Answer:
Friction works against the motion and acts in the opposite direction. When one object is sliding on another it starts to slow down due to friction. ... By rubbing them together we generate friction and, therefore, heat. The force F of friction pushes back on the block
Explanation:
Answer:
<h2>1320 J</h2>
Explanation:
The work done by an object can be found by using the formula
workdone = force × distance
From the question we have
workdone = 600 × 2.2
We have the final answer as
<h3>1320 J</h3>
Hope this helps you
Answer:
B
Explanation: Because conduction is when an object touches another object and convection happens with boiling water or the water cycle, the particles/water fall and rise.
Answer:
12.64968 Hz
Explanation:
v = Velocity of sound in seawater = 1522 m/s
u = Velocity of dolphin = 7.2 m/s
f' = Actual frequency = 2674 Hz
From Doppler effect we get the relation
The frequency that will be received is 2661.35032 Hz
The difference in the frequency will be
