Answer: current = 10.25A
Explanation:
Toward = 240w
Alarm clock = 30w
Tanning bed = 720w
4 60 watts bulb = 60 * 4 = 240w
Total power = 240 + 30 + 720 + 240 = 1230w
Voltage = 120v
Recall that Power = current * voltage
1230 = current * 120
current = 1230/120 = 10.25A

Answer:
vertical distance, s = 0.16 meters
Explanation:
It is given that,
An amateur player is about to throw a dart with an initial velocity of 15 meters/second onto a dartboard.
Dashboard is placed at a distance of 2.7 meters.
Calculating time from velocity and distance i.e. 
Using second equation of motion for finding vertical distance :

Here, u = 0 (for vertical velocity )
s = 0.162 meters
or s = 0.16 meters
Hence, the vertical distance by which the player will miss the target if he throws the dart horizontally, in line with the dartboard is 0.16 meters.
Answer:
90m/h N
Explanation:
we consider janes velocity to the positive X axis so Vj=280km/s
and the final position a dot in on the graph r=294km, we find the x and y components:
294*cos(17.8)=280 X+ confirming our theory
294*sin(17.8)=90 Y+ or N and that's the winds' velocity.
Answer:
The magnitude of the average induced emf in the wire during this time is 9.533 V.
Explanation:
Given that,
Radius r= 0.63 m
Magnetic field B= 0.219 T
Time t= 0.0572 s
We need to calculate the average induce emf in the wire during this time
Using formula of induce emf



.....(I)
In reshaping of wire, circumstance must remain same.
We calculate the length when wire is in two loops



The length when wire is in one loop




We need to calculate the initial area

Put the value into the formula


The final area is



Put the value of initial area and final area in the equation (I)


Negative sign shows the direction of induced emf.
Hence, The magnitude of the average induced emf in the wire during this time is 9.533 V.
