An object is 2.0 cm from a double convex lens with a focal length of 1.5 cm. Calculate the image distance
Tomtit [17]

Answer:

0.857 cm

Explanation:

We are given that:

The focal length for a convex lens to be (f) = 1.5cm

The object distance (u) = - 2.0 cm

We are to determine the image distance (v) = ??? cm

By applying the lens formula:

\dfrac{1}{f} = \dfrac{1}{u}+\dfrac{1}{v}

By rearrangement and making (v) the subject of the above formula:

v = \dfrac{uf}{u-f}

replacing the given values:

v = \dfrac{(-2.0)(1.5)}{(-2.0 -1.5)}

v = \dfrac{-3.0}{(-3.5)}

v = 0.857 cm

Which statement correctly describes the formation of electric current?
Semenov [28]

Answer:

b. A voltage causes electric charges to move from lower to a higher potential.

Explanation:

As we know, current flows from high voltage to low voltage and the electric charge flows opposite to the direction of the current. That is why we can say that the electric charge flows from low voltage to high voltage.

Resistance does not cause the electron to flow from low voltage to high voltage.

Therefore the answer is b.

Light in vacuum is incident on the surface of a glass slab. In the vacuum the beam makes an angle of 38.0° with the normal to th
iren [92.7K]

Answer:

n_glass = 1.404

Explanation:

In order to calculate the index of refraction of the light you use the Snell's law, which is given by the following formula:

n_1sin\theta_1=n_2sin\theta_2         (1)

n1: index of refraction of vacuum = 1.00

θ1: angle of the incident light respect to normal of the surface = 38.0°

n2: index of refraction of glass = ?

θ2: angle of the refracted light in the glass respect to normal = 26.0°

You solve the equation (1) for n2 and replace the values of all parameters:

n_2=n_1\frac{sin\theta_1}{sin\theta_2}=(1.00)\frac{sin(38.0\°)}{sin(26.0\°)}\\\\n_2=1.404

The index of refraction of the glass is 1.404

Nicki rides her bike at a constant speed for 6 km. That part of her ride takes her 1 h. She then rides her bike at a constant sp
Savatey [412]

km x h = km/h

First trial: 6 x 1 = 6km/h

Second trial: 9 x 2 = 18km/h

6 + 18 = <u>24km/h</u> (Total)

Or

6 + 9 = 15 km

2 + 1 = 3h

15 + 3 = 18

15 x 2 = 30

3 x 2 = 6

30 - 6 = <u>24km/h</u>
