The work function for silver is 4.73 eV. (a) Convert the value of the work function from electron volts to joules.

pogonyaev

Answer:

$W=7.56\times 10^{-19}\ J$

Explanation:

Given that,

The work function for silver is 4.73 eV.

We need to find the value of the work function from electron volts to joules.

We know that,

$1\ eV=1.6\times 10^{-19}\ J$

For 4.73 eV,

$4.73\ eV=1.6\times 10^{-19}\times 4.73\\\\=7.56\times 10^{-19}\ J$

So, the work function for silver is $7.56\times 10^{-19}\ J$ .

Lily took 6 hours to complete a journey at an average speed of 58 km/h. For the first 4 hours, she travelled at an average speed

arlik [135]

Answer:

92km

Explanation:

Given parameters:

Duration of the journey = 6hrs

Average speed = 58km/hr

Now, let us find the total distance of the journey;

Distance = Speed x time

Distance = 58 x 6 = 348km

So;

Average speed for the first 4hrs = 64km/hr

Time = 4hrs

Distance = 64 x 4 = 256km

For the rest of the journey, the student will cover;

= 348km - 256km

= 92km

If a 3-kg rock is thrown at a speed of 2 m/s in a gravity-free environment (presuming one could be found), then an unbalanced fo

Katarina [22]

Answer:

a. False

Explanation:

For an object to be moving at a constant velocity, a net force of 0 N would be required.

Newton's 1st Law of Motion states that an object will remain at rest unless acted upon by an unbalanced force, and an object will remain in motion unless acted upon by an unbalanced force.

Therefore, the unbalanced force of 6 N would not allow the rock to maintain its constant speed.

The answer to this question is A) False.

Radiation from the Sun reaching Earth (just outside the atmosphere) has an intensity of 1.4 kW/m2. (a) Assuming that Earth (and

baherus [9]

To solve the problem we will require the concept of Force as a definition of pressure and Area, and the concept of light pressure itself determined by the relationship between intensity and the speed at which light travels. We will match the terms and find the desired force value,

$F = PA$

Here,

P = Pressure

A = Area

Pressure due to the light of the sun will be

$P= \frac{I}{c}$

Here,

I = Intensity

c = Speed velocity

Equation both therms we have that

$F = \frac{IA}{c}$

We have a circular area then

$F = \frac{I(\pi r^2)}{c}$

Replacing with our values (Adding the radius of the Earth)

$F = \frac{(1.4*10^3W/m^2)(\pi (6.32*10^6m)^2)}{3.0*10^8m/s}$

$F = 6.0*10^8N$

Therefore the Force on Earth due to radiation pressure is $6*10^8N$

Why does a pencil in a glass container filled with water appear to be bent?

Bogdan [553]

The phenomenon is called "refraction". It's the process of
light waves bending toward a different direction when they
cross a boundary between different media ... in this case,
from water into air.

Your brain doesn't know that the light waves bent toward a
new direction when they came out of the water into the air,
so your brain locates the bottom half of the pencil just like it
ALWAYS does ... in the direction the light waves are coming FROM.
