Answer:
3.78 kWh
Explanation:
Power of incandescent bulb = 60 W = 0.06 kW
Power of fluorescent bulb = 15 W = 0.015 kW
Number of hours in a week if each day the light is turned on 12 hours
12×7 = 84 hours
Difference in power
0.06-0.015 = 0.045 kW
Multiplying with the number of hours
Hence, the fluorescent bulb will consume 3.78 kWh less electricity energy than the incandescent bulb.
D = vt
where:
v = speed
d = distance
t = time
Based on the formula, each quantity is directionally proportional to each other. Since we don't have enough numbers to work with, we will utilize our concept skills.
If the car travels half the speed, then the car is slowing down and covers a short distance in a certain amount of time than it did originally. So we divide the default distance by 2.
180 / 2 = 90
The new distance so far is 90 miles.
But now it takes the car 3 times as long to get to its destination. The longer it takes, the more distance you will cover. Multiply the current distance by 3.
90 * 3 = 270
The plus direction is going to go with the 10N to the right. Since the second force is applied in exactly the opposite direction, the net force 10 - 3 = 7 newtons to the right.
Answer:
A
The current through the solution is
B
The current is moving from B to A
Explanation:
From the question we are told that
The number of that move from A to B is
The time taken to move from A to B
Since the value of 1 charge is
The quantity of charge Q that flow from A to B is mathematically given as
The number of that move from A to B is
Since time taken to move from A to B is equal to time taken to move from B to A
The quantity of charge Q that flow from B to A is mathematically given as
The total quantity of charge is
The current flowing through the solution is
The flow is from B to A cause current flow from the positive terminal to negative terminal
Answer:
58.56 J
Explanation:
Since the formula for gravitational potential energy is:
GE = m x g x h - where m = mass (kg), g = acceleration due to gravity (9.81 m/s²), h = height (m)
GE= 3 x 9.81 x 2
GE = 58.86 J
