Explanation:

Answer:

amount and speed of traffic on the acceleration lane and expressway.

Answer:

S = v0 t + 1/2 a t^2       a = 0 seems given in the problem

Vp  t = Vr t + 16

both travel for time t but the police car is going faster and travels 16 km farther

t (Vp - Vr) = 16

t = 16 km / (100 - 80) km/hr

t = 16 / 20 hr = 4/5 hr = 48 min

The climate change can directly impact the formation of hurricanes because increasing temperature increases intensity of hurricanes.

Evaporation increases as temperatures rise which also causes the transfer of heat from the oceans to the atmosphere. As the storms travel across oceans whose water is warm, they absorb more water vapor and heat which increases rainfall as well as intensity of hurricanes.

So we can conclude that the climate change impacted the formation of hurricanes due to increasing temperature that increases intensity of hurricanes.

The light oscillates electrons which then absorbs some of the energy and reemit it thereby causing a delay.

This is defined as a subatomic particle which has a negative charge. In the glass of water the light oscillates the electrons which absorbs some energy.

The re-emission is what slows light when it passes from air into glass or water.

Answer:

8

Explanation:

It is because the outermost energy level carries a maximum of 8 electrons

8 electrons do most atoms seek to have in their outermost shell, causing covalent bonds to form

The interatomic bond is formed when two atoms share an electron pair. The electrical attraction of their nuclei for the identical electrons causes the binding.

When the total energy of the bound atoms is lower than that of widely spaced atoms, a covalent bond is formed.

When an atom's outermost electron shell is full, it is the most stable and least reactive. The octet rule states that most key biological elements require eight electrons in their outermost shell to be stable.

Hence 8 electrons do most atoms seek to have in their outermost shell, causing covalent bonds to form

Answer:

The Electric Force on Negative Charge is 2.968 N

Explanation:

charge on each corner, q = 2.38 micro coulomb

Side of square, a = 75.2 cm

Coulombic constant, K = 8.98755 x 10^9 Nm²/C²

sides of the square are A,B,C and D

and all sides of a square are equal so

AB = BC = CD = DA = 75.2 cm = 0.752 m

Diagonal, AC = BD = 1.414 x 0.752 = 1.06 m

Electric field at D due to charge at A

EA= Kq÷AB^2

= 8.98755×10^9 × 9.87×10^-6 ÷ 0.752^2

EA= 156863.82 N/C

Similarly Electric field at D due to charge C

EC=Kq÷CD^2

= 8.98755×10^9 ×9.87×10^-6 ÷ 0.752^2

EC= 156863.82 N/C

Electric field at D due to charge at BB

EB=Kq÷BD^2

EB=8.98755×10^9 × 9.87×10^-6 ÷ 1.06^2

EB=78949.01 N/C

Resolve the compoents

Ex = EA + EB cos 45

Ex = 156863.82 + 78949.01 x 0.707

Ex = 212689.2 N/C

Ey = EC + EB Sin 45

Ey = 156863.82 + 78949.01 x 0.707

Ey = 212689.2 N/C

The resultant electric field is

E = 1.414 x 212689.2 = 300787.95 N/C

the electric force on the negative charge is

F = q x E

F = 9.87 x 10^-6 x 300787.95

F = 2.968 N

The initial angular momentum of the propeller before the torque was applied will be 32 kg m²/s.

Torque is the force's twisting action about the axis of rotation. Torque is the term used to describe the instant of force. It is the rotational equivalent of force. Torque is a force that acts in a turn or twist.

The amount of torque is equal to force multiplied by the perpendicular distance between the point of application of force and the axis of rotation.

The given data in the problem is;

The rotational inertia is,I  = 2.0 kg m²

The clockwise torque is, T = 4.0Nm

The time period is,t= 4.0s,

The angular speed is,ω= 24 * (rad)/s

The initial angular momentum of the propeller is,I₀

The angular acceleration is found by the relation;

[tex]\rm \tau = I \times \alpha \\\\ \alpha =\frac{\tau}{i} \\\\ \alpha =\frac{4.0}{2.0} \\\\ \alpha= 2.0 \ rad/sec^2[/tex]

The initial angular velocity is found as;

[tex]\rm \omega_f = \omega_0 + \alpha t \\\\ \omega_0 = \omega_f -\alpha t \\\\ \omega_0 =24 -[(-2.0)\times 4.0)] \\\\ \omega_0 = 16 \ rad/sec[/tex]

The initial angular momentum of the propeller is found as;

[tex]\rm L_0 = I \omega_0 \\\\ L_0 = 20 \times (1.6) \\\\ I_0 = -32 \ kgm^2/s[/tex]

Hence,the initial angular momentum will be 32 kg m²/s.

Explanation: In an inelastic collision, the object hits the item and stays with it. Therefore, both momentum and kinetic energy need to be presen.t

Answer:

Look below.

Explanation:

1.) The resistance of a light bulb filament is effected by both length and cross-sectional area. Thicker wires have less resistance. A 120-Watt bulb has a greater current and a smaller resistance. Thus, a 120-Watt bulb must have a thicker filament than a 60-Watt bulb (assuming the lengths of the filaments are identical). We also think of lightbulbs in terms of their power ratings in watts. Let us compare a 25-W bulb with a 60-W bulb. Since both operate on the same voltage, the 60-W bulb must draw more current to have a greater power rating. Thus the 60-W bulb’s resistance must be lower than that of a 25-W bulb. If we increase voltage, we also increase power. For example, when a 25-W bulb that is designed to operate on 120 V is connected to 240 V, it briefly glows very brightly and then burns out. Precisely how are voltage, current, and resistance related to electric power?

2.) Energy transferred = 120 × 2 = 240 J. This equation can be rearranged to V = E ÷ Q. So voltage is energy transferred divided by charge.

3.) Power= Voltage × Current

4.) W=Pt
