When you're playing Angry Birds on your smart phone, you likely don't realize how important science is to what you're doing. As the birds catapult through the air, science is probably the last thing on your mind. Aside from the physics involved in sending feathered projectiles flying through the air, there's a far deeper connection between science and playing your favorite games. That's because all technology, from smart phones to medical scanners to cars, are intimately connected with science. Without science, they wouldn't exist.
Science is the study of the natural world by collecting data through a systematic process called the scientific method. And technology is where we apply science to create devices that can solve problems and do tasks. Technology is literally the application of science. So it really is impossible to separate the two. In this lesson, we're going to go into a little bit more detail about how science and technology are related, including some examples.

Answer:
26.82m/s
Explanation:
Given
Mass = m= 0.4kg
Initial Velocity = u = 0
Charge = 4.0E-5C
Distance= d = 0.5m
Object Charge = 2E-4C
First, we'll calculate the initial energy (E)
E = Potential Energy
PE = kQq / d
Where k = coulomb constant = 8.99E9Nm²/C²
Energy is then calculated by;
PE = 8.99E9 * 4E-5 * 2E-4 / 0.5
PE = 143.84J
Energy = Potential Energy = Kinetic Energy
K.E = ½mv² = 143.84J
½mv² = ½ * 0.40 * v² = 143.85
0.2v² = 143.85
v² = 143.85/0.2
v² = 719.25
v = √719.25
v = 26.81883666380777
v = 26.82m/s
Hence, the object is 26.82m/s fast when the cart moving is very far (infinity) from the fixed charge

The crane does the work at the rate of (300 J) / (5 sec) = 60 joules per second.
That rate ... (work done) / (time to do the work) ... is called power.
That 60 joules per second is called 60 watts .
Answer:
60. W
