Answer:
Explanation:
The function of the current with respect to time is the derivative of the charge function with respect to time t. We can apply chain rule to differentiate it:
Answer:
electrons are NEGATIVE not POSITIVE ionic bond
Explanation:
Answer:
Explanation:
For acceleration due to gravity
g = GM / R² ---------------------------- ( 1 )
At height 2R , radius of orbit is 3R .
If speed of satellite be v
m v² / 3R = GMm / (3R)² ( centripetal force = gravitational force )
v² = GM / 3R -------------------------------------- ( 2 )
Dividing (1) and (2)
v² / g = R / 3
v² = gR / 3
v = √( gR / 3 )
The high-speed gas is thrown into space by a supernovae or strong stellar winds which collects i<span>nterstellar</span><span> material, excavating a </span>bubble of hot<span>, </span>ionized gas
