A material will float on the surface of a liquid if the material has a density less than that of the liquid. given that the dens

ity of water is approximately 1.0 g/ml, will a block of material having a volume of 1.3 104 in3 and weighing 350 lb float or sink when placed in a reservoir of water?

We will first convert lb to grams and in³ to milliliters. 
350 lb : 2.205 = 158.75733 kg = 158,757.33 grams
1.3 · 10^4 in³ = 13,000 in³ = 13,000 · 0.016387064 = 213.031 liters 
213.031 liters · 1,000 = 213,031 milliliters
Density = m / V = 158,753.33 g / 213,031 ml = 0.7452 g/ ml
Answer: A block of material will float.

Zielflug [23.3K]

I'm not sure who plait is, but here's the problem with this plan that's so obvious most people miss it:

With one asteroid hurtling toward Earth, you have the possibility of one large body slamming into the Earth in one place.

Now, say we're able to successfully launch, guide, and detonate a big explosive weapon very close to the asteroid ... make it pull up alongside the asteroid, go BOOM, and shatter the asteroid into a thousand pieces.

THEN what do you have ?

You have a THOUSAND pieces, some of them quite large, with their center of mass still following the same trajectory that the original asteroid was.  NOW there's a big fat chance that SEVERAL of these shattered pieces will hit the Earth ... maybe in a hundred DIFFERENT places.  

NOW we're worse off than we were before the Orange One's Space Force decided that a nuclear weapon would be the answer to our looming problem.

A feather is dropped onto the surface of the moon. How far will the feather have fallen if it reaches in 9.00 seconds? Given: g
Hitman42 [59]
The distance traveled while accelerating from rest is

                           D  =  1/2 a t²    .

For this problem, we shall totally ignore air resistance.
We do so completely without any reservation or guilt,
because we know that there is no air on the moon.

                     D  =  (1/2) · (1.6 m/s²) · (9 sec)²

                         =       (0.8 m/s²) · (81 s²)

                         =        (0.8 · 81) m

                         =            64.8 meters  .

(That's about 213 feet !  The astronaut must have dropped the feather
from his spacecraft while he was aloft ... either just before touchdown
or just after liftoff.)

vagabundo [1.1K]

Answer:

50kPa and if the area decreases, the pressure increases

Explanation:

P=F/A; P=pressure, F=force, A=area

85000N/1.7 m^2 = 50000 N/m^2; Pa = Pascal = N/m^2

=50 kPa

A cyclist is traveling 10 m/s with an acceleration of 6 m/s2. How fast is the cyclist traveling at the end of 20 seconds
krok68 [10]

Answer:

<em>The cyclist is traveling at 130 m/s</em>

Explanation:

<u>Constant Acceleration Motion </u>

It's a type of motion in which the velocity of an object changes by an equal amount in every equal period of time.

Being a the constant acceleration, vo the initial speed, vf the final speed, and t the time, the following relation applies:

v_f=v_o+at

The cyclist initially travels at 10 /s and it's accelerating at a=6m/s^2. We need to know the new speed when t= 20 seconds have passed.

Apply the above equation:

v_f=10+6\cdot 20

v_f=10+120

v_f=130\ m/s

The cyclist is traveling at 130 m/s
