How many arcseconds are in 1°? B) 360 A) 60 C) 3,600 D) 100 E) 10,000
jenyasd209 [6]

Answer:

C) 3,600

Explanation:

An arcsecond is equal to 1/3600 of a degree. Hence, the inverse will give the number of arcsecond in a degree. An arcsecond is one of the ways to measure angular measurement

1\ arcminute=\frac{1}{60}\ degree\\\Rightarrow 1\ degree=60\ arcminute

\\\Rightarrow 1\ degree=60\times 60\ arcsecond\\\Rightarrow 1\degree=3600\ arcsecond

The small piston of a hydraulic lift, has an area of 0.01m2. If a force of 250N is applied to the small piston if it has an area
postnew [5]

Answer:

Explanation:

Given that,

Small piston Hydraulic piston has an area

A1 = 0.01m²

If the force applied is 250N is applied to the small piston at an area of 0.05 m²

Then,

F2 = 250 N and A2 = 0.05m²

Then, applying pascal principle,

Pressure at small area = pressure are bigger area

P1 = P2

F1 / A1 = F2 / A2

F1 / 0.01 = 250 / 0.05

F1 / 0.01 = 5000

Cross multiply

F1 = 5000 × 0.01

F1 = 50 N

Changing subscripts is one of the steps of balancing a chemical equation
Sergeeva-Olga [200]

<u>Answer:</u>

No, Changing subscripts is not the step of balancing a chemical equation

<u>Explanation:</u>

In balancing a chemical equation you have to keep one thing in mind that the no of atoms and elements on both sides such as reactant (before reaction) and product( after a reaction) must be equal. Coefficients are added to equal the no of atoms and elements, but we will not change the subscript.
