The volume is 4cm³.

  • The mass of a substance per unit of volume is its density. Density is most frequently represented by the symbol ρ.
  • The density is 250g/cm³.
  • Mass is a physical body's total amount of matter. Inertia, or the body's resistance to acceleration when a net force is applied, is also measured by this term. The strength of an object's gravitational pull on other bodies is also influenced by its mass. The kilogramme serves as the SI's fundamental mass unit.
  • The mass is 1000g.
  • density = mass/volume
  • Volume is a measurement of three-dimensional space that is occupied. It is frequently expressed mathematically using imperial or SI-derived units.
  • volume = mass/density
  • volume = 1000/250
  • volume = 4cm³

A 0.425 kg can of beans sits on a
Delicious77 [7]

Answer:

9.38J

Explanation:

mass = 0.425kg

height (h) = 2.25m

g = 9.81m/s^2

Gravitational potential energy (PE) = mgh

Plug in all info you got:

(0.425kg)(9.81m/s^2)(2.25m) = 9.38J

Deimos's Orbit. Deimos orbits Mars at a distance of 23,460 km from the center of the planet and has a period of 1.263 days. Assu
mihalych1998 [28]

Answer:

M = 5.882 10²³ kg

Explanation:

Let's use Newton's second law to analyze the satellite orbit around Mars.

         F = m a

force is universal attraction and acceleration is centripetal

          a = v²/ R

the modulus of velocity in a circular orbit is constant

         v= d/T

the distance of the cicule is

        d =2pi R

       a = 2pi R/T  

we substitute

          - G m M / R² = m ( - \frac{4\pi^2 R^2  }{T^2 R})

         G M = \frac{ 4\pi ^2 R^3  }{T^2 }

         M = \frac{4 \pi ^2 R^3 }{ G T^2 }

the distance R is the distance from the center of the planet Mars to the center of the satellite Deimos

         R = 23460 km = 2.3460 10⁷ m

the period of the orbit is

         T = 1,263 days = 1,263 day (24 h / 1 day) (3600s / h)

          T = 1.0912 10⁵ s

let's calculate

          M = \frac{4 \pi ^2  ( 2.3460 \ 10^7)^3 }{5.67 10^{-11} \ (1.0912 \ 10^5)^2 }

          M = 509.73418 10²¹  /8.66640 10⁻¹

          M = 58.817 10²² kg

          M = 5.882 10²³ kg

An object is propelled along a straight-line path by a force. If the net force were doubled, the object's acceleration would be_
nikdorinn [45]

Answer:

double

Explanation:

According to the newton's second law

force = mass x acceleration

So, acceleration is directly proportional to the force.

As the force is doubles, the acceleration is also doubled.
