Whether it is possible for a person with a 70-year life span to travel farther than light travels in 70 years.

Explanation of Solution
Introduction:
According to
If man travels in space at a speed of 99.99 % of light, he could travel slightly more than 70 light years that he can travel in a single year of his own time. So, this 70 earth year trip may take much shorter for the person who is travelling.
Conclusion: Yes, it is possible for a person with 70 years life span to travel farther than light travels in 70 years.

The coefficient of kinetic friction is 0.20. The attached string is parallel to the incline and passes over a massless, frictionless pulley at the top. Block B, with a mass of 15.0 kg. is attached to the dangling end of the string. What is the acceleration of Block B in m/s? show all steps pleasearrow_forward
- When current is flowing through the coil, the direction of the torque can be thought of in two ways. Either as the result of the forces on current carrying wires, or as a magnetic dipole moment trying to line up with an external field (e.g. like a compass). Note: the magnetic moment of a coil points in the direction of the coil's magnetic field at the center of the coil. d) Forces: We can consider the left-most piece of the loop (labeled ○) as a short segment of straight wire carrying current directly out of the page at us. Similarly, we can consider the right-most piece of the loop (labeled ) as a short segment straight wire carrying current directly into the page, away from us. Add to the picture below the two forces due to the external magnetic field acting on these two segments. Then describe how these two forces give a torque and determine if the torque acts to rotate the loop clockwise or counterclockwise according to this picture?
