A perfectly spherical orange is split into four equal sections. if the radius of the orange is 4 centimeters, what is the total
2 answers:
The total surface area of one slice will be 64 π cm².
<h3>What is the total surface area?</h3>The total surface area includes the base as well as the curving component. It is the whole area covered by the object's surface.
The total area of a form with a curved surface and base is equal to the sum of the two areas.
The total surface area of the sphere will be;
Hence the total surface area of one slice will be 64 π cm².

Answer:
The speed of q₂ is
Explanation:
Given that,
Distance = 0.4 m apart
Suppose, A small metal sphere, carrying a net charge q₁ = −2μC, is held in a stationary position by insulating supports. A second small metal sphere, with a net charge of q₂ = −8μC and mass 1.50g, is projected toward q₁. When the two spheres are 0.800m apart, q₂ is moving toward q₁ with speed 20m/s.
We need to calculate the speed of q₂
Using conservation of energy
Put the value into the formula
Hence, The speed of q₂ is
