(a) The average number of charge carriers flowing past per second is 1.8 x 10⁻⁶ A
(b) The average current delivered in the given time is 2.56 x 10⁶ A.
(c) The time taken to deliver the charge is 32,166.7 s.
Average number of charge flowing per secondThe average number of charge flowing per second is calculated as follows;
I = Q/t
I = (45 x 10⁻⁹) / (25 x 10⁻³)
I = 1.8 x 10⁻⁶ A = 1.8μ A
Average currentThe average current is number of charge flowing in a second.
I = Q/t
Charge of one electron = 1.6 x 10⁻¹⁹ C
Charge of 56 x 10¹⁶ electrons = 56 x 10¹⁶ x 1.6 x 10⁻¹⁹ C = 0.0896 C
I = (0.0896) / (0.035 x 10⁻⁶)
I = 2.56 x 10⁶ A
Time taken to deliver the chargeTotal charge in 2+ ions = 2F
1 Faraday = 96,500 C
2F = 2 x 96,500 C = 193,000 C
At the given amount of current, the time taken to deliver the charge is calculated as follows;
Q = It
t = Q/I
t = (193,000 )/6
t = 32,166.7 s = 8.9 hours

Some natural hazards are preceded by geologic activities that allow for reliable predictions; other natural hazards occur suddenly, with no notice, and are not yet predictable.
TrueThere are some disasters that can be predicted like tornadoes, tsunamis etc.. But some hazards like earthquake cannot be predicted. Still the technology has not developed so much that it could predict earthquakes...~
Answer:
True
Explanation:
Yes we became modern a lot and are too ahead in terms of technology .We can predict cyclones way before it happens .We can predict tornadoes by measuring air pressure.But we are still unable to predict some hazardous things such as earth quake.what will be the final velocity of a vehicle, if it started from rest and accelerates at 4m/s² after 5 seconds?
Answer:
v = 20 m/s
Explanation:
Let's use v = u + at for uniform acceleration.
v = finaly velocity
u = initial velocity
a = acceleration
t = time
Since we start from rest, our initial velocity is zero.

If a load of 600 N is overcome by a simple machine using an effort of 400 N. Calculate the mechanical advantage.
ㅤ➙ Mechanical Advantage= 1.5
Solution:Mechanical advantage allow to perform tasks much easier in terms of the force needed to apply, but must always obey the conservation of energy. Mechanical advantage is the measure of the ratio of output force to input force needed in a system, used to analysis the force in simple machines like livers and pulleys.

A tea kettle is boiling on the stove, and all of a sudden the whistle in the spout of the kettle starts shrieking. Steam rising from the boiling water causes the whistle to sound. What part of the water cycle does the steam represent
Answer:
Condensation is your answer
Explanation:
Condensation is the process of steam rising back into the atmosphere and the steam would be the evaporation "steam" hope this helped
Steam rising from the boiling water causes the whistle sound, which means that the convection part of the water cycle is present here.
What is convection?The process of convection entails the movement of a heated fluid, such as air or water, in order to transfer heat.
Convection is caused by the fact that most fluids have a tendency to expand when heated, which causes them to become less dense and rise due to the increased buoyancy. The homogeneous heating of air in a heated room or water in a kettle is due to circulation generated by this effect: heated particles expand the area they move in by moving faster against each other, rise, and afterwards cool and close again, increasing density and causing a corresponding sinking.
In forced convection, fluid is carried using mechanisms other than those that result from differences in density with temperature. Examples of forced convection include the air movement by a fan or water by a pump.

What does it mean if electric field lines are close together versus farther apart ?
Answer:
As a result, if the field lines are close together (that is, the field line density is greater), this indicates that the magnitude of the field is large at that point. If the field lines are far apart at the cross-section, this indicates the magnitude of the field is small. (Figure) shows the idea.

Calculate the resistance of the circuit and the amperage through all the resistors.
R = 2 Ω, R1 = 2 Ω, R2 = 4 Ω, R3 = 4 Ω, U2 = 2 V.
Choose one:
a.
R = 10 Ω; I = 5 A; I1 = 2 A, I2 = I3 = 1.5 A.
b.
R = 3 Ω; I = 1,5 A; I1 = 1 A, I2 = I3 = 0,5 A.
c.
R = 3 Ω; I = 2 A; I1 = 1 A, I2 = I3 = 0,5 A.
Answer: C
Explanation:
Resistors R1, R2 and R3 are in parallel so
1/R1 + 1/R2 + 1/R3 = 1 ohm
adding Resistor 'R' make it 2ohm + 1 ohm = 3 ohm
Whereas for current use formula I = V/R

Define force as the cause of acceleration?
Physics
Answer:
In short, a force applied to an object at rest causes it to accelerate in the direction of the force.
Explanation:
Newton's second law says that when a constant force acts on a massive body, it causes it to accelerate, i.e. to change its velocity, at a constant rate.
Answer:
As the force acting upon an object is increased, the acceleration of the object is increased.
Explanation:
The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object.
