Answer:
T=1.566 N.m
Explanation:
Given that:
rotational speed of the scrank shaft, N = 2500 rpm
power produced by one cylinder, P = 410 W
We know, in case of rotational power:
where: T= torque
Substituting the respective values in the above eq.
T=1.566 N.m is the torque applied by the each piston of the engine.
Ok the answer to this is quite simple all you do is multiply the objective lens magnification times the eye piece magnification. So multiply 30 times 5. 30 x 5 = 150. So your answer is answer choice C. 150 Hope this helped you. :)
Answer:
the time rate of change of an object is directly proportional to the force acting on it unless an external force act on it to change it states of motion and takes the direction of the force
Answer:
The magnitude of the stone velocity before it hits the ground is 30 m/s.
Explanation:
Given;
initial vertical velocity,
final vertical velocity, = 30 m/s
Apply the following kinematic equation to determine the height of the cliff;
Determine time of the journey;
h = vₓ + ¹/₂gt²
vₓ = 0 (initial horizontal velocity when the stone was thrown vertically downward)
h = ¹/₂gt²
t = √ (2h / g)
t = √ (2(40.82) / 9.8)
t = 2.89 s
When the rock is projected horizontally, the horizontal distance, x = 40.82 m
Initial horizontal velocity,
The final vertical component of the velocity is given by;
The magnitude of the stone velocity before it hits the ground is given by;
Therefore, the magnitude of the stone velocity before it hits the ground is 30 m/s.
