Osmium, is the densest metal found,has density of 22.6 g/cm 3. The mass of the block is 113 g. Find its volume. (1 mark for formula and 1 mark for showing calculation)

Answers

Answer 1

Answer:

Volume = 5 cm³

Explanation:

Given the following data;

Density = 22.6 g/cm³

Mass = 113 grams

To find the volume;

Density can be defined as mass all over the volume of an object.

Simply stated, density is mass per unit volume of an object.

Mathematically, density is given by the equation;

[tex]Density = \frac{mass}{volume}[/tex]

Making volume the subject of formula, we have;

[tex]Volume = \frac{mass}{density}[/tex]

Substituting into the equation, we have:

[tex]Volume = \frac{113}{22.6}[/tex]

Volume = 5 cm³

A certain AM radio wave has a frequency of 1.12 x 106 Hz. Given that radio waves travel at 2.99 x 108 m/s, what is the wavelength of this radio wave? (Round your answer to three significant figures.) Answer in "m" units

Answers

Answer:

2.67×10² m

Explanation:

Applying

V = λf............... Equation 1

Where V = Velocity of radio wave, λ = wave length, f = frequency.

make λ the subject of the equation

λ = V/f................ Equation 2

From the question,

Given: V = 2.99×10⁸ m/s, f = 1.12×10⁶ Hz.

Substitute these values into equation 2

λ = (2.99×10⁸)/(1.12×10⁶)

λ = 2.66696×10² m

λ ≈ 2.67×10² m

attached to a battery. The voltage drop
across the 120 Ohm resistor is 6.00 V.
What is the voltage drop across the
180 Ohm resistor?
(Hint: How much current is flowing?)
(Unit = V)

Answers

Answer:

I=0.05 Amper

v=9 volts

Explanation:

I=V/R1

l=6/120=0.05Amper

voltage of 180ohm =IR2=0.05×180=9volts

I=0.05 Amper
V=9 volts

Answers

Answer:

At infinity the image is formed

When a lens produces light rays that are parallel, the image is: C. non-existent.

A ray diagram can be defined as the graphical representation of the possible paths light takes from one point (source) to another.

Hence, a ray diagram is a graphical representation of how light interacts with a boundary, so as to help us view a point on the image of an object.

Basically, the characteristics of an image produced from a lens or mirror can be determined by drawing a ray diagram of the possible paths taken by light.

On a ray diagram, an image produced from a lens is non-existent when the lens produces light rays that are parallel because the refracted rays of light neither diverge nor converge.

In conclusion, an image cannot be formed (non-existent) when a lens produces light rays that are parallel, due to refraction.

7. Can the speed of a particle be negative? Can the
velocity of a particle be negative? Give arguments to
support your answers.

Answers

Answer:

Suppose at time t1 = zero and v1 = 50 MPH

                    time t2 = 10 sec and v2 = 10 MPH

Change in speed   =  (v2 - v1) / (t2 - t1) = (10 - 50) MPH / (10 - 0) sec

Change in speed = -40 MPH / 10 sec = - 4 MPH / sec

If you specify the velocity as always East then

change in velocity = - 4 MPH East

Had the particle finished by moving in the Westerly direction  then

Change in velocity = (-10 - 50) MPH / 10 sec = -60 / 10 MPH = -60 MPH East

Where West was the positive direction

Initially v1 was 50 East and v2 was -10 East with a difference of 60 MPH

Which nucleus completes the following equation?

Answers

Option D. ⁸⁵₃₆Kr

Explanation:

⁸⁵₃₅Br —> ⁰₋₁e + ?

Let ⁿₘZ represent the unknown.

Thus, the equation becomes:

⁸⁵₃₅Br —> ⁰₋₁e + ⁿₘZ

Next, we shall determine n, m and Z as follow:

85 = 0 + n

85 = n

Thus,

n = 85

35 = –1 + m

Collect like terms

35 + 1 = m

36 = m

Thus,

m = 36

ⁿₘZ => ⁸⁵₃₆Z = > ⁸⁵₃₆Kr

Thus, the equation:

⁸⁵₃₅Br —> ⁰₋₁e + ⁿₘZ

Becomes:

⁸⁵₃₅Br —> ⁰₋₁e + ⁸⁵₃₆Kr
