The correct option is SCALE.
This is because the experimental data you are interested in is mass and scale is the instrument that is used to measure mass. To use the scale, measure the mass of your water before you put it inside the sun and measure the mass again after you remove it from the sun. The difference in mass is the quantity of water that is evaporated.
There are different type of scale and the one that you use will depend on the size of the material that you want to measure.<span />
Answer:
B on edge
Explanation:
the piles of the magnetic field generated around the armature are attracted to the opposite poles of the permanent magnent. As the opposite poles align, the commutator reverses the current direction so like poles are aligned and the armature continues to spin
Very simple,Its all about calculating distance using the formula:
D = V x T
where,
V is the speed or velocity
D is distance
T is the time
In the given problem,there are two parts.
Lets do the calculations for both parts separately:
Part 1) Before the rain
Time = 130/95
= 1.37 hours <span> </span>
<span>Time taken after the rain = Total time - time taken before the rain </span>
<span> = 3.34 hours - 1.37 hours
= 1.97 hours </span>
<span>Distance covered after the rain = 1.97 hours x 65 km/h
= 128 km</span>
Hence,
<span>a) The total distance covered = 130 + 128
= 258 km
</span><span>b) Average speed = Total distance/Total time
= 260/3.34
= 78 km/h </span>
