Compare an contrast a cell to a human body

Answer:

398.3 m, 334.2 m

Explanation:

The magnitude of the displacement vector is

v = 520 m

And its direction is

measured as north of east.

The x-component of this vector is given by:

While the y-component is given by

Final answer:

The x-component of the displacement vector (east-west direction) is approximately 398 m and the y-component (north-south direction) is approximately 334 m.

Explanation:

Displacement vectors contain both magnitude and direction information. In the case of a displacement vector 520 m long, pointing 40 degrees North of East, we can break it down into x and y components using trigonometric functions, specifically cosine and sine.

For the x-component (east-west direction), we can use the cosine function because it gives us the adjacent side in a right triangle, which is the east-west direction in our case. Therefore, the x-component will be:
520 m * cos(40) = 398m (rounded to nearest unit).

For the y-component (north-south direction), we can use the sine function because it gives us the opposite side in a right triangle, which is the north-south direction in our case. Hence the y-component will be:
520 m * sin(40) = 334 m (rounded to nearest unit).

To apply the same force as the person, the brother have to sit at a distance of 5 m.

What is meant by torque ?

Torque is defined as the rotational analogue of force. It is the cross product of force and the displacement of the object.

Here,

Mass of the person, m₁ = 50 kg

Mass of the brother, m₂ = 20 kg

Distance of the person, d₁ = 2 m

For the see-saw to get balanced, the torque applied by the two persons each side must be equal.

τ₁ = τ₂

where τ₁ is the torque applied by the person and τ₂ is that applied by the brother.

So, F₁d₁ = F₂d₂

m₁g x d₁ = m₂g x d₂

m₁d₁ = m₂d₂

Therefore, distance of the brother,

d₂ = m₁d₁/m₂

d₂ = 50 x 2/20

d₂ = 5 m

Hence,

To apply the same force as the person, the brother have to sit at a distance of 5 m.

Answer:

5

Explanation:

The first law of thermodynamics is a version of the law of conservation of energy, adapted for thermodynamic systems. The law of conservation of energy states that the total energy of an isolated system is constant; energy can be transformed from one form to another, but can be neither created nor destroyed.

In layman's term: like charges don't attract while opposite charges doelectrostatic forces between point A( which is charged) and point B (which is also charged) are proportional to the charge of point A and point B. there is also something else about this  law that I don't quite remember.

___________________________________________________

Here is the formula:

F = k x Q1 x Q2/d^2

What the formula means:

F=force between charges

Q1 and Q2= amount of charge

d=distance between these two charges

k= Coulombs constant (proportionally constant)
