Answer:
The correct answer to the question is;
North
Explanation:
Fleming's left hand rule states that the direction of a magnetic field acting on a current carrying conductor is perpendicular to both the force acting on the current carrying conductor and the direction of the current.
Therefore, since the direction of the current is upward and a force is acting with a direction towards the east of the wire then the direction of the magnetic field is northwards.
Answer:
A
Explanation:
blue stars have a hotter sufarce arra, thats what makes them brighter.
Answer:
B. 1.55 × 10³ m/s
Explanation:
f = 3.02 x 10^6 Hz
wavelength = 5.13 x 10^-4 m
v = ?
v = f*lamda
v = 3.02 x 10^6 × 5.13 x 10^-4
v = 1.55 × 10³ m/s
Answer:
n = 1.76
Explanation:
According to the rule of ( n1 sin theta1 = n2 sin theta2 )
we know both angles so we insert them to the law and apply n1 = 1
so 1/2 = n2 sin 62 and we get the final answer
Answer:
The answer is potential energy
Explanation:
The potential energy is the energy possessed by a body by virtue of it position
For example the water at the top of the dam is being held at a height h above the bottom of the dam
Then the potential energy
PE= weight of the water* the height
PE= m*g*h
