Answer:
0.495 m/s
Explanation:
= tension force in the string connecting the two objects
= Mass of the object on inclined plane = 250 g = 0.250 kg
= Mass of the hanging object = 150 g = 0.150 kg
= acceleration of each object
From the force diagram, force equation for the motion of the object on the inclined plane is given as
From the force diagram, force equation for the motion of the hanging object on the inclined plane is given as
Using the above two equations
= height dropped by the hanging object = 10 cm = 0.10 m
= Speed gained by the object
Speed gained by the object can be given as
Answer:
Thrust is the force acting normally to a surface. So, Thrust = 1200 N. And , Pressure = Thrust / Area. = 1200 / 0.001. = ...
Explanation:
this right like me
To determine the heat released by the process of condensation, we simply multiply the amount of the gas that condensed to the latent heat of vaporization. We do as follows:
Heat released = 21 J/g (12.0 g ) = 252 J of heat released
Answer:
840 W
Explanation:
The energy expended in hoisting the diver up is given by
<em>m</em> is the mass of the diver, <em>g </em>is the acceleration due to gravity and <em>h</em> is the height.
Using the values in the question and taking <em>g</em> as 9.8 m/s²,
The power is given by
<em>t</em> is the time.
Hence,
The study of the moon as well as the stars is astronomy
