A +0.0129 C charge feels a 4110 N

Physics
1 answer:
Otrada [13]3 years ago
6 0

Answer:

r = 14.13 m

Explanation:

Given that,

Charge 1 = +0.0129 C

Charge 2 = -0.00707 C

The force between charges, F = 4110 N

We need to find the distance between charges. Let the distance be r. The force between two charges is given by :

F=\dfrac{kq_1q_2}{r^2}\\\\4110=\dfrac{9\times 10^9\times 0.0129\times 0.00707}{r^2}\\\\r=\sqrt{\dfrac{9\times 10^9\times 0.0129\times 0.00707}{4110}} \\\\r=14.13\ m

So, the distance between charges is equal to 14.13 m.

g100num [7]

Based on Einstein's theory of gravity, if the sun and its mass were to suddenly disappear, earth would stay in its current orbit for a few minutes before taking off into space.

<h3>What would occur to our world if the sun were to suddenly vanish?</h3>

The Earth would be drawn to a new center of gravity if the sun disappeared. Earth's gravity would change, as would that of the rest of the solar system, and Earth would begin to drift into space since there would no longer be a steady source of energy from the sun. It is a foolish dream to think that life could exist without the sun forever. Humans could be able to survive for a while in some sort of base, such as a nuclear-powered dome.

The good news is that there wouldn't be many living things for the radioactive waste to endanger; however, there also probably wouldn't be any liquid water to cool the power system. All photosynthetic species, including plants and algae, would die if just the sun's light persisted.

The blade of a lawn mower is rotating at an angular speed of 128 rad/s. The tangential speed of the outer edge of the blade is 3
stiv31 [10]

Answer:

0.25m

Explanation:

Using the expression that relates the angular velocity(w) and the linear velocity (v).

v= wr where;

w is the angular speed= 128rad/s

v is the linear speed = 32m/s

r is the radius

r = v/w

r = 32/128

r = 0.25m

The radius of the blade is 0.25m

Consider a stone in free fall on a planet with gravitational acceleration 3.4 m/s^2. Suppose you would like the stone to experie
Stella [2.4K]

Answer:

Angle of incline is 20.2978°

Explanation:

Given that;

Gravitational acceleration on a planet a = 3.4 m/s²

Gravitational acceleration on Earth g = 9.8 m/s²

Angle of incline = ∅

Mass of the stone = m

Force on the stone along the incline will be;

F = mgSin∅

F = ma

The stone has the same acceleration as that of the gravitational acceleration on the planet.

so

ma = mgSin∅

a = gSin∅

Sin∅ = a / g

we substitute

Sin∅ = (3.4 m/s²) / (9.8 m/s²)

Sin∅ = 0.3469

∅ = Sin⁻¹( 0.3469 )

∅ = 20.2978°

Therefore, Angle of incline is 20.2978°
