Answer: D. Acceleration of Object A is twice of that of the acceleration of Object B.
<span> = r x F </span>
<span>| τ | = | r x F | = | r | | F | sinΘ </span>
<span>100 = | (0.3)<0, 1, 0> x (F/5)<0, 3, -4> | </span>
<span>5000/3 = | F | | <0, 1, 0> x <0, 3, -4> | </span>
<span>5000/3 = | F | | <-4, 0, 0> | </span>
<span>5000/3 = | F | * 4 </span>
<span>| F | = 1250/3 </span>
<span>| F | = 417 N </span>
<span>Check: </span>
<span>τ = r x F </span>
<span>100<-1, 0, 0> = 0.3<0, 1, 0> x 250/3<0, 3, -4> </span>
<span>100<-1, 0, 0> = 25 ( <0, 1, 0> x <0, 3, -4> ) </span>
<span>100<-1, 0, 0> = 25 ( <-4, 0, 0> ) </span>
<span>100<-1, 0, 0> = 100<-1, 0, 0> </span>
<span>What the other people forgot was that you need the angle from the y-axis, which would be Θ = arctan(O/A) = arctan(z/y) = arctan(-4/3) = -53.1°. Then you take the sine of that to get 0.8. There is more work being done on the z-vector than there is on the y-vector, so the force is distributed (0.6) in the y-direction, and (0.8) in the z-direction (0.6² + 0.8² = 1). </span>
Hi there!
The Legislative Branch of government includes the House of Representatives and the Senate. This branch makes laws. Its powers include passing laws, originating spending bills (House), impeaching government officials (Senate), and approving treaties (Senate).
Hope this helps!! :)

Answer :
The time is ![1\times10^{5}\ yrs](https://tex.z-dn.net/?f=1%5Ctimes10%5E%7B5%7D%5C%20yrs)
(B) is correct option.
Explanation :
Given that,
Diameter = 100000 light year
Velocity = 0.99 c
We need to calculate the time
Using formula of time
![t = \dfrac{d}{v}](https://tex.z-dn.net/?f=t%20%3D%20%5Cdfrac%7Bd%7D%7Bv%7D)
Put the value into the formula
![t =\dfrac{100000 c}{0.99c}](https://tex.z-dn.net/?f=t%20%3D%5Cdfrac%7B100000%20c%7D%7B0.99c%7D)
![t =1\times10^{5}\ yrs](https://tex.z-dn.net/?f=t%20%3D1%5Ctimes10%5E%7B5%7D%5C%20yrs)
Hence, The time is ![1\times10^{5}\ yrs](https://tex.z-dn.net/?f=1%5Ctimes10%5E%7B5%7D%5C%20yrs)
