Answer:
Explanation:
The Answer is Concave. Concave images make images smaller, they refract the light rays in many directions, causing the original image to shrink. This is why shortsighted people wear concave lenses. Convex lenses, the other type of diverging lenses, cause the image to be larger, because it concentrates the image in a specific point. That is how a magnifying glass works.
Answer:
muscle
Explanation:
weight can also be added by muscle. not necessarily fat. so if you have a lot of muscle so that adds weight you can be very powerful but can mover very slow.
Kinetic energy can be used to develop electric energy which can be used as electricity.
<u>Explanation:</u>
The kinetic energy can be harnessed; much like some hydro power technologies harness water movement. A way to convert this kinetic energy into electric energy is through piezoelectric. By applying a mechanical stress to a piezoelectric crystal or material an electric current will be created and can be harvested.
Kinetic energy is also generated by the human body when it is in motion. Studies have also been done using kinetic energy and then converting it to other types of energy, which is then used to power everything from flashlights to radios and more.
Answer:
The force per unit length is 
Explanation:
The current carrying by each wires = 2.85 A
The current in both wires flows in same direction.
The gap between the wires = 6.10 cm
Now we will use the below expression for the force per unit length. Moreover, before using the below formula we have to change the unit centimetre into meter. So, we just divide the centimetre with 100.
Answer : The correct option is, (D) Velocity includes rate of change and direction.
Explanation :
Speed : Speed is defined as the distance traveled by an object with respect to the time taken. It is a scalar quantity that means it tell us about the magnitude of an object not direction.
Velocity : Velocity is defined as the rate of change of position of an object with respect to the time. It is a vector quantity that means it tell us about the magnitude and direction of an object.
The only difference between the speed and the velocity is that the velocity tell us about magnitude and direction but speed tell us about magnitude only.
Hence, the correct option is, (D) Velocity includes rate of change and direction.
