Answer:

<em>C. Inverted, real, and larger</em>

Explanation:

Inverted - An inverted image is formed when the rays intersect below the principal axis. An inverted image points downward.

Real - A real image can be projected on a screen. A real image is on the opposite side of lens as compared to the object. Whereas, for a mirror, a real image forms on the same side as the object.

Image size - a general measure of the image as compared to the original object. Image size is typically stated as smaller than the object, the same size as the object, or larger than the object.

Answer:

inverted, real, and larger

Explanation:

To form the image of the object placed at the 5cm mark, the ray diagram must be properly drawn as described.

1. The first incident ray coming from the object strike the lens and parallel to the principal axis will converge at the other side of the lens and pass through the focus after refraction.

2. The second incident ray must pass through the optical center of the lens undeflected.

The refracted ray in (1) and the incident ray in (2) will intersect at a point where the image will then be formed.

The nature of the image that wikk be formed will be inverted, real and larger than the object as shown in the attachment.

Note that inverted images are real images.

A rolling ball has 3,276) of energy, what is it's mass when it is rolling at a velocity of 53m/s? what is the mass​
hram777 [196]

Initial velocity U = 0

Final velocity V = 32.23 m/s

Explanation:

Given that a coin is dropped from the top of the Tower of Pisa, 53m above the ground.

What is the coin's initial velocity ?

Since the coin is dropped from the tower, the initial velocity U will be equal to zero.

Therefore, U = 0

But the final velocity V will be calculated by using the formula

V^2 = U^2 + 2gH

V^2 = 0 + 2 × 9.8 × 53

V^2 = 1038.8

V = sqrt ( 1038.8)

V = 32.23 m/s

A student is preparing to take a bath when she realizes the hot water tap in the bathroom is not working the student go to the k
WITCHER [35]

Answer:

The final temperature of the bath water will be 55°C

Explanation:

A student is preparing to take a bath when she realizes that the hot water tap is not working.

The student goes to the kitchen and prepares 10 L of 100 degree Celsius water to mix with 10 L of 10 degree Celsius water. What will be the final temperature of the bath water?

Using the relation, Heat lost  = Heat gained (assuming no heat is lost to the surroundings).

Heat lost by hot water = heat gained by cold water

Using the formula of heat, Q = mcΔT

where m = mass of water, c = specific heat capacity of water, ΔT = temperature difference

mass of water = density * volume (density of water = 1 kg/L)

mass of hot water, m₁ = 1 kg/L * 10 L = 10 kg;

mass of cold water, m₂ = 1 kg/L * 10 L = 10 kg;

specific heat capacity of water, c = 4200 j/kg

Let the final temperature of the mixture be T

-m₁cΔT₁ = m₂cΔT₂ ( since heat is lost by the hot water)

-m₁ΔT₁ = m₂ΔT₂

-10 * (T- 100) = 10 * (T - 10)

-10T + 1000 = 10T - 100

20T = 1100

T = 1100/20

T = 55°C

Therefore, the final temperature of the bath water will be 55°C

What is the maximum wavelength of incident light that can produce photoelectrons from silver? The work function for silver is Φ=
zalisa [80]

Answer:

4.24nm

0.385eV

Explanation:

Maximum wavelength (λmax) :

λmax = ( hc) /Φ

h = plancks constant = 6.63 * 10^-34

c = speed of light = 3*10^8

1ev = 1.6 * 10^-19

Φ = 2.93eV = 2.93* (1.6*10^-19) = 4.688*10^-19

λmax = [(6.63 * 10^-34) * (3 * 10^8)] / 4.688*10^-19

λmax = 19.89 * 10^-26 / 4.688*10^-19

λmax = 4.242 * 10^-7 m

λmax= 4.24nm

B.)

E = hc / eλ eV

λ = 3.75nm = 3.75 * 10^-7m = 375 *10^-9

E = (6.63 * 10^-34) * (3 * 10^8) / (1.6 * 10^-19) * (375 * 10^-9)

E = 19.89 * 10^-26 / 600 * 10^-28

E = 0.03315 * 10^-26 + 28

E = 0.03315 * 10^2

E = 3.315 eV

Stopping potential : (3.315 eV - 2.93eV) = 0.385eV
