Answer:

C) Acceleration is directly proportional to net force divided by mass.

Explanation:

As per Newton's 2nd law we know that net force on the object is product of mass and acceleration of the object

so we will have

F = ma

so here we can say that the force and mass of the object is directly depends on each other and the equation is just product of mass and acceleration.

So in order to find the acceleration we have

a = \frac{F}{m}

so we will have

C) Acceleration is directly proportional to net force divided by mass.

A 19.0-kg cart is moving with a velocity of 7.20 m/s down a level hallway. A constant force of -13.0 N acts on the cart and its
gulaghasi [49]

Answer:

a. -369.36J

b. -123.9J

c. 9.52m

Explanation:

From the expression for kinetic energy

K. E=1/2mv^2

Since the mass is constant, but the velocity changes. Hence the change in kinetic energy is

K.E=1/2*19(3.6²-7.2²)

K.E= -369.36J

b. to determine the workdone by the force,we determine the distance moved.

But the acceleration is from

F=ma ,

a=f/m

a=-13/19

0.68m/s²

the distance moved is

s=v²/2a

s=3.6²/2*0.68

s=9.52m

Hence the work done is

W=force * distance

W=-13*9.52

W=-123.9J

d. the distance moved is

s=v²/2a

s=3.6²/2*0.68

s=9.52m

A person standing a certain distance from four identical loudspeakers is hearing a sound level intensity of 125 dB. What sound l
DENIUS [597]

Answer:

\mathbf{\beta = 123.75 \ dB}

Explanation:

From the question, using the expression:

125 \ dB = 10 \ log (\dfrac{I}{I_o})

where;

I_o = 10^{-12} \ W/m^2

I = 10^{12.5} \times 10^{-12} \ W/m^2

I = 3.162 \ W/m^2

This is a combined intensity of 4 speakers.

Thus, the intensity of 3 speakers = \dfrac{3.162\times 3}{4}

= 2.372 W/m²

Thus;

\beta = 10 \  log ( \dfrac{2.372}{10^{-12}} ) \ W/m^2

\mathbf{\beta = 123.75 \ dB}

Think back to coulomb's law. two coins with identical charges are placed on a lab table 1.35 m apart.
ziro4ka [17]

The Coulomb’s law is expressed mathematically as:

F = k * q1 * q2 / d^2

Where,

F = force of attraction between 2 particles = 2.0 N

<span> k = Coulomb’s constant = 8.988 * 10^9 N m^2 / C^2</span>

q = charge of the particle

d = distance between the 2 particles = 1.35 m

 

Since the two coins have identical charges therefore q1 = q2 =q

F = k* q^2 / d^2

2.0 N = (8.988 * 10^9 N m^2 / C^2) * q^2 / (1.35 m)^2

q = 2.01 * 10^-5 C

<span>Therefore each coins have charges equivalent to 2.01 * 10^-5 C.</span>
