Atomic radiusmoving from left to right across a period,​

Physics
1 answer:
Ilya [14]3 years ago
6 0

Answer:

Atomic radius decreases moving from left to right across a period.

Explanation:

When we move left to right across a period, the size of atoms generally decreases. It is because within the period the outer electrons are in same valence shell and the number of electrons and proton increases moving from left to right across the the period. It increases the effective nuclear charge resulting in the increased attraction of electron to the nucleus that causes the decreased radius of the atoms.

At what minimum speed must a roller coaster be traveling when upside down at the top of a circle so that the passengers do not f
worty [1.4K]

Answer:

v_{min} \approx 17.153\,\frac{m}{s}

Explanation:

The roller coaster begins with maximum kinetic energy and no gravitational potential energy. The gravitational potential energy reaches its maximum when roller coaster is upside down at the top of the circle. The physical model for the roller coaster is constructed by means of the Principle of Energy Conservation:

\frac{1}{2}\cdot m \cdot v_{min}^{2} = m\cdot g \cdot h

The minimum velocity is:

v_{min} = \sqrt{2\cdot g \cdot h}

Let assume that radio of curvature is measured in meters. Hence:

v_{min} = \sqrt{2\cdot (9.807\,\frac{m}{s^{2}} )\cdot(15\,m)}

v_{min} \approx 17.153\,\frac{m}{s}

PLEASE HELP !! A 10 ohm resistor is connected to a 9V battery how much current is flowing through the circuit?
kompoz [17]

Resitance (R)= 10 Ohm

Potential difference (V) = 9V

V= IR

I= V/R

I= 9/10

I= 0.9 Ampere

Therefore 0.9 Ampere of current is flowing through the circuit.

Two objects, one with a mass of m and one with a mass of 4m are attracted to each other by a gravitational force. If the force o
Natali [406]

By 2nd Newton's Law.

F =m*g

For 1st body

Let it's force be x

thus,

x = m*g --------- eqn 1

For mass 2,

F = 4m*g

g = F/4m -------- eqn 2

For the first body's force interms of second body substitute eqn 2 into 1

x = m*(F/4m)

x = <u>m</u><u>*</u><u>F</u>

4m

x = F/4

Therefore, the force on mass m interms of F is

F/4.
