Answer:

  • So we have waves
  • F= 1/t
  • So F= 1/1.5= 0.66
  • V= wavelength × F
  • 8.0m/s= x × 0.66
  • x=12.2

A substance sample has a Mass of 45.0 g, and the Data Safety
marishachu [46]

The volume of the sample is 48.39 cm³.

<h3 /><h3>What is volume?</h3>

The term volume refers to the amount of three-dimensional space taken up by an item or a closed surface

To calculate the volume of the sample, we use the formula below

Formula:

  • D = m/v
  • v = m/D................ Equation 1

Where:

  • m = Mass of the smaple
  • D = Density of the sample
  • v = Volume of the sample.

From the question,

Given:

  • m = 45 g
  • D = 0.93 g/cm³

Substitute these values into equation 1

  • v = 45/0.93
  • v = 48.39 cm³

Hence, the volume of the sample is 48.39 cm³.

The gravity tractor, is a proposed spacecraft that will fly close to an asteroid whose trajectory threatens to impact the Earth.
Crazy boy [7]

Answer:

F_g=461lb_f

Explanation:

First calculate the mass of the asteroid. To do so, you need to find the volume and know the density of iron.

If r = d/2 = 645ft, then:

V = \frac{4}{3} \pi r^3

V = \frac{4}{3} \pi r^3\\V = 1.124\times10^{9}ft^3\delta_{iron}=m/V=491lb/ft^3m=V\times\delta=5.519\times10^{11}lb

In order to find force, use Newton's universal law of gravitation:

F_g=G\frac{m_1m_2}{d^2}

Where,

G= the gravitational constant:

G= 1.068846 \times10^{-9} ft^3 lb^{-1} s^{-2}

F_g=461lb_f

Which describes an object’s speed in free fall?
Mrac [35]
"Free fall" is the motion of an object when gravity is the ONLY force
acting on it.

In true 'free fall' the speed of an object increases at a constant rate
for the total duration of the fall.  The rate of increase, on or near the
Earth's surface, is 9.8 meters per second for each second of fall.

True free fall is almost impossible to observe in everyday life, because
whenever we see anything falling, it's almost always falling through air,
so gravity is NOT the only force acting on it.  The friction due to the
motion through air works against the gravitational force.  In many cases,
the result is that the object's speed eventually stops increasing and
becomes constant, at a speed often described with the faux technical,
high-fallutin' sounding phrase "terminal velocity".  It must be understood
that 'terminal velocity' is NOT a property of gravity or of free fall, but is
only a result of falling through some surrounding stuff that interferes with
the process of true 'free fall'.
