Answer:

<u>Toxicity is a quantitative property</u>

Explanation:

  • Qualitative property of a object cannot be measured it can just be observed
  • Quantitative property of a substance  can be measured and be assigned a numerical value .
  • <u>The toxicity level of a substance can be measured and be assigned a numeral value </u>

A bicyclist is traveling 10 m/s at 30 degrees
AysviL [449]

Explanation:

The momentum is defined as the product between the mass and velocity:

p = m·v

Let's calculate his total momentum:

ptot = 70kg · 10m/s = 700 kg·m/s

Now we know that he's traveling 30 degrees south-east.

The momentum along the y axis will be:

py = p·cos30° = 606 kg·m/s

Along the x-axis:

px = psin30° = 350 kg·m/s

Consider a father pushing a child on a playground merry-go-round. The system has a moment of inertia of 84.4 kg · m². The father
natulia [17]

Answer:

Part a)

KE = 101.4 J

Part b)

N = 0.043 revolution

Part c)

F = 2.7 N

Explanation:

Part a)

As we know that the rotational kinetic energy of the merry go round is given as

KE = \frac{1}{2}I\omega^2

KE = \frac{1}{2}84.4(\omega^2)

here we know that

\omega = 2\pi(\frac{14.8}{60})

\omega = 1.55 rad/s

Now we have

KE = \frac{1}{2}(84.4)(1.55^2)

KE = 101.4 J

Part b)

Now we know that work done due to torque = change in kinetic energy

W = KE_f - KE_i

\tau (2N\pi) = 101.4 - 0

375(2\pi N) = 101.4

N = 0.043 revolution

Part c)

In order to stop it in four revolutions we have

\tau(2\pi N) = \Delta KE

FR(2\pi N) = 101.4

F(1.5)(2\pi \times 4) = 101.4

F = 2.7 N

Take the following measured gauge (or gage) pressures and convert them to absolute pressures in both kPa and psi units for an am
mamaluj [8]

Answer:

Explanation:

Given

ambient Pressure =98.10 kPa

(a)gauge pressure 152 kPa

we know

Absolute pressure=gauge pressure+Vacuum  Pressure

P_{abs}=152+98.10=250.1 kPa or 36.27 psi

(b)P_{gauge}=67.5 Torr or 8.99 kpa

as 1 Torr is 0.133 kPa

P_{abs}=8.99+98.10=107.09 kPa or 15.53 psi

(c)P_{vaccum}=0.1 bar or 10 kPa

Thus absolute pressure=98.10-10=88.10 kPa or 12.77 psi

as 1 kPa is equal to 0.145 psi

(d)P_{vaccum}=0.84 atm  or 85.113 kPa

as 1 atm is equal to 101.325 kPa

P_{abs}=98.10-85.11=12.99 kPa or 1.88 psi
