Answer:

During the past century in the United States, advances in public health and health care have increased life expectancy by approximately 30 years and led to dramatic changes in the leading causes of death. As chronic diseases became the leading causes of illness and death in the United States by the middle of the 20th century public health researchers began to shift their focus to identifying their complex and interrelated causes.

A cheetah can go from a state of resting to running at 20 m/s in just two seconds what is the cheetah's average acceleration?

Sunny_sXe [5.5K]

It's C i believe. To solve it we just take 20 and divide it by 2. Which gives us the average of 10 m/s

The A string of a violin is a little too tightly stretched. Beats at 4.00 per second are heard when the string is sounded togeth

Basile [38]

Answer:

$T=2.5*10^{-3}s$

Explanation:

From the question we are told that:

Beat frequency $F_b=4$

Frequency $F=400Hz$

Generally the equation for Frequency of the violin is mathematically given by

$f_v=F_b+F$

$f_v=4+400Hz$

$f_v=404Hz$

Therefore the period of the violin string oscillations is

$T=\frac{1}{f_v}$

$T=\frac{1}{404}$

$T=2.5*10^{-3}s$

An athlete stretches a spring an extra 40.0 cm beyond its initial length. How much energy has he transferred to the spring, if t

notsponge [240]

Answer:

Explanation:

Step one:

given data

extension= 40cm

Spring constant K= 52.9N/cm

Step two:

Required

the Kinetic Energy KE

the expression to find the kinetic energy is

KE= 1/2ke^2

substituting our data we have

KE= 1/2*52.9*40^2

KE=0.5*52.9*1600

KE= 42320Joules

<u>The answer is b) 4230 J </u>

A body of mass 2 kg at O has an initial velocity of 3m/s along OE and it is subjected to a force of 4N perpendicular to OE the d

timofeeve [1]

Perpendicular acceleration:
F = ma
a = 4 / 2 = 2 m/s²

Perpendicular distance:

s = ut + 1/2 at²
s = 0 x 4 + 1/2 x 2 x 4²
s = 16 m

Horizontal distance:
s = ut
= 3 x 4
= 12 m

Total distance = √(12² + 16²)
= 20 m.

Conductivity in a metal results from the metal atoms having

maks197457 [2]

Answer: A) highly mobile electrons in the valence shell

Explanation: conductivity in metals is a result of the movement of electrically charged particles—the electrons. These free electrons also known as valence electrons are free to move, and as a result they can travel through the lattice that forms the physical structure of a metal. The presence of valence electrons determines a metal's conductivity. However, several other factors can affect the conductivity of a metal such as impurities, temperature, magnetic fields etc.
