Answer:

579600J

Explanation:

Given parameters:

Height of the building  = 828m

Weight of the man  = 700N

Unknown:

Work done by the man  = ?

Solution:

The work done by the man is the same as the potential energy expended.

 Work done:

             Work done  = Weight x height  = 700 x 828

        Work done  = 579600J

When will an object sink in water, according to Archimedes' principle?​
inna [77]

Answer:

If the buoyant force is greater than the object's weight, the object will rise to the surface and float. If the buoyant force is less than the object's weight, the object will sink. If the buoyant force equals the object's weight, the object will remain suspended at that depth.

Explanation:

Not much explaining to do here!

GrogVix [38]

The distance from Buzău to Iaşi is 72 km. Find out the time a vehicle travels this distance if it has a speed of 72 km per hour. Expresses the speed in the unit of measurement in SI. I give the crown! Thank you

Answer:

3600seconds

Explanation:

Given parameters:

Distance  = 72km

Speed  = 72km/hr

Unknown:

Time it takes for the vehicle to travel the distance  = ?

Solution:

Speed is the distance divided by time;

               Speed = \frac{distance}{time}

             time  =\frac{distance}{speed }  

 Insert the parameters;

         time  = \frac{72}{72}  = 1hr

The SI unit of time is in seconds;

3600 seconds is 1hr

The time is 3600seconds

Valentin [98]

Explanation:

The orbit of the planet is considered to be stable and does not change over time. This means that the force of gravity and inertia are perfectly balanced. Leading to forward motion of Planet and moons under force of gravity of some other large body(Most probably stars).This is in turns leads to formation of orbit.
