Answer:
at R/
Explanation:
The free-fall acceleration at the surface of Earth is given by
where
G is the gravitational constant
M is the Earth's mass
R is the Earth's radius
The formula can be rewritten as
(1)
We want to shrink the Earth at a radius R' such that the acceleration of gravity becomes 3 times the present value, so
g' = 3g
Keeping the mass constant, M, and substituting into the equation, we have
Three of these are strong electrolytes:
- HCl (Hydrochloric acid)
- HNO3 (Nitric acid)
- NaOH (Sodium hydroxide)
Two of these are Weak electrolytes:
- HF (Hydrogen fluoride)
- HC2H3O2 (Acetic acid)
And the other two are Non-electrolytes:
- C6H12O6 (Glucose)
- C2H5OH (Ethanol)
Answer:
c. It refers to any government program that tends to reduce fluctuations in GDP automatically.
Explanation:
Automatic Stabilizer is nothing but any scheme or program that that tends to reduce fluctuations in GDP automatically. It is generally intended to stabilize the GDP of a nation.
For examples In cases of economic slow down, the government sells its ownership in public sectors undertakings like, railways, oil and natural gases, to private players. So, that government has some money to combat the slowdown.
Answer:
c. Clockwise
Explanation:
As per FARADAY's the rate of change in magnetic flux linked with a coil will induce EMF in the coil and this will result the induce current in the coil.
Here we know that the direction of induced current in the closed loop is in such a way that the magnetic flux due to induced current always oppose the flux due to which it is induced
So we can say that if the flux linked with the coil will increase with time then flux of induced current will be in opposite direction to oppose the increasing flux.
So here when magnetic field becomes stronger then the induced current is in such a way that will always oppose the increasing flux of magnetic field
So we will say that correct answer will be
c. Clockwise
The answer is B tell me if I am wrong.
