Answer:

0.266 m

Explanation:

Assuming the lump of patty is 3 Kg then applying the principal of conservation of linear momentum,

P= mv where p is momentum, m is mass and v is the speed of an object. In this case

where sunscripts p and b represent putty and block respectively, c is common velocity.

Substituting the given values then

3*8=v(15+3)

V=24/18=1.33 m/s

The resultant kinetic energy is transferred to spring hence we apply the law of conservation of energy

where k is spring constant and x is the compression of spring. Substituting the given values then

**Answer:**

F = K Q1 Q2 / R^2 = m g

Q1 = - Q2 = (4E12 * 1.60E-19) = 6.4E-7 coulombs

Q^2 = 4.10E-13

R^2 = 9.0E9 * 4.1E-13 / (.003 * 9.80) = 36.9E-4 / 2.94E-2

R^2 = .126

R = .35 m

Coal is formed from the remains of vegetations.

The sun's radiation is made up of rays of many different wavelengths.

When **comparing **the mutual inductance M12 of coil 1 with respect to coil 2 with the **mutual inductance **M21 of coil 2 with respect to coil 1, it turns out to option A: increases when they are brought **nearer**.

<h3>What is

**mutual inductance?**</h3>

Mutual Induction is known to be that which often takes place when a current is said to be passing via a coil or circuit and thus changes, the magnetic flux connected with a nearby coil or circuit will also be altered.

Since the emf will have to be in a state where it will be induced in the nearby coil or circuit. This phenomenon is known to be called ‘mutual induction’.

Hence, When **comparing **the mutual inductance M12 of coil 1 with respect to coil 2 with the **mutual inductance **M21 of coil 2 with respect to coil 1, it turns out to option A: increases when they are brought **nearer**.
