Answer:
By Factor of 4
Explanation:
The expression for centripetal acceleration is given as,
a = v²/r........... equation 1
Where a = centripetal acceleration, v = speed, r = radius of the circle.
Case 1
Given: v = 150 m/s, r = 500 m
Substitute into equation 1
a = 150²/500
a = 22500/500
a = 45 m/s².
Case 2
Given: v = 300 m/s, r = 500 m
Also substitute into equation 1
a = 300²/500
a = 180 m/s²
Factor of change of the acceleration = 180/45
Factor of change of the acceleration = 4.
Hence the acceleration will change by a factor of 4
The energy from the sun that reaches the corn is about two billionths.
<span>a = (v2 - v1)/t= acceleration formula
a = (70 - 0)/7
a = 10 km/hr/sec
-----
It's better to use as few units as possible.
10 km/hr = 10 km*1000 m/km/(1 hr*3600 sec/hr) = 25/9 m/sec
a= 25/9 m/sec/se</span>
This is what e=mc² means.
So rest energy is RH side of equation that is its mass times speed of light squared.
