How are electrons distributed in the molecular orbitals, when the 1s orbitals of two hydrogen atoms combine to form a hydrogen m

Evgesh-ka [11]

Answer:

2 Electrons

Explanation:

Both the Hydrogen atom will share electron equally by covalent bonding. so there will be 2 electron in the bonding molecular orbital.

A conductor bent into a semicircle of total length 3.88 m is placed in a 2.0 T magnetic field perpendicular to the plane of the

ivolga24 [154]

Answer:

Magnetic force, F = 38.95 N

Explanation:

Given that,

Length of the conductor, L = 3.88 m

Magnetic field, B = 2 T

Current flowing in the conductor, I = 5.02 A

The magnetic field perpendicular to the plane of the semicircle. The angle between the magnetic field and the plane is 90 degrees. The expression for the magnetic force is given by:

$F=ILB\ sin\theta$

$F=ILB$

$F=5.02\times 3.88\times 2$

F = 38.95 N

So, the magnitude of the total force acting on the conductor in the magnetic field is 38.95 N. Hence, this is the required solution.

The skid marks from a car involved in an accident measured 73 feet. To the nearest tenth, what was the speed of the car before t

labwork [276]

Answer:

speed of the car before the brakes were apply is 12.35 m/s

Explanation:

given data

accident measured distance = 73 feet = 22.25 m

to find out

speed of car before the brakes

solution

we consider here coefficient of kinetic friction between the road and the tires is 0.35

and we take speed of the car just before skidding = u

and final speed of car will be v = 0

now we apply here work energy theorem

0.5 mv² - 0.5 mu² = (- coefficient of kinetic friction × mass × g ) distance .......1

0.5( v² -u² ) = (- coefficient of kinetic friction × g ) distance

put here value and we get

0.5 ( 0 - u² ) = (- 0.35 × 9.8 ) 22.25

solve it we get

u = 12.35

speed of the car before the brakes were apply is 12.35 m/s

What is the eccentricity of a planet's orbit if the focal distance is 8 and the major axis is 32?

grin007 [14]

Focal distance of an ellipse is given by the formula

$f = ae$

here a = length of semi major axis

e = eccentricity of the path

now here we know that

length of major axis for the path of planet is given as 32 units

so here we can say

$2a = 32 units$

$a = 16 units$

so length of semi major axis is 16 units

focal distance for the planet path is given as 8 units

now from the above formula we can write

$f = a*e$

$8 = 16*e$

$e = \frac{8}{16}$

$e = \frac{1}{2} = 0.5$

so eccentricity for the path of planet will be 0.5
