Answer:
22 m/s
Explanation:
PEf +KEf =PE0 +KE0 →PE0 −PEf =KEf
−mgΔy= 1 mv2 →v= −2gΔy = −2(9.8 m/s2)(−25 m)=22 m/s
Answer: vf = 51 m/s and d= 112 m
Explanation: Solution attached.
<span>Resistance of automobile light is equal to 12 ohms.
</span>Resistance = Voltage / Current
where
Voltage = 12 volts
Current = 1.0 Amperes
Resistance = 12 volts/ 1.0 amperes
Resistance = 12 ohms.
Automobile light has 12 ohms resistance when it is connected to 12volts battery with 1.0 ampere current.
Answer:
c. from south to north
Explanation:
since we know that:
F = qv×B
where F is the force and in this case is pointed upward
where v is the velocity due east
the field must be due north by the right hand rule
Therefore, near the equator the magnetic field lines of the earth are directed north from south
