Answer:
Total strain when the stress was equal to 210 MPa = 0.101
Explanation:
See attached pictures.
.00135 j
K.E. = 1/2 m v^2
= 1/2 * .03 * .3^2 = .00135 j
.........
Option B..... ...
C. 441 N
Gravitational force between two objects can by calculated by the formula
= G m₁m₂ / r² , m₁ and m₂ are masses at distance r
= ( 6.67 x 10⁻¹¹ x 45 x 5.98 x 10²⁴) / ( 6.38 x 10⁶ )²
= 44.09 x 10
= 440.9 N
= 441 N .
