Explanation:

Acceleration and the other term are the same physical phenomenon - just with opposite affects. Acceleration increases velocity, while the other term that begins with the letter "R" reduces.

***(Brainly's language filter is blocking the use of the second term in my answer.)***

Acceleration is defined as the rate of change of the velocity of an object per unit of time...

$a = \frac{dv}{dt}$

Acceleration would be a POSITIVE (+) quantity, while the r-word would be negative (-).

A woman stands on a bathroom scale in a motionless elevator. When the elevator begins to move, the scale briefly reads only 0.64

Galina-37 [17]

Answer:

The downwards acceleration is 3.53 m/s2.

Explanation:

Let the true weight is m g.

The reading of the balance, R = 0.64 mg

Let the acceleration is a.

As the apparent weight is less than the true weight so the elevator goes down wards with some acceleration.

Use Newton's second law

m g - R = m a

m g - 0.64 m g = m a

0.36 g = a

a = 3.53 m/s2

Two charged spheres on a frictionless horizontal surface are attached to opposite ends of a string & are in static equilibri

deff fn [24]

Answer:

the red sphere has a charge of 9.899 10⁻⁶ C and

the green sphere 0.101 10⁻⁶ C

Explanation:

For this exercise we will use coulomb's law

F = k q₁ q₂ / r²

where they indicate the value of the force F = 2.5 N, the distance between them r = 0.06 m

they also indicate the value of the total load

q₁ + q₂ = 10 10⁻⁶ C

we substitute the values

2.5 = 9 10⁹ q₁ q₂ / 0.06²

2.5 0.06 2/9 10⁹ = q₁ q₂

1 10⁻¹² = q₁ q₂

10 10⁻⁶= q₁ + q₂

we have two equations with two i unknowns, so the system can be solved.

q₁ = 1 10⁻¹² / q₂

we substitute in the other equation

10 10⁻⁶ = 10⁻¹² / q₂ + q₂

let's solve the equation

10 10⁻⁶ q₂ = 10⁻¹² + q₂²

q₂² - 10⁻⁵ q₂ + 10⁻¹² = 0

q₂ = [10⁻⁵ ± √(10⁻¹⁰ - 4 10⁻¹²)] / 2

q₂ = [10⁻⁵ + - 0.9798 10⁻⁵] / 2 = 10⁻⁵ (1 + - 0.9798) / 2

q₂ = 0.9899 10⁻⁵ C

q₂ = 0.0101 10⁻⁵ C

let's find the charge of the other sphere

q₂ = 0.9899 10⁻⁵ C

q₁ = 10⁻⁵ - q₂

q₁ = 10⁻⁵ - 0.9899 10⁻⁵

q₁ = 0.0101 10⁻⁵ C

therefore the red sphere has a charge of 9.899 10⁻⁶ C and

the green sphere 0.101 10⁻⁶ C
