Answer:
Explanation:
the variations in riser height or tread depth should not be grater than that is equal to 9.5 mm but the maximum riser height should be the 
but variation in riser height should not exceed to . The minimum riser height should be 7 inches which is equal to the 178 mm
The correct option is: Option (D) not turn at all.
Explanation:
As the bar magnet is at rest, there is no change in magnetic flux. It means the change in magnetic flux in the magnetic flux in the loop is zero. Hence the induced current in the loop is zero and the loop will never turn at all. Therefore, the correct option is (D).
Answer:
792 J
Explanation:
The total energy of the ball is E = U + K where U = potential energy = mgh and K = kinetic energy = 1/2mv²
E = mgh + 1/2mv² where m = mass of ball = 2.0 kg, g = acceleration due to gravity = 9.8 m/s², h = height of building = 20.0 m, v = initial velocity of ball = 20.0 m/s.
So, substituting the values of the variables into E, we have
E = mgh + 1/2mv²
= 2.00 kg × 9.8 m/s² × 20.0 m + 1/2 × 2.00 kg × (20.0 m/s)²
= 392 J + 400 J
= 792 J
Answer:
13993 Nm
Explanation:
Assume the load is vertical, the horizontal moment arm that is perpendicular with the load can be calculated
Since torque is the product of load and moment arm, with maximum load being 869N the maximum torque that it can handle is
T = Fs = 869 * 16.1 = 13993 Nm
