Laws explain observations.

Explanation:

The complete question is..

Which statements correctly describe laws? Check all that apply.

-Laws are created based on repeated experimentation.

-Laws are based on observations.

-Laws explain observations.

-Laws are factual statements.

-Laws can be changed or replaced

Laws are based on the results of repeated experimentation, and observation, and they describe or predict some phenomenon in nature. Laws can't be said to be factual, as they might be seen to be constrained, or restricted and might need to be extended by future observations. Established laws explain observations, and laws cannot be changed or replaced, but can be extended, to predict future observations.

An object 82 cm high forms a virtual image 4.1 cm high located 4.6 cm behind a mirror. Find the object distance.
ioda

Answer:

The object distance is 92 cm.  

Explanation:

let v be the image distance and h be the height of the image, let u the be the object distance and H be the height of the object.

then, the magification of the mirror is given by:

m = -v/u and m = h/H

so, -v/u = h/H

         u = -v×H/h

            = -(-4.6)×(82)/(4.1)

            = 92 cm

Therefore, the object distance is 92 cm.

in order to qualify for the finals in a racing event, a race car must achieve an average speed of 278 km/h on a track with a tot
Pachacha [2.7K]

The minimum average speed it must have in the second half of the event in order to qualify is 414.7 km/h.

<h3>What is average speed?</h3>

The average speed of an object is the ratio of total distance traveled by the object to the total time of motion of the object.

<h3>Total time taken by the car during the entire race</h3>

time = distance/average speed

time = (1.41 km) / (278 km/h)

time = 0.0051 hr

The car travels the first half of the race, d (¹/₂ x 1410 m) at 210 km/h;

d = 705 m = 0.705 km

t1 = 0.705/210

t1 = 0.0034 hr

<h3>time for the second half</h3>

t2 = 0.0051 - 0.0034 hr

t2 = 0.0017 hr

<h3>minimum average speed of the second half</h3>

v = d/t

v = 0.705 km / 0.0017 hr

v = 414.7 km/hr

Thus, the minimum average speed it must have in the second half of the event in order to qualify is 414.7 km/h.
