Atoms form chemical bonds using:
a. electrons in the innermost energy level
b. electrons in the outermost energy level
c. protons and electrons
Answer:
electron in the outermost
Explanation:
These are the electrons available for bonding or transfer
protons do are not involved in actual bonding
Answer:
b
Explanation:
Atoms form chemical bonds using electrons in the outermost energy level, otherwise known as valence electrons.
For atoms to bond, they must either gain or lose electrons.
By gaining electrons, the atom attains a negative charge.
By losing electrons, the atom attains a positive charge.

A car accelerates at a rate of 8.8m/s² with a force from the tires of 19,976N. What is the mass of the car?
A.1800kg
B.2270kg
C.1360kg
D2140kg
Answer:
B. 2270 kg
Explanation:
We know that :
Force = Mass x AccelerationWe are given :
Force = 19,976 NAcceleration = 8.8 m/s²Finding mass
19,976 = 8.8 x massmass = 19,976/8.8mass = 2270 kgA 3.0kg weight W is initially at rest on incline AB, which is raised 40° above the horizontal. The effective coefficient is
mu = 0.3 . Through frictionless pulley and strings of negligible mass, a small mass P, 400g, is at rest on a 200g weighting pan.
Draw a free body diagram representing the situation, and use it to determine the acceleration of the system. Use the value of acceleration calculated to determine the relative weight of P in pounds.
(a) The acceleration of the system is determined as 1.58 m/s².
(b) The relative weight of P is pounds is determined as 0.14 lb.
Acceleration of the system
The acceleration of the system is calculated as follows;
W - T = m₂a --- (1)
T = m₁a ----(2)
μmgsinθ - m₁a = m₂a
(0.3 x 3 x 9.8 x sin40) - (0.4 + 0.2)a = 3a
5.67 - 0.6a = 3a
5.67 = 3.6a
a = 5.67/3.6
a = 1.58 m/s²
Relative Weight of PW = ma
W = 0.4 x 1.58
W = 0.632 N = 0.14 lb

A magnetic field of 0.0037 T is measured at a distance of 2 cm from a long
straight current carrying wire. What is the magnitude of the current flow in the
wire?
Hi there!
We can use Ampère's Law to derive an expression for the magnetic field strength produced by an infinitely long current-carrying wire:
[tex]\oint B \cdot dl = \mu_0 I_{encl}[/tex]
B = Magnetic Field Strength (T)
dl = Differential length along path
μ₀ = Permeability of Free Space (Tm/A)
I = Enclosed current (A)
The integral is a cross product, so the cosine of the angle between the magnetic field and the path of integration is used. However, for a straight current-carrying wire, the path is ALWAYS parallel to the magnetic field, so since cos(180) = 1, we can disregard the cross product.
Additionally, the path of integration is equivalent to:
[tex]l = 2\pi r[/tex]
[tex]B \cdot l = \mu_0 I_{encl}\\\\B * 2\pi r = \mu_0 I_{encl}\\\\B = \frac{\mu_0 I_{encl}}{2\pi r }[/tex]
Rearrange to solve for enclosed current:
[tex]I_{encl} = \frac{2\pi rB}{\mu_0} = \frac{2\pi (0.02)(0.0037)}{(4\pi *10^{-7})} = \boxed{370 A}[/tex]

A positive charge is fixed at point (−4,−3) and a negative charge − is fixed at point (−4,0). Determine the net electric force ⃗ net acting on a positive test charge + at the origin (0,0) in terms of the given quantities and physical constants, including the permittivity of free space 0. Express the force using unit vector notation. Enter precise fractions rather than entering their approximate numerical values.
The net electric force acting on a positive test charge at the origin is determined as ¹/₉(kq₁q₂).
Net electric force on the chargesThe net electric force on the charges is calculated as follows;
F = kq₁q₂/r²

k is coulomb's constantq₁ and q₂ are the chargesr is the distance between the chargesDistance between the charges[tex]|r| = \sqrt{(x_2-x_1)^2+ (y_2-y_1)^2} \\\\|r| = \sqrt{(-4--4)^2+ (0--3)^2} \\\\|r| = \sqrt{(0)^2 + (3)^2} \\\\|r| = 3 \ units[/tex]
[tex]F_{net} = \frac{kq_1q_2}{3^2} \\\\F_{net} = \frac{1}{9} (kq_1q_2) , \ N[/tex]

A 12 V battery is connected to a device and 24 mA of current is measured. If the device obeys Ohm's law, how much current is present when a(n) 108 V battery is used?
Answer:
Correct answer: Ic₂ = 48 mA = 48 · 10⁻³ A
Explanation:
U₁ = 12 V DC first battery voltage
Ic₁ = 24 mA = 24 · 10⁻³ A Intensity of current with the first battery
U₂ = 24 V DC second battery voltage
Ic₂ = ? Intensity of current with the second battery
The formula that applies to a simple electric circuit under the Ohm's law is:
R = U / Ic
where R is the total resistance in the electrical circuit and it is constant.
R = U₁ / Ic₁ = U₂ / Ic₂ ⇒ U₁ / Ic₁ = U₂ / Ic₂ ⇒ Ic₂ = (U₂ · Ic₁) / U₁
Ic₂ = (24 · 24) / 12 = 48 mA
Ic₂ = 48 mA = 48 · 10⁻³ A

The specific heats of water and copper are 4.2 and 0.39 kJ/kgK, respectively; the heat of fusion of ice is 335 kJ/kg.
Answer:
.389 kg of ice required
Explanation:
The heat absorbed by melting the ice and warming it to 30 C
must be equal to the heat lost by cooling the existing water and the copper from 100 to 30 C
First, melt the ice (this occurs at a constant temperature)
x * 335 kj/kg and warm this water x * 4.2 kj/kg-k * 30 k
(x = kg of ice required)
then cool the copper and the .6 kg water from 100 to 30 C (70 degrees)
.1 kg * .39 * 70 K + .6kg * 4.2 kj/kg-K * 70 K
then equate the two amounts of heat
x ( 335 + 4.2 *30) = .1 * .39 * 70 + .6 * 4.2 * 70
solve for x = .389 kg
