Electrical energy, a form of kinetic energy results in a flow of electrons.
<u>Explanation:
</u>
Any kind of energy related to flow or motion of objects or particles falls under the category of kinetic energy. When an object undergoes motion or flow, it will exhibit velocity leading to kinetic energy, or energy utilized from the force applied for the motion.
In this case, the electrons will flow between the molecules due to the electric current supplied to it leading to the electrical energy, the flow of electrons generate current in opposing direction to the flow of electrons. Thus, current can be produced due to the flow of electrons on applying electrical energy.
Answer:
Momentum is the product of a moving object's mass and velocity . ... When two objects collide the total momentum before the collision is equal to the total momentum after the collision (in the absence of external forces). This is the law of conservation of momentum. It is true for all collisions.

Answer:
3000W
Explanation:
Given parameter:
Weight of safe = 2000N
Height of lift = 6m
Time = 4s
Unknown:
Power used by Rudolph = ?
Solution:
Power is the rate at which work is being done. It is expressed as:
Power = 
Work done = Weight x height = 2000 x 6 = 12000J
Power = 
= 3000W
Answer:
The right solution is "0.50 m/s²". A further explanation is provided below.
Explanation:
The given values are:
Mass,
m = 50 kg
Speed,
v = 10 m/s
Rolling friction acting backward (south),
f = 10 N
Air resistance acting backward (south),
= 15 N
The total force acting will be:
⇒ 
On substituting the given values, we get
⇒ 
⇒ 
Now,
⇒ 
On substituting the given values, we get
⇒ 
⇒ 
The horizontal acceleration will be "0.50 m/s²" because the (-)ve sign indicates it in south direction.
Answer:
Explained.
Explanation:
Only the first question has been answered
In a period from left to right the nuclear charge increases and hence nucleus size is compressed. Thus, atomic radius decreases.
In transition elements, electrons in ns^2 orbital remain same which is the outer most orbital having 2 electrons and the electrons are added to (n-1) d orbital. So, outer orbital electron experience almost same nuclear attraction and thus size remains constant.
