Its easy to create a visual and see major differences between data. If something takes up a large portion of the pie, its easy for you to tell just by looking at it
Answer:
Their kinetic energy will increase but potential energy will decrease.
Explanation:
Given that
Initial velocities of electron and proton is zero.
We know that ,electron have negative charge and proton have positive charge it means that they will attract to each other.We know that opposite charge attract to each other and same charge repels to each other.
It means that the velocities of proton and electron will increase and that leads to increase in the kinetic energy of proton and electron.
We know that potential energy U
So when r will decrease then U will increase but in negative direction it means that U will decrease.
So we can say that their kinetic energy will increase but potential energy will decrease.
Answer:r=242ohms
Explanation:
Power(p)=50w
Volt(v)=110v
Resistance(r)=?
Power(p)=((volt)^2)/(resistance(r))
50=110^2/r
Cross product
50xr=110^2
50r=12100
r=12100/50
r=242ohms
Answer:
Step 1: Draw the vectors[Ref. Fig.]
Consider there are two vectors A and B such that B is perpendicular to the resultant R
Since the resultant is perpendicular to vector B we will get a right-angled triangle
Step 2: Equation formation
From the triangle
∣A∣2=∣B∣2+∣R∣2 ....(1)
Given , ∣R∣=∣A+B∣=12 ....(2)
∣A∣+∣B∣=18 ....(3)
Step 3: Solving Equations
Equation (3) and (1)⇒ ∣A∣2=(18−∣A∣)2+(12)2
⇒ ∣A∣2=182+∣A∣2−2×18∣A∣+

Mechanical waves<span> require an initial </span>energy<span> force. Once this </span>energy<span> is added, the </span>wave<span> travels through the medium until all its </span>energy<span> is </span>transferred<span>. In contrast, electromagnetic </span>waves<span> require no medium, but can still travel through one.</span>
