as

W_c = \int F_c . dr

Now from above work done by electric field to move charge from one point to other is given as

W_{EF} = \int F_{e}.dr = - \int dU

so here work done is given as

W_{EF} = U_i - U_f

so change in potential energy is given by work done
