12.8 rad
Explanation:
The angular displacement 
through which the wheel turned can be determined from the equation below:
(1)
where
Using these values, we can solve for from Eqn(1) as follows:
or
The answer would be c because it is talking about she wants to be in a good neighborhood
Answer:
38 cm from q1(right)
Explanation:
Given, q1 = 3q2 , r = 60cm = 0.6 m
Let that point be situated at a distance of 'x' m from q1.
Electric field must be same from both sides to be in equilibrium(where EF is 0).
=> k q1/x² = k q2/(0.6 - x)²
=> q1(0.6 - x)² = q2(x)²
=> 3q2(0.6 - x)² = q2(x)²
=> 3(0.6 - x)² = x²
=> √3(0.6 - x) = ± x
=> 0.6√3 = x(1 + √3)
=> 1.03/2.73 = x
≈ 0.38 m = 38 cm = x
Answer:
a transverse (sort of a plot of a sine or cosine graph, basically)
b longitudinal
c Electromagnetic (an electric wave and a magnetic wave travelling together at right angles to each other)
Explanation:
Answer:
A.
1. when the butter was placed on the spoon it slowly started to boil then began to melt.
2.the order was to heat the bowl, let it boil, then place the butter in.
3.The heat got from the water to the butter by placing it on the spoon then physically moving it into the hot bowl.
4.objects that do not conduct heat are called insulators.
B.
1. When the ice cube got placed into the water it immediately melted.
2.the water from the ice cube to the warm water as soon as it got laced it immediately melted.
3. the heat flowed straight up which made the ice melt really fast.
TABLE A: when I placed the butter in it melted a little bit slower than the ice cube but it still melted very fast.
TABLE B: when I put the colored one in the color slowly dissolved and pushed the color to the middle and the cube melted.
TABLE C: room temp water:75 degrees
cold water:50
hot water:315 degrees
TABLE D: when I blew out the candle the flame went but the smoke started to rise up.
TABLE E: the small beaker heated up quicker and I observed that the less amount of mass the faster it will heat up.
TABLE F: the black piece of paper heated up quicker and I believe its because the darker color the more mount of heat is attracted.
