Newton's second law is the hardest to describe as it is about momentum (F = ma), and a lot of people don't know the concept of momentum.

Newton's first law of motion:- every object moves in a straight line unless acted upon by a force.

Newton's 2nd law of motion:-the acceleration of an object is directly proportional to the net force exerted and inversely proportional to the item's mass. Newton's 2nd law is a quantitative description of the changes that a force can produce on the motion of a body. It states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it.

Newton's 3rd law of motion:- For every action, there's an equal and opposite reaction.

Christian made some pancakes she's so 3/5 of them in the morning and 1/4 of the remainder in the afternoon is she had 300 pancak

DiKsa [7]

Christian made 1000 pancakes.

Explanation:

Let us represent the total amount of Pancake made by Christian as = K

From the problem;

Christian ate $\frac{3}{5}$ of the pancake in the morning = $\frac{3}{5}$ * K = $\frac{3}{5}$ K

We know that Christian cannot eat her pancake and at the same time have it, the remaining pancake will then be:

total amount of cake - fraction eaten

Remainder = K - $\frac{3}{5}$ K= $\frac{2}{5}$ K

In the afternoon, we know that she ate 1/4 of the remaining cake:

$\frac{1}{5}$ K* $\frac{2}{5}$ K = $\frac{1}{10}$ K

The remaining cake in the afternoon will be:

Total amount of cake remaining from morning - amount eaten in the afternoon

= $\frac{2}{5}$ K - $\frac{1}{10}$ K

= $\frac{3}{10}$ K

The fraction of the cake remaining in the afternoon is $\frac{3}{10}$ K

Since she had 300cakes left in the afternoon, then :

$\frac{3}{10}$ K= 300

K = 1000 pancakes

Therefore Christian made 1000 pancakes.

Two spherical conductors are separated by a distance much larger than either of their radii. Sphere A has a radius of 11.5 cm an

bonufazy [111]

Explanation:

As the given spheres are connected by a thin wire so, the potential on the spheres are the same.

$\frac{q_{1}}{r_{1}} = \frac{q_{2}}{r_{2}}$ ......... (1)

Hence, total charge will be as follows.

$q_{1} + q_{2}$ = Q = -95.5 nC .......... (2)

Using the above two equations, the final equation will be as follows.

$q_{2} = \frac{Qr_{2}}{r_{1} + r_{2}}$

and, $q_{1} = \frac{Qr_{1}}{r_{1} + r_{2}}$

Hence, we will calculate the charge on sphere B after the equilibrium is reached as follows.

$q_{2} = \frac{Qr_{2}}{r_{1} + r_{2}}$

= $\frac{-95.5 \times 74.4 cm}{(11.5 + 74.4) cm}$

= 82.714 nC

Thus, we can conclude that the charge on sphere B after equilibrium has been reached is 82.714 nC.
