Yes the main benifit can be recyclation of energy
- The example can be seen in powerbanks or inverters
- The chemical energy present inside the battery can be used to convert itself into electric energy.
- Which can help us in climate protection
Answer: The final velocity of both man and hokey puck will be 0.056 m/s.
Explanation: We are given 2 objects and are undergoing collision. The final velocity of both the objects is same. To calculate the final velocity, we will use the principle of conservation of momentum.
This principle states that when the objects that are colliding makes up a system, then the total momentum will remain constant if no external force is applied on it.
Sum of Initial momentum of two objects = Sum of Final momentum of the two objects
Mathematically,
...(1)
where,
are the mass, initial velocity and final velocity of the first object.
are the mass, initial velocity and final velocity of the second object.
Here, man and hockey puck are moving together after the collision, so their final velocities will be same.
Putting values in equation 1, we get:
The final velocity of man and hockey puck is 0.056 m/s.
Not sure what you mean could you be a little more detailed
Answer:
There are many effects of radiation to the human body. (if you watch the 100, you'll see what happens)
Exposure to very high levels of radiation, such as being close to an atomic blast, can cause acute health effects such as
1. weakness
a/ fatigue,
b/ fainting,
c/ confusion.
2.Bleeding from the nose,
a/ mouth,
b/ gums,
c/ rectum
3. Bruising,
a/ skin burns,
b/ open sores on the skin,
c/ sloughing of skin.
4. Dehydration.
5. Diarrhea, bloody stool.
6. Fever.
7. Hair loss.
8. Inflammation of ex
Fluorescence
when a substance absorbs external radiation in any form and gives of a glow or luminescence it is considered as Fluorescence.
