Each cell has a size and shape that is suited to its job.
Answer:
11.6km
4.4km in the negative direction
Explanation:
Distance is the total length of path covered and traveled by a body.
So, for this car on a straight line;
Total distance = 8km + 3.6km = 11.6km
Displacement is the distance traveled along a path and the direction it takes.
It is a vector quantity with magnitude and directional attributes.
For this journey;
Displacement = 8km - 3.6km = 4.4km in the negative direction.
Answer:
Power, P = 480 W
Explanation:
It is required to find the power used by 4 A appliance that is plugged into a 120 V circuit for 4 minutes. Power used by an appliance is given by the formula as follows :
Plugging all the values we get :
So, the power used by the appliance is 480 W.
A larger amplitude means a smaller sound and a smaller amplitude means a larger sound.
Answer:
Paint can which is placed higher than other can will have more potential energy. Because according to the definition of the potential energy an object placed at some higher place when released to the ground will have greater impact than the one placed at some lower place. Painter can give the other can more potential energy by placing it at some height greater than the other cans.
Explanation:
To understand this, we need to understand the concept of potential energy.
Let’s assume two objects A and B. If A is placed at 10 meters above the ground and if B is placed 20 meters above the ground then according to the definition of potential energy, object B will have greater potential energy.
Similarly, in our question, we have paint cans, one is carried at some higher place through a ladder by the painter will have greater potential energy as compared to the one which is placed at ground.
Paint can which is placed higher than other can will have more potential energy. Because according to the definition of the potential energy an object placed at some higher place when released to the ground will have greater impact than the one placed at some lower place. Painter can give the other can more potential energy by placing it at some height greater than the other cans.
