The pressure of the water on the diver is given in an expression written as:

<span>p=15+15/33d

where p is the pressure and d is the distance of the diver </span><span>below the surface.

The pressure is calculated as follows:

</span>p=15+15/33(100) = 15.00  pounds per square feet

Therefore, the correct answer is option A.

Answer:

CCCCCCCCCCC

Explanation:

The rate of change for the diver is

8.6 − 4.3

20 − 10

= 0.43. Therefore, the rate of change for the submarine is 4(0.43) = 1.72 and p = 1.72d

What would be the weight of the moon if it were resting on the surface of the earth
kari74 [83]
We need to be careful here.
The calculation of the gravitational force between two objects
refers to the distance between their centers. 
The minimum possible distance between the Earth's and moon's
centers is the sum of their radii (radiuses).

Earth's radius . . . . .  6,360 km  =  6.36 x 10⁶ meters
Moon's radius . . . . .  1,738 km  =  1.738 x 10⁶ meters
Sum of their radii  =                      8.098 x 10⁶ meters

Also:
Earth's mass . . . . .  5.972 x 10²⁴ kg
Moon's mass . . . . .  7.348 x 10²²  kg
<span>
and now we're ready to go !

       Gravitational force = 

                   G  M₁ M₂ / R²

= (6.67 x 10⁻¹¹ N-m²/kg²)(</span><span>5.972 x 10²⁴ kg)(7.348 x 10²²  kg)/</span>(8.098 x 10⁶ m)²

= (6.67 · 5.972 · 7.348 / 8.098²) · (10²³)      Newtons

=    (I get ...)        4.463 x 10²³ Newtons

That's almost exactly   10²³ pounds 

                           =  50,153,000,000,000,000,000 tons.     

Those are big numbers. 
All I can say is:  I wouldn't exactly call that "resting" on the surface".

The formation of condensation on a glass of ice water causes the ice to melt faster than it would otherwise. If 8.55 g of conden
SSSSS [86.1K]

Answer:

m = 62.14 g

Explanation:

Energy used to melt the ice is the energy released by the condensation of the water forms on the glass

so here we have

energy for the condensation of water is given as

let mass of water condensed = m

E = m_1 L_f

now the energy of vaporization is given as

E = m_2 L_v

here we know that

L_f = 79.8 kCal/kg

L_v = 580 k Cal/kg

Now we have

8.55 \times 580 = m \times 79.8

m = 62.14 g

⚠️⚠️A driver brakes to stop a car in 3.0 s. The car's momentum was 33,000
nlexa [21]

Answer: 11000 N

Explanation:

Given that,

Time required to stop car = 3.0 s

The car's momentum = 33,000

kg m/s

magnitude of force = ?

Recall that impulse is equal to the change in momentum of the car, hence

Impulse (I) = Momentum

(Since I = force x time, then

Force x time = momentum)

F x 3.0 s = 33,000 kg m/s

F = 33,000kg m/s / 3.0s

F = 11,000 N

Thus, 11000N of force was used to stop the car.
