Well, collinear points are points in same line,
that is a straight line is formed by connecting them,
here the line segment mE has point A,G,C,E so all these are collinear..
so, option c) E will be answer
hope it helped
Answer:
It controls the amount of current.
Explanation:
A resistor helps control and maintain the circuit which is it's main function.
D (it was produced by cyanobacteria)!!!
Answer:
Explanation:
Total weight
My weight+weight of belongings
660+1100=1760N.
a. Work done by the elevator to travel a total height of 15.2m
Using newton law of motion
ΣF = ma
There are only two forces acting upward, the weight and the reaction by the elevator
Also note it is moving at constant velocity then, a=0
N - W=0
Then, N=W
N=1760N
So, workdone is given as
Wordone, =force × distance
Work done=1760×15.2
W=26,752J
W=26.752KJ
b. Work done on me alone is still need to go through the same process but will remove the weight of the belonging
Therefore,
Weight now = 660N
And using the same equation of motion
ΣF = ma
Comstant velocity, a=0
N - W=0
N=W
N=660N
Then, workdone
W=F×d
W=660×15.2
W=10,032J
W=10.032KJ
Answer:
Properties of minerals are:
B) made of just one substance
C) made of at least two substances
Explanation:
Minerals & their Properties
Minerals are defined as the naturally occurring, solid inorganic chemical compounds. They have an orderly internal structure with definite chemical composition.
Fossils usually contain single or multiple minerals such as Calcite, Quartz, Phosphate etc. Sometimes minerals are visible in the crystalline form in fossils. So, we cannot say that minerals are made of fossils. Instead, fossils can be made of minerals.
According to the prime and standard definition given by scientists, minerals are usually composed of chemical compounds or multiple compounds such a Halite which composed of Sodium and Chlorine elements. But they can be made of just one substance or element.
Now talking about the tiny grains of sand, that are made of minerals. So, instead of saying that minerals are composed of tiny grains of sand, we should say that sand is made of minerals. The most common mineral which forms sand is Quartz. Sand has a versatile mixture of substances besides minerals.
