What is one way to increase the amplitude if a wave in a medium?

Olivia is on a swing at the playground at which point is her kinetic energy increasing and her potential energy decreasing

Nimfa-mama [501]

Whenever an object is falling, its potential energy
is decreasing and its kinetic energy is increasing.

Olivia's potential energy is decreasing and her kinetic energy
is increasing as she moves toward the right side of the picture,
all the way from W, through X, to the bottom of the arc.

Two dogs fight over a bone. The larger of the two pulls on the bone to the right with a force of 42 N. The smaller one pulls to

tamaranim1 [39]

Answer:

Explanation:

A

35 N Small Dog <=======BONE=========> Bigger Dog 42 N

B

Fnet = Large Dog - small dog The forces are subtracted because they are acting in opposite Directions.

Fnet = 42 - 35

Fnet = 7 N

C

m = 2.5 kg

F = 7 N

a = ?

F = m * a

7 = 2.5 a

a = 7 / 2.5

a = 2.8 m/s^2

Why should a physical quantity be measured?

Natasha_Volkova [10]

Answer:

It allows us to understand nature much more deeply than does qualitative description alone.

Explanation:

Without explaining the measurements, a quantity cannot always be measured.

A sample of ore containing radioactive strontium 38Sr90 has an activity of 8.2 × 105 Bq. The atomic mass of strontium is 89.908

ahrayia [7]

From the activity values and the decay constant, the mass of of Strontium in the sample is:

$1.62 × 10^{-7}g$

<h3>What is the decay constant of an element?</h3>

The decay constant of an element is the probability of decay of a nucleus per unit time.

{λ = ln 2 / t1/2

where;

t1/2 is the half-life of the isotope.

The half-life is converted to seconds since the decay constant is asked in per seconds.

$28.8 years = 28.8 × 3.156 × 10^{7} = 908928000 s \\$

Hence;

$λ = \frac{ln2}{90892800s} = 7.626 s^{-1}$

The activity of the element, A, the decay constant, λ and the number of nuclei, N are related as follows:

A = (–) λN

$N = \frac{8.25 ×10^{5}}{7.626×10^{-10}} = 1.082 × 10^{15}$

Molar mass of Strontium-90 is 90 g.

1 mole of Strontium-90 contains 6.02×10^23 nuclei.

The mass, m of Strontium in the sample is calculated:

$m = 1.082 × 10^{15} × \frac{90 g}{6.02 × 10^{23}} = 1.62 × 10^{-7}g \\$

Therefore, the mass of of Strontium in the sample is:

$1.62 × 10^{-7} \: g$
