I think it’s the third option but I’m not entirely sure
Which has the highest electronegativity value?
A
hydrogen
B
calcium
C
helium
D
fluorine d because fluorine has a higher group number
The question is incomplete, complete question is:
A fluid occupying
of volume has a mass of 4 Mg. Calculate its density and specific volume in SI, EE, and BG units.
Explanation:
1) Mass of liquid = m = 4 Mg = 4 × 1,000 kg = 4,000 kg
(1 Mg = 1000 kg)
Volume of the fluid = V = 
Density of the fluid = D

Specific volume is the reciprocal of the density :

Specific volume of the fluid = 

2)
Density of the fluid in English Engineering units = D 
1 kg = 2.20462 lb
1 m = 3.280 ft

Specific volume of the fluid :

3)
Density of the fluid in British Gravitational System units = D 
1 kg = 0.06852 slug
1 m = 3.280 ft

Specific volume of the fluid :

A heterogeneous mixture since you can separate the ingredients that make it up.
The correct answer is - 1 cm/yr.
Alongside the western coast of South America, the Nazca plate and the South American plate are in a collision for several million years now, with the Nazca plate being the one that is subducting in this convergent plate boundary.
If the Nazca plate's focus has moved 1,000 km in the last 10 million years, than in order to get to the annual movement of the subduction we need to convert the km into cm first:
1 km = 10,000 cm
1,000 x 10,000 = 10,000,000
1,000 km = 10,000,000 cm
Than we need to divide the number of cm with the number of years:
10,000,000 / 10,000,000 = 1
And we get the result of 1 cm/yr.
