B. become a white dwarf star
It will swell, shed its layers, and become a white dwarf star.
I know the sun does not have enough mass to become a supernova or a black hole.
Answer:
A
Explanation:
Voltage, V = Current, I x Resistance, R (V is directly proportional to I where R is constant of proportionality)
This means that when Voltage is increased, Current increases and when voltage is decreased, current decreases (and the inverse is true). Through all this though, resistance remains constant regardless.
Answer:
b) 450 V
Explanation:
We are given that
Total charge, q=10nC=
Radius, r=20 cm=
1 m=100 cm
x=15 cm=0.15 cm
We have to find the electrical potential 15 cm above the center of a uniform charge density disk .
We know that
Where
Electric potential,
Where
Using the formula
Hence, option b is correct.
Answer:
copying another writer's work with no attempt to acknowledge that the material was found in external source is considered as a direct plagiarism.
In this problem, we apply the equation regarding kinematics expressed as vf^2 = v0^2 + 2as vf eventually becomes zero because the ball stops in the end. a = -9.8 m/s2s = 2 metres this time
This gives initial velocity, vo equal to 6.26m/s
now 6.26-(-8.85) = 15.11m/s
change in velocity/change in time = average acceleration 15.11/(12/1000) = 1259.167 m/s^2
