CuF2 is the Answer if it’s wrong let me know
a).
-- There were 10.00 mL of water in the graduated cylinder originally.
-- After the marble was added to the cylinder and sank, the total volume
of water and marble in the cylinder was 11.20 mL.
-- The extra 1.20 mL that suddenly showed up was the volume of the marble.
-- We can use 1 mL = 1 cm³ .
-- The volume of the marble was <em>1.20 cm³ </em>.
b).
Density = (mass) / (volume)
For the marble . . .
Density = (3.05 g) / (1.20 cm³) = <em>2.54 gm/cm³</em> (rounded)
Answer:
The strength of gravity on Pluto is 0.6 m/s²
Explanation:
The given mass of the shoe = 0.5 kg
The weight of the shoe (on Pluto), W = 0.3 N
Therefore, given that weight, W = Mass × The acceleration due to gravity, We have;
The strength of gravity = The force gravity applies to each unit of mass = The acceleration due to gravity (in m/s²)
The weight of the shoe, W = The mass of the shoe × The strength of gravity on Pluto
Substituting the known values, gives;
0.3 = 0.5 × The strength of gravity on Pluto
∴ The strength of gravity on Pluto = 0.6 m/s².
Answer:
23.38 years
Explanation:
Speed of Allison = 0.83 c = v
Time passed according to Allison = Δt = 29.5 years
Time dilation
For Nora 52.88 years would have passed
So, their age difference would be 52.88-29.5 = 23.38 years
The smallest marble has the most kinetic energy therefore it would be the correct answer
