A compound Machine is 2 machines that work together in order to make a task easier.
Answer:
3 : 08 : 10.9
Explanation:
assuming a 12 hour clock
angular velocity of the hour hand is 2π/(3600(12)) rad/s
angular velocity of the minute hand is 2π/3600 rad/s
difference is 2π/3600 - 2π/(3600(12)) = 11(2π/(3600(12)) rad/s
45° = π/4 radians
This angle is covered in a time of
π/4 rad / 22π / (3600(12)) = 900(12) / 22 = 490.909090... s
or about 8 minutes 10.9 s
ANSWER 3:08:10.9
A 50kg object on earth weighs 81.67 on the moon
Answer:0.0242 Nm
Explanation: The distance of 0.145 mm is very small. This will also result in a small ttorque. The question would make more sense if the distance was 0.145 m. Answering with the 0.145 mm as distance :
Changin from mm to m : 1mm=0.001m
0.145 mm = 0.000145 m
The formula for Torque is T=Fxd
Wher F is the force and d is the perpendicular distance between the centre of the bolt and the applied force.
T= 167 x 0.000145 = 0.024215 Nm
