Explanation:
The given data is as follows.
Q = 620 C, t = 0.510 hour
First, we will convert hours into seconds. Since, there are 3600 seconds present in 1 hour. Hence, number of seconds present in 0.510 hour are as follows.
= 1836 sec
Therefore, we will calculate the average current as follows.
I =
=
= 0.337 C/sec
It is known that,
1 C/sec = 1000 mA
So,
= 337 mA
Thus, we can conclude that the average current in milliamperes is 337 mA.
Answer:
Magnetic: Magnet being pulled to a metal surface- non- contact force
Friction: skateboard slowing down on a rough surface- contact force
Gravity: Ball falling to the ground - non-contact force
Electrical: Charged balloon pulling up on arm hair - non- contact force
Tension (pull): people playing tug-of-war - contact force
Applied (push): a person pushing a toy car - contact force
Air resistance: wind pushing on the sail of a sailboat - contact force
Spring: springs being pushed together -contact force
Explanation:
A contact force is a type of force that can only act when two bodies touch other physically. Examples of this include a push or a pull.
A non-contact force is a type of force that can only act when two bodies do not touch other physically. Examples include; electric force, magnetic force, etc.
Answer:
we will use universal gas law
Explanation:
First, convert torr to atm
Molar mass = 61.9
Note: I converted Celsius to kelvin and mL to L
Answer:
TRUE
Explanation:
Each electronic shell in an atom is composed of subshells, which are denoted by the symbol s, p, d and f. These subshells are represented by the principal quantum number (n) and the azimuthal quantum number (ℓ).
Each subshell can hold a fixed number of electrons, which is equal to (4ℓ + 2) electrons.
For, d subshell the value of ℓ = 2.
<u>Therefore, the maximum number of electrons that a d-orbital can hold = (4ℓ + 2) electrons = (4×2 + 2) electrons = 10 electrons.</u>
It avoids confusion through scientists. If you think, they could be practicing or studying in varying countries and something uniform for science avoids all confusion!
