Answer:

The correct answer is option-

Make an observation---> an indoor plant in a dark room withers faster than the same plant in a room with ample sunlight.
Ask a question----> Why do certain indoor plants die faster based on where they’re placed in the house?
State a hypothesis----> sunlight is probably essential for plants to grow and live.
Run an experiment---> get two potted plants, cover one with black paper. Place both plants outside in sunlight and see what happens to each plant after one week.
Analyze the results ---> the plant in the pot with black paper withered while the other plant was healthy.
Communicate the results to others---> Plants need sunlight to make food so they can live.

Explanation:

These statements are related to a process called photosynthesis.

Hypothesis is a well-substantiated opinion which explains any natural phenomenon occurring in nature.

A scientific question is a statement which can have real answers which can be tested based on the experiments performed.

Experiments are methodical procedures used to support the hypothesis.

Based on this the selected options are correct.

A motorboat maintained a constant speed of 15 miles per hour relative to the water in going 10 miles upstream and then returning

Lesechka [4]

Answer:

speed of current is 5 mile/hr

Explanation:

GIVEN DATA:

speed of motorboat = 15 miles/hr relative with water

let c is speed of current

15-c is speed of boat at upstream

15+c is speed of boat at downstream

we know that

travel time=distance/speed

$\frac{10}{15-c} +\frac{10}{15+c} = 1.5$

150+10c+150-10c=1.5(15-c)(15+c)

300=1.5(225-c^2)

300=337.5-1.5c^2

200=225-c^2

c^2=25

c = 5

so speed of current is 5 mile/hr

The position x, in meters, of an object is given by the equation:

LenaWriter [7]

Answer:

The SI units of A, B and C are :

$m,\ m/s\ and\ m/s^2$

Explanation:

The position x, in meters, of an object is given by the equation:

$x=A+Bt+Ct^2$

Where

t is time in seconds

We know that the unit of x is meters, such that the units of A, Bt and $Ct^2$ must be meters. So,

$A=m$

$bt=m$

$b=\dfrac{m}{s}=m/s$

$Ct^2=m$

$C=m/s^2$

So, the SI units of A, B and C are :

$m,\ m/s\ and\ m/s^2$

So, the correct option is (B).

Anyone plz help!! I need the answer of q-b !

Lady_Fox [76]

The coil is rotated rapidly in the magnetic field.
The magnetic flux linked with the coil changes and thus, an emf is induced which leads to the flow of current .

when the coil rotates and is in a position along the direction of the magnetic field, emf is maximum while when it is perpendicular to the magnetic field,emf is 0.

Thus an ac generator converts mechanical to electrical energy.It works on the principle of electromagnetic induction. The polarity at the supply terminals changes like.. 100 times a second if the frequency is 50 Hz(50 times+ and 50 times - )

hope it helps!
