Estimate the kinetic :1hkv*qr x89wdn1k jqenergy of tvht/+t xat3 f2sh07 bzhe Earth with respect to the Sun as the sum of t3xhva 0/ 2tbhs+t7ztfwo terms,
(a) that due to its daily rotation about its axis,$KE_{daily}$= $\times10^{29 }$ J
(b) that due to its yearly revolution about the Sun. $KE_{yearly}$+ $\times10^{33 }$ J [Assume the Earth is a uniform sphere with $6 \times10^{ 24}$ kg and $6.4 \times10^{6 }$ m and is $1.5 \times10^{8 }$ km from the Sun.]$KE_{daily}$ + $KE_{yearly}$ = $ \times10^{33 }$ J
