Suppose that a charged particle of diameter 1.00 micrometer moves with constant speed in an electric field of magnitude 1.00×105

Gnesinka [82]

Answer:

Q1 = 7.25*10^(-16) C

Explanation:

We are given;

electric field strength = (1 x 10^5 N/C

drag force (F) = 7.25 x 10^(-11) N

The question says it's moving with constant velocity. This means that he particle is in equilibrium and not accelerating.

Columbs law force of attraction or repulsion between two charges is given as;

F=(KQ1Q2)/r²

Now, electric field strength is given as the formula;(K*Q2)/r², thus plugging the relevant values gives us;

7.25 x 10^(-11) N= (1 x 10^(5) N/C)Q1 Q1 = 7.25 x 10^(-11) /(1 x 10^(5))

Q1 = 7.25*10^(-16) C

Which of the following is NOT true of all the inner planets?

Artist 52 [7]

Hi there! :)

$\large\boxed{\text{B. They are called gas giants.}}$

In the solar system, we can categorize the planets as such:

Inner planets: Mercury, Venus, Earth, Mars

Outer planets: Jupiter, Saturn, Uranus, Neptune

The Inner planets are the only planets that consist of solid rock. They also do not have rings and have impact craters due to their early formation.

In comparison, all of the outer planets are primarily made up of gaseous material and contain rings.

Therefore, the correct choice is B.

According to the diagram, the block should be moving in which direction?

Oxana [17]

D. The block should move to the left.

Since the forces are in opposite directions the difference of these forces determines the magnitude and direction of the block. Therefore,

20 N left - 10 N right = 10 N left

Answer:

1.27seconds

Explanation:

Speed = 324 m/s , Distance = 411.48m

Time = Distance/Speed

Time = 411.48/324 seconds

Time = 1.27seconds ( Ans)

If the Sun were to collapse into a black hole, the point of no return for an investigator would be approximately 3 km from the c

Marysya12 [62]

Answer:

1.97*10⁴N .He cannot survive.

Explanation:

The<em> </em><em>Tidal force</em> can be defined as the difference in force between center of two bodies like center of earth and other bodies.This force stretches the body too and fro from the center of mass of another body due to the difference in the gravitational force.

The tidal force is responsible for various phenomena like ocean tides,celestial body tearing up.

The tidal force is the effect of massive body gravitationally affecting another body.

The tidal force is the difference between the gravitational force of two bodies and directly proportional to the mass of body affecting another body and inversely proportional to the square of radius of the distance between center and the object.

Here let us consider height of person as 2m and d=1m

ΔF= $\frac{GMm}{(R-d)^{2} }$ - $\frac{GMm}{(R+d)^{2} }$

=GMm[ $\frac{1}{(R-d)^{2} }$ - $\frac{1}{(R+d)^{2} }$ ]

=(6.67*10⁻¹¹)(1.99*10³⁰)(1.0)[ $\frac{1}{(300*10^3-1)^{2} }$ - $\frac{1}{(300*10^3+1)^{2} }$ }

ΔF=1.97*10⁴N.

Thus he cannot survive
