The jogger would have ran about 10 km/h.
Answer:
705.6 N
Explanation:
The object is hanging on the rope, so there are two forces acting on the object:
- The force of gravity, downward, equal to
W = mg
where m is the mass of the object and g the acceleration of gravity
- The tension in the rope, T, upward
Since the object is hanging motionless, the object is in equilibrium, so we can write:
And therefore
For this problem,
m = 72 kg
Substituting,
Answer:
Condenser
Explanation:
The refrigerator work on a simple cycle:
1- When the cold air inside the refrigerator starts to get warm, it loses its thermal energy ot the cold refrigerant which is flowing inside an evaporator. This thermal energy converts the refrigerant into a gas.
2- The refrigerant, in a form of gas, goes to the compressor. The compressor compresses it and increases its temperature even more.
3- Then it goes to the condenser where it loses its most of the thermal energy to the condenser coils. When it loses the energy. it comes back to liquid form.
4.The refrigerant flow back to the evaporator
Cycle continuous
Answer:
Final velocity will be 556.8 m/sec
Explanation:
We have given the average rate of change of velocity that is
Time
Initial velocity of bullet will be zero that is u=0
Now according to first law of motion
v=u+at, here v is final velocity, u is initial velocity and t is time
So
Answer:
0.203 kN
Explanation:
203 N *(1 kN/1000N) = 0.203 kN
