A current of 1.8 A delivers 2.5 C of charge.

Physics

Verdich [7]3 years ago

Answer:

<em>1.4 seconds</em><em>,</em><em> </em>which is the third option

Explanation:

Current is defined as the flow of charge per time

Therefore, the equation that relates current, charge and time can be expressed as follows:

I = ΔQ / ΔT

where:

I is the current given = 1.8 ampere

ΔQ is the charge given = 2.5 coulomb

Δt is the time required for the flow of the given charges to give the 1.8 ampere.

Substitute with the givens in the above equation to get the time as follows:

1.8 = 2.5 / ΔT

ΔT = 2.5 / 1.8 = 1.38888 which is approximately 1.4 seconds

" 1.8 Ampere " means "1.8 Coulomb/sec".

(2.5 C)/(1.8 C/sec) = (2.5/1.8) (s) = <em>1.39 sec </em>

I honestly don't see where any of the choices comes from, but the closest one is (C) 1.45 sec.

Dmitry_Shevchenko [17]

Hi!


The correct option would be A) Mendel’s genetics states laws that are now part of the theory of biological evolution.


When Darwin proposed the idea of biological evolution, which revolved around the concept that favorable genes are naturally selected into a species to ensure survival, his theory was criticized as during that time there was the idea that individual traits of two parents would present themselves as a blend in the offspring.

Gregor Mendel's theory of inheritance supported Darwin's idea as it dealt with the transmission of traits in generations through entities called genes, which were present in pairs for a particular trait.


Hope this helps!

Gre4nikov [31]
The correct answer is option A. i.e. An important thing to consider when responding to a driver in front of you that stops suddenly is: the mental state of the other driver.

Our talk or discussion can disrturb the balance of the driver or he can get distracted. So, we must try not to speak much while the driver is driving because by doing this we are putting the life of ourselves in danger. Any distrcaction of driver can cause accident.

A. What is the coefficient of kinetic friction?
Andrews [41]

Explanation:

Coefficient of kinetic friction is the resistive force that opposes the motion of a body as it moves and is in contact with another body.

It is found by dividing the frictional force by the normal force.

  • Friction is a force that opposes motion.
  • Static friction is for bodies that are not in motion
  • Kinetic friction is for moving bodies.
