Asia is the largest continent.
Current = (voltage) / (resistance)
= (35 volts) / (1,400 ohms)
= 25 milliamperes
Answer: 110km/h
100+10=110km/h
Explanation:
Motion is defined as a change of position. The frame of reference is usually assumed to be at rest. If one is sitting on a bus, the road appears to be moving backwards relative to the observer. If he/she now walks to the front of the bus, he has a speed relative to the earth which is now greater than that of the bus hence the answer.
Answer:
1500 J
Explanation:
Apparently, we're to assume that no energy is lost to friction or other effects. Then all of the energy the train has is due to work being done on it.
1500 J of work was done on the train
Answer:
(a)
(b)
(c)
(d)
Explanation:
The linear momentum is defined as:
(1)
Where m is the mass and v is the velocity
<em>a.) </em><em>A proton with mass moving with a velocity of . </em>
Replacing those values in equation (1) it is gotten:
So, it has a linear momentum of
<em>b.)</em><em> A 1.6 g bullet moving with a speed of 374m/s to the right.</em>
Notice that in this case it is necessary to express the mass of the bullet in terms of kilograms:
⇒
<em>c.) </em><em>A 8 kg sprinter running with a velocity of 11.8 m/s. </em>
<em>d.) </em><em>Earth () moving with an orbital speed equal to 29700 m/s.</em>
