Answer:
9.2 amperes
Explanation:
Ohm's law states that the voltage V across a conductor of resistance R is given by 
Here, voltage V is proportional to the current I.
For voltage, unit is volts (V)
For current, unit is amperes (A)
For resistance, unit is Ohms (Ω)
Put R = 12.5 and V = 115 in V=RI
Answer:
Explanation:
Given dish width= 48ft
Depth = 4ft
Using equation of a parabola
x²= 4py
48² = 4p 4
4p = 576
P= 144ft
Thus the the receiver should be placed 144ft from t the vertex
A time-varying magnetic field can be caused by fluctuating electric fields.
Answer:
74.529 m
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration due to gravity = 9.8 m/s²
For first ball
For second ball
As the displacement is equal
So, height of the building is 74.529 m
The Energy related to object motion.Potential energy most commonly refers to gravitational potential energy, which is energy associated with an object's elevation. For an object of mass m and elevation z, its potential energy is mgz where g is the gravitational constant .............. HOPE IT HELPS YOU :)
