г 
г
Nm
Therefore, the torque on the loop is
Nm
Answer:
Option D: More than 90
Explanation:
Thickness probably depends on temperature. The higher the temperature, the more aliens we expect to be thin.
Velocity
Because velocity is speed with direction. In this scenario, the speed has not changed, but the direction did.
Answer: k = 1163.72 N/m²
Explanation: if the bow obeys hook's law, then force is proportional to extension.
F = ke.
F= Force = 263 N
k = force constant
e = extension = 0.226m
263 = k * 0.226
k = 263/ 0.226
k = 1163.72 N/m²
