Answer:
B) The current of the entire circuit is lowered.
Explanation:
There are two ways in which a resistor can be connected in a circuit;
i) Series: In a series connection, resistors are connected end to end. In this arrangement, the current passing through each resistor is the same while the potential difference across each resistor is different.
ii) Parallel: In a parallel connection, resistors are connected to common junctions. In this arrangement, the potential difference across each resistor is the same while the current across each resistor varies.
In a series circuit, the effective resistance is the algebraic sum of resistance of all the resistors connected in series. Hence, if a large resistor is connected in series, the effective resistance of the circuit is greatly increased.
Since the voltage is given by;
V=IR (Ohm's law)
Where R is the effective resistance
Then;
I = V/R
If R becomes very large due to a large resistance connected in series, then the current of the entire circuit is lowered.

Explanation:
Muons in the atmosphere, a component of cosmic rays. Atmospheric muons are an essential component of cosmic ray showers. When a high energy primary particle coming from space collides with a nucleus of the upper atmosphere, it generates a spray of particles which later interact in their turn.
Answer:
14000 J / 0.40 J/s = 35 000 s or about 9.75 hrs
Answer:
The Sun produces energy by the process of nuclear fusion. Nuclear fusion occurs when lighter nuclei combine to produce a larger, heavier nucleus. In the process, energy is released. Nuclear fusion requires very high temperatures and pressures. Nuclear fusion occurs in the core of the Sun when hydrogen atoms combine to form helium atoms.

Answer:
The percentage of the weight supported by the front wheel is A= 19.82 %
Explanation:
From the question we are told that
The center of gravity of the plane to its nose is 
The distance of the front wheel of the plane to its nose is 
The distance of the main wheel of the plane to its nose is 
At equilibrium the Torque about the nose of the airplane is mathematically represented as

Where m is the mass of the airplane
is the weight of the airplane supported by the main wheel
So

Substituting values
Now the weight supported at the frontal wheel is mathematically evaluated as

Substituting values
Now the weight of the airplane is = mg
Thus percentage of this weight supported by the front wheel is
19.82 %
